What the FIM is going on

August 21, 2023 / / 0 Comments

If you have been doing PCI-DSS for some years, you have probably come across this term called FIM (File Integrity Montioring), which sometimes absolutely befuddles our customers. They generally think this is part of a wider SIEM or SOAR solution but not necessarily so. We’ll explore a little on why FIM is important, how it impacts PCI-DSS, some examples on configuration and what alternatives are there (if any). Here we go!

File Integrity Monitoring is the process of validating the integrity of operating system and application software files. It ensures that files have not been altered or compromised, whether maliciously or accidentally.

  1. Detecting Unauthorized Changes: FIM helps in detecting unauthorized changes to critical system files, configurations, and content files. These changes could be indicative of a breach, malware infection, or insider threat.
  2. Compliance Requirements: Many regulatory standards, such as PCI-DSS, HIPAA, and SOX, require FIM as part of their compliance criteria. It ensures that sensitive data is protected and that the integrity of the system is maintained.
  3. Preventing Data Breaches: By monitoring file changes, FIM can provide early warning signs of a potential data breach. It allows organizations to take proactive measures to prevent unauthorized access to sensitive information.
  4. Enhancing Forensic Analysis: FIM provides detailed logs of file changes, aiding in forensic analysis. It helps in understanding the nature of an attack, the affected files, and the potential impact.

Let’s pause for now and see if common Antivirus/antimalware can take over this compliance requirement without deploying a specific FIM. Why? Because all companies generally have some sort of anti-virus running in their systems and all companies are stingy in their compliance spending, so part of our job is to see if current technology can be sufficient to address compliance requirements. The difference between Anti virus and FIM boils down to the reason of their existence, their meaning to life and everything. Its 42!

While FIM focuses on monitoring the integrity of files, antivirus and antimalware solutions are designed to detect and remove malicious software.

  • Antivirus: Primarily targets known viruses and relies on signature-based detection. It may not detect unauthorized changes to files unless they are associated with a known virus signature.
  • Antimalware: Broader in scope, antimalware solutions target various malicious software, including viruses, spyware, and ransomware. Like antivirus, it may not detect subtle unauthorized file changes.

FIM complements these solutions by providing an additional layer of security, focusing on the integrity of files rather than just malicious content.

FIM also differs from Security Information and Event Management (SIEM) and Security Orchestration, Automation, and Response (SOAR) solutions. That being said, its common that these systems are bundled along with FIM solutions so while it’s possible that SIEM may have FIM, it might not be true that FIM has SIEM. They are like, maybe a dysfunctional family who sometimes get together over Chinese New Year reunions.

  • SIEM: SIEM solutions collect and analyze log data from various sources to provide real-time analysis of security alerts. While SIEM can include FIM as a component, it encompasses a broader range of security monitoring functions.
  • SOAR: SOAR solutions focus on automating and orchestrating security operations. They help in coordinating various security tools and processes. Unlike FIM, which is more focused on file integrity, SOAR aims to streamline security operations and response.

FIM makes its appearance in PCI-DSS v4.0 in requirement 10, specifically 10.2, 10.3,10.4,10.5,10.7 and further on in 11.5, 12.10 and A3.5.1.

In 10.2, PCI basically wants FIM to be part of the logging requirements in terms of what to capture, retention, response and so on. Make sure your FIM is configured to monitor the critical files, and the details of the FIM logs has user and process details, who is responsible for the change event and captured in real time. Ensure alerts are generated for change events by privileged accounts which can be further correlated to create an automated incident. Also, make sure changes to log file security settings or removal of log files triggers real time alerts, with exhaustive event details. All creation and deletion activities are captured as well, and all event details must be as per 10.2.2 for the FIM log files.

10.3.4 makes specific mention of FIM but there is some confusion to this requirement ” File integrity monitoring or change-detection mechanisms is used on audit logs to ensure that existing log data cannot be changed without generating alerts. “. Obviously if you try to monitor for changes in a log file and alert everytime that file is changed, your SIEM or SOAR will light up like Christmas. Because of the nature of log files, it is supposed to change! So to avoid the noise, ensure log files are monitored for changes in security settings, like permissions or ownership. If a log file is deleted, that is also an anomaly. And for those logs that are archived or digitally signed, if any changes are made to these, then your FIM should be able to detect it.

Requirement 11 doesn’t change much for V4.0 — it is the main portion for FIM in 11.5.2 and it remains pretty much the same. Requirement 12.10.5 does provide an explicit requirement to include FIM alerts into incident management and response. But you know that already, right?

There are plenty of FIM solutions out there. The common ones we see is OSSEC which is deployed together with Alienvault previously. Tripwire is also a well known name in the FIM arena. If you want to explore the inbuilt Linux version of FIM, auditd might be worth your time. For those unfamiliar with auditd, it’s a component that provides auditing functionality for the Linux kernel. It’s widely used for security monitoring, system troubleshooting, and compliance reporting. Configuring auditd might be intimidating to some at first, but here’s some rules to get you started, found in this link

https://github.com/linux-audit/audit-userspace/blob/master/rules/30-pci-dss-v31.rules

In summary, it covers the following areas (config has been omitted in this article, you can go to the site to get the details)

  1. User Access Linking (10.1): Implicitly met by the audit system.
  2. User Access to Cardholder Data (10.2.1): Requires a watch on the database, excluding daemon access. (Path to the database must be specified.)
  3. Logging Administrative Actions (10.2.2): Enable tty logging for su and sudo. Special cases for systemd-run and pkexec are included.
  4. Monitoring Privilege Escalation Configuration (10.2.2): Watches changes to /etc/sudoers and /etc/sudoers.d/.
  5. Access to Audit Trails (10.2.3): Monitors access to /var/log/audit/ and specific audit commands.
  6. Invalid Logical Access Attempts (10.2.4): Naturally met by PAM.
  7. Logging of Identification & Authentication (I&A) Mechanisms (10.2.5.a): Handled by PAM.
  8. Logging of Privilege Elevation (10.2.5.b): Monitors specific syscalls related to privilege elevation.
  9. Logging Account Changes (10.2.5.c): Watches changes to account-related files like /etc/group, /etc/passwd, etc.
  10. Time Data Protection (10.4.2b): Places rules to check time synchronization.
  11. Securing Audit Trails (10.5): Includes various measures to protect audit logs, limit viewing, prevent unauthorized modifications, back up files, and monitor log modifications.

So, there you go. Lastly, though since PCI v4.0 came out, the council seem to have made distinction of change detection mechanisms vs File integrity monitoring, stating that FIM is part of CDM, sort of like a subset. I suppose this gives a little more leeway for companies to implement other types of CDM other than FIM, although FIM is probably the only one that can address all the above requirements comprehensively and without any need for compensating controls. But just for some ideas, the below may be a list of other CDMs that can possibly address the FIM functionalities in part, automated or manual:

  1. Version Control Systems: These systems track changes to files and code within a development environment. They allow developers to see what was changed, who changed it, and why. Tools like Git, Subversion, and Mercurial are examples of version control systems that provide change detection.
  2. Database Monitoring Tools: These tools monitor changes to database schemas, configurations, and content. They can alert administrators to unauthorized alterations, additions, or deletions within the database. Tools like Redgate SQL Monitor or Oracle Audit Vault are examples.
  3. Configuration Management Tools: Configuration management tools like Ansible, Puppet, and Chef can detect changes in system configurations. They ensure that systems are consistently configured according to predefined policies and can alert administrators to unauthorized changes.
  4. Network Anomaly Detection Systems: These systems monitor network behavior and alert to changes that may indicate a security threat. They can detect changes in traffic patterns, unusual login attempts, or alterations to network configurations.
  5. Endpoint Detection and Response (EDR) Solutions: EDR solutions monitor endpoints for signs of malicious activities and changes. They can detect changes in system behavior, file activities, and registry settings, providing a broader view of potential security incidents.
  6. Log Monitoring and Analysis Tools: Tools like Splunk or LogRhythm analyze log files from various sources to detect changes in system behavior, user activities, or security settings. They can provide real-time alerts for suspicious changes.
  7. Digital Signature Verification: Some systems use digital signatures to verify the integrity of files and data. Any alteration to the digitally signed content would cause a verification failure, alerting to a potential unauthorized change.
  8. Cloud Security Tools: With the rise of cloud computing, tools like AWS Config or Azure Security Center provide change detection for cloud resources. They monitor configurations, permissions, and activities within the cloud environment.

Again, we would highly recommend that a FIM be used, but in the case where it is not possible in that environment, for instance Cloud environment, then other CDMs can be possible.

An Ode to the Invalid Certificate

April 19, 2023 / / 0 Comments

Once upon a time, in a not-so-faraway land of PeaCeEye, merchants, credit card transactions, online payments, payment gateways, POS terminals all lived in harmony. In this land, all citizens carry a trust symbol, held together by validation documents, called the Citizen Badge. However, PeaCeEye is now facing an existential threat. A threat shrouded in the cloak of validation, a false symbol of security and trust – called the Certificate. But, dear reader, beware! For this tale of caution and deception, and the Certificate, much like the elusive unicorn, while tangible, carries a false value – nothing more than a fabrication. A figment of imagination, conjured up by the minds of its idle creators, the Qessays.

You see, in the kingdom of PeaCeEye, there exists a council – a council of wise men and women who determine the rules and regulations that govern this realm. This council, known as the Secret Sorceror Council (SSC), has decreed that only three sacred documents hold the key to validation for the Citizen Badge – the Attestation of Compliance (AoC), the Report on Compliance (RoC), and the Self-Assessment Questionnaires (SAQs). Yet, despite the council’s resolute stance on this matter, a mysterious fourth document continues to emerge from the shadows – the Certificate.

Ah, the Certificate, a work of art crafted by the Qessays. You see, these Qessays were charged by the council to uphold what is truthful and right, and to ensure that all Citizens of PeaCeEye are identifiable by their Citizen Badges – The AoC, Roc and/or the SAQs. However, over the years, some of these noble Qessays have turned to the darkside and the sinister art of producing corrupted documentation, called the 4th deception, or the Certificate as it is now known. These dark Qessays have mastered the art of illusion, conjuring certificates out of thin air to dazzle their customers. They’ve become modern-day alchemists, turning mere paper and ink into a symbol of validation, which, in reality, is as weightless as a feather and as useful as a chocolate teapot. Or a fork and spoon when eating Chapati. It’s a thing of beauty, destined to hang on the walls of businesses, gracing them with its shimmering falsehoods.

But why do these Qessays continue to spin their webs of deception, offering their customers a document that has no merit in the eyes of the SSC? Something that even invalid citizens to PeaCeEye can procure? To unravel this mystery, we must dive into the murky depths of human nature. For, you see, people are drawn to shiny, pretty things, much like moths to a flame. A certificate, with its elegant calligraphy and embossed seal, is a testament to the allure of appearance over substance. It is a tangible representation of validation, regardless of its actual worth.

Moreover, the Certificate serves as a placebo, a sugar pill of sorts, which instills in businesses a false sense of security. It is a talisman that they cling to, convincing themselves that they are protected from the malicious forces of the World beyond PeaCeEye – the World called Cyberattacks. And, in the process, they become blind to the fact that the true power of validation lies in the sacred trio of documents – the AoC, RoC, and SAQs.

Now, one might argue that those who peddle these invalid certificates are merely fulfilling a demand. After all, the customer is always right, and if they desire a shiny piece of paper to adorn their walls, who are we to deny them? But, as the saying goes, “With great power comes great responsibility.” And these Qessays, as the gatekeepers of the citizenship of PeaCeEye, must hold themselves to a higher standard.

By offering these overvalued and useless certificates-that even the SSC had themselves admonished and had announced to the citizens to not place any value to them- these certificates not only betray the trust of customers but also undermine the very foundation of Citizen Badge. They turn the realm of PeaCeEye into a farce, a stage where pretenders masquerade as protectors, and businesses are lulled into a false sense of security. There are even Qessays who are not even involved in the process of validating an SAQ being answered; luring their customers to portals with questionnaires answered by the citizen themselves and then conjuring these certificates that look as if it has been validated by the Qessays, but instead are just self aggrandizing papers that has been only self validated by the person answering their own questions! In other words, the person becomes their own judge and jury and are able to produce a Certificate that looks as if they have been properly validated by a third-party Qessays. Amazing art! An ostentatious object of grandeur and magnificence, yet with all the actual value of a discarded banana peel withering in the Sahara sun.

But, dear reader, do not despair, for there is hope. You see, the truth has a funny way of revealing itself, much like the sun breaking through the clouds after a storm. And, as the truth about the invalidity of these Certificates spreads, businesses will begin to see through the veil of deception, and the demand for these counterfeit documents will wane. Qessays who persist in peddling these worthless certificates will find themselves exposed, their credibility crumbling like a house of cards.

In the meantime, we must not sit idly by, complacent in the face of falsehoods. Instead, we must raise our voices and spread the word, educating businesses on the true path to Citizen validation. We must sing the praises of the AoC, RoC, and SAQs, enlightening those who have been led astray by the allure of the invalid certificate. For it is only through knowledge that we can pierce the veil of deception and lay the mythical beast of the Certificate to rest.

So, let us embark on this crusade together, wielding the sword of truth and the shield of knowledge. As we march forward on this noble journey, let us remember the wise words of the SSC: “Trust, but verify.” Let us tear down the great wall of this Certificate, brick by brick, and replace it with a fortress built on the solid foundation of the council’s sacred trio of documents. And as we watch the last remnants of the Certificate crumble to dust, we will know that we have triumphed over the forces of deception.

We bid farewell to this Certificate, and to welcome a new era of transparency, security, and trust. An era where the mythical beast of the Certificate is relegated to the annals of history, and where the true power of validation is embraced, in all its glorious, council-approved forms. May the sacred trio of documents – the AoC, RoC, and SAQs – guide us on our path to a brighter, more secure future, and may the Certificate forever remain a cautionary tale of the perils of deception and the triumph of truth.*

** The above is written obviously in satire and tongue-in-cheek with absolute no journalistic value nor based on any real world reimagination and solely based on our absolute frustration at the continuous dependence and insistence from acquirers or banks to have our customers produce them ‘certificates’. In addition, some clients even go through self-service portals provided by QSAs and answer SAQ questions on their own, at the end of this process of self answering, a certificate is produced. Granted, the certificates do come with disclaimers in small prints stating that the certificate is actually based on self assessment and even admits that it isn’t recognised by the council.

But in reality, who actually reads the fine print?

In the end, anyone having gone through these ‘compliance’ portals, answering affirmative to everything would be able to procure these certificates and remarkably, some acquirers even accept them as proof of third party audit (which they are clearly NOT). Again, we are not stating that QSAs providing this service is doing anything wrong. There is nothing essentially wrong with certificates on its own, or QSAs providing these certificates as a simple means to show a company has undergone PCI-DSS compliance. But where it becomes a gray area is when there is too much dependence placed on these certificates to the point where even the AoC is rejected and acquirers insist on every company showing them these certificates. In this case, QSAs who are willing to provide so called certificates to companies without having undergone any assessment and only answering questions from the SAQ based on their own knowledge or whim – unless the QSA is willing to go through each question of each customer and validate these through evidence submission and review (the process called audit); then these creation of self signed certificates should be stopped. It’s akin to a banking website issuing a self-signed SSL cert on their own website and tell everyone to trust it. Does this happen in the world of e-commerce? No, it’s absurd. Then why is it different in the world of compliance? Why is this practice still allowed to prosper? How do we stop this practice?

We have been advocating removing certificates for years now from the PCI-DSS landscape and to have a more consistent and acceptable way to show PCI validation. Unfortunately, unlike the satirical tale above, this still eludes us. Drop us an email at pcidss@pkfmalaysia.com if you have any ideas and comments to this!

PCI-DSS v4.0 vs v3.2.1 Deepdive Part 1

March 17, 2023 / / 0 Comments

OK, now that we are well into 2023, the main question here is why isn’t the current assessments this year going into v4.0? Most of our customers are still doing their v3.2.1 for 2023, before doing 4.0 the next cycle. The answer is: Well, you can go for v4.0 if you want to. There’s really not much difference for now. The difference is probably more on the auditor side, as reporting requirements are different in V4.0. But from the client end, some of the scary changes like authenticated scans for internal vulnerability scanning, or updating of password complexity to 12 characters etc – these actually don’t come in force until March 2025. So there’s actually a grace period for v3.2.1 to v4.0 and another grace period for PCI v4.0 controls to be implemented, up to March 2025. Basically, anything past March 2025, the controls in v4.0 becomes Standard. No more compromise. Its like the biblical ten Commandments, except you have around 300+ commandments here. That’s a lot of chiseling on the rock by Moses.

Before we deepdive into v4.0, let’s set out the landscape a bit again, like unfurling a carpet or a mat before we feast into our metaphorical compliance picnic.

  1. Scope and Applicability

One of the key changes in PCI DSS v4.0 is the clarification of the scope of the standard. The new version provides more explicit guidance on how to apply the standard to different types of organizations, and it emphasizes the need for organizations to understand the scope of their cardholder data environment (CDE). This comes as a fairly significant change, as the initial pages of V4.0 is strewn with explanations of scoping and methodologies on how to define scope. It reads almost like they are trying to make up for lost time, and trying to cover all their bases, whereas in the previous version, just a cursory glance was done. PCI DSS v4.0 also provides guidance on how to identify and manage different types of risks. Risk has always been a difficult item to quantify in PCI. Because at the end, PCI is a result of a risk assessment anyway, done by the card schemes. It’s specifically to mitigate the risks they identified that the PCI program was born. So what’s the point of running a risk assessment in PCI-DSS if its already a standard? Well, PCI DSS v4.0 states that organizations should have a risk management program in place to identify and prioritize risks, and to take appropriate measures to mitigate those risks. Its a way of saying that while controls are required, how you address the controls are dependent on your risk assessment. Additionally, you can even opt to go above and beyond the PCI standard to address a particularly high risk area (although to find a company doing this is like finding the Lost Ark). Above the brownie points you would get from the QSA by showing you are a company keyed into your risk assessment practices; a risk assessment will likely help you identify other areas of concerns as well. The standard also requires organizations to have a process in place for identifying changes to their CDE, and for reviewing and updating their risk management program as needed. So to the point on whether the risk assessment is useful – yes. Whether it is critical to passing your PCI-DSS – well, I would say that depends a lot on your QSA. We’ve seen QSAs pass a bunch of colored coded excel sheets off as a PCI risk assessment easily.

2. New Control Objectives

PCI DSS v4.0 introduces several new control objectives to address emerging security risks. One of the key new objectives is to address the risks associated with cloud computing. The new version of the standard includes new requirements for securing cloud environments, including the need to assess the security of cloud service providers and to implement additional controls to secure cloud-based data. In v4.0, the word ‘Cloud’ appears 42 times in the entire standard. In v3.2.1, the word ‘Cloud’ appears as often as ‘NasiLemak’. Which is zero.

3. Password Requirements
PCI DSS v4.0 introduces new requirements for password management. We are in 2023 and we are still trying to remember all our passwords. PCI is now making our lives easier by introducing longer passwords! Great, now everyone just add incremental numbers behind your password from seven to twelve. The standard requires the use of multi-factor authentication for all non-console administrative access, this has already been evident in previous version. This just basically means that organizations must implement additional security measures, such as biometric authentication or smart card authentication, in addition to a password, to access sensitive systems and data

4. Encryption

The new standard maintains that organizations use more robust encryption algorithms and key lengths as per 3.2.1. Key management more or less remain as it is, but the biggest issue in v4.0 is the doing away with full disk or transparent encryption. We will do a deep dive in this later.

5. Penetration Testing and Vulnerability Management

PCI DSS v4.0 includes new requirements for penetration testing and vulnerability management. Among others is the requirement for Internal vulnerability scans to be authenticated whereas previously, this was a bit more gray area (actually not required). This could have potential impact especially for entities chasing a quarterly deadline, if you have a lot of systems in your scanning scope. So this makes the scoping a lot more critical. Because you can be sure the effort for internal scans are going to be going way up.

6. Remote Access

PCI DSS v4.0 includes new requirements for securing remote access to cardholder data environments. PCI requires organizations to implement multi-factor authentication for all remote access, and to use secure protocols, such as SSH or VPN, to access sensitive systems and data. While this remains, the other issue with 4.0 is the need to implement controls to prevent copy/relocation of PAN for all personnel unless there is a business need. We have a bad feeling about this. This could generally mean getting a DLP in place or a NAC in place to limit what can or cannot be done by users logging in remotely. There are solutions for these, but this needs to be planned and invested. The key word here is to ‘prevent’ not just ‘detect’, so this basically mean a proactive control in place to block these actions.

So in the next couple of articles, we will dive right into the changes for v4.0 in detail, including those requirements where it is stated “This requirement is a best practice until 31 March 2025, after which it will be required and must be fully considered during a PCI DSS assessment.”

We will also look into the SAQs and what has changed in the SAQs for those preparing to do self assessment in accordance to v4.0.

In the meantime, for any PCI related queries or any standards like CSA, ISO27001 etc, drop us a note at pcidss@pkfmalaysia.com and we will get back to you!

Trends for InfoSec moving into 2023

January 19, 2023 / / 0 Comments

When I was a kid, I used to watch this show called Beyond 2000 and imagined, if I lived to year 2000, I would be seeing flying cars and teleportation and space travel. Later on, I had to temper my expectation but was still filled with optimism when October 21, 2015 rolled around, at least, we would have a hoverboard to fool around with. At least.

We are now in 2023. No flying cars. No hoverboards or hovertrains and no flux capacitors to go back in time to make gambling bets. We do have a lot of information security issues, though, and while not really sexy enough to make a Hollywood movie around it, it’s still giving us enough to do as we ride into this new year on what trends we think may impact us moving forward.

To understand why information security has become increasingly important in recent years, we look at the sheer amount of sensitive information being stored and transmitted electronically, and shared in our everyday interaction. We share and give information without us knowing it, even. Everytime we browse the net, everytime we hover our mouse over a product, everytime we use our credit card to get your coffee or pay for Karaoke session, everytime we check our location on Waze:- the vast array of information and data is being transmitted and curated carefully by organisations intent on peering into our lives to make it “better”.

As information continues to grow, increasing amount of incidents follow. Some of the more high profile ones include

a) SingHealth – In July 2018, one of Singapore’s largest healthcare group, SingHealth, suffered a data breach where personal information of 1.5 million patients, including Prime Minister Lee Hsien Loong, was stolen. How was this achieved? The attackers had gained unauthorized access to the network and exfiltrated the data through a sophisticated method, which involved using a “well-planned and carefully orchestrated cyber attack” and a “spear-phishing” campaign in which the attackers sent targeted emails to specific individuals within the organization to gain access to the network. No matter how much investments we make in technology, the weakest link still remain the humans around it, especially those interested to click on links depicting a cat playing the piano furiously.

b) India’s National Payment Corporation of India (NPCI) – In January 2021, the NPCI, the company that manages India’s Unified Payments Interface (UPI) system, which enables inter-bank transactions, experienced a data breach. The breach was caused by a vulnerability in the UPI system that was exploited by hackers, who then used the stolen data to make fraudulent transactions. The incident resulted in a temporary suspension of the UPI system, causing inconvenience to millions of users.

c) Garmin – Back in 2021, Garmin, a leading provider of GPS navigation and fitness tracking devices, was targeted by a ransomware attack. The attackers used a variant of ransomware called WastedLocker, which encrypted the company’s data and demanded a ransom payment. The attack caused the company to shut down its operations, leading to widespread service disruptions.

d) SolarWinds – Ah, this was probably one of the largest profile cases of data breach in recent memory. It was discovered that a sophisticated cyber attack had breached multiple government agencies and private companies, including SolarWinds, that runs IT management software. The attackers used a vulnerability in SolarWinds’ software to gain access to the networks of the companies and organizations that used it, and used those accesses to steal sensitive information. The incident was attributed to a Russian cyber espionage group known as APT29 or “Cozy Bear”.

Many more information security issues will continue to occur well into this year and the next and the next. One of the burning question is how companies can keep up with this movement, and how we can remain vigilant.

One trend that is likely to continue into this year is the establishment of cloud computing. While previously we had AWS/Azure, we now see a larger array and options for cloud providers. Within the cloud itself, services being offered are replacing traditional needs for separate security functions like logging systems, authentication systems etc. As more and more organizations move their data and applications to the cloud, it will become increasingly important to ensure that this data is protected against unauthorized access and breaches. This will require more stringent security measures to improve encryption, multi-factor authentication, and continuous monitoring of cloud environments.

One of the more interesting ideas that has floated around is the use of blockchain technology for security. Blockchain is a decentralized, distributed ledger that can be used to securely store and transmit sensitive information. This can help in the C,I,A triad of security. Encryption for confidentiality, immutability in blockchain records to ensure integrity; decentralization of data to remove single points of failure to ensure availability. There could be many more uses, but it still remains an abstract for many organisations looking at this for their information technology. As such for basic implementation, this may be useful for applications such as supply chain management, where multiple parties need to share information in a secure and transparent way.

Another growing trend, as always, is the need for strong cybersecurity workforce. As the number of cyber threats continues to grow, it will be increasingly important to have a workforce that is trained and equipped to deal with these threats. This will require organizations to invest in employee training and development, as well as to recruit and retain highly skilled cybersecurity professionals. Professional training, a big industry in Malaysia, will continue to play a key role in enabling people to carry out their vital tasks within the information security landscape.

Another abstract trend we often hear, deals with the Internet of Things (IoT) devices. In short, IoT refers to the growing network of physical devices, vehicles, buildings, and other items that are embedded with sensors, software, and connectivity, allowing them to collect and exchange data with each other. The example we always see is that fridge telling us we are running short on milk and placing an order to get milk for us. But IoT is happening whether we like it or not. Healthcare will be heavily dependent on it as information is exchanged with digital systems across nationwide healthcare systems; manufacturing of course is putting more traditional systems onto the network to integrate with automated processing tools; transportation is getting more digitized than ever, car manufacturers now looking not just to hardware but to cloud enablement of software running in cars. Even wearables, fitness apps, smart homes etc are impacting end users in more ways than we can imagine. It’s coming. or it’s here – eitherway, we expect 75 billion devices to be connected over IoT by 2025.

Another trend we like to see more in 2023 is the use of artificial intelligence and machine learning for security. These technologies can be used to detect and respond to cyber threats in real-time, as well as to analyze large amounts of security data to identify patterns and anomalies that may indicate a potential attack. We traditionally have threat intelligence but the time to respond to threats were still lagging behind, dependence on human intervention and decisions. With automated systems, more advanced rules and correlation of multiple information points, actions can be orchestrated through a more meaningful, machine learnt manner as opposed to depending on manual rules and signatures.

While not the most sexy or interesting, where we want to see improvement and a trend to get better, would be to improve and make more effective incident response plans. With the increasing number of cyber threats and attacks, it is critical that organizations have the ability to quickly and effectively respond to security incidents. This will require organizations to have detailed incident response plans in place, as well as to regularly test and update these plans to ensure that they are current and effective.

One trend we want to see more, especially in our accounting and auditing industry, is the adoption of security automation. This will involve the use of software tools and technologies that can automate various security tasks, such as vulnerability management, incident response, and threat intelligence. Implementation of tools such as Ansible has been done in our organisation, providing at least a first layer of understanding configuration and management of systems. With more automation, this will help us to more efficiently and effectively protect and respond against cyber threats.

Finally, some of the things we hardly talk about in information security is how much more integrated infosec needs to be in the field of humanities. A lot of us approach info sec from a technical viewpoint, which is great but perhaps a more effective viewpoint should be from the views from humanities. The humanities can play several roles in information security, including providing a broader understanding of the social and cultural contexts in which security threats occur, assisting with the development of effective communication strategies for raising awareness and educating the public about security risks, and helping to design user-centered security systems that take into account the needs and behaviors of different groups of users. Additionally, the study of ethics in the humanities can be used to inform decision making and policy development in information security. An example would be how implementing more stringent security monitoring may impact the innate need for privacy within employees – where, though the technology is sound and good and the intent is well thought of, organisations may still end up pushing out policies and technology that people will revolt against as opposed to embracing. This is not a field we often think of, but moving forward, it’s worth dwelling on and indeed provides us a more holistic way on how infosec can be part of our lives.

This isn’t so much of our traditional compliance article, but it’s always interesting to try to peer into a crystal ball and see what’s ahead and then at the end of the year see what has been proven more correct or wrong in our trends prediction.

Introduction to ISO27001 (Information Security Management System)

January 16, 2023 / / 2 Comments

One of our goal for 2023 is to provide more content in our technical articles, not just on PCI-DSS (which we have been primarily writing on), but on other areas where we are focused on. In fact, customers often express a little surprise when we tell them that we also do a lot of consulting on ISO27001, SOC1, SOC2, CSA, ISO2000 and pretty much the main technology compliances, even extending to NIST 800-171 and lesser known standards out there. They primarily associate us with PCI-DSS, which, while it is true it still is our main business, serves as a reminder to them and to us that we often end up forgetting to market our other services.

The other branch where we are very active in is in ISO27001. Like PCI-DSS, we do not do the certification (we leave that to the certifying body), because we often find ourselves helping our customers implement the system itself, and are generally very much involved in building policies, framework and guiding them through the standard.

Before we jump too deep in, let’s wade a bit into the standard for this article.

ISO 27001 is an international standard that outlines the requirements for an information security management system (ISMS). A company can certify to ISO 27001 by implementing the standard and undergoing an audit by a third-party certifying body.

Here are the steps a company can take to certify to ISO 27001:

  1. Understand the standard: Familiarise yourself with the requirements of ISO 27001, including the management system and control objectives.
  2. Perform a gap analysis: Compare your current information security practices to the requirements of the standard to identify any gaps that need to be addressed.
  3. Develop an ISMS: Implement an ISMS that meets the requirements of the standard. This should include policies, procedures, and controls that cover all aspects of information security, including risk management, incident management, and compliance.
  4. Implement the ISMS: Put the ISMS into practice by training employees, updating procedures, and monitoring compliance.
  5. Conduct internal audits: Regularly conduct internal audits to ensure that the ISMS is being effectively implemented and to identify any areas for improvement.
  6. Seek certification: Once the ISMS is fully implemented and operational, seek certification from a third-party certifying body. The certifying body will conduct an audit to ensure that the ISMS meets the requirements of the standard.
  7. Maintain certification: Once certified, it is important to maintain compliance with the standard by regularly reviewing and updating the ISMS, and undergoing periodic surveillance audits.

Certifying to ISO 27001 demonstrates to customers, partners, and regulators that a company is committed to managing and protecting sensitive information, and that it has implemented best practices for information security.

Like all standards, you should go in with your eyes open, as there are several major challenges that companies may face when attempting to certify to ISO 27001, if we were to address it step-by-step in the process described above:

  1. Understanding the standard: The standard is quite comprehensive, and it can be difficult for companies to fully understand all of the requirements and how they apply to their specific organization. The standard doesn’t apply the same for all companies, so beware. It’s not a checklist, either or a cookie cutter standard where you just take lock, stock and two smoking barrels all the requirements and force it down your own throat. There is the risk assessment process, the selection of controls, the statement of applicability – all of which, you can do it on your own or we can help you navigate through the forest of information.
  2. Conducting a gap analysis: Identifying gaps in an organization’s current information security practices can be a challenging task, especially for larger companies with complex systems and processes. Additionally, multiple departments make it more formidable to define scope. Unlike PCI-DSS (which is very definite in terms of scope), the expansion and boundaries of the ISMS can be much less clear.
  3. Implementing an ISMS: Developing and implementing an ISMS that meets the requirements of the standard can be a significant undertaking. It may require significant changes to existing policies and procedures, as well as the implementation of new controls. Expectations, time-resources are often overlooked as well and we have experience where companies go half in and then decide the water is too cold and they back off. It’s always important to set the tone early, set it from the top, which brings us to the next point.
  4. Employee buy-in: Getting employees to understand and buy-in to the importance of information security and to follow the new policies and procedures can be a significant challenge. By far, like any other standard, it’s not really a technical hurdle that often foil a company seeking certification, but human hurdle. People are too busy, or too focused on other areas; they simply do not have time. Without a top-down push, you will find a significant impediment convincing people that this is important. It’s a cliché but it’s true: the project is not an IT project, but a business project.
  5. Cost: Implementing an ISMS and seeking certification can be costly, especially for small and medium-sized businesses. Many a times, potential customers go in with the idea that a budget of RM10k would be enough to go end to end. Now, I am not saying it’s impossible; but it would be very difficult to properly implement an ISMS without a proper budget. The range may vary, true, depending on how much work you can do on your own, but in general, like PCI-DSS, you probably would have to look at a fairly generous budget if this is your first time undertaking ISMS and you do not have an internal team to handle the compliance.
  6. Maintaining compliance: Once certified, it is important to maintain compliance with the standard by regularly reviewing and updating the ISMS, and undergoing periodic surveillance audits. This can be a significant ongoing effort, and it requires dedicated resources to ensure ongoing compliance. The cycle goes through surveillance audit 2 years after the initial certification and re-certification on the third cycle. Survelliance audit is still a fair bit of work as you need to demonstrate compliance to the ISMS standard over the period of the cycle (12 months).
  7. Finding qualified and experienced team: Identifying a qualified and experienced consultants who understand the process and how auditors work can be a big help. Understanding how the auditor conducts a thorough audit and provide valuable feedback on the ISMS can be a challenge, especially for companies that fairly unique in their process or have specific industry requirements.

By understanding these challenges and developing a plan to address them, companies can increase their chances of successfully certifying to ISO 27001. Contact us at avantedge@pkfmalaysia.com for more information on how we can help you begin your ISO27001 journey.
