PCI-DSS For Software Developers

August 22, 2019 / / 0 Comments

Of late we have been receiving numerous calls from software developers requesting us how on earth do they become PCI-DSS certified.

It’s never easy to explain over the phone, especially with misconceptions that PCI-DSS is a license, or a software, or a solution, or some sort of exam or some other thing. And also, how do we go about explaining to them that technically they don’t (or can’t) be PCI certified as a software vendor, but they can opt for PA-DSS or the new Secure Software Standard from PCI.

So the first thing to ask is (assuming this application/solution is handling credit card information):

a) Are you developing software only and selling that software to your customers?

b) Are you developing a solution where you are hosting and managing and allowing clients?

If it’s a), applicability of PCI-DSS is simply on your customer that is buying your software, not on you as a company. After all, you generally don’t handle credit card – your customer does. However, your software is likely in scope for their PCI-DSS assessment, so there could be an instance where you need to participate in your client’s assessment or to develop your software in a manner where it would be “PCI Compliant”. Developing a PCI compliant software doesn’t make it certified, but it does assist in helping your clients getting certified. An example would be to develop your solution with logging capability and able to log to a central location. Another example is your solution being able to integrate with AD, or to have PCI compliant password policies (session timeouts, password expiry etc). Other examples are to ensure there is Role Based Authentication and Authorisation. Or ensuring encryption is properly done for data at rest and in transit. By doing these doesn’t make it immediately PCI certifiable – but it does provide your client with less headache.

If it’s b), then yes, you are not considered just a software developer but a service provider. You are providing SAAS, so generally that makes you responsible for the day to day security of card data in behalf of your client. In that case, PCI-DSS is able to be applied to you on your solution and your process.

As with PA-DSS, the new Secure Software Program applies to the following software:

Software products involved in or directly supporting or facilitating payment transactions that store, process, or transmit clear-text account data.

Software products developed by the vendor that are commercially available for sale to multiple organizations.

So all the CRM systems, call systems, in house systems, customised systems are all not eligible for PA-DSS or the new program. This is typically in line with what has always been, anyway.

So that leaves us back to square one. What happens if you are not eligible for PA-DSS or Secure Software program and you are just a software developer and NOT a service provider, but your client is insisting on you being PCI-DSS certified?

Well, hopefully you can explain to them or point them out to this article. Another option you can have is to say you have developed your software that is compliant to PCI requirements. The following list shows what it should take to address PCI compliance (not comprehensive):

1.      Requirement 2 – Ensure no clear text for administrative access

2.      Requirement 3 – Application is transmitting /store and strong encryption needed

3.      Requirement 4 – Application must encrypt when transmitting over public network

4.      Requirement 6 – Software development process – secure code review, remove test data before rolling to production,  ensure application is patched, prompt when bugs are discovered.

5.      Requirement 8 – ensure the application can support PCI DSS password requirements, password is encrypted at rest and transmission

6.      Requirement 10 – the application is capable of sending logs to the SIEM, Application penetration testing is conducted and documented what methodology of testing is used.

Requirements affecting Software: Sample Evidences
For all system components in scope (servers, network devices, applications, databases, etc.) and POS devices, provide evidence of strong cryptography being implemented (ssh, TLS 1.2 or later, RDP over TLS etc.)
Provide the following for all filesystems, databases and any backup media
– Details on method (encryption, hashing, truncation, tokenization) being used to protect covered information in storage
– Evidence (screenshots or settings) showing  covered information is protected
Provide evidence of encryption being used for transmission of in-scope data over any open or public communication channel (i.e. Internet, Wireless network, GSM, GPRS, VSAT technology etc.). Encryption must confirm to strong industry standards.
For the selected sample, provide evidence of,
– Current patch levels
– Patches being deployed in a timely manner
Provide secure software development process document in accordance with industry best practices
Provide a recent secure code review report for an application that stores, processes or transmits covered information.
Provide a document that outlines
– the process for generating test data to be used in lower (test/development) environments.
– the process for removing test data and test accounts prior to moving the system to higher (production) environment.
Provide 4 sample change request (2 for software modification and 2 for security patch implementation) from the last 6 months.
Provide the following from a secure code training perspective
– Material used for training
– Attendee list showing that all developers are covered
Provide evidence of logical access account and password features to include,
– Account lockout policy
– Account lockout duration
– Session timeout policy
– Password length
– Password complexity
– Password history
– Password expiry
Provide evidence that passwords (for platform and/or consumer applications) are encrypted during transmission and storage.
Provide the audit log policy settings.
Provide actual event logs for each of the platforms identified in the sample.
Provide a documented methodology being used for penetration testing.
Provide internal penetration test report.

You would get stuck if your clients want to see the PCI-DSS certification, which obviously you won’t have. In this case, the only way forward is to talk to them saying it’s not possible for you to be PCI certified in that sense. If you want, you could actually engage a third party auditor or even a QSA to assess the application based on PCI requirements. You won’t get a certificate for PCI, but at least you have a third party attestation or report, which hopefully should be enough.

Another option is to just get a hold of us at pcidss@pkfmalaysia.com and we can maybe provide a bit more persuasion to your client in accepting your application for PCI-DSS!

PCI-DSS Full Disk Encryption Part 2

May 31, 2019 / / 0 Comments

In our previous article we wrote on how Bitlocker can possibly be used as a full disk encryption solution for PCI-DSS.

One of the key things is for the following statement to be complied to:

If disk encryption is used (rather than file- or column-level database encryption), logical access must be managed separately and independently of native operating system authentication and access control mechanisms (for example, by not using local user account databases or general network login credentials). Decryption keys must not be associated with user accounts.

By enabling TPM itself doesn’t guarantee that the native authentication is separated from the logical access to the encrypted file system.

The below basically enables TPM with PIN to ensure that there is an additional logical access that is required to comply to PCI-DSS.

So overall, this means that Bitlocker needs an extra authentication when the server restarts. As the policy states, either a passphrase or USB will be required for the startup, and from PCI perspective, this addresses the separate authentication requirement.

Of course the major discussion here is what is compliance and what is practical security?

Because when was the last time you actually restarted your server? The fact is that full disk encryption is only as useful as it is to protect data on the disk when the system is not running. When the server is running, access to the disk remains open and therefore, we see unprotected PANs with their pants dropped (so to speak).

We are not saying that bitlocker cannot comply to 3.4.1 of PCI. We are saying probably PCI might be better off relooking at this 3.4.1 and clarify the ‘spirit’ of this requirement. At the end, we are concerned with loss of PAN. We are concerned with the fact that files may be taken away, siphoned away through a variety of means – either through the network, or USB, or photos on your phone etc.

The problem with Full Disk Encryption is that even if we do have separate authentication to boot up into the server, once it’s booted and once authenticated separately, the full disk encryption no longer does the job of ‘rendering PANs unreadable where they are stored’. The argument thus comes about that once that occurs, then whoever is reading those PANs are authorised users already with business requirements to view those PANs.

In our opinion, there needs to be much more security surrounding these servers with PANs that use full disk encryption. Access must be limited again to only those with business justification, and not be used for multiple purposes and especially not for non-PCI usage. Logical access, hardening, logging and monitoring obviously needs to be in place. Protection of the PIN must be in place, and changes of PINs based on PCI-DSS expiry policies.

The comfort level of FDE vs say, file encryption or even folder encryption is much less. Whether it meets 3.4.1, if done properly, it clearly does. But is it truly secure? Therein lies that discrepancy between compliance and security. It ticks the checkbox (for now, unless PCI alters it in 4.0), but from a security standpoint, there is a lot of risk surrounding it.

If you use FDE, don’t expect your QSA to just take it lying down. Most likely further queries will be made and some may deem it even insufficient in itself to address the risks of PAN being compromised and may request additional controls on top of it.

If you have further queries on FDE or any compliance programs like PCI, ISO etc, drop us an email at avantedge@pkfmalaysia.com and we will attend to it immediately!

PCI-DSS Full Disk Encryption Part 1

May 25, 2019 / / 0 Comments

In PCI-DSS, one of the most difficult requirement to get through would be Requirement 3, that deals with stored credit card information and how to protect it. Aside from Requirement 10: Logging and Requirement 6: Software, Requirement 3: Storage makes up a bulk of the remediation effort and cost of PCI-DSS.

The excerpt ominously states at the beginning: Protection methods such as encryption, truncation, masking, and hashing are critical components of cardholder data protection. If an intruder circumvents other security controls and gains access to encrypted data, without the proper cryptographic keys, the data is unreadable and unusable to that person. Other effective methods of protecting stored data should also be considered as potential risk mitigation opportunities. For example, methods for minimizing risk include not storing cardholder data unless absolutely necessary, truncating cardholder data if full PAN is not needed, and not sending unprotected PANs using end-user messaging technologies, such as e-mail and instant messaging.

It goes without saying that if you have credit card information on file for whatever reason, it would be a good time to relook at the necessity of it. If you don’t need it, get rid of it, because the cost of maintenance and remediation may not be worth whatever value you think you are obtaining from storage of card data.

If you do need it, well, PCI provides a few options for you to protect it: Encryption, Truncation, Masking and Hashing. In this series of articles we will be looking into encryption and more specifically Full Disk Encryption.

Encryption itself deserves a long drawn out discussion and the types of encryption – you have applications doing encryption through the application library, you have database encryption like TDE, you have file encryption or folder encryption, you have full disk encryption. One part is the encryption methodology. The other part of it is the encryption key management. The latter is the one that usually throws up a headache.

We will be exploring Full Disk Encryption or FDE, and where it can be implemented to comply to PCI-DSS.

There is a specific part in 3.4.1 stating:

If disk encryption is used (rather than file- or column-level database encryption), logical access must be managed separately and independently of native operating system authentication and access control mechanisms (for example, by not using local user account databases or general network login credentials). Decryption keys must not be associated with user accounts.

So aside from the encryption being strong encryption and key management being done properly, PCI says, there are a few more things to be aware of for full disk encryption:

a) Logical access must be separate and independent of the native OS authentication

b) Decryption key must not be associated with the user account.

What does this mean?

Let’s look at Bitlocker for now, since that’s everyone’s favourite example.

Bitlocker has gone through a lot of stick probably because it’s a native Microsoft offering. Maybe. I don’t know. The fact is Bitlocker is able to use 128 or 256 bit AES so basically, in terms of strong cryptography, it’s possible. It’s the key management that’s the issue.

For key management, the recommended usage with Bitlocker is to use the Trusted Platform Module version 1.2 or later. The TPM is a hardware in your server that somewhat acts like a key vault or key management module, to simplify it. It offers system verification to ensure there is no tampering of the system at startup. Beginning with Windows 10, version 1803, you can check TPM status in Windows Defender Security Center > Device Security > Security processor details. In previous versions of Windows, open the TPM MMC console (tpm.msc) and look under the Status heading.

Bitlocker can also be used without TPM, although that means the system integrity checks are bypassed. It can operate along with Active Directory, although the newer versions of bitlocker doesn’t store the password hash in AD anymore by default. Instead a recovery password can be stored in the AD if required.

With the TPM, it’s still not the end of it, because we need to make sure that there is a separation of authentication for bitlocker to operate. In this case we will look to configure it with a PIN (which essentially is a password that you know).

First of all, let’s see what at the end we should be seeing.

So at the end you are basically seeing both file systems being encrypted. I’ve been asked before if all volumes need to be encrypted, and the answer is no, because bitlocker can’t do that anyway. Your system drive can’t be encrypted. So for PCI, it makes sense NOT to store card data in drives that are not encrypted.

The next thing we need to check is to ensure your set up has fulfilled the strong encryption requirement of PCI-DSS:

So you have a few things to ensure that strong crypto is enabled and key protectors are in place. So what you have is bitlocker now enabled. You also basically need to ensure you properly document the key management policy – include in AES256 or 128 that you are using, which drives are protected, key expiry date.

Keep in mind also the following:

FVEK (Full Volume Encryption Key) as DEK and VMK (Volume Master Key) as KEK.

FVEK stores in Boot sector (Volume meta data) in hard disk and VMK stores in TPM chip PCR register (it’s a Hardware chip which place in Motherboard).

In general, the above would fulfill PCI requirements. In our next article, we will write out on how logical access to the encrypted file system can be separated from the native OS authentication mechanism.

The Criticality of Project Management

May 2, 2019 / / 0 Comments

Project management over the years have gone through somewhat of a bad rap for technology projects, especially. They always seem like a luxury afforded by management, and whenever things go south in a tech project, the first stop for blame is always on the project manager. It’s a tough life. On one hand you need to appease the forces that hold the budget (the business) and on the other, you need to deal with a bunch of geeks who are talking binary stuff and whom you know would rather not have you in the room because you don’t talk tech as much as them.

We used to have a Project Management Office, receiving work from other large projects looking for business analysts, project leaders, program managers etc. It’s not cheap upkeeping these guys, what’s with their PRINCE and PMP certifications and their training and hours. The problem was also when the project ended, then basically we had to go look for other projects to take them on. It’s an expensive affair, unless you have a constant pipeline of internal or external projects to keep them busy. The thing was, we noticed project managers tend to stay as project managers. You couldn’t get them to go into tech audits, or develop software or do compliance work. At least, for the ones we hired.

In the past, Project Managers are fairly agnostic in terms of technical capability. They have a set of domains they are good at (whether they are good at telco projects, compliance projects, migration projects), but overall, the discipline more or less remains constant. Methodologies used by these managers include lean, SCRUM, Agile etc, or simply PMI/PMBOK guidelines, which some of our managers tend to gravitate to. But aside from this basic competency of managers, there is inherently a personality that project managers need to have. Leadership is obvious, decision making capability, the ability to stand strong when being questioned and able to communicate the project properly. The ability to pull people together, from technical to consultants to internal business, and yes, the inherent charisma that one must have to become a successful project manager. He or she needn’t be the most technical in the room, but they must be able to sniff bullshit and weed it out. Time, budget and quality are the basic triangles of forces that need to be met, and good project managers are aware of this.

Due to cost and lack of demand, we shuttered our PMO a few years back, but our guys still practice basic PM work in our compliance project, and in some smaller companies, we actually end up taking the informal role of the project leads. We wouldn’t call ourselves project managers, because not everyone who calls themselves project managers are actually project managers. However, for larger companies, we do defer to the project manager in charge, and in our time we have had some experience with some of the best in the business, and some of the absolute worst. The problem is because being a good PM or absolute garbage is so difficult to assess.

It MAKES A HUGE difference who you put as a project manager. It spells either success or complete doom to your project the moment you assign a good or a garbage project manager.

For a compliance like PCI-DSS, there are some specific traits a manager should have, as PCI is a fairly technical project. And most PCI projects tend to drag on past 4 months or so. Some even a year plus. It does require a fair bit of technical knowledge, persistence and goodwill to successfully manage the project. Here are some of what we observed, and having experience good ones, and the bottom of the barrel type of project managers, we can probably give a fair opinion of what are the points of success (between good manager (GM) and hapless manager (HM)):

a) Technical Capability

This is more of a trait than a skill.

The GM know they don’t need to be experts, but they also know they need to put their backs and time into understanding the whole thing and trying to absorb the technical matters of it. They would attend training sessions and they would ask very good questions. The hapless managers go: OK, everyone knows their spot here. Consultants, I will look to you to answer all PCI related questions. I am here to gather information for all parties, so I want everyone to come for every meeting we are going to have moving forward.

The hapless one basically just comes in, fires off a few questions on project matters, and then sidles down and constantly have a far away look in their eyes when we start talking about the project tasks and updates. Or glued to their phones or laptop, furiously typing out stuff with their brows knotted up. Their strategy is that everyone else will carry their own load so they don’t need to know anything technical because they are too busy with other more important things, like buying food for their cats online. Occasionally, they bark out some orders here and there but you can tell, they know jackshit. After 4 – 5 sessions, they are still clueless and that’s when they start losing grasp of reality, and if the consultants are not available, the whole project is stuck, and then they move into the stage of looking to blame people for their ineptitude. Oh yeah. We have had plenty of these experiences for sure.

b) Communication

This seems a given, and a good manager ensures everyone is on the ball and the scoreboard is known to all. They know how to manage downlines (the people that need to get things done), horizonlines (the peers who are managing other downlines) and uplines (the business or sponsors pressuring the project). This innate ability isn’t bestowed on the hapless one. The hapless manager’s basic modus operandi is to take whatever the team gives, and being questioned by uplines and peers, decide that they don’t know how to explain it and comes back to the team again to ask for more information on how to deal with the questions. There is a complete lack of awareness in these managers that they are unable to overcome. They are unable to argue their points succinctly and always give in when there is pressure. Because of their lack of skill and understanding, they have no clue what positions to take and often waste the entire project timeline by going back and forth hopelessly like grass (or lalang) swaying in the wind.

c) Responsibility

One of the true strengths of character is when things are not going right, the good ones take up the responsibility of the situation and face the issues head on. The hapless ones find a way out, and find a way to blame others. To them, it’s always someone else at fault and never them. This stems from their utter lack of confidence in the project, that the only way they can reverse the situation is by saying, “It’s not my fault.” They usually will turn to consultants, as they are external to the company, and seek to pin the blame on them. It’s tough, but it is what it is. Most companies, given the choice of an external party and an internal person, would side with their own regardless of facts.

d) Time Management

The LLB (Look Like Busy) Trait is a big problem with these hapless managers. Because of their lack of a), b) and c) above, they are running around like headless chickens, being pulled from one meeting to another, unable to resolve any issues properly. So their heads are constantly in their phones or laptops instead of properly leading the project. Firefighting, or looking to assign blame. You can also tell when they are not able to manage meeting times. Many times, we have received calls from project managers requesting either immediate meeting at their office, or to come onsite within the next day and they wail because we tell them we are either overseas or assigned to other audits and we can do a phone. Most don’t understand that (unless we are properly paid and engaged), we are not their outsourced compliance unit so they blame us for non commitment. We are their consultants and there is no service level that requires us to stay in the clients office all the time for their beck and call. Unless, again, if they pay us, but most don’t pay for consultants to sit down and wait for inept project managers to scramble around looking for ad-hoc meetings.

Because they are scrambling and blaming instead of working,these PMs now think they are utterly important because they are so busy, but the fact is because of the ineptitude, they are being forced to seek responsibility, communicate or have technical explanation of the project – all which they are unable to do. So it’s one excruciating, meaningless and useless meeting after another. It’s horrible to exist in that manner for a career, but we’ve seen this many times.

Once you solve a), b) and c), Time Management solves itself.

Bonus points: While this may not be always true, the way project managers approach meetings and projects can actually say a lot. If a PMP or PRINCE PM comes in, there is usually a methodology on the table, tools and actual project management software they utilise for reporting. They are able to standardise our reports to a point where it goes straight to the point and to what they know their uplines need to know. Some hapless PM comes in, not certified in anything, not having knowledge of any tools, software or methodology, but basically armed with an excel sheet they took from another project manager who took from another project manager who used it to make sandwiches. That’s how senseless we see some of these methods and tools sometimes an we just look at everyone across the table and everyone goes like: “What is going on?”

In conclusion, never underestimate the importance of Project Managers, especially in a long drawn project like PCI-DSS. While we have known some excellent ones in our time, we have also worked with yahoos out there that single-handedly managed to trainwreck projects. From this article, it may seem our experience is more on the latter, but the opposite is true – we have the privilege to have worked with some really excellent ones that have also helped us get better, over these years. They are absolutely precious resources in a project, trust me. It’s just that when we do face one or two hapless PMs, it stands out a little bit more because we are so used to working with good ones!

Yes, we have shuttered our PMO as an advisory a few years back, but we also recognise the need for great PMs that might be able to help us out in our projects. If there is any interest, drop us a note at avantedge@pkfmalaysia.com and we will get in touch wth you.

PCI-DSS: Internal Audit Signoffs

April 17, 2019 / / 0 Comments

After going through previously the nightmare of PCI-DSS Certificates, as described with considerable detail in our writeup previously, we are now faced with a new phenomenon called the Internal Audit Signoff, which is further confusing our clients.

OK, first of all, let’s do a brief recap.

How are 3 ways that PCI-DSS can be validated?

Answer :

  1. Full Report of Compliance (RoC) from QSA – Level 1 Service Providers, Level 1 Merchants
  2. Self Assessment Questionnaire (SAQ) signed off by QSA/ISA – Level 2 Merchants, (Maybe) Level 2 Service Providers
  3. Self Assessment Questionnaire (SAQ) signed off only by Merchant/Service provider – Level 3,4 Merchant, (Maybe) Level 2 Service providers

Those are the 3 endgames for PCI. And of course, the end scenario called Failure, or non-Compliance. But that isn’t cool, unless you are the type who is happy with Thanos snapping his fingers being the definite end to all things.

Now we all know item 1) requires the participation of a third party QSA/ISA to signoff on the Report of Compliance and the Attestation of Compliance. ISA here is internal security auditor. We won’t touch it this round, because this requires a whole new library of articles to discuss.

Item 2) likewise requires a third party QSA/ISA to signoff on the Self Assessment Questionnaire and the Attestation of Compliance.

Item 3) is basically, self signed – not a lot of acquirers take this seriously as basically, its anyone signing off anything they feel like. There is no validation, and sometimes, it’s akin to the CxO sticking a finger to the tongue and putting it up in the air and going, “Yeah, that feels ’bout right. Let’s sign off and say we have these controls!”

Let’s talk about item 1 and item 2.

In item 1, it’s a gimme that the QSA needs to go onsite to the locations to do an audit. I have never heard of any QSA signing off on a full RoC without actually going onsite. Maybe when our tech reaches a point where the QSA can be holographically present in a location and see what’s there without being physically there like a Jedi Force Ghost, that the PCI-SSC would accept the signoff. But by then, we could probably just tell PCI-SSC that these aren’t the companies they are looking for, and then there’s no need to do PCI.

Until then – the question is for item 2, for the QSA to signoff the SAQ, must they be onsite or they can provide a remote signoff?

Now if you ask a QSA what is the difference between 1) and 2), they would say, not much – except they don’t have to waste their time writing the tome called the Report of Compliance (ROC) for level 2. Level 2 is basically a judgement made by the QSA based on existing evidences that what is stated in the SAQ is true, or at least as much as they can have reasonable assurance on. The SAQ is not a document written by the QSA, although they can help, but in this case they are validating it. For Level 1, it’s a different story. They have to write the RoC and the work put into that reporting phase is surprisingly a lot. In comparison, it’s probably like reviewing a first term essay paper written by your senior students (SAQ Validation) versus writing the Silmarillion including the index (RoC).

However, for QSAs to conduct their audit and provide a fair opinion on the controls, they will still want to be onsite for option 2), much to the chagrin of many of my customers. Their argument here is: “Hey I am level 2, why must you come onsite??” And again, the crescendo grows that a Level 2 should have less things to worry about than Level 1 – another myth as old as us telling our children not to sleep with wet hair or else they will wake up with a storming headache.

To get to the bottom of this, we got directly from the horse’s mouth (in this case from Mastercard SDP program response: “In this scenario (describing item 2) the QSA has to be onsite. The QSA cannot simply review a RoC or SAQ without being at the location to validate that controls are actually in place.”

To be fair, the above discussion was applied to L2 Merchants (Level 2 Merchants) – those making more than 1 million volume card transactions per annum. Whether the QSA is willing to take the risk and perform an offsite review for a Level 3 or level 4, I wouldn’t know – that’s up to the QSA and the card brands I suppose. But to be absolutely safe, we would advice that all levels should be treated as such – if you need a QSA to signoff, that QSA needs to be onsite to get it done. Or use the Jedi Force Ghost. Both are acceptable to PCI-SSC I am pretty sure.

So, as an illustration, we had a request from a company, requesting us, for their location, to get the QSA to signoff remotely. Because “The Other QSA did it for us and certified us”. The other QSA meaning someone they engaged earlier.

OK – this certification term again. I am sure that did not happen – but many use the word certification for anything: actual RoC, doing the SAQ with QSA, signoff on SAQ by themselves, getting ASV scan etc…those are typical scenarios we see this certification word being thrown.

Digging further, we received a worksheet which was a typical ‘Scope’ document (you know, where they ask what sort of merchant you are, what business, how many locations, devices, whether you store card etc), and the instruction was to fill this up, send it over to the QSA and the QSA will ‘sign off’ their PCI-DSS compliance, all within 2 weeks.

QSA certified within 2 weeks, remotely, and with just the scope document, without validating any controls? No penetration testing or ASV? No Risk assessment? No review of information security policy? How?

We asked for the copy of the official signoff page (Section 3c of the AoC) but instead we got a signoff on a report from QSA stating what was scoped in and what was scoped out of PCI-DSS. A typical scope document. It’s a useful document, but it’s not a document required by the PCI SSC. In fact it doesn’t serve any purpose other than to simply state what is in scope for PCI-DSS based on the scope questionnaire (not the SAQ) provided by the QSA.

I am 100% sure the QSA meant well by this, but the problem was, there are interpretation issues. We cannot expect clients to right off the bat understand PCI-DSS and all it’s seemingly malarkey documents – the AoC, the RoC, the 9 different SAQs, the ASV scans, the partridge in the pear tree etc. So when we asked for a SAQ signed off by QSA, of course, clients will fall back to any document being signed off by QSAs. That’s why we are not big fans of the practice where clients are provided by ASV certificates just because they passed their ASV scans. They all think they are PCI certified because they have a QSA signed off document which is the ASV ‘certificate’! And the same here goes, this is simply a scope review document – almost like an internal audit report, that does not make a company PCI compliant. In fact, it is just confirming that the company MUST be PCI compliant according to the scope set.

So the moral of this story is: Not all QSA-signed off documents are valid documents for PCI-DSS. ASV scans, while valid, doesn’t make you PCI compliant. It’s only a small percentage of what you must do. Internal Audits or scope reviews like the one we saw, even signed off by the QSA, are not valid PCI-DSS documents. They do not make you PCI compliant. As PCI has explicitly stated before, the only valid PCI-SSC documentation are the AoC, SAQ, RoC and ASV scan reports (not certificates, with flowery borders and impressive cursive fonts in gold). Anything else are supplementary materials used to support the compliance, not to validate it.

For more clarity on PCI, drop us an email at pcidss@pkfmalaysia.com. We will try to sort any issues you have, and yes, we are the company you are looking for.
