PCI DSS compliance challenges for the E-commerce Sector

The Internet is the fastest growing retail sector, and it is therefore not surprising that many merchants are turning to this sales channel to maximise sales potential. Also barriers to entry are far lower, allowing many start-up and fledgling businesses an opportunity to commence trading with minimal capital outlay –however if systems are not fully secure, they could find themselves vulnerable to remote attacks from anywhere in the world. With a wider range of goods available, there has been a significant increase in the number of customers using their payment card online, with more card data being transmitted and stored via the Internet.

It is not surprising therefore, that the E-commerce sector faces numerous challenges in order to protect itself from the growing threats from malicious individuals and organised crime looking to identify and exploit weaknesses in the payment process. The 6 leading worldwide major payment card brands established the Payment Card Industry Data Security Standards (PCI DSS) as a standard to protect cardholder data from such attacks.

The PCI DSS contain 12 requirements that are grouped within 6 core principles. If an organisation processes, stores or transmits cardholder data they will be in scope for PCI DSS. All E-commerce systems will need to be considered. In many circumstances, business owners in this industry do not have the resources or the technical knowledge to help reduce the risk of a data breach. Nevertheless, even large E-commerce merchants with skilled personnel also suffer breaches, one merchant was responsible for the loss of over 50 million card numbers.



‘If the initial scope is not sufficiently detailed, it could result in a breach of cardholder data’

PCI DSS compliance in practice
The first part of any PCI DSS compliance assessment is scoping. Without a thorough analysis of cardholder data flows (physical or electronic), a PCI project could miss vital areas, for example legacy systems, or over-engineer systems upgrades because the process wasn’t fully understood. The following are some critical areas that are typical for E-commerce environments, but could be overlooked:




  • Log Files: Many E-commerce systems conduct online authorisations, with the full PAN being stored once the transaction has been completed. PCI DSS requires that PAN must be made unreadable (truncation, hashing, tokenised or by using strong encryption). Places that potentially could store this type of data, but are often overlooked include transaction files, debug files, back-up files, history files or application logs.


  • Software Development: Companies who have developed their own web applications should
    employ a developer who has experience in secure coding practices. It is essential that the coding is secure, as a line of insecure code could facilitate an entry point for a malicious user. An often overlooked area is the use of third party tools/libraries/scripts. Vulnerabilities in third party code may open a backdoor to E-commerce systems to drop malicious files or provide an entry point for an unauthorised user to steal database information containing cardholder data and/or other sensitive information.


  • Off-the-shelf packages: Organisations using third party payment applications are reliant on the security of these applications. Smaller retailers may purchase E-commerce systems which are in fact open source websites with minor modifications. These packages are often attacked as the underlying source code is publicly available and provides information on the security mechanism (or lack of) used. This may open holes within the E-commerce system to plant viruses, trojans or even worse, provide a malicious user with an opportunity to directly query databases that may contain a collection of cardholder and other sensitive customer information.


  • Third Parties: A merchant is responsible for any agent they engage on their behalf. If an organisation relies on a third party to collect cardholder data, the third party must undergo a PCI DSS assessment, and if the third party is not PCI DSS compliant then the merchant is not compliant either.


  • Post-authorisation: Storing sensitive authentication data (CVV/CV2) post-authorisation is strictly prohibited by PCI DSS. Indirectly Connected Devices: Any machines not involved in cardholder data processes but are logically connected to devices that do process, store or transmit cardholder data will be in scope. situation and their business. Although PCI DSS seems a long and daunting process with good planning and a clear road map, supported by an experienced and pragmatic QSA partner, compliance can be achieved. This will also put the business in a stronger position as there will be a greater understanding of how
    systems work within the organisation, and also the identified potential risk areas. Business should also consider that the financial and reputational costs of a data breach could be far higher than the implementation of a PCI project.


‘PCI DSS is achievable with guidance and an effective roadmap’



Achieving PCI DSS
Some companies may first conduct a gap analysis and then remediate the problems. Sysnet recommends an initial scoping exercise is undertaken - this will review all systems, which will shape the extent of the PCI DSS project. It will also highlight areas of current risk that potentially could be removed with replacement systems or secure enhancements.

A scoping exercise offers options to manage to the size of the project by offering ‘as is’ and ‘what if’ scenarios to clearly demonstrate how change to the process impacts the scope. The organisation then has the opportunity to choose the option they feel is most appropriate to their

‘A commitment to protecting customer’s cardholder data 24/7 365 days a year’

Maintaining PCI DSS compliance Once the people, processes and technology are in place, re-assessment should become far easier. Many businesses use PCI DSS as an opportunity to introduce new hardware and operating systems, and merge disparate business processes – it is therefore essential that a full scoping review is undertaken
prior to engaging in any major project development. A commitment to PCI DSS is a commitment to protecting
customer’s cardholder data 24/7, 365 days a year.

Data Breaches – Compulsory Disclosure?

EU Justice Minister Viviane Reding, has recently announced that she is formulating a policy that will mandate any business trading in the EU or who targets EU residents, to notify their customers, and the regulatory authorities, if they suffer a data breach. The intention being to ensure that all businesses handling sensitive data take their obligations seriously.


This action follows the recent spate of attacks on some high profile organisations, where millions of personal data records were subject to data hacks.


Following the introduction of the EU e-privacy directive on 26th May 2011, Telecoms, and Internet Service Providers are already subject to mandatory data breach disclosure, and the Minister is now seeking to widen these powers to include all sectors.


The legislation has the power to impose penalties and legal sanctions for any infringement and it is expected that these strong ’incentives‘, will encourage businesses to conduct serious risk assessments regarding their storage of sensitive personal data, and implement appropriate security measures to protect the confidentially and integrity of this information.


It should also be noted that the UK Information Commissioner has regulatory powers to investigate and penalise in cases of deliberate and persistent misconduct.


With all of the increasing media and regulatory interest in data security, how does a business go about protecting its’ key assets, particularly customer databases and avoid a data breach?

How can Sysnet Global Solutions help?
Sysnet offers a Security Assessment service, which provides a unique and flexible approach encompassing Incident Response, Audit, Computer Forensics and Penetration testing.


The assessment will be tailored to the individual needs of the business, and can include reviews of encryption, wireless networking, portable device security, contingency plans, security awareness, system configuration and premises vulnerabilities.

If a business takes card payments, they will fall under the requirements of the Payments Card Industry – Data Security Standards (PCI-DSS) – However the Sysnet Security Assessment service goes into far more detail, so that the customer can feel confident that they are in control of their security position.


Additionally Sysnet offer an on-demand, computer incident response service, whereby in the event of an incident, Sysnet can be on call ready to provide advice and visit the affected site to help contain the incident, offer guidance and if required, conduct a forensic investigation. This service is pre-arranged and also includes an initial visit to the site to help assist in highlighting security vulnerabilities, and offering remediation planning to overcome these weaknesses.


Whilst no business can be wholly safe from a data incident, by following the guidance given by the Sysnet CFS team, businesses can reduce their exposure to receiving such an attack, but also will be in a far better position to respond in a positive and speedy manner, to ensure continuance of trading and minimisation of brand and reputational damage.


Another key area is the storage of unencrypted card data - under PCI-DSS all card data should be securely deleted from computer systems, or if deemed necessary for operational requirements, then the information needs to be stored in a suitable encrypted format. In all too many cases, when a forensic investigation is undertaken following a data breach, card information is located in clear text.


This can be due to a number of circumstances, forgotten databases, legacy systems deemed out of scope for PCI accreditation, or back-up files converting encrypted information into readable format. Whatever the reason, storing unencrypted data will heighten the risk, and invalidate any PCI compliance certification.

To mitigate operating with such vulnerability, Sysnet are able to offer their Cardholder Data Discovery Service, which can scan server, PCs, and storage media for unencrypted card numbers. Once the scan has been completed, and if any residual information has been identified, we can safely erase the data, help prevent it from being stored or if preferred, give guidance as to how the records can be held securely to conform to the PCI-DSS.


Sysnet bring the pragmatic mindset of a forensic investigator together with knowledge of real world hacking to give you the edge in security management.

Common Cyber Crimes facing the Payments Industry

There is little doubt that an Account Data Compromise (ADC) would be detrimental to the operational effectiveness of any business. However, to organised criminal groups it can be an easy way in which to generate funds for criminal gain. In the 21st century, it can be easier for a criminal gang to commit cyber crimes, such as raiding the credit card details of a poorly maintained website, than to raid a high street bank.

The favoured methodology of website hackers is to exploit poorly written and unsecured websites and then seek to locate the credit card information held within. By focusing on weaker websites in this way, and ensuring that the total level of card fraud is not too high, many of the hackers simply take the ‘low hanging fruit’ and go unnoticed until it is too late.

Often exploiting the same common vulnerability across multiple different hosts, for example an authentication weakness in a popular shopping cart, allows the hacker to simply trawl the Internet for those websites that use that shopping cart to exploit and collect the reward. No organisation wants to fall foul to cyber crimes and therefore in order for them to protect themselves against a potential information security breach, certain steps should be taken to reduce susceptibility to the most common types of breaches.

Legislation
The unlawful access to a system that is used by a merchant is on the whole in breach of section 1 of the Computer Misuse act and in the real world, stealing of cardholder data is more than likely to be associated with the stealing of PII (Personally Identifiable Information). Therefore, once a data breach has occurred, it can easily escalate from an exercise where the card brands are requesting their card numbers to be returned, to the local law enforcement agency mounting a personal data loss investigation.

Cardholder data breaches, that are the result of cyber crimes, are increasing raising interest within the various law enforcement and data protection agencies around the EU. Although currently each member state takes a different view on how to deal with the consequences of cyber crimes, growing public awareness on the issue could see law enforcement take a heavier, more legal based role in the near future.

Protecting Your Organisation
There are no hard and fast rules to ensure that your website is safe and secure from the persistent threat of cyber crimes. However, there are some actions that organisations can take to help avoid large fines for the misuse and loss of cardholder data. Below are 10 helpful tips for organisations seeking to become more proactive;


  1. Get PCI DSS compliant. Look at your merchant agreement with your acquirer, it will state that you need to be PCI DSS compliant;

  2. Plan, Plan, Plan – you don’t know when the event might happen but an incident response plan and regular testing of this plan will pay dividends in the event of a breach;

  3. Suppliers - know who your suppliers are and also what cardholder data they may or may not be processing on your behalf. They will need to be PCI DSS compliant and could easily be your weak point in the protection of cardholder data;

  4. PFI Company – if there is a breach, one may be turning up at your door and asking questions that you might not immediately know the answer to. Pre-appointing a PFI and talking to them about what happens in a breach will iron out any potential problems;

  5. PR Response - should the worst happen and your businesses’ reputation is on the line, have a pre-planned public response; a response prepared beforehand is far better than a response drafted in the heat of the moment;

  6. Policy – one of the easiest ways to mitigate the risk that a breach represents is to ensure that policies and procedures are robust enough to reduce the chance of a cardholder breach and also have the flexibility to respond if a breach occurs;

  7. Data Protection – the legal and compliance authorities are becoming more interested in ensuring that the cardholder data that merchants process and the personal information they obtain is kept within the realms of the merchant, and does not get into the hands of the hackers. Whilst the card brands could fine an organisation for the miss-use and/or loss of cardholder data, the data protection authorities can also stop a merchant processing cardholder data;

  8. Acquisition of evidence – should an external party be required to investigate a breach, a lot of time, energy and effort can be saved by allowing the external investigative party to investigate and acquire the data. The more that the data is tampered with before a forensic investigation is carried out, the less information can be found out about what actually happened;

  9. Check your liabilities – ensure that you have the correct contracts; it may be that your 3rd party has provided you with a ‘managed’ firewall but what does that mean? You may only find out when a hacker has already taken your customer’s cardholder information away;

  10. Don’t Panic –If the worst should happen, act with a clear head and don’t make rushed decisions that could affect the outcome at a later stage.

The UK Data Protection Act (1998) requires any organisations that receives, transmits, stores or processes personal information to comply with the eight basic principles contained in Schedule 1 of the Act.


The essence of the eight principles can be summarised as follows:



  • Personal data shall be processed fairly and lawfully

  • Personal data shall be obtained only for lawful purposes

  • Personal data shall be adequate, relevant and not excessive

  • Personal data shall be accurate and kept up to date

  • Personal data shall not be kept longer than necessary

  • Personal data shall be processed in accordance with the rights of data subjects under this Act

  • Appropriate technical and organisational measures shall be taken against unauthorised or unlawful processing

  • Personal data shall not be transferred to a country or territory outside the EU except in specific instances where equivalency of safe-harbour applies

Compliance with the Data Protection Act is a legal requirement for all organisations operating in the United Kingdom which collect, store or process personally identifiable information. Ensuring ongoing compliance with the Act is therefore an essential management activity for any company or organisation which engages is the abovementioned activities.


In addition to potential penalties that may be imposed by the courts or the Information Commissioner’s Office, most modern organisations are reliant on their brand reputation to attract and retain customers and partners in the private sector or to achieve their organsational or statutory goals in the public sector.


As such a breach of data privacy could have far wider consequences than any sanction imposed by the Information Commissioner or any other regulatory body and could compromise a key commercial relationship or prejudice your organisation’s ability to win and retain customers.


Achieving compliance with the Data Protection Act should begin with the selection of an expert third party advisor and is achievable through a regime of analysis and assessment, training and awareness initiatives, organsational support and policy implementation all of which need to be underpinned by appropriate technological architectural and infrastructure investments.


In conjunction with the expert advisor, the next step will be assess your organisation against the eight principles of Schedule One of the Act and determine a remediation plan that will close off any shortcomings identified in the most pragmatic and cost efficient manner.


This is usually achieved by a process involving the following steps:



  1. Scoping of private data environment

  2. Gap analysis and assessment of current level of compliance

  3. Remediation phase to address identified gaps

  4. Re-assessment and issue of Report on Compliance

The expert advisor will also recommend how best to deal with subject data requests by data subjects whose personal data your organisation controls.
