Consequences & Risk Exposure for Non-Compliance with PCI DSS for the Banking Sector

Every day millions of people around the globe fall prey to cybercrimes. What makes it alarming is that majority of the data breach/theft is related to debit and credit cards. For these reasons, the PCI DSS standards were set in 2006 to strengthen information security and secure cardholder data. PCI DSS is a compliance requirement for all organizations and financial institutions including banks that deal with card transactions. As per the set guidelines, banks and other financial institutes are expected to have in place comprehensive internal controls, and security frameworks to safeguard sensitive data. Financial institutions heavily deal with millions of transactions daily, which is why it is an incredibly challenging task for them to secure transactions and cardholder data. For the amount of risk they are exposed to, the financial institutes are the most heavily regulated industry in the U.S. and around the world.

In this article today we have discussed how PCI DSS Impacts the banking sector and the risks they are exposed to for non-compliance.

PCI DSS Compliance in a Glance

Payment Card Industry Data Security Standard is the set of security standards administered by the PCI Security Standards Council and established by the top 5 credit card brands namely the American Express, Discover Financial Services, JCB International, MasterCard Worldwide, and Visa Inc. The Compliance Standard applies to –

• Any organization or institute that deals (store, process, transmit) with credit cards including service providers.
• Any organisation (service provider) whose functioning can affect the security of the Card Data Environment of another organization (Client of service provider)

The scope of compliance typically covers data security, security framework policies and procedures, network architecture, and software design. Financial institutions, including issuing banks, (banks that offer credit cards to customers) and acquiring banks (financial institutions that hold merchants’ bank accounts, receive payments through the card processors, and deposit funds on behalf of the merchants), merchants, and service providers who process, store, transact, or enter into a contract with the five-card brands are expected to be PCI DSS Compliant.

Impact of PCI DSS Standard on the Banking Sector

PCI DSS is a set of security standards that banks need to follow diligently to stay compliant. For millions of transactions that they undertake daily and the risk to which they are exposed, requires them to have in place strong security measures to safeguard Cardholder data. Given below are some PCI DSS Standard Requirements that banks are expected to follow and security tests they need to perform to ensure no compromise of the cardholder data environment.

• Test the defense systems in place to ensure network, end-point, and web applications are secure.
• Frequently commissioning a controlled data breach attempt against the bank network to secure networks (Penetration Testing or even a Red Team assessment).
• Perform security tests to detect known vulnerabilities like SQL injection, OS command injection, Cross-site scripting, broken authentication, etc.
• Test networks and check for the presence of authorized and unauthorized wireless access points every quarter.
• Perform Penetration Test on the cardholder environment (CDE) and systems and networks connected to it at least once a year or after a signification change has been made to the application.
• Conduct a VAPT test to identify all possible threats and exploit them to penetrate the system at the application and network level.
• Issues identified should be corrected and re-tested until the time systems and networks are clean and have strong defense systems in place against malicious activities.
• Conduct Internal audits as per the PCI DSS requirements atleast once a year or after any major change to processes or systems.
• Internal awareness training for the employees atleast once a year.

While it extremely challenging to meet the testing requirements of PCI DSS, performing the test and securing systems and networks is mandatory for Banks and other financial institutions. Failure to comply with the bank will have to face severe repercussions in terms of huge penalties, and loss of trust and credibility. We have listed below some serious repercussions and risks banks may be exposed to for non-compliance with PCI DSS.

Consequences and Risk Exposure to Non-Compliance with PCI DSS for Banking Sector

The risk of merchants suffering a data breach has far greater, implications and consequences, resulting in monetary penalties and often, irreparable damage to brand reputation.

Data theft & Security Breach-

Being non-compliant to the PCI DSS Standards simply means the bank may not have the necessary security measures in place to protect data. Having no strong defense systems and security built around the network and systems will lead to a security breach and data theft. This could further have huge financial implications on the institute, leading to huge losses.

Hefty Penalties

Non-compliance to PCI DSS can result in huge penalties ranging from $5,000 to $100,000 per month by the credit card companies. The penalties levied shall depend on the volume of transactions, and the degree of non-compliance. Further, the penalties levied shall be based on the discretion of the payment brand and the brand may decide to levy penalty based on per record that has been breached Moreover, the fines get reassessed monthly and may raise over time until the merchant achieves compliance. However, fines that the bank incurs can be passed to the merchant via high transaction fees or service charges if in case the merchant is found to be non-compliant. This will further strain or affect the relationship between the bank and the company.

 Compensation costs for non-compliance

A huge amount of compensation costs would involve in case of non-compliance to PCI DSS Standards.  The banks or merchants will have to probably compensate the clients with credit card monitoring, identity theft insurance, or in any other form of compensation.

Tarnished Reputation due to non-compliance

Security breaches and data theft shall not just have financial implications but will also cause irreversible damage to the reputation of your brand. Once your security is compromised, it will be very difficult to regain their trust in your bank. The image and reputation of your bank will be at stake and greatly tarnished if found non-compliant and face a security breach.

Revenue loss

Once there is a blot on reputation, it will significantly impact the business revenue and sales. There is a huge possibility of the bank facing loss due to an incident of a breach. Infringement can lead to loss of consumers, followed by loss of revenue. The financial implications are far more significant than the amount of money it would probably take to ensure compliance with PCI DSS.

Direct Intervention of Regulatory Bodies-

Non-compliance to PCI DSS followed by a security breach could call for the direct intervention of Regulatory Bodies and involve frequent Federal Audits. This would further involve imposing strict regulations and penalties. Consequences like this could severely impair the banking business.

Conclusion

The bottom line is that no matter how strong your defense is and the number of assessments you conduct, it just needs one slip for the breach to happen. So, no system is totally impenetrable, but at the end of the day, incase of breach, you need to present your bank in a way that it has followed all the compliance requirements and did its best to secure the systems to the best of its knowledge and ability.This is where the banks need to work on by conducting due dellligence as detailed in the standard and summarized above in the article.

Moreover, we belive complying with the security standards is extremely important not just for the banking business, but also for the safety of their clients. While the standard requirements and testing process may seem to be rigorous, but the consequences of non-compliance can be destructive for the banking business. Banks in general have their take on the set standards. Depending on the risk levels (which are often high in the banking sector) and exposures, banks generally balance between the cost, security, and functionality, while investing in an effective security control framework.
