4 immediate actions to take after a PCI data breach

by | Apr 27, 2023 | Security

Data breaches are a reality that can occur regardless of your level of preparedness or PCI compliance. Surprisingly, almost 1,850,832 data records are lost or stolen during the average 8-hour workday. Instead of thinking about if a data breach will happen, it is important to plan for when.

In the aftermath of a PCI data breach, every second counts – and implementing the right damage control measures is crucial to mitigate further risks and safeguard your organization’s reputation. In this article, we explore the top 4 immediate actions you need to take following a PCI data breach, ensuring the most effective response to minimize the impact and protect your customers’ trust.

What are the consequences of a PCI data breach?

A PCI data breach occurs when unauthorized access is gained to sensitive payment card information, such as cardholder names, card numbers, expiration dates, and security codes. Payment Card Industry Data Security Standards (PCI DSS) are designed to protect this data, but even the most robust security measures can sometimes fail. The consequences of a breach can be far-reaching, with significant financial, legal, and reputational damage on the line.

The financial impact of a PCI data breach can be staggering. Organizations may face regulatory fines, legal costs, and compensation payments to affected customers – not to mention the potential loss of future revenue due to damaged customer relationships. In addition, the cost of investigating and remediating the breach can quickly add up. Beyond the direct financial implications, organizations must also grapple with the potential legal fallout, as they may be held liable for any unauthorized transactions made using the compromised data.

The reputational damage caused by a PCI data breach can be equally devastating. Customers place a high value on the security and privacy of their personal information, and any breach of this trust can lead to a loss of customer confidence in the organization. This can result in a decrease in customer loyalty, negative word-of-mouth, and ultimately, lost business. In today’s highly connected world, news of a data breach can spread quickly, and organizations must act swiftly to mitigate the fallout and restore their reputation.

Immediate actions to take after a PCI data breach

Implement an incident response plan

When a breach occurs, having effective incident management protocols in place is a must, and is in fact a PCI DSS requirement. An incident management plan allows enterprises to respond immediately to data breaches and should be well-planned and routinely tested to ensure all parties understand their roles and the process does not have any gaps which could be exploited.

Contain data exposure

When a breach occurs, limiting data exposure while maintaining the evidence of the breach is essential. It is critical that computers, devices, servers, or network equipment are not turned off, as this can cause digital evidence to be lost that is needed to rectify the breach and address any issues that can prevent future attacks. Losing this evidence also makes it much more difficult to investigate what happened. Instead, ensure any modems, routers or equipment that has access to customer information is disconnected from the internet and network.

Identify the scope of the breach

To prevent further damage and assess the extent of the data at risk, it is crucial to pinpoint the origin of the breach. This will give you a better idea of how long the information was exposed for. After that, it is essential to conduct an impact analysis to determine the full extent of the compromised data, including the quantity and type of information that may have been impacted, such as:

This is also a good time to determine the duration of the exposure period, keeping in mind that it may exceed the initial estimate. Credit card providers and financial institutions often issue alerts regarding possible security breaches, but the accuracy of the timeframe provided may be limited.

Enacting notification plan

It is important to be ready to quickly notify relevant individuals or organizations. To achieve this, it is crucial to have a plan in place and to regularly confirm the up-to-date and precise contact details for each party involved. The plan should cover payment card brands, acquirers (merchant banks), and any other entities that may require notification, whether due to contractual obligations or legal requirements.

Is a PCI forensic investigation required?

Whether you will need to complete an independent investigation through a PCI forensic investigator will depend on the type of information that was breached and how it was compromised. A PCI investigation must be completed within a specific timeframe, and the PFI’s report must abide by certain guidelines.
