Take your PCI compliance to the next level
Think about how many times each day you pull a credit or debit card out of your wallet to pay for gas, groceries, a cup of coffee, or a new pair of shoes.
The article explains that credit and debit card data is ubiquitous across company networks and that any organization processing card transactions is at risk of data breaches, with real-world consequences including financial loss and reputational damage. It emphasizes that PCI compliance is the essential baseline for protecting payment card data but may not cover all security gaps, so organizations must perform network vulnerability gap analyses and maintain robust logging, monitoring, and testing. The article highlights practical controls—tracking access, creating PCI zones, maintaining DNS/DHCP logs, encrypting stored logs, and using solutions like BlueCat IPAM and BlueCat DNS Security to increase visibility and detect inappropriate behavior before breaches escalate.
Why is PCI compliance described as a baseline and not sufficient to guarantee protection from cardholder data breaches?
The article states PCI compliance provides specific regulations and best practices and should be a top priority, but it does not cover every potential security issue. Organizations can still have vulnerability gaps outside of PCI’s scope—such as insufficient DNS/DHCP logging, unencrypted stored logs, lack of detailed audit timestamps, or absence of processes to review logs for abnormal behavior—that attackers can exploit. Therefore, businesses must perform network gap analyses, implement additional controls, and continuously test and monitor systems to reduce risks beyond PCI requirements.
What specific logging and monitoring practices does the article recommend for protecting payment card data?
The article recommends tracking and monitoring all access to network resources connected to cardholder data, maintaining DNS and DHCP logs as part of the PCI program, and ensuring logs provide sufficient audit details like time and date stamps. It also advises determining how and where logs are stored, ensuring stored DNS/DHCP data is encrypted, and establishing a process to review security logs to detect abnormal patterns or behaviors. Regular testing, internal PCI data audits, and network monitoring are also highlighted as important practices.
How can BlueCat products help an organization improve protection of customer payment card data according to the article?
According to the article, BlueCat offers solutions to bolster visibility and threat protection beyond PCI baselines. BlueCat IPAM provides complete visibility and control over IP address management data, tracking device movement, network resources, and discovering unknown devices on the network. BlueCat DNS Security gives visibility into every device to help identify inappropriate behavior early. Together these solutions help organizations locate vulnerability gaps, monitor DNS/DHCP activity, and detect anomalous behavior that could indicate an impending data breach.
Think about how many times each day you pull a credit or debit card out of your wallet to pay for gas, groceries, a cup of coffee, or a new pair of shoes. Now, think about how many times each week you make online purchases. If you’re a frequent shopper on a particular website, you may have saved your credit card information on the website.
These behaviours are pretty common and illustrate the point that credit card data is everywhere … on company networks anywhere around the world … right this very minute. And hackers are working diligently to get their hands on that data.
Over the past few years there have been several news stories about major retailer data breaches, which became a huge wake-up call for company executives. The companies who were targeted had to spend millions of dollars replacing customers’ store credit cards. For some, stock prices took a nosedive and the company also had to deal with the very public fallout from both a PR perspective, and even more importantly, the loss of customer trust.
You may think that your company isn’t at risk of a credit card data breach for a variety of reasons, but the reality is, any company that uses credit or debit card transactions is at risk for a data security breach.
What steps can your company take to protect your customer payment card data?
Don’t assume that because your company is PCI compliant, you’re safe from a databreach.
PCI compliance is the baseline for payment card data protection; no matter the size of your organization, it should be a top priority to avoid the costly liabilities and reputational damages associated with a data breach.
First, ensure that your organization is compliant with payment card industry (PCI) standards for data security. The PCI Security Standards Council has outlined very specific regulations and best practices to help businesses store, process, transmit, and protect consumer credit card data. Large organizations may have an entire department devoted to PCI compliance with regular data audits, network monitoring and testing programs, IT security policies, and vulnerability plans. Smaller organizations may not have a team of people specifically overseeing PCI compliance, but it should still be a top priority to avoid damaging and costly liabilities.
Here are a few questions to think about as you determine if your company is PCI compliant[1]:
- Are you tracking and monitoring all access to your network resources that are connected to cardholder data?
- Have you created a PCI zone?
- Have you identified and implemented specific controls to ensure the security of your systems?
- Do you regularly test your network security systems?
- Do you have a plan to conduct internal PCI data audits?
Second, don’t assume that because your company is PCI compliant, you’re safe from a data breach. PCI compliance should be your baseline for credit card data protection, but it doesn’t cover all potential security issues. To truly become secure, you should examine your network to find vulnerability gaps, and you should take steps to fill any gaps to make sure it’s as secure as possible. These questions are often overlooked when performing a data security gap analysis:
- Are you maintaining DNS and DHCP logs as part of your PCI compliance program?
- Do the logs provide sufficient audit details, such as time and date stamps?
- How and where are you storing these logs?
- Is your stored DNS and DHCP data encrypted?
- Do you have a process for reviewing the security logs to look for abnormal patterns or behaviors?
If you need help ensuring that your network is PCI compliant or if you want to boost your network security beyond the regulations of PCI compliance, BlueCat can help you. We offer robust threat protection solutions, such as:
BlueCat IPAM, which gives you complete visibility and control over your IP address management data by tracking the movement of devices and network resources, as well as the discovery of unknown devices.
BlueCat DNS Security™, which provides visibility into every device on your network to help spot inappropriate behavior before it becomes a major data breach.
PCI compliance is the baseline for payment card data protection; no matter the size of your organization, it should be a top priority to avoid the costly liabilities and reputational damages associated with a data breach. Moreover, your company should continuously strive to find and fill vulnerability gaps in order to keep your network secure.
