The OSSEC PCI DSS and HIDS framework offers a solid foundation for Payment Card Industry Data Security Standard (PCI DSS) compliance, featuring intrusion detection and prevention, log analysis and monitoring, file integrity monitoring (FIM), and controls to maintain secure audit trails.

However, revising and writing new OSSEC PCI rules to meet new PCI DSS version 4.0 requirements—and extending OSSEC PCI DSS compliance to additional operating systems and cloud environments—can be a pain. Benchmarking and reporting PCI compliance without an integrated SIEM and dashboard GUI capability, or technical assistance, represents another challenge.

Enhance OSSEC for PCI DSS 4.0 Compliance

Let Atomicorp take the pain out of PCI. Our OSSEC PCI DSS solutions can be used to meet more than 100 of PCI required controls that can be addressed by software. Some of these requirements and controls include: 

• The implementation and maintenance of a firewall to protect cardholder data, with the inclusion, but not limited to, inbound and outbound traffic restrictions, the establishment of a DMZ, anti-spoofing measures, password hardening, and air-gapping techniques to prohibit direct public access between the Internet and CDE system components.
• The protection of stored cardholder data, which requires PAN files to be rendered unreadable anywhere they are stored. Atomic OSSEC can automatically find cardholder data that is not properly protected in your enterprise. 
• The implementation and management of antivirus and antimalware programs on all systems, including malware removal. AV anti-tampering controls are also required so that AV cannot be removed without authorization.
• The development and maintenance of secure systems, applications, and the broader “software” category (the latter added in PCI DSS v.4). This entails the implementation of web application firewall (WAF) and web application security and website protections, ranging from XXS and CSRF website security controls to brute force and code injection protection.
• The restriction of cardholder data and CDE access to “need to know” and “least privilege” basis, as well as default deny-all settings, bringing in foundational elements of zero trust architecture.
• The assignment of a unique ID for each person with computer access. This should be governed by MFA, changing and hardening passwords, and timely user account removal and user account management.
• The implementation of automated audit trails. This means your log should capture every event and must include user ID, type of event, date and time, be saved for at least one year, and meet additional criteria. This auditing system must itself be protected from unauthorized changes.
• The regular testing of systems and processes. To be PCI compliant, an organization is required to perform internal and external vulnerability scans, and assess and address potential flaws and systems through penetration training.

There’s more to OSSEC PCI DSS compliance than the aforementioned, and Atomicorp will be happy to help you with any issues related to PCI DSS 3.2.1 and PCI DSS 4.0.

FIM is not only a crucial capability in PCI DSS compliance, but one of the more important security features required by organizations and agencies safeguarding private and sensitive data and data environments. Atomic OSSEC, a commercial OSSEC version providing OSSEC HIDS and OSSEC FIM, enables security and compliance users to see in real time what changed in an environment. Real-time OSSEC FIM enables user organizations to assess what the change means when it happens, with help from integrated threat intelligence and preconfigured yet versatile automated rules. The extended detection and response (XDR) rules and Machine Learning engine in Atomic OSSEC enables your OSSEC HIDS to be more active and respond more rapidly and analytically, while reducing false positives and negatives. Make OSSEC PCI DSS and OSSEC FIM easier with Atomic OSSEC software and support.
