1. Monitor all access to network resources and cardholder data, always keeping PCI DSS Requirement 10 in mind!<\/strong> If you’re wondering whether to log a network vector or any component of your point of sale (POS) system, it’s better not to log everything.<\/p>\n\n\n\nWhether your networks are on-premises, in the cloud, or hybrid, there are log analysis tools and SIEM systems with which you can route all of your logs to help make comprehensive logging manageable. Absolutely all actions on your network must be recorded and attributable to a specific user or process.<\/p>\n\n\n\n
2. Protect access to your logs.<\/strong> Only administrators can view or make any changes to your logs and audit trails. Everything an administrator does on your POS systems and other networks should also be logged and attributable to them. If any non-admin user can view or change your logs, your POS data integrity will be unnecessarily at risk.<\/p>\n\n\n\n3. Every user on your network must have a unique username.<\/strong> Do not allow multiple people on your network to have a user account or a specific username. If any action someone takes on your network cannot be attributed to a specific person, PCI DSS compliance checks will likely fail.<\/p>\n\n\n\n4. Review your logs regularly.<\/strong> If you do not review your logs regularly, you cannot be sure of your diary recording’s integrity and reliability. This requirement can be met by making a specially qualified person manually review your logs. However, it will probably be more useful to use automated tools for log analysis and event tracking. Additionally, the company would be better able to prevent cyber-attacks until they cause harm to your POS networks and your entire retail operation.<\/p>\n\n\n\n5. Timing is everything and very important.<\/strong> You should make sure that the clock clocks that direct your systems and applications are set correctly. Timestamps in your logs will be made according to the time specified in your apps and devices. Correct system configuration can make automatic adjustments for events such as when daylight saving time starts and ends. Whether a customer makes a transaction or an unauthorized user attempts to access your sensitive POS data, you need to know exactly when it happens in order to keep logs that meet PCI DSS compliance requirements.<\/p>\n\n\n\n6. Keep your logs for at least a year.<\/strong> You can keep your logs even longer if you want, but at least one year is an absolute log retention period for PCI DSS compliance. When data is generated from your automated daily analysis tools, retain them for at least a year as well.<\/p>\n\n\n\n7. Note what critical events need to be logged. <\/strong>Critical events are as follows, and you should log all of these events:<\/p>\n\n\n\n\nAnytime any user accesses cardholder data,<\/li>\n\n\n\n All root or admin user actions,<\/li>\n\n\n\n Access to audit trails,<\/li>\n\n\n\n Invalid logical access attempts,<\/li>\n\n\n\n Any use and change in authentication mechanisms,<\/li>\n\n\n\n Deleting, pausing, or stopping logging,<\/li>\n\n\n\n Creation and deletion of system-level objects.<\/li>\n<\/ul>\n\n\n\n8. Make sure all your logs contain the following information:<\/strong><\/p>\n\n\n\nEvent type, date and time, success or failure indicator, source of the event and affected data, identity or name of the system component or resource.<\/p>\n\n\n\n
Summary<\/strong><\/h2>\n\n\n\nAchieving PCI DSS compliance will be much easier if you follow the tips above. At the same time, your organization will be more likely to undergo compliance audits, and it will be much easier to secure your sensitive financial data.<\/p>\n\n\n\n
Having an audit trail is an essential part of the Payment Card Industry Data Security Standard (PCI DSS).<\/p>\n\n\n\n
Audit logs, log management, logging are all essential parts of PCI DSS requirement 10.7. PCI DSS requirements require audit logs to be retained for a minimum of one year. Ninety days of PCI audit logs should also be available for immediate analysis.<\/p>\n\n\n\n
A compromise can take several months to be realized, so there is a one-year requirement for PCI compliance. Log data is useful in active event response agreements, so you should have ninety days of log data at hand. Log data is useful when an organization is examining logs in real-time. The log files contain information about security events, network resources, event logs, system components, and suspicious activities.<\/p>\n\n\n\n
Protection of cardholder data is one of the essential requirements of PCI DSS compliance. A mature information security program focusing on PCI DSS, complete with security information and incident management system (SIEM), integrates multiple cybersecurity disciplines such as file integrity monitoring, intrusion detection systems, user activity, Syslog collection data breach detection. It protects cardholder data by having a security policy.<\/p>\n\n\n\n
SIEM uses log data from log servers and provides log analysis to create an audit trail history. A suitable SIEM has alerts configured to help information security professionals locate operating systems and user account compromises that could compromise credit card and card data.<\/p>\n","protected":false},"excerpt":{"rendered":"
