Regularly reviewing these logs allows businesses to recognize patterns of suspicious activity. A sudden spike in login attempts from unknown sources, for example, could indicate an attempted cyberattack. If a breach occurs, access logs provide critical forensic evidence to determine how the attack happened and what data was compromised.
Best Practices for Managing Access Logs
To effectively manage access logs, businesses must store them securely and prevent unauthorized alterations. Automated monitoring tools can help track real-time activity and send alerts if unusual behavior is detected. Reviewing logs frequently is also necessary to ensure compliance with PCI DSS requirements. Businesses should retain these records for the required period, allowing security teams to investigate past incidents if necessary.
By properly maintaining access logs, businesses can strengthen their overall data security strategy, protect cardholder data, and demonstrate PCI DSS compliance when required.
