Audit log management is a critical security pillar for any business owner looking to safeguard their assets, ensure compliance, and respond swiftly to cybersecurity incidents. The Center for Internet Security (CIS) provides clear standards—known as CIS Control 8—that outline how to properly establish, collect, store, and review audit logs.

What Is Audit Log Management and Why Should You Care?

Audit logs are detailed records of system and user activities across your IT environment. They provide a forensic trail that can reveal how, when, and by whom your systems were accessed or altered. Proper audit log management helps detect breaches early, supports regulatory compliance, and ensures you can investigate incidents thoroughly.

CIS Control 8 emphasizes a systematic process that includes:

• Defining logging requirements aligned with business needs
• Ensuring all key systems and applications generate logs
• Centralizing secure storage with time synchronization
• Regular review and response to anomalies
• Retaining logs based on legal and operational needs

Practical Steps for You and Your IT Team

1. Define Your Audit Log Policy: Start by setting a formal process that documents which events must be logged, who reviews them, and for how long logs are kept. 
2. Enable Logging Across All Systems: Collaborate with your IT department to ensure firewalls, servers, workstations, applications, and other devices generate comprehensive logs—both system and user-level events.
3. Centralize and Secure Logs: Use centralized logging solutions to collect logs securely. Ensure all logs have synchronized timestamps via a Network Time Protocol (NTP) server to establish an accurate event timeline.
4. Review Logs Regularly: Establish regular routine checks to spot suspicious activity early. Automate alerts for key events like unauthorized access attempts.
5. Maintain Storage and Retention: Allocate sufficient and safe storage for logs, complying with industry regulations. Implement log rotation policies to manage data volumes.
6. Train Your Teams: Ensure everyone involved understands the importance of audit logs and knows their role in the management and response process.
