Last Reviewed: July 19, 2025
Owner: Security & Compliance Team
1. Purpose
The purpose of this policy is to ensure that DevSecOpsBook maintains adequate logging and monitoring practices to detect, respond to, and investigate security incidents, system failures, and anomalous activities in alignment with SOC 2 Trust Services Criteria (specifically CC7.2, CC7.3, and CC7.4).
2. Scope
This policy applies to all production systems, applications, services, network devices, infrastructure components, and cloud platforms that support DevSecOpsBook’s business operations.
3. Logging Requirements
- 3.1 Event Types Logged
- Authentication events (login, logout, failed attempts)
- Privileged account usage
- User access to sensitive data
- Changes to configurations, roles, permissions, and source code
- System and application errors
- Network traffic anomalies
- 3.2 Log Content
Each log entry must contain:- Timestamp (in UTC)
- Source (system/service)
- Event type
- User ID or system ID initiating the event
- IP address (if applicable)
- Outcome (success/failure)
- 3.3 Centralized Logging
All logs must be forwarded to a centralized logging platform with access control, tamper resistance, and search capabilities.
4. Monitoring & Alerting
- 4.1 Real-Time Monitoring
Security-relevant logs must be continuously monitored for suspicious activity using automated tools (e.g., SIEM, anomaly detection systems). - 4.2 Alerting Criteria
Alerts must be triggered for:- Multiple failed login attempts
- Privileged access outside of business hours
- Unauthorized changes to infrastructure/code
- Malware or intrusion detection system (IDS) alerts
- Disabling or modification of logging configurations

Alerts must be reviewed by the Security Team within defined SLAs. Confirmed incidents will trigger the Incident Response process (see [Incident Response Policy]).
5. Log Retention & Protection
- 5.1 Retention Period
Logs must be retained for a minimum of 1 year, with critical security logs stored for at least 90 days in immediately accessible format. - 5.2 Integrity and Tamper Resistance
- Logs must be stored in write-once-read-many (WORM) or immutable formats.
- Regular checksums and integrity validation are required.
- Access to modify or delete logs must be restricted and logged.
6. Access Control
- Only authorized personnel (e.g., DevOps, Security team) are allowed to access logs.
- Access must be role-based and reviewed quarterly.
- All access to the logging platform must itself be logged.
7. Review & Audit
- 7.1 Weekly Review
Security personnel must review logs for anomalous activity at least weekly. - 7.2 Quarterly Audit
Quarterly audits must validate that all required log sources are configured and that alert rules are functional.
