System Access Logs

Access logs should capture the user or service identity, timestamp, source (e.g., IP/device), the event type (e.g., login success/failure, MFA challenge, role change), and the resource or system accessed. This supports accountability, detection of unauthorized access, and incident investigation.

Retention should be defined based on investigation needs, operational requirements, and any contractual or legal obligations. Many organizations retain security-relevant access logs for a period long enough to support incident response, threat hunting, and audit inquiries, and use tiered storage (hot vs. archived) to balance cost and access.

Access log analysis should focus on identifying patterns of compromise such as repeated failed login attempts, impossible travel, abnormal access times, unusual privilege changes, or access to sensitive systems outside expected workflows.

Implement real-time ingestion and alerting for high-risk events such as privileged account usage, repeated authentication failures, suspicious sign-in geographies, disabling of security controls, and large or unusual data access patterns. WatchDog Security can support this by using Posture Management to detect risky logging and monitoring configurations and by tracking remediation actions in the Risk Register with owners, due dates, and treatment plans.

Protect integrity by centralizing logs quickly, restricting access, and using immutable or append-only storage where feasible. Use encryption and cryptographic integrity controls (e.g., hashing/signing) so tampering is detectable, and monitor for gaps in logging that may indicate disruption. WatchDog Security can help by storing supporting evidence and review notes in Compliance Center and by using Secure File Sharing to exchange log exports with auditors under encrypted, access-controlled workflows.

Logs should be stored securely with encryption at rest, strict access controls, and clear retention/lifecycle rules. Many programs use separate tiers (hot for active analysis, cold for long-term retention) and ensure backups/archives are protected from unauthorized deletion.

Access logs enable investigators to reconstruct timelines, identify compromised identities, determine what resources were accessed, validate whether privilege escalation occurred, and scope the potential impact. They are also used to validate containment actions and confirm return-to-normal activity. WatchDog Security can support investigations by tying log exports, alerts, and incident artifacts to a single evidence package in Compliance Center and maintaining an auditable chain of custody for shared files via Secure File Sharing.

Most security and governance expectations require maintaining audit logs as a technical safeguard to support accountability and detect misuse. Requirements generally focus on logging user activities, exceptions, security events, and administrative actions—plus ensuring logs are protected, retained, and reviewable.

WatchDog can help teams validate that logging is enabled and appropriately configured across connected environments by surfacing gaps such as missing audit logs, weak retention settings, excessive permissions to log stores, or disabled monitoring/alerting. It can also help link evidence (exports, alerts, review records) to tickets and governance workflows so logging remains operational over time.

A GRC platform can centralize access-log evidence, map it to controls across frameworks, and preserve review records for audits and investigations. With WatchDog Security, teams can use Compliance Center to package exports and attestations, and Trust Center to sync customer-facing evidence while keeping internal audit trails organized.

Automation tools can continuously check whether audit logging is enabled, retained correctly, and protected from tampering, then alert on gaps. WatchDog Security Posture Management runs agentless checks to detect misconfigurations, and Asset Inventory helps ensure coverage across cloud, SaaS, and identity systems so critical log sources are not missed.
