Logging & Audit Trails
Plain English Translation
Organizations must implement logging and audit trail mechanisms that record all access to, and activity within, information systems containing personal data. Logs must capture alterations, deletions, and additions to records, and must be regularly monitored to detect unauthorized or anomalous activity. Audit trails provide the accountability trail needed to investigate incidents and demonstrate compliance.
Technical Implementation
Use the tabs below to select your organization size.
Required Actions (startup)
- Enable basic application and database-level audit logging to capture user logins, file access, and data modifications.
Required Actions (scaleup)
- Forward system and application logs to a centralized log management platform to ensure immutability and facilitate easier querying during investigations.
Required Actions (enterprise)
- Deploy a dedicated Security Information and Event Management (SIEM) system with automated anomaly detection, alerting on suspicious user behavior across all environments.
Evidence Required
The law requires organizations to implement hardware, software, and procedural mechanisms to record and examine system access, and to actively monitor and track any alterations, deletions, or additions to personal data.
While the IRR does not mandate a specific duration, logs should be securely retained in accordance with the organization's formal data retention policy to adequately support post-incident investigations and ongoing compliance audits.
Access logs should definitively capture the user's identity, the precise timestamp of the event, the specific system or record accessed, and the exact nature of the action (e.g., read, create, update, delete).
Yes, IRR Section 28(c) explicitly requires the monitoring and tracking of any alterations, deletions, or additions made to personal data records within an information system.
Audit trails provide objective, historical evidence of data processing activities, enabling organizations to prove accountability, detect unauthorized behavior, and ensure the overall integrity of personal information.
Required technical measures include data encryption, network protection tools like firewalls, vulnerability assessments, and comprehensive mechanisms to record and audit system access and activity.
Organizations should utilize automated software and database mechanisms that instantly generate immutable log entries for all transactional changes and user access events across their infrastructure.
Designated security personnel, system administrators, or internal auditors should be tasked with periodically reviewing audit logs to proactively detect anomalies, unauthorized access, or potential security breaches.
Yes, comprehensive access logs are strictly required for all information systems containing personal data, with heightened scrutiny and monitoring expected for environments processing sensitive personal information.
Audit logs act as crucial forensic evidence, allowing incident response teams to accurately determine the root cause, identify the specific data compromised, and establish a precise timeline of the breach.
Audit logging controls often fail because teams cannot consistently prove that logs are enabled, reviewed, and retained. Tools like WatchDog Security's Compliance Center can help map log-review records, audit logging policies, and evidence artifacts to RA 10173 control requirements so gaps are easier to identify and remediate.
Audit trails depend on both clear procedures and correctly configured systems. Tools like WatchDog Security's Policy Management can help maintain version-controlled audit logging and log retention policies, while WatchDog Security's Posture Management can help identify misconfigurations that weaken logging coverage or monitoring readiness.
