MSFTSEC02-BP02 Implement logging to track access and authorization changes
Regularly log, analyze, and audit user access and authorization events in your Microsoft systems. Consolidate security events from Microsoft applications and databases with other architectural components to enable comprehensive tracing during security incidents. Implement a centralized security information and event management (SIEM) system to automate event analysis, allowing your operations team to identify unusual or suspicious activities.
This integrated approach to security monitoring enhances your ability to detect and respond to potential threats across your entire Microsoft environment, strengthening your overall security posture and enabling more effective incident management.
Desired outcome: Establish comprehensive logging and monitoring capabilities that capture, analyze, and correlate access and authorization events across Microsoft workloads, enabling rapid detection of security incidents and providing detailed audit trails for compliance and forensic analysis.
Common anti-patterns:
-
Collecting logs from individual systems without centralized aggregation and correlation, making it difficult to identify patterns or conduct comprehensive security analysis across the Microsoft environment.
-
Focusing only on successful authentication events while ignoring failed attempts, authorization changes, and privilege escalations that could indicate security threats or policy violations.
-
Storing logs locally on individual systems without proper retention, backup, or protection mechanisms, risking log loss during security incidents when they are most needed for investigation.
Benefits of establishing this best practice:
-
Enhanced threat detection through comprehensive logging that captures authentication attempts, authorization changes, and access patterns, enabling early identification of suspicious activities and potential security breaches.
-
Improved incident response capabilities through centralized log aggregation and correlation that provides security teams with complete visibility into user activities and system events during security investigations.
-
Strengthened regulatory posture through detailed audit trails that document user access, privilege changes, and administrative activities, supporting regulatory requirements and internal security policies.
Level of risk exposed if this best practice is not established: Medium
Implementation guidance
Implementing comprehensive access and authorization logging requires a systematic approach to log collection, centralization, and analysis. Focus on capturing relevant security events from each Microsoft workload component while protecting, retaining, and documenting for analysis and compliance purposes.
Implementation steps
-
Configure Windows Event Logging on your Microsoft workload systems to capture security events, including authentication attempts, privilege changes, and administrative activities.
-
Enable SQL Server audit logging to track database access, permission changes, and data access patterns for comprehensive database security monitoring.
-
Set up Amazon CloudWatch Logs or AWS CloudTrail to collect and centralize logs from Microsoft workloads running on AWS infrastructure.
-
Configure log forwarding from Microsoft applications and databases to a centralized SIEM solution such as Amazon Security Lake or third-party security platforms.
-
Implement log parsing and normalization for consistent event formats, enabling effective correlation across different Microsoft technologies and AWS services.
-
Set up automated alerting and monitoring rules to detect suspicious access patterns, failed authentication attempts, and unauthorized privilege escalations.
-
Establish log retention policies that meet regulatory requirements while balancing storage costs and operational needs for security analysis.
-
Create regular reporting and analysis procedures to review access patterns, identify security trends, and validate the effectiveness of access controls.
