September 2025 monthly summary for sonic-mgmt focusing on auditd test reliability across hardware SKUs and CI improvements. Key outcomes include stabilizing auditd tests across multiple hardware SKUs by updating the kernel version used in the triggering command, refactoring the checksum logic to depend on system bitness for consistency, and optimizing fixture scope for efficiency. Additionally, fixed the modules_changes test (#20322) to reduce flaky failures, improving CI reliability across environments. These changes enhance cross-SKU validation, reduce test flakiness, and speed up feedback loops for hardware SKU support.

August 2025: Delivered stability and verification-focused enhancements across sonic-mgmt and sonic-buildimage. Implemented log filtering to stabilize KVM tests, hardened auditd test suites with enhanced verification of SYSCALL and PATH logs and rate-limit adjustments, and aligned privileged-container testing with recent hardening efforts. Fixed syntax validation and architecture-aware logging for auditd module_changes rules, with nsenter-based system bitness checks and updates to rule hashes. These changes improved test reliability, security policy validation, and cross-repo consistency, reducing CI flakiness and strengthening audit readiness for production deployments.

July 2025 monthly summary focusing on security auditing improvements and test data alignment across sonic-buildimage and sonic-mgmt. Key efforts delivered a comprehensive Auditd rule coverage and validation, including periodic configuration checks and enhanced event logging for docker-related and module-change activities. Also fixed a test data discrepancy in auditd process_audit checks to ensure checksum expectations are accurate across hardware SKUs, strengthening test reliability and deployment confidence.

April 2025 monthly summary for sonic-net development. Delivered critical automation and reliability improvements across sonic-buildimage and sonic-mgmt, focusing on auditd containerization, health monitoring, and test maintenance. These changes improve security auditing consistency, operational visibility, and deployment reliability, translating to faster incident detection and reduced test flakiness.

Concise monthly summary for 2025-03 focusing on SonicNet development work in sonic-mgmt. Highlights include delivery of features and fixes that strengthen test coverage, reliability, and alignment with service configurations, driving faster, safer releases.

December 2024 monthly summary — Delivered security-focused reliability improvements across sonic-mgmt and sonic-buildimage with clear business value. In sonic-mgmt, TACACS accounting validation and log analysis were enhanced to reduce noise and improve audit accuracy: increase in log analysis timeout, new ignore patterns for auditd-related errors, and refined accounting checks that exclude logs from both regular and admin users. These changes are traceable to commits that include [tacacs] increase timeout value for accounting test and ignore loganalyzer (#15759) and Ignore auditd error in loganalyzer (#15940). In sonic-buildimage, container security hardening for the swss container in docker-orchagent was implemented by replacing the privileged flag with specific capabilities and applying AppArmor/system-path protections to limit access to host resources, increasing the attack surface resistance and enforcing least privilege. This work is linked to commit [docker-orchagent] limit privileged flag for swss container (#17598).

November 2024: Delivered a TACACS audit log visibility enhancement in sonic-mgmt, significantly improving log discoverability and troubleshooting efficiency. Implemented --no-pager for journalctl in the TACACS utility to ensure all auditd logs related to audisp-tacplus re-initialization are visible in a single view, enabling easy grep/search and faster diagnosis of TACACS+ configuration reloads. No major bugs fixed for sonic-mgmt this month.
