Jun 1, 2025June 2025 monthly work summary for aws/amazon-ssm-agent focused on strengthening security posture, cross-platform reliability, and maintainability through consolidated hardening and rigorous testing. Key features delivered centered on System Security Hardening: File Permissions and Privileged Access Control, aligning file access controls, command execution restrictions, telemetry configuration, and platform-agnostic validation. No separate bug fixes were logged as major items this month; instead, security hardening work provided a proactive resilience enhancement with supporting tests. Impact: Reduced risk of unauthorized access and privilege escalation, improved telemetry data integrity, and easier audit/compliance. Cross-platform tests (Linux and Windows) increased confidence in behavior consistency across environments, supporting safer deployments and faster incident response. What was delivered, with traceability: - System Security Hardening: File Permissions and Privileged Access Control across the codebase and telemetry config - Enforced non-privileged CLI usage: explicit disallowance of running local CLI command utility as non-privileged user - Telemetry folder permissions hardened to 0700 with update/checks for ongoing enforcement - Cross-platform tests for file privilege checks (Linux and Windows) to ensure consistent behavior - Incremental commits documenting the changes: 6007829179f96d462f0b8a2e32f3c3ddc7bddcf7; cf9c9f991ec74ecf48ea8d21b50398ce90598e57; a18da484eba6db1eade61f8e64749e9b195df7f9; 7e1f69027491f1b6839be156d904ddbc56b811f0

May 1, 2025May 2025: Delivered key observability and stability enhancements for aws/amazon-ssm-agent. Implemented Telemetry Logging Capabilities by augmenting the logging framework with telemetry-specific log levels to improve monitoring and diagnostics; updated release notes to document the new feature. Fixed noisy logging by adjusting Dynamic Configuration Logging Severity—from error to warning when the dynamic config file is missing, reducing noise while ensuring default configuration is populated. Release notes updated accordingly to reflect these changes. These updates improve issue diagnosis, monitoring, and operator experience, delivering measurable business value in reliability and operational efficiency.

Apr 1, 2025April 2025: The aws/amazon-ssm-agent team delivered three focused contributions that enhance performance, security, and reliability. Key changes include an ACL hardened data directory optimization to skip costly recursive hardening on reboot, a correction to the IMDS IPv6 address and port-forwarding deny rule to strengthen security and accuracy in metadata access, and an upgrade to diagnostics and port handling with hibernation logging and cross-platform retry logic for serial ports. These changes reduce reboot overhead, improve security posture, and increase observability across platforms.
