PROFILE

Afek Berger

Afek Bar built and enhanced core security and observability features across the kubescape/node-agent and related repositories, focusing on scalable event processing, robust runtime policy enforcement, and reliable incident reporting. Leveraging Go, eBPF, and Kubernetes, Afek refactored container tracking to use container IDs, introduced asynchronous enrichment pipelines, and implemented efficient HTTP and DNS monitoring. In kubescape/node-agent, he improved process tree management for concurrency and batch event handling, while in armosec/armoapi-go, he expanded alert data models for traceability and cloud context. His work emphasized test automation, CI stability, and performance tuning, resulting in deeper, more maintainable backend security infrastructure.

Aug 1, 2025

August 2025 performance summary: Delivered stability and scale improvements across system-tests, node-agent, and armoapi-go. Upgraded test environment Node-agent to v0.0.161 to boost coverage and reliability; hardened process-tree management for concurrency with SafeMap, exit handling, and updated tests; tuned node-agent performance under load with configuration defaults, worker pool adjustments, and ordered event queues; enabled tracer profiling and refined procfs behavior to reduce churn; introduced a configurable LRU DNS cache to optimize lookups and memory usage; laid groundwork for runtime security rules with a data model and agent-version constraints. These changes reduce test flakiness, improve resource utilization, enable scalable policy enforcement, and accelerate feedback cycles for developers and security operators.

May 1, 2025

May 2025 monthly summary focusing on delivering reliability, traceability, and efficiency improvements across node-agent, system-tests, armoapi-go, and helm-charts. Key features were implemented to improve container tracking, network monitoring, and alerting workflows, while major bugs were fixed to stabilize updates and event processing. The work also emphasized testing stability and reproducibility in CI and runtime environments, enabling safer deployments and faster remediation. Key outcomes include: - Improved container tracking by switching to container IDs, with tests to prevent application profile lockups during container restarts. - Streamlined network monitoring through a refactored HTTP sniffer that uses data syscalls and socket inode as a unique connection identifier, removing obsolete state maps. - Enhanced rule management with enrichment failure handling, learning-period evaluation, and a cooldown mechanism to reduce alert fatigue. - Strengthened data traceability with a new UniqueID field for CdrAlert in armoapi-go. - Stability and reliability improvements in testing and CI, including CSPM data integrity fixes, flaky test mitigation, and caching and version pinning for consistent test environments.
