Avito Details Security Gates Implementation to Enforce Vulnerability Remediation Without Disrupting Developers

Alexander Trifanov, head of Application Security at Avito, shares a detailed case study on building security gates that block risky deployments while preserving developer experience. The approach relies on asynchronous scanning pipelines using SAST, SCA, secret detection, and YAML Security tools aggregated in ASOC or SOAR systems. Gates are placed at multiple lifecycle points including pre-receive hooks, CI/CD deployment stages, and manual unit-level overrides via a red-button mechanism. Strict false-positive management, deduplication, and emergency bypass controls are highlighted as essential for scalability across thousands of developers. The article covers pre-receive gating limited to ten-second scans, separate library update flows, and Kubernetes integration attempts with Kyverno. Avito reports that even unused red-button capabilities significantly improve SLA compliance without frequent enforcement actions.

Container Image Risks: Why Skipping Verification Today Breaks Your Service Tomorrow

Technical leader Nikita from Cloud.ru details four recurring container security failures observed across client environments. The article examines untracked vulnerabilities in high-privilege components such as the NVIDIA GPU operator, supply-chain compromises affecting even trusted tools like Trivy, persistent secret leakage patterns, and CI/CD pipeline exposure. Real incidents include a 2025 NVIDIA container toolkit exploit that enabled lateral movement to worker nodes and a 2026 Trivy GitHub compromise that poisoned over seventy image tags. The author stresses that pinning to image tags is insufficient and recommends full SHA256 hashes, private registries with caching, Cosign signatures validated by Kyverno or Connaisseur, and pre-commit secret scanning. Practical recommendations include automated CVE notifications and immediate patching of privileged components rather than waiting for sprint cycles.
