Logs access is the most dangerous blind spot in modern infrastructure. When proxies route internal requests, they often touch sensitive logs from builds, deployments, and CI pipelines. Attackers know these logs can contain secrets, API keys, or configuration data. Without strict access control, a breach in the proxy layer becomes a breach across the entire supply chain.
Supply chain security demands more than dependency scanning. It requires visibility into every point where logs flow. Each proxy, whether reverse or forward, must enforce authentication and authorization before granting access. Logs must be encrypted at rest and in transit. Compression and storage policies must be clear and immutable. Audit trails must show exactly who pulled log data and when.
The problem grows in distributed systems. Multiple services talk through proxies, often deployed with default settings. Those defaults can leak. They grant broad read permissions to internal logs. That’s why mapping your proxy topology to your log storage is critical. Identify choke points. Add zero-trust policies. Rotate credentials on a fixed schedule.
