Microservices Access Proxy with Zero Standing Privilege

The request hits your desk: secure hundreds of microservices, no standing access for anyone, zero trust baked into every call. No delays. No excuses.

Microservices Access Proxy with Zero Standing Privilege is the answer. It’s not theory. It’s an architectural pattern that enforces access only when needed, for exactly as long as needed, and nothing more.

What It Is
A microservices access proxy sits between your services and the clients or internal systems that call them. It intercepts requests, checks identity, applies policy, and routes traffic. When designed for Zero Standing Privilege (ZSP), no account—human or machine—keeps ongoing permission to any microservice. Credentials exist only for the duration of a transaction.

Why It Matters
Persistent access means persistent risk. Internal accounts left open become attack vectors. ZSP removes idle privilege. Each request is verified, authorized, and logged. Every session is short-lived, every credential disposable. Attack surfaces shrink. Compliance teams stop chasing static entitlements.

How It Works

  1. Identity Verification – The proxy authenticates every call.
  2. Policy Enforcement – Authorization rules checked against dynamic context: request origin, time, role, service sensitivity.
  3. Ephemeral Credentials – Tokens granted just-in-time, auto-expire after use.
  4. Granular Routing – Each microservice receives only the minimal request scope allowed.
  5. Continuous Auditing – Logs feed into security monitoring and anomaly detection.

Design Principles

  • No standing keys or passwords in config files.
  • All privileges regulated by the proxy.
  • Isolation between services to limit lateral movement.
  • Automation to revoke unused permissions instantly.

Benefits

  • Reduced blast radius of intrusions.
  • Stronger compliance posture under frameworks like SOC 2, ISO 27001, HIPAA.
  • Faster onboarding/offboarding with no manual credential cleanup.
  • Unified control plane for microservices access.

Microservices Access Proxy and Zero Standing Privilege are not optional for modern architectures—this is the baseline for secure, scalable service interaction. Static access is legacy. Ephemeral access is future-proof.
