Pattern of the week
Zero-Trust Agent Architecture
- What:
- Verifies agent identity and permissions at every access point, enforcing least privilege and adapting policies based on real-time threat signals.
- When to use it:
- Multi-agent systems handling sensitive data where compromise of one agent must not cascade, or regulated environments requiring audit trails.
- Watch out:
- Verification overhead can severely degrade latency; misconfigured policies lock out legitimate agents or create false security theater.
