AI Cyber Defense / Network edge and segmentation
AI Cyber Defense: Close east-west access exposed by flat server networks
Create staged workload policies with named dependencies, an observation period and a rollback owner. Protect identity, backup and management services first.
Environment and inputs: Enterprise routers, switches, firewalls, VPNs and workload segmentation; use syntax and features supported by the deployed platform.
Scenario and goal
A single compromised workload can discover peer services when server subnets imply broad mutual trust.
Why it matters
For this scenario, assume discovery can enumerate alternate listeners, address families and routes repeatedly. Define the boundary as permitted communication between named roles, rather than physical network location alone. Separate management, control and application traffic when reviewing the effect of a change. Encryption protects a transport relationship but does not establish that its peer should reach every destination behind it.
Evidence to collect
Build a dependency matrix from representative flow history and validate it with service owners; absence of traffic is not proof a dependency is unnecessary.
Validate with an authorized exercise
Use a test application transaction and a forbidden peer connection after each policy stage; verify both service continuity and reduction in reachable destinations.
Rollout and checks
Export the effective policy and routes before a change and confirm a tested recovery channel. Apply the narrowest change to a representative test segment first. Measure permitted application transactions and forbidden reachability after deployment, including alternate paths. Review deny counters with source and destination context before concluding that a policy is correct or safe to broaden.
Scope and limits
This guide proposes a defensive test; it is not a tested production design. Check platform support and local requirements. References explain the mechanisms but do not certify the design. Behavior alone does not prove AI involvement.
