Network security

Build boundaries that hold.

Segmentation, controlled egress, name resolution, and useful network telemetry.

THE STARTING POINT

Three things to get right.

  1. Map necessary flows between users, workloads, and data stores.
  2. Restrict tool egress to approved destinations where practical.
  3. Keep enough network context to explain an unexpected connection.

TRY THIS IN THE LAB

A question worth testing.

Diagram a lab assistant’s network dependencies. Separate model calls, retrieval, administration, and telemetry, then review each allowed flow with its owner.

Leave a useful trail.

Write down your starting assumptions, scope, expected behavior, observed behavior, and evidence. A successful test should explain what happened and which question to investigate next.
