Security

Enterprise browsers move enforcement into the user session. Network-centric Zero Trust still owns critical controls such as DNS, routing and non-browser traffic. The interesting architecture is often the combination.

Zero Trust is not resilient just because it is cloud-hosted. Identity, posture, policy, tunnels, DNS and SaaS authentication all create failure domains that need deliberate recovery paths.

The study approach I used for CISSP and CCSP: ISC2 official material, instructor-led training, practice questions, Pete Zerger's Last Mile resources, and more than 20 years of practical experience.

A simple pre-push check for seeing changed, unstaged and staged content before it reaches a public repository.

When a local script is blocked by execution policy, Process scope can be useful for a temporary session without changing the machine-wide setting.

Before creating an emergency bypass, work out whether the failure is identity, posture, policy, DNS, tunnel or origin.
