Endpoint Application Control & Browser Hardening
Engineering policy controls while preserving compatibility with business applications.
This retrospective describes professional responsibilities at a high level. Organization-specific data, policy names, hostnames, identities, sensitive configuration details, and internal records are deliberately excluded. The description does not claim a completed enterprise-wide rollout unless documented.
Engineering problem
The work involved aligning browser configuration with CIS recommendations while addressing application-control failures and avoiding conflicting settings across Group Policy and Intune.
Methodology
- Compared Chrome security baseline requirements with the organization's existing Group Policy and Intune deployment approaches.
- Investigated AppLocker publisher, hash, and packaged-app rules using local enforcement events, signature information, and executable metadata.
- Designed pilot-based verification, backup and reporting steps, and rollback-aware changes for policies affecting business-critical applications.
Documented outcome
Documented policy decisions, verification commands, and application compatibility considerations. Pilot and configuration work are represented separately from any unverified full-environment deployment.
