Multi-Site ADDomain Hardening

CIS Benchmark controls applied across infrastructure servers, and Active Directory domain hardening carried out across the hotel sites of a regional hospitality group operating in four UAE emirates.

A multi-site estate had accumulated configuration that no longer matched a defensible baseline. Hardening had to be applied consistently across sites without breaking the services those sites depend on daily.

• 01CIS Benchmarks adopted as the configuration baseline for infrastructure servers.
• 02Active Directory domain hardening applied across the domain rather than per server.
• 03Group Policy used as the delivery mechanism for consistent control enforcement.
• 04Changes staged and verified per site to contain operational risk.

• Assessed existing server and domain configuration against CIS Benchmark controls.
• Applied CIS Benchmark controls across infrastructure servers.
• Performed Active Directory domain hardening across multiple hotel sites.
• Verified control application and remediated deviations.

Infrastructure servers and the Active Directory domain were brought onto a consistent, benchmark-aligned configuration baseline across the group’s sites.
