Datacenter Hardening
Resegmentation and hardening of 50+ Linux and Windows servers.
Challenge
A flat network and broad access elevated lateral-movement risk. Legacy firewall rules and shared admin accounts had stalled internal audit.
Approach
Phased segmentation, Linux/Windows hardening baselines, port restriction, shared-account removal, and centralized logging to prepare for SIEM.
Results
- 70% reduction in publicly exposed ports
- Prod/Stage environment isolation
- SIEM onboarding readiness
