Operating System Hardening

Strengthening an OS by reducing its attack surface and applying security controls.

Understanding:

Operating System (OS) Hardening refers to securing an OS by reducing its attack surface, disabling unnecessary services, and implementing security controls to prevent exploitation.

Common Applications and Use Cases:

Enterprise Security – Strengthens corporate systems against malware and unauthorized access.
Cloud & Server Security – Reduces risks in virtualized environments.
Endpoint Protection – Secures workstations and mobile devices from cyber threats.

Best Practices and Security Considerations:

Disable Unused Services and Ports – Reduce potential entry points.
Apply the Principle of Least Privilege – Restrict user and application permissions.
Enable Logging and Monitoring – Detect and respond to suspicious activity.
