Security Hardener
Overview
Security hardening is the process of reducing a system's attack surface by disabling unnecessary services, applying secure configurations, and enforcing the principle of least privilege across all layers. This skill covers hardening practices for operating systems, containers, networks, applications, databases, and cloud infrastructure.
CIS Benchmarks
The Center for Internet Security (CIS) publishes configuration benchmarks for virtually every technology. These are the industry-standard baseline for hardening.
