OS hardening: Operating system (OS) hardening is the practice of securing an OS by reducing its surface area of vulnerability, which includes the disabling of unnecessary services, protecting against unauthorized access, applying patches, and enforcing the principle of least privilege. It’s a crucial step during initial system setup and an ongoing policy in maintaining robust security postures, as it helps create a more secure environment that is less susceptible to cyber threats.
