system hardening

System hardening is the process of strengthening a computer or network to reduce security risks and protect against unauthorized access or attacks. It involves removing unnecessary features, updating software, configuring security settings, and applying access controls to minimize vulnerabilities. Think of it as locking doors and windows, removing valuables, and installing security alarms to make it harder for intruders to break in or cause harm. The goal is to make the system as secure as possible without impairing its essential functions, ensuring safer operation and data protection.
