System Hardening
Noun · Security & Infosec
Definitions
A governance or operations concept focused on system hardening as part of ongoing security management. It shows up in application security, identity, infrastructure, or incident response work depending on the environment. Teams use the concept to prevent abuse, detect adversary activity earlier, or define stronger control boundaries during engineering, testing, and operations.
In plain English: System Hardening is the practical security idea behind a control, weakness, or safeguard. It matters because it changes how attackers succeed or defenders reduce risk.
Example: "During the review, the team focused on System Hardening after telemetry and testing showed it was the fastest way to reduce exposure, tighten controls, and close a realistic attack path before the next production release."
