Unpatched Systems

Definition

Unpatched systems are computer systems or software applications that have not received necessary security updates or fixes. These systems contain known vulnerabilities that developers have already addressed with patches, but which remain unapplied by the user or administrator. They present significant security risks, as malicious actors can easily exploit these publicly known weaknesses to gain unauthorized access, deploy malware, or disrupt operations. Maintaining patched systems is a fundamental practice in cybersecurity to protect against common attack vectors.
