Vulnerability
A vulnerability is a weakness or flaw in a system that can be exploited by an adversary to cause harm. It's like an unlocked door in a secure building, providing a potential entry point for an attack.
TECHNICAL DEFINITION
In cybersecurity and defense, a vulnerability is a quantifiable weakness in a system, software, hardware, or procedure that a threat actor can exploit to compromise the confidentiality, integrity, or availability (CIA triad) of a critical information asset or operational capability.
BACKGROUND
Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.

USAGE NOTE
Vulnerabilities are cataloged with a CVE identifier and scored using CVSS to prioritize patching and defense resources on military and intelligence networks.
DEVELOPERS
Organizations developing technology related to Vulnerability.
