What is Vulnerability Management?
Vulnerability management is the "cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities", particularly in software. Vulnerability management is integral to computer security and network security, and must not be confused with Vulnerability assessment.
Vulnerabilities can be discovered with a vulnerability scanner, which analyzes a computer system in search of known vulnerabilities,such as open ports, insecure software configurations, and susceptibility to malware infections. Unknown vulnerabilities, such as a zero-day,may be found with fuzz testing, which can identify certain kinds of vulnerabilities, such as a buffer overflow with relevant test cases. Such analysis can be facilitated by test automation. In addition, antivirus software capable of heuristic analysis may discover undocumented malware if it finds software behaving suspiciously.
