Vulnerability management is the "cyclical practice of identifying, classifying, prioritizing, remediating, and mitigating" software vulnerabilities. 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. They may also be identified by consulting public sources, such as NVD, or subscribing to a commercial vulnerability alerting service such as Symantec's DeepSight Vulnerability Datafeed[promotional source?] or Accenture's Vulnerability Intelligence Service.[promotional source?] Unknown vulnerabilities, such as a zero-day, may be found with fuzz testing. Fuzzy testing 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 (such as attempting to overwrite a system file).
Project vulnerability management
Project vulnerability is the project's susceptibility to being subject to negative events, the analysis of their impact, and the project's capability to cope with negative events. Based on Systems Thinking, project systemic vulnerability management takes a holistic vision, and proposes the following process:
1. Project vulnerability identification.
2. Vulnerability analysis.
3. Vulnerability response planning.
4. Vulnerability controlling – which includes implementation, monitoring, control, and lessons learned.
Coping with negative events is done, in this model, through:
- resistance – the static aspect, referring to the capacity to withstand instantaneous damage, and
- resilience – the dynamic aspect, referring to the capacity to recover in time.
Antifragility is a concept introduced by Nassim Nicholas Taleb to describe the capacity of systems to not only resist or recover from adverse events, but also to improve because of them. Antifragility is similar to the concept of positive complexity proposed by Stefan Morcov.
