Concept
Vulnerability management
Résumé
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, vendor specific security updates or subscribing to a commercial vulnerability alerting service. 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 ).
Correcting vulnerabilities may variously involve the installation of a patch, a change in network security policy, reconfiguration of software, or educating users about social engineering.
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:
-
Project vulnerability identification. -
Vulnerability analysis. -
Vulnerability response planning. -
Vulnerability controlling – which includes implementation, monitoring, control, and lessons learned.

Threat (computer)
In computer security, a threat is a potential negative action or event facilitated by a vulnerability that results in an unwanted impact to a computer system or application. A threat can be either a negative "intentional" event (i.e. hacking: an individual cracker or a criminal organization) or an "accidental" negative event (e.g. the possibility of a computer malfunctioning, or the possibility of a natural disaster event such as an earthquake, a fire, or a tornado) or otherwise a circumstance, capability, action, or event.
Cyberattaque
Une cyberattaque est un acte offensif envers un dispositif informatique à travers un réseau cybernétique. Une cyberattaque peut émaner de personnes isolées ou d'un groupe de pirates informatiques, éventuellement étatique. Une cyberattaque est presque systématiquement malveillante, mais peut s'inscrire dans une approche éthique, lorsqu'elle a pour seul but de mettre en évidence une faille de sécurité. Il existe de très nombreuses définitions selon les pays, les ONG, les organisations internationales Pour A.
IT risk
Information technology risk, IT risk, IT-related risk, or cyber risk is any risk relating to information technology. While information has long been appreciated as a valuable and important asset, the rise of the knowledge economy and the Digital Revolution has led to organizations becoming increasingly dependent on information, information processing and especially IT. Various events or incidents that compromise IT in some way can therefore cause adverse impacts on the organization's business processes or mission, ranging from inconsequential to catastrophic in scale.
