Security bug ( security defect) is a narrower concept. The window of vulnerability is the time from when the security hole was introduced or manifested in deployed software, to when access was removed, a security fix was available/deployed, or the attacker was disabled-see zero-day attack. A vulnerability with one or more known instances of working and fully implemented attacks is classified as an exploitable vulnerability-a vulnerability for which an exploit exists. Then there are vulnerabilities without risk: for example when the affected asset has no value.
The risk is the potential of a significant impact resulting from the exploit of a vulnerability. The use of vulnerability with the same meaning of risk can lead to confusion. Ī security risk is often incorrectly classified as a vulnerability. Agile vulnerability management refers preventing attacks by identifying all vulnerabilities as quickly as possible.

This practice generally refers to software vulnerabilities in computing systems. Vulnerability management is a cyclical practice that varies in theory but contains common processes which include: discover all assets, prioritize assets, assess or perform a complete vulnerability scan, report on results, remediate vulnerabilities, verify remediation - repeat. In this frame, vulnerabilities are also known as the attack surface. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness. perform unauthorized actions) within a computer system. In computer security, a vulnerability is a weakness which can be exploited by a threat actor, such as an attacker, to cross privilege boundaries (i.e. Security information and event management (SIEM).Host-based intrusion detection system (HIDS).
