ISO 27005 defines vulnerability as: A weakness of an asset or group of assets that can be exploited by one or more threats, where an asset is anything that has value to the organization, its business operations, and their continuity, including information resources that support the organization's mission There are vulnerabilities that are not related to software: hardware, site, personnel vulnerabilities are examples of vulnerabilities that are not software security bugs.Ĭonstructs in programming languages that are difficult to use properly can manifest large numbers of vulnerabilities. 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 to 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. ![]() Vulnerabilities can be exploited by a threat actor, such as an attacker, to cross privilege boundaries (i.e. Vulnerabilities can be weaknesses in either the hardware itself, or the software that runs on the hardware. Vulnerabilities are flaws in a computer system that weaken the overall security of the device/system.
