Vulnerabilities can be scored for risk according to the Common Vulnerability Scoring System or other systems, and added to vulnerability databases. As of November 2024 [update] , there are more than 240,000 vulnerabilities [ 1 ] catalogued in the Common Vulnerabilities and Exposures (CVE) database.
Common Vulnerabilities and Exposures (CVE) is a dictionary of common names (i.e., CVE Identifiers) for publicly known information security vulnerabilities. CVE's common identifiers make it easier to share data across separate network security databases and tools, and provide a baseline for evaluating the coverage of an organization's security ...
An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
A security bug or security defect is a software bug that can be exploited to gain unauthorized access or privileges on a computer system. Security bugs introduce security vulnerabilities by compromising one or more of: Authentication of users and other entities [1] Authorization of access rights and privileges [1] Data confidentiality; Data ...
A remote exploit works over a network and exploits the security vulnerability without any prior access to the vulnerable system. A local exploit requires prior access or physical access to the vulnerable system, and usually increases the privileges of the person running the exploit past those granted by the system administrator. Exploits ...
Vulnerability management is the "cyclical practice of identifying, classifying, prioritizing, remediating, and mitigating" software vulnerabilities. [1] Vulnerability management is integral to computer security and network security , and must not be confused with vulnerability assessment .
Vulnerability assessment is a process of defining, identifying and classifying the security holes in information technology systems. An attacker can exploit a vulnerability to violate the security of a system. Some known vulnerabilities are Authentication Vulnerability, Authorization Vulnerability and Input Validation Vulnerability. [1]
A penetration test can help identify a system's vulnerabilities to attack and estimate how vulnerable it is. [7] [5] Security issues that the penetration test uncovers should be reported to the system owner. [8] Penetration test reports may also assess potential impacts to the organization and suggest countermeasures to reduce the risk. [8]
