A security vulnerability is a weakness in a system, application, or network that can be exploited by attackers to gain unauthorized access or cause harm. These vulnerabilities can arise from various sources, including software bugs, misconfigurations, or inadequate security measures. When exploited, they can lead to data breaches, loss of sensitive information, or disruption of services. Organizations often conduct regular security assessments to identify and address these vulnerabilities. Tools like vulnerability scanners and penetration testing are commonly used to detect weaknesses. By patching vulnerabilities and implementing strong security practices, organizations can better protect their systems and data from potential threats.
