Exploits & Vulnerabilities with Introduction to Metasploit

Exploits and Vulnerabilities In computer security, a vulnerability is a weakness which can be exploited by a Threat Actor like an attacker, to perform unauthorized actions within a computer system. These vulnerabilities have to be managed to inform the developers to patch it. Vulnerability management involves identifying,classifying,remediation and mitigating vulnerabilites in computer systems. The well known CVE (Common Vulnerabilities and Exposures) system is used to record and maintain the system.
