๐ Quick Study Guide
๐ Vulnerability scanning tools automatically identify security weaknesses in systems.
๐ก๏ธ They help organizations proactively address vulnerabilities before they can be exploited.
๐ธ๏ธ Scanners analyze networks, servers, and applications for known vulnerabilities.
โ ๏ธ Common Vulnerability Scoring System (CVSS) is often used to rank vulnerabilities.
๐ก Vulnerability databases like CVE (Common Vulnerabilities and Exposures) provide information on known vulnerabilities.
โ๏ธ Configuration errors, outdated software, and missing patches are common targets.
๐ Authentication issues and weak encryption are frequently identified vulnerabilities.
