Vulnerability Scanning

Vulnerability assessment is a crucial process in cybersecurity aimed at identifying, evaluating, and addressing security flaws in systems, networks, and applications. By proactively detecting vulnerabilities, organizations can minimize the risk of cyber-attacks and strengthen their defenses.

What is Vulnerability Assessment?​

Vulnerability assessment is a systematic approach to identify, categorize, and prioritize security vulnerabilities in IT systems. It helps organizations understand where their weakest points are and how to fix them before cybercriminals can exploit them.

Key Topics in Vulnerability Assessment​

1. Types of Vulnerability Assessments​

  • Network Vulnerability Assessment: Focuses on identifying weaknesses in network infrastructure.
  • Web Application Vulnerability Assessment: Identifies flaws in web apps, such as SQL injection or cross-site scripting (XSS).
  • System/Host Vulnerability Assessment: Examines the security of operating systems, software, and hardware.
  • Database Vulnerability Assessment: Focuses on database security and access control vulnerabilities.

2. Vulnerability Scanning Tools​

  • Nmap: Scans for open ports and vulnerabilities in networks.
  • Nessus: Detects vulnerabilities in software and configurations.
  • OpenVAS: Open-source platform for vulnerability scanning.
  • Qualys: Cloud-based solution for continuous vulnerability management.

3. Vulnerability Assessment Process​

  1. Discovery: Identifying assets and systems to assess.
  2. Scanning: Using tools to detect vulnerabilities.
  3. Risk Analysis: Evaluating the severity of detected vulnerabilities.
  4. Reporting: Documenting vulnerabilities and recommending fixes.

4. Common Vulnerabilities​

  • Unpatched Software: Missing critical security patches.
  • Weak Passwords: Easily guessable or default credentials.
  • SQL Injection: Exploiting database
