A vulnerability is a weakness or flaw in software, hardware, or processes that attackers can exploit.
Why it matters:
- Common sources include outdated software, weak passwords, or misconfigurations.
- Regular scanning and patching reduce risk.
- Exploited vulnerabilities often lead to data breaches or ransomware attacks.
Pro tip: Prioritize fixing vulnerabilities based on severity and exposure — not all weaknesses pose equal risk.
