Background for this topic.

Breach means unauthorized access to a computer system or network that exposes or steals sensitive data like personal details, passwords, or proprietary information. Attackers often exploit software flaws, weak passwords, or social engineering to gain entry. Breaches can also result from insiders misusing access or accidental data exposure.

Understanding breaches is crucial because they reveal weaknesses in security controls and can lead to data theft or operational disruption. Effective defenses include promptly patching vulnerabilities, enforcing strong authentication, and segmenting networks to limit attacker movement. Detecting breaches quickly through monitoring and logging helps contain damage and guide targeted remediation efforts to secure affected systems and data.
