A security breach is an incident where unauthorized individuals gain access to data, systems, or networks. Breaches can result from various attack vectors including phishing, malware, exploitation of vulnerabilities, insider threats, or physical security failures. Breaches can lead to data theft, financial loss, reputational damage, and legal consequences. Organizations should have breach response plans that include containment, notification (per regulatory requirements), investigation, and remediation. Prevention through layered security controls is the best defense.
