Access control

concept · part of Security

Access control refers to the selective restriction of access to data or systems. Insufficient access controls can lead to unauthorized data exposure, as seen in the Anthem breach. Best practices include role-based access control (RBAC), multifactor authentication (MFA), and the principle of least privilege.

Multifactor authentication is recommended to prevent unauthorized access, especially for third-party vendors and public-facing endpoints, as highlighted by the Target breach lesson.
