Identity management and permission management are the safeguards that prevent this. Both control who can log in and what they can do once inside. Without them, applications turn into open doors. Strong systems track every identity, verify it, and enforce the right level of access. Weak systems let credentials leak and privileges linger too long.
Identity management handles the creation, storage, and lifecycle of user accounts. It ensures the authentication process is consistent, secure, and scalable. It integrates with single sign-on (SSO), multi-factor authentication (MFA), and directory services to protect against unauthorized logins.
Permission management defines and enforces the rules for what each authenticated identity can access. These rules map to roles, groups, or policies. Granular permissions prevent privilege escalation and reduce risk. When implemented correctly, permission management aligns with least privilege principles, making sure users have exactly what they need—no more, no less.
