Authentication and authorization are fundamental concepts in computer security, often
used together to control access to resources.
- Authentication focuses on user identity verification, confirming if a user is
legitimate. Authorization deals with permissions, deciding what actions or resources an authenticated user
is allowed to access.
2. Authentication involves login credentials validation, like usernames and
passwords. Authorization involves defining and managing roles, permissions, and access control lists
(ACLs).
3. Authentication grants access based on valid credentials. Authorization grants
specific permissions and controls users' actions within a system based on their roles and
privileges.
