What are the Different Authentication Protocols?
- LDAP (Lightweight Directory Access Protocol): It is mainly used for centralizing the authentication and authorization services. LDAP allows clients to query and modify directory services over TCP/IP.
- Kerberos: A network authentication protocol that securely authenticates users to network services using tickets. Over non-secure networks, Kerberos provides mutual authentication and encrypted communication between parties.
- RADIUS (Remote Authentication Dial-In User Service): A networking protocol that controls authorization, authentication, and accounting management of users connecting and using network services, typically in remote access scenarios.
- TACACS+ (Terminal Access Controller Access-Control System Plus): The account control system that is great at making a difference between its other functionalities like authorization, accounting, etc. It ensures that there is more control over handling network access and management processes.
- OAuth (Open Authorization): An open standard for access delegation, often applied to grant resource access on behalf of a user without revealing her credentials. It is widely employed in web and mobile applications as an identification and validation tool.
- OpenID Connect: It provides an identity layer on top of OAuth 2.0 so that undertakings can prove who end-users are according to what an authorization server authenticated.
What is a User Authentication Policy?
A User Authentication Policy sets out rules and processes to check if users are who they claim to be before allowing them into systems, applications, or data. It puts forward means such as passwords, multi-factor authentication, and biometrics, while also outlining credential management and access control measures. The policy is designed to enhance security, ensure conformity; as well as password confidential information. At the same time, it includes monitoring user activities and educating users on secure practices.
