An authentication protocol allows two entities to verify each other's identity. It is a type of computer communications protocol designed to transfer authentication data between two entities, allowing the receiving entity to authenticate the connecting entity. There are several types of authentication protocols including Kerberos, NTLM, SSL/TLS, digest authentication, smart cards, VPN and RAS. The authentication process involves determining a user's identity and access levels through security mechanisms before authorizing access to system resources.

2. INTRODUCTION
An authentication protocol is a type of computer communications protocol or
cryptographic protocol specifically designed for transfer of authentication data
between two entities. It allows the receiving entity to authenticate the connecting
entity.

3. WHAT IS THE PROCESS OF
AUTHENTICATION
security mechanism used to determine users & client privileges or access
levels related to system resources, including computer programs, files,
services, data and application features. Authorization is normally preceded
by authentication for user identity verification. System administrators are
typically assigned permission all user resources.

4. AUTHENTICATION TYPES
 Kerberos authentication protocol
 NT LAN Manager (NTLM) authentication protocol
 Secure Sockets Layer/Transport Security Layer (SSL/TLS)
 Digest authentication
 Smart cards
 Virtual Private Networking (VPN) and Remote Access Services (RAS)

5. AUTHENTICATION SERVICE FEATURES
 Account Locking
 Authentication Chaining
 Fully Qualified Domain Name Mapping
 Persistent Cookies
 Session Upgrade
 JAAS Shared State
 Security

6. STEP TO ACCESS
 Permissions
 Police
 Rights

7. AUTHENTICATION PROTOCOLS
 PAP - Password Authentication Protocol
 CHAP - Challenge-handshake authentication protocol
 EAP - Extensible Authentication Protocol
 AAA architecture protocols

8. SUMMARY
The final step in the Authentication Process is to make a determination. The
determination must be made by a qualified individual capable of interpreting
and weighing all of the available evidence as produced by the various
authentication steps.
