1. Authentication Protocols Natalie DeKoker, Lindsay Haley, Jordan Lunda, Matty Ott

2. Protocols and Security Point-to-Point Protocol (PPP) Direct Connection Between Two Computers Authenticates, Encrypts, Compresses Network Control Protocol Runs Atop PPP and negotiates options for PPP

3. Protocols Password Authentication Protocol (PAP) Uses Password to validate Users MS-CHAP Microsoft’s Authentication Protocol for Virtual Private Networks

4. Security Security (AAA) Authentication, Authorization, and Accounting (AAA) Dictates which users have access or control over parts of the network

5. RADIUS Remote Authentication Dial-In User Service (RADIUS) The more common between the AAA standards 3 devices: Radius Server, Network Access Servers (NASs), and group of systems that dial into the network Internet Authentication Service (IAS) most common built in with most Windows Server operating systems FreeRADIUS UNIX/LINUX

10. Kerberos - Strengths Time stamping forces new token requests Prevents 3 rd Parties from intercepting tokens Tokens not likely to be cracked within time span

11. Kerberos - Weaknesses If KDC goes down, no one has access Important to maintain backup Time stamping requires clients to have synchronized clocks
