3. Password Authentication Protocol
Also known as (PAP)
- a type of cryptographic protocol with the purpose of authenticating entities wishing to communicate securely with the use of a password

4. How P.A.P. is used… Networking Operating System (N.O.S.)
- designed to support workstation,
personal computer, and other
terminals connected on a local area
network
- provide sharing, name directory,
security, etc.

5. Types of different NOS involved in P.A.P.
Peer-to-Peer
Client/Server
(Remote Authentication Dial In User Service)
Point-to-Point Protocol

6. Peer-to-Peer
Users allowed to share resources or files located on their computers
Accessibility, ease of setup, less hardware needed
Downside..
- no central location for storage
- lack oh high security

7. Client/Server (R.A.D.I.U.S.)
Server enables multiple clients to share resources
Allows network to centralize functions and applications in one or more dedicated file servers (stability)
Remote Authentication Dial In User Service – used to authenticate remote users with user names and passwords
Downside…
-expensive, regularly maintenance

8. Point-to-Point Protocol
Point-To-Point Protocol (P.P.P.)
- establishes a direct connection
between to nodes
Validates users before allowing them access to server resources
Most common NOS used

9. Why P.A.P. is important..
The point of having a digital authentication password system is to secure sensitive information
You simply prompt a user to enter his/her id and password to gain system access.
P.A.P. transmits unencrypted American Standard Code for Information Interchange, or ASCII passwords over the network

10. Advantages & Disadvantages
Validates users before allowing access
Flexible Protocol
Password Strength
Lack of identity check
Shoulder Surfing
Plain text could be a ploblem

11. One & The Same?
Challenge Handshake Authentication Protocol seems to be an upgraded Password Authentication Protocol
It goes hand and hand with P.P.P.
Authenticates users to an entity with verification such as password
Many servers have replaced P.A.P. with C.H.A.P. because it’s deemed to be stronger
