NIC

 

Network Interface Card. A board that provides network communication capabilities to and from

 

 

a computer system. Also called an adapter.

PAP

 

Password Authentication Protocol PAP is a security protocol that requires users to enter a

 

 

password before accessing a secure system. The user’s name and password are sent over the wire

 

 

to a server, where they are compared with a database of user account names and passwords. This

 

 

technique is vulnerable to wiretapping (eavesdropping) because the password can be captured

 

 

and used by someone to log onto the system.

password can decrypt the file.

 

 

 

Password

 

The encrypted password is no visible in the passwd file but stored in a shadow file that is only

Shadowing

 

readable by root. This prevents brute force attacks on the encrypted field to guess the password.

 

 

see e.g.: http://whatis.com/shadowpa.htm

 

 

 

Penetration

 

Gaining access to computers or networks by bypassing security programs and passwords.

 

 

 

Phreaking

 

Breaking into phone or other communication systems. Phreaking sites on the Internet are popular

 

 

among crackers and other criminals

 

 

 

Ping Attack

to the network repeatedly to slow it down. See also Denial of Service.

 

 

 

Pirate

Internet. In the internet underground it is known as Warez.

 

 

 

 

 

 

Plain Text

 

The opposite of Cipher Text, Plain Text is readable by anyone.

 

 

 

PNS

 

PPTP Network Server. A PNS must have IP connectivity.

 

 

 

POP

 

Post Office Protocol. This is a common protocol used for sending, receiving, and delivering mail

 

 

messages.

 

 

 

Port

 

An Internet port refers to a number that is part of a URL, appearing after a colon (:) right after

 

 

the domain name. Every service on an Internet server listens on a particular port number on that

 

 

server. Most services have standard port numbers, e.g. Web servers normally listen on port 80.
