Security could be wide concern for everyone when we talk about network and Intranet or VPN. IP Sec (Internet Protocol Security Protocol) is widely used and proven method to guarantee to protect the data being read, intercept or otherwise interfered.
IP Sec has two modes of encryption: (a) Tunnel - encrypts the header and the payload. (b) Transport - encrypts only the payload.

AAA Servers (authentication, authorization and accounting servers) are used to increase security in a remote-access environment and will carry out the following checks:

• Who the user is.
• What the user is permitted to do.
• What the user is actually doing.
