• What method will you use to configure your VPN tunnels?
— The VPN Wizard using VPNC defaults (see
— The typical automated Internet Key Exchange (IKE) setup (see

• What level of IPSec VPN encryption will you use?
— DES - The Data Encryption Standard (DES) processes input data that is 64 bits wide,
encrypting these values using a 56 bit key. Faster but less secure than 3DES.
— 3DES - (Triple DES) achieves a higher level of security by encrypting the data three times
using DES with three different, unrelated keys.
• What level of authentication will you use?
— MDS: 128 bits, faster but less secure.
— SHA-1: 160 bits, slower but more secure.
