Describe the two IPSec modes of operation.
What will be an ideal response?
IPSec works in two different modes: transport mode and tunnel mode. Transport mode is used to provide secure communications between hosts over any range of IP addresses. Tunnel mode is used to create secure links between two private networks. Tunnel mode is the obvious choice for VPNs; however, there are some concerns about using tunnel mode in a client-to-site VPN because IPSec by itself does not provide for user authentication. However, when combined with an authentication system like Kerberos, IPSec can authenticate users.
