NTLM also has some security shortfalls that Kerberos does not. Kerberos and NTLM are described in depth in Chapter 7.
- IP Security
TCP/IP’s use has become widespread. While TCP/IP provides enormous benefits over other network protocols, it is not desirable from a security standpoint. Data sent over a network with this suite of protocols ...
