Designing Network Security
Compared to the first version of this title, the second version offers information regarding leading edge technologies such as Voice over IP (VoIP) and wireless networks. Another topic covered in the second version is Virtual Private Networks (VPN). Making the second version of this title a very well rounded resource. Another new chapter in the second addition is on Routing Protocol Security. The Routing Protocol Security chapter has some good information on several of the widely deployed Interior Gateway Protocols such as RIP, EIGRP and OSPF. The chapter covers information mostly on the authentication pieces and fundamental rules of each routing protocol and not much more.
I found the small section on BGP in the chapter to be a little sparse and expected BGP to be covered in a bit more detail. Nonetheless, is does mention briefly, some of the challenges with BGP and a few of the proposed successors of the BGP protocol such as S-BGP and SoBGP.
This is an all-a-round good reference for network security.
