Telecommunications and Network Security is the lengthiest domain of CISSP. It emphasizes the concepts of networking -- OSI and TCP / IP models -- explaining each layer in detail; highlighting the technologies and their implementation. The domain discusses the following main concepts:
Physical: Network Topologies, Transmission Media, Communication Technology, Attacks
Data-Link: Technology, Encryption, Risks and Attacks
Network: WAN Technologies, Tunneling, Risks and Attacks
Transport: Technology, DoS Attacks, Remediation
Session: Technology and Implementation, Directory Services, Access Services
Presentation: Concepts, Technology and Implementations, Encryption
Application: Technologies, Data Exchange Services, Administrative Services
The domain also discusses different types of Firewalls and their architectures in detail. Different security protocols and methodologies like PGP, IPSec, SSL (VPN) etc. are also discussed in Network Security portion of the domain. Telecommunications and Network Security domain keeps on evolving with latest technologies arising and gives an overview of them as well, for example, Unified Threat Management.
