Telecommunications and network security use various mechanisms, devices, software and protocols that are interrelated and integrated.
Network security is one of the more complex topics in the computer field, mainly because so many components are involved. A network administrator or engineer must know how to configure networking software, protocols and services and devices; deal with interoperability issues; install, configure and interface with telecommunication software and devices; and troubleshoot effectively. A security professional must understand these issues and the vulnerabilities that can arise within the network.
