Welcome to the Communication & Network Security Skills Course & Certification Test
As the electronic storage of sensitive data becomes more common, the network security field continues to grow. Communication between networks must not only occur, but occur securely. Network protocols are in place to outline the rules that direct network communications between the networked computers, and it is through these means that computers with different operating systems and software are able to communicate with each other. Individuals in network security roles typically specialize in one type of system maintenance and work for organizations with particularly valuable data, such as investment firms, insurance companies and government agencies. Entrance into this type often requires higher education supplemented by certifications. Domain 4 of the CISSP exam focuses specifically on the basic network and telecommunications concepts. This includes, but is not limited to: secure network architecture design, secure network components, network attacks and secure communication channels. Being that telecommunications itself is such a broad topic, the communication and network security skill certification tests pulls the most important information for review. Topics span from network classes and their ranges, media used for transmission and weaknesses of Network Topologies. One important key concept, tunneling, is highlighted here, as well as a review of key OSI principles.
