We are going to be discussed about Telecommunications and Network Security. Telecommunications and Network Security is considered to be one of the ten domains of the CBK (Common Body of Knowledge) for the CISSP Certification Exam.
In today’s global marketplace, the ability to communicate with others is considered to be a mandatory requirement. The Telecommunications and Network Security domain is going to be encompassing the network structure, transport formats, transmission methods, and security measures utilized so as to maintain the integrity, availability, authentication, as well as confidentiality of the transmitted information over both public and private communication networks. So if you wish to clear the CISSP certification, you need to learn this domain and if you wish to gain more knowledge, you could have it through the prep courses offered by SPOTO.
The candidates would be anticipated for representing an understanding of communications and network security as it would be related to voice communications; data communications in terms of local area, wide area, as well as remote access; Internet or Intranet or Extranet in terms of Routers, Firewalls, and TCP/IP; and communications security management and techniques in terms of detective, preventive, and corrective measures.
Key Areas of Knowledge
- Establishing secure data communications
- Understanding secure network architecture and design
o OSI and TCP/IP models
o IP networking
- Securing network components
o End-point security
o Filtering devices (e.g., firewalls, proxies)
o Hardware (e.g., modems, switches, routers)
o Transmission media
- Establishing secure communication channels
o Multimedia collaboration (e.g., remote meeting technology, instant messaging)
o Remote access
o Virtual private networks (VPN)
o Voice over IP (VoIP)
- Understanding network attacks
The Telecommunications and Network Security domain would be including the constructions, security measures, transport formats, as well as transmission methods that provide confidentiality, integrity, availability, as well as authentication for transmissions over public and private communications media and networks. This domain is the information security domain that would be concerned with protecting data, and voice, communications and ensuring:
- Confidentiality which would be making sure that only those who are supposed to access the data would be able to access it. Confidentiality is considered as the opposite of disclosure.
- Integrity which would be making sure that the data hasn’t been changed by accident or malice. Integrity is the opposite of alteration.
- Availability which would be making sure that the data is considered as accessible when and where it is needed. Availability is considered to be the opposite of destruction.
The Telecommunications Security domain of information security would also be apprehensive with the prevention and detection of the misuse or abuse of systems, which poses would be a threat to the tenets of (Confidentiality, Integrity, and Availability.)
The agenda of the same would be as follows:
We would be starting with the understanding of Objectives set by (ISC)2 for this domain. This would be again followed by understanding the concept of Secure Secure Network Design and Architecture.
Networking components are going to be discussed next with the Emphasis on its Security. Securing Communication Channels would be discussed next.
According to the (ISC) 2 Bulletin Candidate Information, a CISSP candidate is considered to be expected to demonstrate an understanding of communications as well as network security as it would be relating to data communications in LAN’s (local area networks) and WAN’s (wide area networks); remote access; Internet, intranet as well as extranet configurations, use of firewalls, network equipment, and protocols like the TCP/IP, VPN, and techniques so as to prevent and detect network-based attacks.
Going through all this information is very hard and to retain it in mind, it is much harder. So if you wish to have good preparation courses for the CISSP exam, you could have it by joining the courses offered in SPOTO.
