CISSP: Telecommunications and Network Security



Telecommunications is the electrical transmission of data between systems, whether it is analog, digital, or wireless communication. The data can be converted (digital to analog), compressed, encrypted, and multiplexed many times taking on different forms such a datagram(UDP is one style), packet (IP), cell (ATM), and so on. When it all works together the result is awesome.


As data travels around a network (telecomm or otherwise) it must adhere to a set of rules to be transferred correctly and semi-efficiently.



The most common and largest set of rules is known as the Internet. The Internet is based upon the TCP/IP protocol, which adheres to the world standard ISO layer model.
 


 
This domain includes:
  • Network architecture and design
  • Communication channels
  • Network components
  • Network attacks
Here are some videos which explains Telecommunications and Network Security  well:
