Chapter 6: Telecommunications and Network Security - Intro

At our day in age, networking has become increasingly complex. A network used to have boundaries, but now, since we basically have a computer in our pocket that is capable of networking, there is no clear cut boundary of individual networks. As technology increases, so do threats from attackers. Because of this, the security professionals of today must understand networks on various levels. Telecommunications is the transmission of data through systems. The data can be carried through cables, or it can be wireless. There are two main organizations that govern telecommunications. The International Telecommunications Union (ITU) and the International Standards Organization (ISO).
