It is merely the process of determining if the credentials given by a user or another system (such as a username and password) are authorized to access the network resource in question. When you log in with your username and password, the system will attempt to authenticate that username and password. If it is authenticated, you will be granted access. Another crucial safeguard is auditing, which is the process of reviewing logs, records, and procedures to determine if these items meet standards.
This understanding of networks and the Internet will be crucial to your comprehension of later topics presented in this book. We will begin by examining the basic technologies, protocols, and methods used for networks and the Internet to communicate. Then we will take a look at the history of the Internet. This information forms the background knowledge you will need to understand various cyber attacks, and how they are defended against. In the exercises at the end of the chapter, you will be able to practice using some protective methods, such as IPConfig, tracert, and ping.
However, even wireless communication relies on a physical device to transmit the data. There is a card in most modern computers called a network interface card, or NIC. If the connection is through a cable, the part of the NIC that is external to the computer has a connection slot that looks like a telephone jack, only slightly bigger. Wireless networks also use a NIC; but rather than having a slot for a cable to connect to, the wireless network simply uses radio signals to transmit to a nearby wireless router or hub.
