By Jason Andress
In the world of network security, we may face any of a number of threats. These may take the form of configuration issues on infrastructure or network-enabled devices, outages of power or communications lines, or more direct threats from attackers. As many people throughout the world are now heavily dependent on computers and networks to conduct business and manage their personal lives, loss of network connectivity and access to the services that depend on these networks can be extremely disruptive, at the least.
In this article, we will discuss some of the mechanisms that are used to protect networks, items of security infrastructure and devices put in place to increase stability and security, and measures taken to protect the traffic moving over these networks. The article may seem a little less technical for the more advanced ethical hacking crowd, but as this column moves forward, a base level of knowledge is a good thing to reinforce before moving on to higher level topics and even a new contest next month (wink wink nod nod).
