The fact that there are always some malicious people that will try to manipulate and misuse a given system cannot be refuted. This calls for the administrators of such a site to devise ways in which to keep off such misuse. This describes what network security is all about.
Networks are set up by individuals, businesses, companies and other organisations. There are those that consider it relevant to have some interactive avenue with their clients. With such kind of formality, it is very crucial that all the operations taking place within the networks should be monitored and controlled.
The administrator is thus put in a position whereby they can protect the functions that take place within their established site. In essence this enables them to dictate what content should be operated on their site in a way. No other external users can be able to include other unsupported information.
The use of a unique username and a password is one of the most basic ways that most of the people use to enhance security for their networks. The user is provided with a very unique identification tag that will distinguish them from any other users in the whole system. This is very crucial.
Such kind of verification is considered as a one-factor method since the user only performs one action. With a two-factor process, there will be the additional use of something that the user has. The three-factor will include a thing with the user as well as something within the user such as fingerprints.
The security process works by virtue of some existing firewall that determines whether information will be accessed or not. When the user provides their identification details, the firewall will either approve and allow access or otherwise reject. Good to note is that not all the information will be availed to the user and there will be some sorting on what information is to be availed to whom.
Another aspect not to be overlooked is that the firewall will not detect all the malicious items within the traffic of the networks. There may be some other leakages that will miss out on the detection of the firewall; such will include Trojans and the computer worms. In this case, the administrator will be forced to employ other mechanisms such as the use of antivirus software and other systems.
It is very important to ensure that your network is protected. This is in all the aspects possible from any persons that are not allowed to have its access. This issue of network security can only be most comfortably handled by having proper know how thus ensuring proper working of the system.
