How to Increase Computer Network Security

Computer network security is a branch of computer technology which individual users and especially large organizations have to deal with regularly. The objective or purpose of computer network security is to protect vital and valuable information from the occurrences of natural disaster, corruption or hacking. At the same time, it involves providing access to specific and limited users for the purpose of sharing information.

It’s an age where computer hackers are always on the lookout for accessing valuable or confidential information for their own benefits or just for the sake of fun. However there are varied steps one may follow to avoid such leakage of their personal files and programs.

The most important and foremost thing people need to do is install an antivirus software which can keep updating itself automatically, whenever new versions of the software are available. Now there are many such programs available which one may not need to run manually. Antivirus programs like Avast, McAfee, Norton, KasperSky and NOD 32 need to be set by the user so that they continuously search for unwanted elements that can access the system. Apart from this, one must ensure that the virus definitions are checked manually to maximise security. Spyware tools can also be run regularly. The difference between the latter and the antivirus programs is that spyware are more manual and do not run in real time. So the users need to manually launch the application and set it up so that it can search for existing unwanted applications.

A computer firewall needs to be enabled so that it can prevent malicious software from accessing the system. The firewall’s database recognizes the data that are safe and only these are allowed to make modifications or updates in the system.

The operating system needs to be updated at regular intervals to make sure that an expired or unavailable version isn’t being used, because otherwise it may make the computer prone to common and emerging threats. An up to date system is very likely to avoid outside third parties from intruding.

Many computer users like to exercise their freedom while downloading information from the Internet. However, it is likely that many games or audio/video files available on some websites may be corrupt. People often check to make sure that such files are free from spam, by performing a virus check through anti-virus programs already there in the system. However, the trouble may be avoided if users rarely install such programs and make their Operating Systems more restrictive.

Another tool that has become quite useful in the network world is a honey pot. It works as a trap which is set to detect and counteract attempts of malicious spam content that attacks a system. It provides bulk spam capture and is a powerful measure to find out the e-mail addresses spammers use.
