An Introduction to IT Network Security

An Introduction to IT Network Security

Much sensitive information is held on pcs. Governments hold specifics of national security plus some personal information about members of the public. Businesses also hold important and confidential facts about pcs. People have data they will often not need other people to gain access to on the home computers, while bank details are yet another good demonstration of data that needs to be kept secure, either if held for the bank’s systems or by people in your house. All this implies that it is important that IT networks are kept secure.

Some people and groups attempt to gain access to secure information. This may be to commit fraud and gain financially or to reap the benefits of people and businesses in various ways. Terrorist groups may make an effort to gain confidential information that they’ll use, and some will hack into networks purely to cause havoc.

There are lots of stuff that can be done to ensure IT network security

The most obvious thing is by using simple antivirus software. There are lots of brands available and so they mostly perform a similar job, there is however more advanced antivirus software available. Antivirus software does exactly what it says about the tin, it prevents virus attacks.

Firewall systems are another frequently used security measure used for IT security. This is software that prevents unauthorized users by blocking them when they try and gain access. This is a must for highly confidential information, especially if it’s the kind of information that somebody may want access to for cynical reasons. The difference between firewall and antivirus software in that a firewall is like a wall from the computer and also the internet which intercepts security threats while antivirus software scans your personal computer for viruses then removes any situation that shouldn’t be there.

Other simple safety measures can also be taken

Other simple security measures may also be taken. This includes the usage of passwords. This may not be essential for family computer users if those residing in the property are the only ones who’d ever want to gain access. Businesses generally they make utilization of password protection though, to ensure only authorized users can gain access to the network.

Some businesses may have identical passwords for all those users although some may have separate usernames and passwords for all those. This allows these to have separate accounts, either with separate computers or separate accounts on the same network. This means that a variety of employees might be given the use of what they need, without having entry to data or documents not highly relevant to them. This makes it much easier to control who accesses what, plus a system that is especially used by companies who’ve much sensitive information.

All IT networks must have some kind of protection. Antivirus software is a must for those systems, including home computers. Whether or not a firewall or password protection is necessary depends on the confidentiality with the information stored.
