Types of Network Security

Do you know the types of network security tools that you can install on your system? Are your security tools doing the same job while leaving other areas open?

In the modern age, protecting our information has become a rather complex task that is far beyond the grasp of the ordinary computer user. Although there are a great number of products in the market today that increases security, each one cover a specific area of vulnerability. You need to know the types of security software so that you can cover all your bases without bugging your system down, as having two or more software do the same thing would take up a lot more resources.

Here are the types of network security software available in the market:

• Firewalls
• Antivirus
• Various other tools

Firewalls

Firewalls are basically traffic enforcers of the network. They decide which traffic is allowed to pass through and which ones should be blocked. In practice, firewalls need to be explicitly told that certain applications are allowed to access the Internet. All other connections are immediately blocked in order to prevent some programs from uploading your information to the Internet or downloading malicious scripts and programs that can harm your computer. It also automatically blocks all unsolicited communications from the Internet. This protects you against online attacks.

Antivirus

An antivirus no longer defends against viruses alone. Due to the rapid development of software and Internet threats, antivirus software are now able to screen out Trojans, worms, adware, and even spyware. A good antivirus software should provide you with real time protection, where it automatically scans the files that you attempt to open in order to know whether it is safe or not. Installing two or more antivirus software in a computer would often reduce their individual effectiveness as well as decrease the performance of your computer.

There are also a huge number of add-ons that can increase the security of your network. There are software that can tell you whether you are looking at a legit site or a fake one. It would immediately warn you so that you don’t enter your personal information into the fraudulent site. There are also network monitoring software that analyzes the network and detects whether an intrusion has occurred. The choice is all up to you. Aside from the first two, everything else is optional and should be considered on a case-to-case basis.
