Firewall vs. Antivirus

As computer system has grown at another level, the security system must be proved because there are a lot of hackers all around the world. So computer programmers made systems like firewall and antivirus. These are best kind of software’s that can protect your system from virus. Question is what is a virus? Virus is a software that can destroy your system. So firewall and antivirus protect your system from virus. This article is all about the difference between firewall and antivirus. A firewall is a standard approach that protects computer systems from external threats. There are IP packets that come from the other computer network to our computer. The work of a firewall is to filter out the IP packets. These IP packets come from another system that infects our system. Firewall is one of the most important ways to protect the local system against the virus by using a firewall you can access the internet. The role of a firewall is to make sure that all the traffic that is going out and in the system go through the system. And if firewall check that some unauthorized traffic is coming then is protected our system making us warn. There are types of firewall that are packet filters that are also known as router and screening filters.

The main difference between firewall and antivirus is that a firewall is a barrier for the incoming traffic to the system whereas antivirus protects against the internal attack like malicious files. The purpose of both firewall and antivirus are same, but the working of both are different. Firewall work on inspecting the data flowing from the internet to computer on the other hand and antivirus emphasis on the malicious program inspection steps that includes detection, identification and removal. There are three processes of an antivirus that are detection, identification and removal of virus. In detection process software is aware of the malware attack and in this process, the infected file is located. In the identification process, it recognize which type of file is there, and in removal, it removes the infected file, and it also restores the original file. There are generations of antivirus that are 1st generation antivirus, 2nd generation antivirus and 3rd generation antivirus. 1st generation antivirus had simple scanners, and it scans the virus. 2nd generation antivirus uses a heuristic approach to detecting virus.

The job of pocket filters is to apply some rules that provide security of our system by detecting the virus and break the virus into tiny fragments. An application gateway is one other form of firewall that is also known as a proxy server. It decides the flow of the application level traffic. Then comes circuit gateway, it detects the virus in new connections and remote host. There are also some limitations of the firewall that is internal attacks are not blocked, and it cannot protect against malicious attack. An antivirus protect against the internal attack like malicious files. Antivirus is extremely good application software for virus protection. It is very important that we should protect our system from the virus as it is hard to prevent all the virus in the world.

What is Antivirus?

An antivirus protects against the internal attack like malicious files. Antivirus is extremely good application software for virus protection. It is very important that we should protect our system from the virus as it is hard to prevent all the virus in the world. There are three processes of an antivirus that are detection, identification and removal of virus.

Key Differences

  1. Firewall is a barrier for the incoming traffic to the system whereas Antivirus protect against the internal attack like malicious files.
  2. Firewall deals with internal threats whereas Antivirus deals with internal and external threats.
  3. Firewall inspect incoming packets whereas Antivirus inspect malicious software.
  4. Counter attacks are possible in firewall whereas Counter attacks are not possible in antivirus.
