Firewall and antivirus are the mechanisms to provide security to our systems. Although the vulnerabilities are different in both cases. The major difference between them is that a Firewall acts as a barrier for the incoming traffic to the system. Conversely, Antivirus protects against internal attacks like malicious files, etc.
Both Firewall and Antivirus function on different approaches like Firewall emphasizes on inspection of the data flowing from the internet to computer. In contrast, an Antivirus emphasizes the malicious program inspection steps such as Detection, Identification, and Removal.
Differences between Firewall and Antivirus
|It is a security network designed to protect computer systems and networks from malicious attacks.||It is a software utility program designed to protect a system from internal attacks from viruses, trojan horse, spyware, etc.|
|The general term used for a firewall is “packet filter” because it filters any incoming data packets for suspicious contents.||Antivirus identifies and corrects any weaknesses found in the computer system.|
|The main purpose of a firewall is to monitor network traffic and restrict any unauthorized entry||The main function of an antivirus is to scan, detect, prevent and remove any existential threat to the computer system|
|It works at a network protocol level to safeguard against any unwanted intrusion||An antivirus will only scan for any harmful programs that are present in the system such as viruses, worms, Trojans, etc|
|One of the limitations of a firewall is that it cannot block any internal attacks and also those attacks that bypass its network coverage||One of the limitations of antivirus is that it is cannot check read-only files.|
|DEC SEAL was the first commercially viable firewall program that came out in 1992. Its creation was spearheaded by American computer scientists Brian Reed and Jeff Mogul.||The first documented removal of a computer virus was by an actual antivirus software was in 1987 when a German computer security expert, Bernard Robert Fix, created a program to remove a virus that had infected files in a DOS-based system|
