Advantages and disadvantages of firewall in computer network
Answers
Answer:
•Advantages of Firewall Technology
~It effectively isolates your computer from external threats. According to various studies, Windows computers which did not have a firewall activated upon connecting to the internet were exposed to various forms of cyber threats within a matter of minutes.
•Disadvantages of Firewall Technology
~Although firewalls are capable of blocking access to human intruders, they cannot defend against threats posed by malware, such as viruses.
~If a user on your network inadvertently opens an email containing malware, they may still be able to infect your infrastructure regardless of your firewall. With that in mind, it could be argued that one of your firewall's disadvantages is that it cannot exist alone as a comprehensive security tool. Thinking of your firewall as a service rather than a whole defense system is pragmatic and necessary.
