The firewall comes in handy when securing a network from various exposures to security threats. Some of these exposures include DDoS attacks and identity theft. The DDoS attack happens on a network, where the targeted server is flooded with fake traffics (Diovu & Agee, 2017), thus denying the legitimate user from accessing the server. However, this exposure is avoidable with a functional firewall, which blocks all fake traffics. Identity theft occurs when an adversary uses the information of another user to execute frauds on the internet. If the firewall is down, an attacker can access user information because there would be no filtering of packets.
