If you are a victim of Denial of Service (Dos) then what would you do?The function of a denial of service attack is to flood its target machine with too much traffic and prevents it from being accessible to any other requests or providing services.
a. To prevent DoS attacks firewall can be configured as a relay; in this approach the firewall responds on behalf of the internal host. During the attack, the firewall responds to the SYN sent by the attacker; since the ACK never arrives, the firewall terminates the connection.
b. By Keeping protocols and Antivirus software up-to-date, we can prevent to be a victim of DoS. A regular scanning of the machine is also necessary in order to detect any “anomalous” behavior.
