The DoS function helps to detect and mitigates DoS attacks. These include flooding-type
attacks and vulnerability attacks. Flooding-type attacks attempt to use up all your system's
resources while vulnerability attacks try to paralyze the system by offending the
vulnerabilities of the protocol or operation system.
