An administrator wants to block users from accessing a few inappropriate websites as soon as possible. The existing firewall allows blocking by IP address. To achieve this goal the administrator will need to:
A.
upgrade to a DNS based filter to achieve the desired result.
B.
use the company AUP to achieve the desired result.
C.
upgrade to a URL based filter to achieve the desired result.
D.
upgrade to a text based filter to achieve the desired result.
URL filtering allows you to control access to Internet websites by permitting or denying access to specific websites based on information contained in an URL list. You can maintain a local URL list on the router, and you can use URL lists stored on Websense or Secure Computing URL filter list servers. URL filtering is enabled by configuring an Application Security policy that enables it.
