The administrator receives a call from an employee named Joe. Joe says the Internet is down and he is
receiving a blank page when typing to connect to a popular sports website. The administrator asks Joe to try
visiting a popular search engine site, which Joe reports as successful. Joe then says that he can get to the
sports site on this phone. Which of the following might the administrator need to configure?
The access rules on the IDS
The pop up blocker in the employee’s browser
The sensitivity level of the spam filter
The default block page on the URL filter
A URL filter is used to block access to a site based on all or part of a URL. There are a number of URL-filtering
tools that can acquire updated master URL block lists from vendors, as well as allow administrators to add or
remove URLs from a custom list.
A: An intrusion detection system (IDS) is an automated system that either watches activity in real time or
reviews the contents of audit logs in order to detect intrusions or security policy violations.
B: Pop-up blockers prevent websites from opening further web browser windows without your approval.
C: A spam filter deals with identifying and blocking/filtering/removing unsolicited messages.
