Which of the following will allow Pete, a security analyst, to trigger a security alert because of a tracking cookie?

A network-based firewall filters traffic based on IP addresses, ports, and protocols at the network perimeter and cannot inspect or alert on tracking cookies stored in the browser.

Anti-spam software filters unsolicited email messages and does not scan local browser storage or detect tracking cookies.

A host-based firewall controls inbound and outbound network connections on a host but does not analyze browser cookie storage for tracking activity.

Anti-spyware software specifically targets potentially unwanted programs including tracking cookies, adware, and spyware that covertly collect user information. It inspects the local system and browser storage for known tracking cookie signatures and behavioral patterns, generating security alerts when they are found. This is the correct tool category because tracking cookies are a spyware-class threat, not a network-layer or spam threat.
