A security administrator wants to deploy security controls to mitigate the threat of company employees' personal information being captured online. Which of the following would BEST serve this…

Spyware is a category of malware specifically engineered to monitor user activity, capture credentials, and exfiltrate personal information without the user's knowledge. Anti-spyware tools are purpose-built to detect, quarantine, and remove these threats. This directly addresses the scenario of personal information being captured online from company endpoints.

Antivirus software primarily targets traditional malware such as viruses and worms and may not adequately detect or remediate the full range of spyware designed for stealthy data capture.

A host-based firewall controls inbound and outbound network connections but cannot detect or remove spyware that is already installed and operating on the system.

A web content filter blocks access to categories of malicious or unauthorized websites but does not remove existing spyware or prevent already-installed spyware from exfiltrating data.
