Software protecting individual devices from threats.

• A. Anti-Malware Software
• B. Detection
• C. Advanced Protection
• D. Personal Firewalls

Answer: (D)

A personal firewall provides on-device network protection by controlling what traffic can enter or leave a single computer. It runs on each device and monitors inbound and outbound connections, blocking unauthorized access, suspicious ports, or unusual application behavior. This directly shields the device from network-based threats and exploitation, which is precisely what “software protecting individual devices from threats” refers to.

Anti-malware software focuses on detecting and removing malicious software that has already reached the device, which is a different protective angle than controlling network access. Detection, as a term, describes finding threats rather than actively blocking them. Advanced protection is vague and could refer to a suite of features, but it isn’t as specific about guarding the device’s network perimeter as a personal firewall.
