Which term best describes the protection of devices connected to a network?

• A. Endpoint Security
• B. Patch Management
• C. Full Encryption
• D. Ransomware

Answer: (A)

Endpoint security focuses on securing the devices that connect to a network, such as laptops, desktops, and mobile devices. It is the set of protections applied at the device level to prevent threats from entering or spreading across the network. This includes defenses like antivirus/anti-malware, host-based firewalls, device control, and often measures such as EDR and, where appropriate, encryption and patch management. Describing protection for those connected devices is precisely what endpoint security is all about, making it the best fit for the question.

Patch management is about keeping software up to date to fix vulnerabilities, which is a part of security practice but not the overall term for protecting devices themselves. Full encryption protects data, not the devices’ ongoing security posture. Ransomware is a type of threat, not a protection approach.
