What term means removing or severely restricting communications paths to a particular device or system?

• A. Isolation
• B. Antivirus
• C. Web filtering
• D. Full disk encryption

Answer: (A)

Isolation means removing or severely restricting communications paths to a device or system. In practice, this involves disconnecting the device from the network, disabling its network interfaces, or enforcing rules that limit its connectivity so it can’t reach other systems or services. This containment approach is widely used in incident response to stop the spread of malware and to prevent an affected system from being used as a stepping stone to attack others, sometimes even creating an air-gap where the device has no network access at all. Antivirus isn’t about cutting off communications; it’s a security tool that detects and removes malware on a host. Web filtering controls what websites can be accessed, but it doesn’t completely isolate a machine from all network paths. Full disk encryption protects data at rest on the storage device, not the network connectivity of the system.
