A company disables cd drives for users; what defense strategy is this a part of?

Uniform protection applies identical security controls across all systems regardless of sensitivity, rather than creating segmented zones with targeted hardware restrictions.

Information-centric defense focuses on protecting data itself as it flows across systems, rather than restricting specific hardware peripherals at an endpoint.

The protected enclaves strategy segments an environment into isolated, secure zones where access to resources and hardware is tightly controlled and limited to what is necessary. Disabling removable media like CD drives enforces that boundary by preventing unauthorized data exfiltration or malware introduction within the enclave.

Vector-oriented defense identifies and mitigates specific attack pathways at a high level, and does not describe creating isolated zones with enforced hardware access controls.
