  PE-04: Access Control for Transmission Medium  

base control objective:
The organization controls physical access to information system distribution and transmission lines within organizational facilities.

supplemental objective information:
Physical protections applied to information system distribution and transmission lines help prevent accidental damage, disruption, and physical tampering. Additionally, physical protections are necessary to help prevent eavesdropping or in transit modification of unencrypted transmissions. Protective measures to control physical access to information system distribution and transmission lines include: (i) locked wiring closets; (ii) disconnected or locked spare jacks; and/or (iii) protection of cabling by conduit or cable trays.

enhancements to the base objective:

(1) None.
