Information Assurance - Network Connections - Physical Protection of Unclassified (NIPRNet) Network Devices such as Routers, Switches and Hubs
An XCCDF Rule
Description
<VulnDiscussion>Unclassified (NIPRNet) network connections that are not properly protected in their physical environment are highly vulnerable to unauthorized access, resulting in the probable loss or compromise of sensitive information such as personally identifiable information (PII) or For Official Use Only (FOUO).

Remediation - Manual Procedure
1. All network connections (on NIPRNet or other Unclassified Network under review) such as routers, switches, and hubs must be secured within a locked communications closet/room OR secured within a cabinet if the equipment is located in a room that is accessed by personnel other than designated network system administrators (e.g., SAs specifically designated to administer the network devices) and/or those with security management oversight (e.g., ISSM, ISSO, SM).
2. If other (authorized) personnel (e.g., other than assigned system/network administrators or security management) are permitted to have unimpeded access to network devices, this authorization must be approved in writing by the site commander/director or perhaps other significant staff officer with security oversight of information systems (e.g., J6, ISSM). The documentation must include a justification indicating why the unimpeded/unescorted access is mission essential. This access allowance must be limited to very few personnel and not provided for mere convenience.
3. The locked room or cabinet must be adequately secured so that it cannot be easily accessed without forcible entry.
