Description
This requirement addresses the confidentiality and integrity of system information at rest (e.g., network device rule sets) when it is located on a storage device within the network device or as a component of the network device. This protection is required to prevent unauthorized alteration, corruption, or disclosure of information when not stored directly on the network device. Files on the network device or on removable media used by the device must have their permissions set to allow read or write access to those accounts specifically authorized to access or change them. Note that different administrative accounts or roles will have varying levels of access. File permissions must be set so that only authorized administrators can read or change their contents. Whenever files are written to removable media and the media removed from the device, the media must be handled appropriately for the classification and sensitivity of the data stored on the device.
