Secure Sensitive Data Configuration Files 19 Configuration Files A configuration file contains the configuration of a device. A device has a Running Configuration file, a Startup Configuration file, a Mirror Configuration file (optionally), and a Backup Configuration file. A user can manually upload and download a configuration file to and from a remote file-server. A device can automatically download its Startup Configuration from a remote file server during the auto configuration stage using DHCP. Configuration files stored on remote file servers are referred to as remote configuration files. A Running Configuration file contains the configuration currently being used by a device. The configuration in a Startup Configuration file becomes the Running Configuration after reboot. Running and Startup Configuration files are formatted in internal format. Mirror, Backup, and the remote configuration files are text-based files usually kept for archive, records, or recovery. During copying, uploading, and downloading a source configuration file, a device automatically transforms the source content to the format of the destination file if the two files are of different formats. File SSD Indicator When copying the Running or Startup Configuration file into a text-based configuration file, the device generates and places the file SSD indicator in the text-based configuration file to indicate whether the file contains encrypted sensitive data, plaintext sensitive data or excludes sensitive data. • The SSD indicator, if it exists, must be in the configuration header file. • A text-based configuration that does not include an SSD indicator is considered not to contain sensitive data. • The SSD indicator is used to enforce SSD read permissions on text-based configuration files, but is ignored when copying the configuration files to the Running or Startup Configuration file. The SSD indicator in a file is set according to the user's instruction, during copy, to include encrypted, plaintext or exclude sensitive data from a file.
