copies   of   the   certificate   of   degaussing   destruction should not accompany the media during transmittal. Performing Security Functions Security  functions  are  very  important  in  a  magnetic media  library,  not  only  for  classified  media  but  also  for any  material.  Data  has  value,  whatever  its  classification or use: Top Secret, Secret, Confidential, Privacy Act, For  Official  Use  Only,  or  Unclassified.  Applicable security instructions and procedures must be followed. Some of the tasks include the following: l l l l Storing  and  safeguarding  classified  media  and materials Maintaining security logs and library access lists Degaussing  and/or  destroying  classified  media and materials Changing lock combinations on doors, safes, and vaults Ensure  that  all  security  procedures  and  measures relating  to  the  library  are  understood  by  everyone connected  with  the  library,  especially  the  librarians. See   that   procedures   are   enforced.   This   includes controlling  entrance  (access)  to  the  library  spaces  (both on-site and off-site storage areas), as well as providing physical and administrative controls of the media. The librarians  must  ensure  proper  security  protection  is provided   for   all   magnetic   media   and   materials   in accordance  with  applicable  security  instructions  and procedures. This includes issuing, receiving, shipping, declassification, destruction, and disposal. MAGNETIC  MEDIA  ADMINISTRATIVE DUTIES Attention to administrative detail is a must. It will help  assure  that  media  are  properly  maintained  and ready  for  use.  Control  logs,  pass-down  log,  library listings,  and  reports  are  all  a  part  of  the  everyday administrative   functions.   Administrative   duties   and responsibilities include the following: .   Maintaining   tape   cleaning,   verification,   and degaussing logs l   Checking   magnetic   media   in   and   out,   using appropriate logs l Making entries in tape and disk control logs l Making entries in pass-down log l l l Labeling magnetic media Establishing  and  updating  current  and  history files Preparing  library  listings  and  reports  for distribution To   accomplish   this   task   requires   a   specially designed program that is able to read the internal label information that is stored on the magnetic media. The program  extracts  whatever  information  it  needs  to  build a record onto the library master file (or database file). Once a record is established, you can make changes or deletions  as  necessary. Most  AIS  installations  have  incorporated  or  are capable  of  installing  some  type  of  automated  tape library   control   (ATLC)   program.   Various manufacturers  supply  these  software  programs  for  their computing    systems. These   programs   provide   an automated  capability  for  preparing  various  user  and management  reports  to  assist  in  the  operation  and control of your installation’s magnetic media library. These reports reflect the current status of each tape reel, disk pack, and diskette in the library. You will find that various  manufacturers  give  different  names  to  their library accounting programs; however, the majority of these software systems accomplish the same functions. The names may change, but the game is the same. For this chapter, we use ATLC. A   good   ATLC   system   should   be   capable   of providing you with the library edit and error, reel master list,   application,   user/programmer,   media   to   be released,   library   maintenance,   off-site   storage,   and history  reports. 2-24
