Keeping Data Secure

Measures that can be taken to keep data secure include:

  • making regular backups of files (backup copies should be stored in fireproof safes or in another building)
  • protecting yourself against viruses by running anti-virus software
  • using a system of passwords so that access to data is restricted
  • safe storage of important files stored on removable disks, eg locked away in a fireproof and waterproof safe
  • allowing only authorised staff into certain computer areas, eg by controlling entry to these areas by means of ID cards or magnetic swipe cards
  • always logging off or turning terminals off and if possible locking them
  • avoiding accidental deletion of files by write-protecting disks
  • using data encryption techniques to code data so that it makes no apparent sense
