keeping safe
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 |
