Staying Safe

Staying Safe

1. Keeping Data Secure

   • 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

2. Online Banking

   • you will notice that the http in the address bar has changed to https.
     • This indicates that a secure connection between your computer and the bank's computer has been established
       • Data sent between the two computers is encrypted so that anyone trying to intercept your data will receive meaningless data. The data can only be decrypted into readable data by using a key that is known only to the two computers - yours and the bank's.

3. Data Security

   • Data security is about keeping data safe. Many individuals, small businesses and major companies rely heavily on their computer systems. If the data on these computer systems is damaged, lost, or stolen, it can lead to disaster.
