5. Using software to protect systems

A business can also use software to help protect their systems.

Some of these methods include:

  • Data encryption - data is 'scrambled' before being transmitted through a network. Only the authorised recipient has the 'key'.
  • Firewalls - software to block access from outside (and to prevent data being sent out in some cases)
  • Activity or Audit logs - to track who has been doing what on the system
  • User IDs and Passwords
  • Access rights
