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
