Concept 4
Availability
Making sure systems and information are accessible when needed.
Availability means systems and information are accessible when needed.
The focus is:
“Can users access the system when they need it?”
Availability problems can happen because of:
- Power failures
- Hardware failures
- Ransomware
- DDoS attacks
- Accidental deletion
Ways availability is protected:
- Backups
- Redundant systems
- UPS power supplies
- Disaster recovery plans
