- Contingency
- Redundant Server - 2What are the two general threats to a computer system?Internal Threats
External Threats - 3What types of actions fall under these two threats?Internal - Accidental damage, disgruntled employees
External - Hacking, Malware, Natural Disasters - 4What is hacking?Gaining unauthorised access to a computer/network
- 5What are the three 'hats' of hackers?- Black hat

- Tracks programs
- Identity theft
- Vectors -> virus - 12What is scareware?- Pop-ups e.g. "system is compromised"

- 16What is malicious damage?Damage which is caused on purpose
- 17What are the methods that can be used to prevent these types of damage?- Company policy
- Strong passwords
- Levels of access
- Locking stations when out-of-use
- Destroying hard copies of files - 18What are levels of access?Users have varying access:
- Some can only read files
- Some can read and write
- Others can't see the files at all
Less chance of damage ∵ fewer people have access - 19What is a contingency plan?- Preparation for data loss
- Help recover after an attack - 20What are the methods used in a contingency plan?- Server backups
- Redundant servers
- Key personnel transfer - 21How does a server backup help recover after data is lost?- Data <-- backup
- Backup regularly - 22What is a redundant server and how does it help recover after data is lost?A spare server that is kept off-site and offline
Help by:
- Turned on after the attack
- Keeps business flowing
- Limits downtime - 23What is key personnel transfer and how does it help recover after data loss?Moving key workers to a new site
Helps by:
- Key workers -> server
- Maintain server
