Deliberate Threats
Threats that are created to cause loss or damage to the data or information system.
- Malware
- Hacking
- Phishing
- Denial of Service (Ddos) Attacks

Physical Security Controls
- Zone Security Strategies: Involves breaking down network into discreate sections or zones (Damage caused by security threats can be limited to one zone and the zone can be blocked off)
- Barrier techniques: Fences, gates, bars on windows, doors with locks using swipe cards, password touch pads, active badges, voice recognition and biometrics, guards, CCTV
- Biometrics: unique physical attribute of an individual e.g. fingerprint
- Uninterrupted Power Supply (UPS): Battery backup, provides backup power when your main power cuts out; stops everything from cutting out at the same time
Physical Procedures
Backups

* Economic – time and cost
* Technical – speed of processing, capacity, availability of equipment, compatibility and security
* Social – level of expertise of user
* Legal – ownership and privacy of data requirements
* Usability – usefulness and ease of use of a solution
Validation
Checks that data is reasonable and complete
- Existence check
- Data type check
- Range check
Verification
Proofreading and checking against the source data
Archiving
