11.8 Security of Data

Security of data is all about protecting data integrity from threats whether the threats are deliberate or accidental, internal or external. You *should* have covered a bit of this in ICT1 (10.8 Malpractice and Crime) so dig out your old notes!
 

• Understand the importance of and the mechanisms for maintaining data security. Describe the distinction between security and privacy
   

• Understand simple processes that protect the integrity of data against malicious or accidental alteration; standard clerical procedures, passwords, levels of permitted access, write protect mechanisms, backup procedures, restoration and recovery procedures
   

• Understand the need for regular and systematic backup and procedures for recovery
