NOTE

IMPORTANCE OF DATA SECURITY

Data security is critical for most business and even home computer users. Client information, payment information, personal files, bank account details- all this information can be hard to replace and potentially dangerous if it falls into the wrong hands. 

Data lost due to disaster such as a flood of fire is crushing, but losing it to hackers or a malware infection can have much greater consequences.

 

MAJOR THREATS TO DATA SECURITY

1. Accident can happen due to human error or software/ hardware error.
   b. Hackers could steal vital information and fraud can easily be perpetrated.
   c. Loss of data integrity.
   d. Improper data access to personal or confidential data.
   e. Loss of data availability through sabotage, a virus , or a worm.

 

INTEGRITY CONTROLS

BACKUPS
This is the process of copying and archiving of computer data so it may be used to restore the original after a data loss event.

Backups have two distinct purposes.

1. The primary purpose is to recover data after its loss, be it by data deletion or corruption.
2. The secondary purpose of backups is to recover data from an earlier time, according to a user-defined data retention policy, typically configured within a backup application for how long copies of data are required. Backup is just one of the disaster recovery plans.

 

APPLICATION SECURITY

Application security is the use of software, hardware and procedural methods to protect application from external threats.
