What is Data Security?
Data Security concerns the protection of data from accidental or intentional but unauthorised modification, destruction or disclosure through the use of physical security, administrative controls, logical controls, and other safeguards to limit accessibility. Ways of securing your data include:
Data Encryption – converting the data into a code that cannot be easily read without a key that unlocks it.
Data Masking – masking certain areas of data so personnel without the required authorisation cannot look at it
Data Erasure – ensuring that no longer used data is completely removed and cannot be recovered by unauthorised people.
Data Backup – creating copies of data so it can be recovered if the original copy is lost. General good practice, however, goes beyond these methods. Stringent processes should be put in place to cover all areas such as Password Policies.
