Safe data storage is a critical aspect of any IT strategy. It involves identifying, mitigating and preserving sensitive or confidential data available to those who need it.
The most crucial aspect of secure data storage is to ensure that the physical security of the data is as high as it is possible to be to stop the entry of unauthorized individuals through external or internal attackers. This includes using access control based on role to limit the extent and scope of access privileges a user has. It also involves the use of a system to record the removal and re-entry of records to make sure that data is not deleted or retrieved without authorization.
A strong password is an additional crucial aspect of secure data storage. Passwords should be difficult to guess and should not be shared or put on desks where they will easily be discovered.
Immutable storage is an excellent method of preventing bad actors from altering the data on disks, SSDs, and the cloud. This is achieved through a combination of the use of encryption and other security controls like traffic profiling or machine-learning-based security systems that prevent data loss.
Of course the fact is that no data storage system is impenetrable however the goal should be to make it as hard to hack as it is so that the cost to a hacker is greater than the value of the compromised data. A comprehensive IT infrastructure to ensure secure data storage should include regular updates and patches for all operating systems and software, as well as a solid security framework for the network which blocks unauthorised users from accessing storage systems and redundant storage to guard against hardware failure or natural disasters.
