There are a myriad of types of data security, but the most important ones are:

Authentication -- The method of confirming that the people who have access to your data are who they claim to be. This includes using passwords, multifactor authentication, and other identity verification tools.

Encryption -- The process of changing information into an unreadable format, so only those with the appropriate keys are able to view it. This safeguards sensitive data at rest and during transit such as databases, files and email communications.

Monitoring - The practice that prevents malicious actors from having access to or moving data out of your organization's networks by blocking or interception at the gateway. This can include data loss prevention (DLP) and encryption and training employees on the best practices.

Backups -The ability to quickly and safely restore data in the event of a system malfunction such as a cyberattack, disaster, or data breach. This can be accomplished by generating a data copy in a different format or by placing data in the cloud.

Data minimization -- The process of only storing the amount of data needed by your business. This minimizes your vulnerability as hackers will have fewer targets to target. This helps reduce the cost of storage, and can prevent bloat which could lead to compliance issues.
