There are a myriad of types of data security, but http://www.mydigitalbusinessblog.com the most important ones are:

Authentication is the process of confirming whether or not the people who have access to your data are really who they claim to be. This may include using passwords, multifactor authentication and other identity verification tools.

Encryption is the process of converting information to an unreadable format so only those with the necessary keys can access it. This safeguards sensitive data at rest and during transit, such as databases, files and email messages.

Monitoring is the practice of blocking malicious actors from gaining access to or moving data out of your network by blocking or intercepting them at the gateway. This can include data loss prevention (DLP), encryption, and educating employees about best practices.

Backups — The ability to quickly and securely restore data in the event of a system failure, disaster, cyberattack or data breach. This can be done by creating a data copy in a different format or by keeping data in the cloud.

Data reduction — The process of only keeping the amount of information that is essential to your business. This reduces your vulnerability because hackers will have fewer targets to attack. This lowers the cost of storage and helps prevent bloat that could lead to compliance issues.
