There are a variety of data security, however the most important ones include:

Authentication is the process of verifying whether or not the individuals who have access to your data are actually who they claim be. This can be done using passwords, multifactor authentication, and other identity verification tools.

Encryption – The process of changing information into an unreadable format so only those with the necessary keys can access it. This protects sensitive information in transit and at rest such as files, databases, and email communications.

Monitoring – The practice of blocking malicious actors from accessing or transferring data from the network of your company by blocking or intercepting them at the gateway. This can include data loss prevention (DLP) technology, encryption and educating employees on the best practices.

Backups – The possibility of quickly and securely restoring data in the event of the system fails or a disaster, cyberattack, or data breach happens. This can be accomplished by creating a backup of the data in a different format or by storing it in the cloud.

Data minimization is the process of only storing information that is necessary to your business. This helps reduce your vulnerability by decreasing the number of victims for hackers. This can reduce storage costs, and can prevent bloat which could result in compliance issues.
