What is Data Security?

Data security is a set of techniques and processes designed to ensure that bad actors are not able to gain access to sensitive or confidential data. This is done by ensuring that only authorized users can access and work with the information they have the right to access, and that they use secure and reliable methods. The most important aspects of this include authentication as well as authorization and granular role-based access control.

A solid data protection strategy provides business resilience, allowing the ability to continue operations and quickly recover from catastrophes or user error, application downtimes or malware attacks. It is also about ensuring that the backups of mission-critical data can be recovered in near-real time, and that backups are protected by physical and logical security protections.

Data security tools allow companies to monitor the location of their most critical information and observe how it is used. They can also track who has access to the data. They should be able to implement a variety of security measures, such as data encryption redaction, data masking as well as automated reporting for audits and compliance.

In addition, they should ensure data security at the source, whether it be in a database, cloud storage or file. This could include implementing zero-trust principles that rely on immutability, Quorum controls, and other security features that prevent any untrusted applications from altering or deleting your data. They can also use advanced security tools, for example behavioral analytics. This helps to identify normal patterns of data usage and alerts you to suspicious or risky behavior. They can also use machine learning technology and cognitive computing which mimics human thought to help prioritize the stream of security incidents and protect data in real-time.
