What is Data Security?

Data security consists of a range of technologies and processes that block bad actors from accessing sensitive or confidential information. It is essential to ensure that only authorized users have access to and can work with data that they are allowed to use. They should also perform this in a safe and dependable way. The most important aspects of this are authentication, authorization and granular roles-based access control.

A solid data protection strategy helps to ensure business resilience, giving a way to continue operations and quickly recover from catastrophes, user errors, application downtimes or malware attacks. It also involves ensuring that backups of data that are mission-critical can be recovered in near-real time, and that the backups themselves are protected with physical and logical security measures.

Data security tools permit organizations to view the location of their critical data, how it is being utilized and who is accessing it. They should be able to put in place various protections, including encryption of data, data masking, redaction and automated reporting.

Additionally, they should provide data protection at the source, whether it be in a cloud storage, or file. This can include implementing zero-trust principles that rely on immutability Quorum controls, and other security features that prevent unauthorized applications from modifying or deleting your data. They can also make use of advanced security tools, like behavioral analytics. This identifies normal patterns of data usage and alerts of abnormal or risky behavior. They can also use machine learning technology and cognitive computing, that simulates human brain activity to help prioritize the stream of security events and secure data in real time.
