What is Data Security?
Data security refers to a set of methods and technologies that are designed to ensure that bad actors are not able to gain access to sensitive or confidential data. It is important to ensure that only authorized users have access to and work with the data they are permitted to use. They should also be able to do this in a secure and dependable method. The most crucial aspects of this include authentication, authorization and granular roles-based access control.
A well-constructed data protection strategy is crucial to business resilience. It allows businesses to continue operations, and quickly recover from user error and disasters as well as application outages or malware attacks. It is also about ensuring that the backups of mission-critical data are recovered in near-real-time, and that the backups themselves are protected with physical and logical security controls.
Data security tools allow organizations to track the location of their most crucial data and track how it is being used. They can also see who has access to the data. They should be able a variety protections including encryption of data as well as redaction of data and automated reporting.
They should also protect data at the source – whether it’s in a data base or file, or in a cloud storage system. This could include implementing zero trust principles that rely upon immutability, quorum controls, and other security measures to stop any unauthorised software from altering or deleting your personal information. Additionally, they can use advanced security tools, for example behavioral analytics. This identifies normal patterns of data usage and alerts you to abnormal or risky behavior. They can also use cognitive computing and machine learning which mimics the human brain to help identify security threats and protect data real-time.
