What is Data Security?
Data security is a collection of methods and technologies that are designed to prevent bad actors from gaining access to sensitive or confidential data. It is essential to ensure that only authorized users have access to and can work with the data they are allowed to use. They should also do so in a secure and safe way. The most important aspects of this are authentication, authorization and granular roles-based access control.
A solid data protection strategy is crucial to business resilience. It helps businesses continue their operations and recover quickly from the effects of user error and disasters and application failures, as well as malware attacks. It is also important to ensure backups of mission-critical data can be retrieved quickly and are secured with physical and logical security measures.
Data security tools allow organizations to track the whereabouts of their most vital data and see how it is used. They can also see who has access to the data. They should be equipped to implement a range of protections, including data encryption redaction, data masking and automated reporting for audits and compliance.
They should also protect data from the beginning – whether it’s in a data base or file, or a cloud storage system. This may include the implementation of zero trust principles that are based on quorum controls and other security measures to stop malicious applications from changing or deleting your data. They can also use advanced security tools, for example behavioral analytics. This is a method of identifying normal patterns of data usage and alerts you to dangerous or unusual behavior. They can also employ cognitive computing and machine learning, which simulates the human mind to help prioritize security events and safeguard data real-time.
