Data security is the protection of data both physical and digital against any unauthorized access or destruction. It is a requirement of every business as it ensures that personal data is available to authorized users, and is confidential, secure and untouched. It also helps to in preventing the loss or compromising of crucial information in the event of a cyberattack. A reliable data security program consists of a variety of tools to ensure six essential best practices:
Authentication is an essential part of any data security strategy. Whether your data are in transit or at rest it is important to confirm that only authorized users have access to your data using credentials, such as passwords or encryption keys, or other methods of authentication such as multi-factor identification (MFA) which requires the user has to provide more than one form of proof.
The company should be able to track the data it uses, and understand the moment when sensitive data is in a particular condition, such as “at rest”, “in transit” or “in use”.
As data accumulation increases it becomes difficult for companies to keep the track of all their sensitive information. This is the reason it’s essential to apply the principle of least privilege which stipulates that users should be given only the information they require to perform their job. By limiting permissions to a minimum, you can boost your overall security posture and reduce bandwidth and storage costs. Your data usage policy should also outline the way data is used and the consequences of any violations to the policy.
