Data security shields physical and digital data from unauthorised access and destruction. It is a vital necessity for any company, as it ensures the security, integrity and confidentiality of personal data to authorized users. It also helps to prevent the loss of crucial information due to a cyberattack or a data breach. A good data security program is a combination of tools that ensure these six fundamental best practices:

Authentication is essential to any strategy to secure data. No matter if your data is storage or in transit it is essential to ensure that only authorized users are able to access it by using credentials (e.g., passwords, encryption keys) or other methods of identification, like multi-factor authentication (MFA) which requires users to submit more than one type of verification.

The business must be able of identifying its application data and be aware of what data is sensitive and in a specific state, such as “at rest”, “in transit” or “in use”.

It can be difficult for organisations to keep track of sensitive information as the amount of data collected increases. It is essential to adhere to the principle of least privilige, which states that only the information that users need for their jobs should be provided. By limiting permissions to the minimum, you can improve your overall security posture and reduce storage and bandwidth costs. Additionally, your data usage policy should specify how data is used and set the consequences for any violation.
