Data security is the protection of data both physical and digital against unauthorised access or destruction. It is a fundamental necessity for any company as it guarantees the confidentiality, integrity and availability of personal information to authorized users. It can also prevent the loss or compromise of important information in the case of cyber-attacks. A solid data security program is a combination of tools that ensure these six best practices essential to a successful program:
Authentication and authorization are critical to any data security strategy. Whether your data are at rest or in transport you must ensure that only authorized users have access by using credentials, like encryption keys or passwords or other methods of authentication like multi-factor identification (MFA) where the user has to provide more than one type of proof.
The business must be able to inventory its application data and know when sensitive data is in a particular state, such as “at rest”, “in transit” or “in use”.
It can be challenging for companies to keep records 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 data users require to perform their duties should be provided. By limiting permissions to a minimum, you will improve your overall security posture and reduce bandwidth and storage costs. Your data usage policy must also specify how data will be utilized and the consequences for any violations to the policy.
