Data security is the protection of data both physical and digital against unauthorised access or destruction. It is a requirement for every business, since it ensures that personal information is available to authorized users and is safe, confidential and secure. It also helps in preventing the loss or compromising of important information in the case of an attack from cyberspace. A solid data protection program is a combination of tools to ensure six best practices essential to a successful program:
Authentication is the most important aspect of any data security strategy. Whether your data is at storage or in transit it is essential to ensure that only authorized users have access to access it with credentials (e.g., passwords, encryption keys) or other methods of identification such as multi-factor authentication (MFA) which requires users to submit more than one type of proof.
The business must be able to identify its application data and recognize the moment 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 the track of sensitive information when data collection grows. It’s important to follow the principle of least privilige which states that only the information that users require to perform their duties must be made available. By limiting permissions to a minimum, you can boost your overall security and cut down on storage and bandwidth costs. Lastly, your data usage policy should clearly define the manner in which data is utilized and set the consequences for any violation.
