Data Security Basics

Data security is a critical aspect of any organization's infrastructure. It shields sensitive data from hackers and ensures only the appropriate people have access to it. In addition data security allows organizations to adhere to industry standards and maintain employee and customer confidence.

Data security measures are usually combined with encryption and access control. These tools protect confidentiality, integrity and availability of data within your business. The encryption process scrambles data so that it can't be read by anyone who does not possess the key. Access control employs policies and roles to limit access to databases or files using the least privilege principle. Other tools, such as tokenization and masking, substitute sensitive information with less sensitive representations that are still useful for authorized users but that hackers cannot exploit.

Backups and other copies are also required to ensure you can recover in the event of cyber-attacks or hardware failures. To protect your data from loss or unauthorised changes it is recommended to keep regular, complete, differential and incremental backups at different locations.

A lot of the best measures for protecting your data are simple and affordable. For instance, requiring strong passwords or changing your credentials frequently. Employee training can also transform employees into a human firewall, helping to identify and fight social engineering attacks. Other security measures for data include the implementation of a multi-factor authentication as well as securing devices and networks from any unauthorized access. A privacy and data security policy, along with clear notifications can help your customers be aware of the methods employed by your organization and give them the choice to opt-out.
