Data security is one of the most important aspects of the infrastructure of a business. It safeguards sensitive information from hackers and ensures only the appropriate people have access to it. Data security also aids organizations to comply with industry regulations and keep trust between employees and customers.

The most common data security measures involve the use of access control, encryption and other tools to ensure the confidentiality, integrity and accessibility of your organization’s information. Encryption scrambles data to make it inaccessible to anyone who doesn’t have the key to decode it. Access control utilizes rules and roles to restrict database or file level access according to 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 take advantage of.

Backups and other copies are also necessary to ensure you’re able to recover in the event that cyber-attacks occur or hardware failures. To protect your data from loss or unauthorized changes you should make regular, full, differential and incremental backups in a variety of locations.

The best security measures to protect your data are easy and cost-effective. For instance, you can require strong passwords and changing credentials frequently. Training for employees can transform them into human firewalls, helping them recognize and thwart attacks using social engineering. Other essentials for data security include implementing a multi-factor security, and securing devices and networks from unauthorized access. A data privacy policy and clear notices can help your customers to understand the ways in which they are used by your company and provide them with the option to opt out.
