Data Security Basics

Data security is one of the most crucial aspects of the infrastructure of a business. It protects sensitive data from hackers and ensures only those who are authorized to access it. Data security also helps organizations to adhere to the regulations of their industry, and to maintain employee and customer trust.

The most commonly used security measures for data include the use of encryption, access control and other tools that ensure the integrity, confidentiality, and availability of your company’s data. The encryption process scrambles data so that it is unreadable by anyone who doesn’t have the appropriate key. Access control utilizes roles and policies to limit access to the database or file level using the least privilege principle. Other tools like masking and tokenization replace sensitive data with a less sensitive representation that’s still useful to authorized users, however, hackers aren’t able to exploit.

Backups and other copies are also essential in order to ensure that you can recover in the event that cyber-attacks occur or hardware failures. Regular, full, differential, and incremental backups should be kept in different locations to protect against data loss and unauthorised modifications.

The best data security measures are simple and inexpensive, like needing strong passwords and frequent change of credentials. Employee training can transform employees into human firewalls, enabling them to recognize and resist attacks using social engineering. Other data security basics include multi-factor authentication as well as safeguarding devices and networks against unauthorised access. Also an information privacy policy and clear notices will allow customers to understand the way their personal data is used by your business and also allow them to choose to opt-out of any data collection.
