Data Security Basics

Security of data is a vital element of any company’s infrastructure. It shields sensitive data from hackers and ensures only the right people have access to it. Additionally, data security helps organizations adhere to industry standards and maintain customer and employee confidence.

The most commonly used security measures for data protection involve the use of encryption, access control, and other tools that can help safeguard the confidentiality, integrity and accessibility of your organization’s data. Encryption smears data and makes it unreadable to anyone who does not have the key to decode it. Access control uses roles and policies to limit database or file level access, based on the least privilege principle. Other tools, such as masking or tokenization replace sensitive data with an uninvolved representation that’s still beneficial to authorized users, but that hackers can’t exploit.

In the end, backups and other redundant copies of your critical data are necessary to ensure you’re able to recover from cyber attacks and hardware failures. To protect your data from loss or unauthorised modifications, you should store regular, complete, differential and incremental backups in different locations.

A lot of the best methods to secure your data are simple and inexpensive, like having strong passwords, and a regular change of credentials. Training for employees can transform them into human firewalls, enabling them to identify and fight attacks using social engineering. Other essentials for data security include multi-factor authentication as well as safeguarding devices and networks against unauthorised access. A privacy and data security policy, along with clear notifications will help your customers to understand the ways in which they are utilized by your business and give them the choice to opt out.
