Data Security Basics

Data security is one of the most important aspects of a company’s infrastructure. It protects sensitive data from hackers and ensures only the right people can access it. Data security also assists companies to adhere to the regulations of their industry, and to maintain employee and customer trust.

Security measures for data usually consist of comprised of encryption and access control. These tools help protect the integrity, confidentiality and accessibility of data within your organization. Encryption encrypts the data in a way that it cannot be read by anyone who doesn’t have the appropriate key. Access control is based on the concept of least privilege and employs roles and policies to limit access to files or databases. Other tools like masking and tokenization replace sensitive data with an uninvolved representation that’s still useful to authorized users but that hackers can’t exploit.

Finally, backups and other redundant copies of your vital data are essential to ensure you’re able to recover from cyber attacks and hardware failures. To protect against data loss or unauthorised changes it is recommended to keep regular, full, differential and incremental backups in different locations.

Many of the best strategies to protect your data are easy and cost-effective. For instance, requiring strong passwords and changing credentials frequently. Training for employees can transform them into human firewalls, helping them to identify and fight attacks by social engineering. Other security measures for data include multi-factor authentication as well as safeguarding networks and devices from unauthorised access. Additionally an information privacy policy and clear notifications can help customers understand the way their personal data is used by your business and permit them to opt-out of any collection.
