Data encryption is a crucial part of your cybersecurity strategy. It protects sensitive data that’s kept on your company’s computers or transmitted via public networks. As cyberattacks become more sophisticated and computing systems advance techniques for encryption of data must also change. Knowing when and how to utilize this security method is important for ensuring that your data is protected.

Encryption is the act of making data encoded in a way that it is encrypted or inaccessible to anyone else without the encryption key. The encrypted text can then be stored or transmitted to protect against the unauthorized access.

When used correctly If used properly, encryption of data makes it impossible for hackers to gain access to the information, regardless of whether the data is physically or digitally stolen. It’s often the core of a solid cybersecurity framework and is frequently required by compliance standards to protect specific types of data such as healthcare data with HIPAA regulations, payment card data with PCI DSS regulations and personal information to ensure GDPR compliance.

To safeguard sensitive information businesses must implement robust methods of data encryption. This includes encryption at the rest, which protects data that is stored on hard drives cloud storage, USB devices, and smartphones against physical theft or attack that can occur when a device is plugged in to a public network. Additionally, data encryption in transit safeguards data that is constantly moving from one system to another, such as email, instant messages and browser traffic on websites. This protects against malicious activities such as man-in-the-middle attacks.
