Data encryption is a vital component of your cybersecurity plan. It protects sensitive information that’s kept on your company’s computers or transmitted over public networks. Data encryption methods will have to change as cyberattacks become more sophisticated and computing systems improve. Understanding how and when to apply this security technique is important for ensuring that your data remains protected.

The process of encryption involves coding data in such a way that it is unreadable or unreadable by anyone who does not possess the encryption key. The encrypted ciphertext is then sent or stored to prevent unauthorized access to the original data.

If properly used when used properly, data encryption makes it impossible for hackers to gain access to information, even if they steal it digitally or physically. it. It’s often the foundation of a robust cybersecurity framework and is typically required by compliance standards to safeguard specific types of data like healthcare data that is subject to HIPAA regulations as well as payment card information that meets PCI DSS regulations and personal information to ensure GDPR compliance.

With remote work and mobile devices becoming more commonplace and widespread, it is essential for businesses to implement solid methods of data encryption to ensure their sensitive data remains secure. This includes encryption at rest, which safeguards the data on hard drives, cloud storage, USB devices and smartphones from physical attack or theft which can occur when a device is connected into a network that is accessible to the public. Data encryption in transit is also used to safeguard information that is continuously transmitted from one system or device to another. This includes instant messaging, email and web traffic. This protects against a variety of malicious activities such as man-inthe-middle attacks.
