The Importance of Data Encryption

As a key element of your cybersecurity strategy data encryption helps protect sensitive data that is stored in your company’s computer systems or transferred across public networks. Data encryption methods will need to evolve as cyberattacks become more sophisticated and computing systems get better. Knowing when and how to employ this method of security is essential to ensure that your data is secure.

The process of encryption involves coding data in a way that it is cryptically encoded or inaccessible to anyone who does not have the encryption key. This ciphertext is then transmitted or stored to prevent unauthorized access to the original data.

If properly used If used properly, encryption of data can make it impossible for hackers to gain access to information even if they digitally or physically steal it. It’s often the core of a solid cybersecurity framework and is frequently required click reference by compliance standards to protect specific types of data like healthcare data that is subject to HIPAA regulations and payment card data that is subject to PCI DSS regulations and personal data required for GDPR compliance.

To safeguard sensitive data companies should implement strong security measures for data encryption. This includes encryption at rest of the data, which guards it stored on hard drives, cloud storage, USB devices, and smartphones against physical theft or attack that could occur when a device is connected to a network that is open to public access. Data encryption in transit can also be used to protect information that is continuously transmitted from one system or device to another. This includes instant messaging, email, and website traffic. This helps to safeguard against malicious activities such as man-in-the-middle attacks.
