As a vital component of your cybersecurity strategy data encryption helps protect sensitive data that is stored in your company’s computer systems or transmitted across public networks. Data encryption methods will have to evolve as cyberattacks become increasingly sophisticated and computing systems get better. Understanding when and how to utilize this security method is crucial to ensure that your data is safe.
Encryption refers to the process of coding data in a way that it becomes scrambled or inaccessible to anyone else without the encryption key. The encrypted text can then be stored or transmitted in order to prevent any unauthorized access.
When properly implemented, data encryption ensures that hackers are unable to gain access to the data even if they steal it digitally or physically. it. It’s often the foundation of a solid security framework and is often required by compliance standards to safeguard certain kinds of data, such as healthcare data with HIPAA regulations and payment card data governed by PCI DSS regulations and personal data for GDPR compliance.
To safeguard sensitive information, companies must implement strong security measures for data encryption. This includes encryption at rest, which helps protect the data stored on hard drives cloud storage, USB devices and smartphones from physical theft or malicious attacks which can occur when a device is connected into a network that is accessible to the public. Data encryption in transit can also be used to safeguard information that is actively transferred from one device or system to another. This includes instant messaging, email and web traffic. This protects against malicious activities like man-in the-middle attacks.
