As a key element of your cybersecurity strategy Data encryption protects the sensitive information stored in your company’s computer systems or transferred across public networks. Data encryption techniques will need to change as cyberattacks become more sophisticated and computing systems get better. To help ensure that your data is secure, it’s important to understand how this security method works and when it’s appropriate.
The process of encryption involves coding data in such a way that it is unreadable or deciphered by anyone who doesn’t possess the encryption key. This ciphertext can then be stored or transmitted to stop the unauthorized access.
When used correctly If used properly, encryption of data makes it impossible for hackers gain access to the information, regardless of whether the information is stolen physically or digitally. It’s often the foundation of a robust cybersecurity framework and is frequently required by compliance standards to protect specific types of data like healthcare data that is subject to HIPAA regulations and payment card data governed by PCI DSS regulations and personal data required for GDPR compliance.
With mobile devices and remote work becoming more prevalent it’s vital for companies to implement strong encryption strategies for data to keep their sensitive information safe. This includes encryption at the rest, which protects data stored on hard drives, cloud storage, USB devices, and smartphones against physical theft or malicious attack that can occur when a device is connected to a network that is open to public access. Data encryption during transit is also utilized to safeguard data that is continuously transmitted from one system or device to another. This includes instant messaging, email, and website traffic. This protects against adversity like man-inthe-middle attacks.
