The Importance of Data Encryption

Data encryption is an essential component of your cybersecurity plan. It protects sensitive information that’s kept on your company’s computers or transmitted through public networks. Data encryption techniques will need to evolve as cyberattacks become increasingly sophisticated and computing systems improve. To ensure that your information is secure, it’s important to understand how this security method is used and when it’s appropriate.

Encryption involves coding data so that it is unreadable or mangled by anyone who doesn’t possess the encryption key. The encrypted ciphertext is then sent or stored to block unauthorized access to the original information.

When properly used, encryption of data makes it impossible for hackers to gain access to the information, regardless of whether the information is stolen physically or digitally. It is often the basis for a robust cybersecurity system and is often required by compliance standards to safeguard specific types of information like healthcare information that is subject to HIPAA regulations or data from payment cards that are covered by PCI DSS Regulations.

With mobile devices and remote work increasing in popularity it’s crucial for companies to implement effective security strategies for data encryption to ensure that their sensitive data is secure. This includes encryption at rest, which helps protect the data on hard drives cloud storage, USB devices and smartphones from physical loss or malicious attacks which can occur when a device is plugged into a public network. Additionally, data encryption in transit protects information that is actively traveling from one system to another like instant messages, email and website browser traffic. This helps protect against malicious activities such as man-in-the-middle attacks.
