Question

How do you implement data encryption within an industrial network?

Accepted Answer

Data encryption within an industrial network is implemented to protect sensitive data from unauthorized access and tampering. Encryption transforms data into an unreadable format, called ciphertext, using an encryption algorithm and a key. Only authorized users with the correct key can decrypt the data back into its original readable format. Several methods can be used to implement data encryption in an industrial network. One approach is to use VPNs (Virtual Private Networks). A VPN creates a secure, encrypted connection between two points over a public network, such as the internet. This protects data transmitted between the plant network and remote locations, such as a remote monitoring station or a cloud-based data analytics platform. Another approach is to use encryption protocols, such as TLS/SSL (Transport Layer Security/Secure Sockets Layer) or IPSec (Internet Protocol Security), to encrypt data transmitted between devices on the network. TLS/SSL is commonly used to secure web traffic and can also be used to encrypt data transmitted between HMIs and PLCs. IPSec is a more robust encryption protocol that can be used to secure all IP traffic between devices. Encrypting data enhances security.
