This PLC is first to be awarded critical certification
Last August, the ControlEdge programmable logic controller (PLC; photo) received ISASecure Embedded Device Security Assurance (EDSA) Level 2 certification by exida, the ISO 17065 accredited certification body who conducted the assessment. The certification recognizes the integrity of both the PLC and its development lifecycle, and includes rigorous communication robustness testing, as well as functional and software-development security assessments. ControlEdge PLC is said to be the first PLC to be awarded the ISASecure Level 2 certification, which builds on the Level 1 capabilities by providing additional security features, such as the confidentiality and integrity of data at rest and in motion, detection of unauthorized changes and additional protection against Denial of Service attacks. The ISASecure-compliant controller has advanced features, including a secure boot capability to prevent uploading of unauthorized software and a built-in firewall. PLC communication can also be secured using IPSec to prevent man-in-the-middle attacks and unauthorized access. — Honeywell Process Solutions, Houston
