ot log hygiene

The tag 'ot log hygiene' covers discussions about the security implications of logging in operational technology (OT) environments, particularly in industrial control systems. A key example is CVE-2026-0936, a medium-severity vulnerability in ABB B&R PVI client software where enabled client-side logging can expose credentials. This highlights that logs in OT settings are not harmless and require careful management to prevent information disclosure. The tag emphasizes the need for proper log hygiene to balance engineering convenience with operational security, especially as industrial systems increasingly face cyber threats.
