ot availability

The tag 'ot availability' covers discussions about the reliability and uptime of operational technology (OT) systems, particularly in industrial environments. Content under this tag focuses on vulnerabilities and threats that can cause downtime, such as the Siemens CVE-2025-40833 denial-of-service flaw, which affects industrial networking, controller, drive, power, and automation devices. The tag emphasizes that OT availability failures often stem from mundane issues like unpatched firmware, exposed network access, and poor patch sequencing, rather than sophisticated attacks. Topics include patch management, mitigation strategies, and the real-world costs of OT outages, highlighting the importance of maintaining operational continuity in critical infrastructure.
