The CISA Alert: Security Beyond Solitary Confinement

CISA’s warning underscores a growing business risk: Internet-exposed OT can be disrupted not only by sophisticated attackers, but by the constant background noise of automated scanning and login attempts that can degrade controller performance and threaten uptime. For CIOs and technology leaders, the strategic takeaway is that OT security must balance access with deterministic reliability—favoring network isolation, restricted remote access, and lightweight controls that reduce attacker opportunity without burdening critical systems with unnecessary processing overhead.
