$140K. When you mess up, the lights go out for real.

Final episode of TechUpdates Special Series. The most consequential security job almost nobody talks about — defending the systems that keep the country running. Power grids. Water utilities. Petrochemical plants. Pipelines.

What you'll hear:

• What OT/ICS defenders actually do — segmentation, SCADA patching, PLC defense, plant-engineer coordination

• Comp reality — why OT pays 40–60% less than cloud security at the same companies, and the "purpose tax"

• The real stakes: Ukraine 2015 grid attack · Triton 2017 (Saudi Arabia) · Oldsmar 2021 · Aliquippa 2023 · Volt Typhoon pre-positioning across U.S. critical infrastructure

• A real day — substations at 6 AM, vendors that still ship Windows 7 SCADA, plant managers explaining why your last predecessor retired in 2015

• The two paths in — plant engineer to security, or IT security to OT — and why CISSP doesn't help but GICSP does

• LinkedIn's "critical infrastructure defender" vs. the actual day (30% travel to plants, 20% talking plant engineers into caring)

When you mess up here, there's a body count. When you do it right, nobody notices the lights stayed on. That's the whole job description. And it matters more every year as adversaries pre-position inside the operational networks of utilities they intend to disrupt on a date of their choosing.

That wraps the Special Series. Pick the role that fits you. The field is wide.
