SCADA setpoint files that keep water treatment stable are far more critical than marketing PDFs on the public website. How should protections differ?
Select an answer to reveal the explanation.
Short Explanation
The setpoints that keep drinking water safe are the crown jewels; the ‘Summer Concerts!’ PDF is a flyer. Crank integrity and availability up for the jewels. Matching flyer-level controls to SCADA is backwards.
Full Explanation
Critical and private/operational data warrant elevated integrity and availability controls relative to public marketing content. SCADA setpoints affecting water treatment illustrate critical operational data whose unauthorized change or loss has severe impact. Uniform minimal controls or weaker protection for critical data than for public PDFs misalign risk. Anonymous world-writable operational files are unacceptable.
