Policy

Documents with dates. Guidance with sources.

Original publications and current practical guidance have distinct roles. Dates, sources and limitations help you decide how to use each.

Updated · 2026-11-08

Original publications

Original PDFs retain their content, credits, copyright notices and disclaimers. Their historical publication dates are not replaced with the date the website changed. Earlier research figures, product names and role taxonomies are not automatically current.

Current guidance

Practical guides cite primary technical publications. Recommendations need to be assessed against the particular process, architecture, legal duties and safety requirements. A public checklist cannot certify a system or authorise work on it.

Corrections

Send the page, the disputed point and supporting evidence to OTCSA. Source conflicts and gaps are stated rather than filled with invented details. Incomplete document recovery is identified on the relevant page.

Responsible use

The tools run in your browser and help organise a review. They do not connect to, scan or control industrial devices. Their completion count is a record of answers, not a security rating.

People and publications

Meet the publication contributors and webinar participants. Each entry links to the document or event that records their contribution.
