How to read this audit

This review assesses how the response engages the cited finding or recommendation, not whether the respondent’s factual or legal claims are correct. Implementation descriptions are agency claims or commitments, not independently verified completion. Citations use PDF page numbers, including cover pages. This packet concatenates the original PDFs without changing their pages. cybersecurity-it-response.pdf: packet pages 1–9; cybersecurity-board-response.pdf: packet pages 10–17. Each audit names its respondent and response date. Original-source notes: The final recommendation’s response subheading says R7, but the surrounding R8 text, implementation heading, and quarterly-reporting subject clearly identify R8. The cover letter has a stale 2020–2021 subject line; its body and Attachment A identify the current cybersecurity investigation. The final recommendation’s response subheading says R7, but the surrounding R8 text, implementation heading, and quarterly-reporting subject clearly identify R8.
