Plan of Action and Milestones (POA&M)

Youth Program Management System (YPMS)

Document Version: 0.1 (initial seed) Date: 2026-09-30 NIST Reference: SP 800-53 Rev. 5 control CA-5 Status: Pre-Development / Pre-Authorization Companion docs: SYSTEM_SECURITY_PLAN.md, NIST_800_53_CONTROL_MAPPING.md

Drafting note. This POA&M is seeded from three sources: (1) the four SSP tailorings above the RFP-derived requirement floor, (2) the six open policy decisions awaiting AO / OYP / Privacy Officer disposition, and (3) the standard pre-ATO deliverables not yet authored or executed (companion docs, data-sharing agreements, foundational build activities, independent assessments). Because YPMS is pre-development — this is an in-house build following the DCYWP / OWC / Employer 360 pattern, and no code exists yet — there are no vulnerability findings to import. Once initial code lands, findings from SAST/DAST/pentest will be added by ID. Items marked [TBD] for owner or target date are pending assignment by DOES leadership.

1. Status Legend

Symbol	Meaning
🔴	Open — work not yet started
🟡	In progress — work underway
🟢	Closed — completed and verified
🔵	Risk accepted — formally accepted by AO with documented rationale
⚪	Deferred — known and tracked, scheduled for a later cycle
❓	Awaiting decision — blocked on AO / OYP / Privacy Officer determination

2. Severity Definitions

Severity ratings align with FedRAMP Continuous Monitoring guidance and the DCYWP POA&M scale for consistency across DOES ATO packages.

Severity	Definition	Default Remediation Window
Critical	Vulnerability allows direct unauthorized access to PII or system control, or blocks ATO decision entirely	30 days
High	Significant risk to confidentiality, integrity, or availability with credible exploit path; or an ATO artifact that must exist before AO can sign	90 days
Moderate	Material weakness without immediate exploit; defense-in-depth gap; or a companion doc/process needed for continuous monitoring	180 days
Low	Hygiene; best practice; no immediate exploit	365 days or next major release
