FINRA Broker-Dealer Cybersecurity Guidance Expert

Stub-depth expertise for FINRA Cybersecurity Rules (builds on SEC Reg S-P and SEC 17a-4). This plugin is scaffolded from the SCF crosswalk (17 SCF controls map to 39 framework controls) and defers to /grc-engineer:gap-assessment for the actual compliance check.

Framework identity

SCF framework ID: usa-federal-sro-finra
Region: Americas
Country: US
Regulator: FINRA (Financial Industry Regulatory Authority)
Canonical source: FINRA cybersecurity guidance for broker-dealers

Scope and posture (placeholder — fill in when leveling up)

TODO: replace with framework-specific overview. Minimum sections for Reference-depth upgrade:

Territorial scope (who and where the framework applies)
Controlled-entity obligations (controller, processor, covered entity, etc.)
Mandatory timelines (breach notification, assessment cadence)
Regulator and enforcement mechanism
Interaction with other frameworks (adequacy decisions, mutual recognition)

Command routing

All commands in this plugin route through /grc-engineer:gap-assessment with framework ID usa-federal-sro-finra. Reference-depth plugins add:

evidence-checklist — framework-native evidence by control family
scope — applicability determination for the organization

Full-depth plugins add framework-specific workflow commands (examples in sibling plugins like soc2, fedramp-rev5, pci-dss).
