Finance & Accounting: Security & Compliance Brief
Note: This is general information and not legal advice.

Executive Summary
- Account takeover and impersonation (wire-fraud and invoice diversion).
- Client PII and financial records in email, endpoints, and shared drives.
- Due diligence / vendor reviews that require control evidence and documentation.
- Identity: MFA coverage, conditional access, least-privilege admin roles.
- Email + verification workflows: reduce impersonation and confirm payment changes out-of-band.
- Recovery: tested backups and documented restoration procedures.
- Evidence: maintain logs, policies, and screenshots that prove controls are operating.
Common risk scenarios
- Invoice diversion: attackers change payment instructions after compromising email.
- Privilege sprawl: too many admins and shared accounts make accountability impossible.
- Data spill: client files shared broadly, synced to unmanaged devices, or stored in shadow tools.
- Backup surprises: backups exist but haven’t been restore-tested in months.
Controls that help most firms quickly
- MFA + conditional access: see MFA guide and Conditional Access guide.
- Admin and access hygiene: see RBAC guide and onboarding/offboarding.
- Email authentication: see DMARC/DKIM/SPF guide.
- DLP and controlled sharing: see DLP guide.
- Backups you can prove: see backup & DR testing.
Evidence: what “audit-ready” looks like
A lot of compliance pain is preventable if you maintain evidence continuously. Focus on small, repeatable artifacts: access control policy, admin lists, MFA coverage, device coverage, backup test logs, and incident response contacts.
If you regularly face questionnaires, start with vendor security questionnaires and build from there.
AI usage guardrails
AI can be useful in finance workflows, but you need governance: approved tools, data classification, and verification. Use AI governance & data security as a starting point.
Common Questions
Does GLBA apply to us?
It may. GLBA can apply to financial institutions and certain firms that handle consumer financial information. The right approach is to confirm applicability, then implement a defensible safeguards program with evidence.
What do clients and insurers usually expect to see first?
Clear MFA coverage, controlled admin access, device management, tested backups, and documented response procedures. Many reviews come down to “can you prove this is actually in place?”
What reduces wire-fraud risk the most?
Strong identity and email controls plus process: MFA, conditional access, email authentication, and out-of-band verification workflows for payment instruction changes.
Do we need a SIEM?
Not always on day one. What you do need is reliable logging for critical systems and a clear escalation process. A SIEM becomes valuable once you have enough signals and someone accountable to act on them.
What about AI tools used for bookkeeping, analysis, or client work?
Treat AI as a data-processing vendor. Define which tools are approved, what data is allowed, and how outputs are verified. In regulated contexts, document decisions and maintain auditability.
Can you co-manage with internal IT?
Yes. We can help set the baseline, implement controls, and maintain evidence while your team retains day-to-day ownership.
