Regulatory Compliance

A practitioner's framework for achieving and maintaining regulatory compliance. This skill covers SOC 2, HIPAA, and PCI-DSS - the three frameworks most commonly demanded by enterprise customers - with an emphasis on how to build a sustainable compliance program, not just pass a one-time audit.

When to use this skill

Trigger this skill when the user:

• Prepares for a SOC 2 Type I or Type II audit
• Implements HIPAA technical, administrative, or physical safeguards
• Works toward PCI-DSS compliance for payment card environments
• Conducts a risk assessment or gap analysis
• Builds or updates a controls matrix
• Automates evidence collection for ongoing compliance
• Manages an active audit with an external auditor
• Defines policies for data handling, access control, or incident response

Do NOT trigger this skill for:

• General security hardening not tied to a specific framework (use backend-engineering security references instead)
• Legal or attorney-client questions - always refer to qualified legal counsel for jurisdiction-specific obligations

Key principles

1. Compliance is continuous, not a project - Passing an audit is a snapshot in time. The goal is a living program with controls that operate daily. Scrambling for evidence two weeks before an audit means your controls are theater, not real.

2. Automate evidence collection - Manual evidence collection does not scale and creates audit fatigue. Instrument your systems to produce compliance artifacts automatically: access logs, change records, configuration exports, and training completions should all be captured without human intervention.

3. Controls should serve the business - A control that creates so much friction that engineers route around it is worse than no control. Design controls that are least-privilege without being obstructive. If teams hate a control, find a more elegant implementation, not an exception.

4. Start with the framework that customers demand - Do not attempt all three frameworks simultaneously. Survey your enterprise customers and prospects. SOC 2 unblocks most B2B SaaS deals. HIPAA is required the moment you touch protected health information. PCI-DSS is mandatory if you store, process, or transmit cardholder data. Pick one, reach Type II, then expand.

5. Gap analysis before implementation - Never start writing policies or deploying tools without first mapping your current state to the required controls. A gap analysis reveals which controls are already satisfied (often 30-40%), which need tooling, and which need process changes. Skipping it wastes months building things you already have.

Core concepts

Control frameworks

A control framework is a structured set of requirements that an organization must satisfy to meet a compliance standard. The three major frameworks covered here:

Framework	Owner	Core focus	Audit type	Who needs it
SOC 2	AICPA	Trust Services Criteria (security, availability, confidentiality, privacy, processing integrity)	Third-party CPA audit	B2B SaaS, cloud services
HIPAA	U.S. HHS	Protected health information (PHI) privacy and security	Self-attestation + OCR enforcement	Healthcare, covered entities, business associates
PCI-DSS	PCI Security Standards Council	Cardholder data environment (CDE) protection	QSA audit (Level 1) or SAQ (Level 2-4)	Any entity storing/processing/transmitting card data

Evidence types

Auditors require evidence that controls are designed correctly (Type I) and operating effectively over time (Type II). Evidence categories:

• Configuration exports - Screenshots or exports showing system settings (MFA enabled, encryption at rest, logging enabled)
• Access reviews - Periodic exports showing who has access to what, reviewed and signed off by a manager
• Policy documents - Written policies with version history and employee acknowledgment records
• Training records - Completion logs for security awareness and role-specific training
• Incident records - Log of security incidents with detection, response, and closure
• Vendor reviews - SOC 2 reports or security questionnaires for third-party vendors
• Change management records - Git history, PR approvals, deploy logs showing change control processes

Audit process

Gap Analysis -> Remediation -> Readiness Review -> Audit -> Report
     |               |               |                |         |
  4-8 weeks      3-12 months     4-6 weeks        4-8 weeks  2-4 weeks
  Map controls   Build controls  Mock audit       Evidence   Final report
  to current     that are        with auditor     collection issued
  state          missing         (optional)

Type I audit: point-in-time snapshot that controls are designed appropriately. Type II audit: 6-12 month observation period proving controls operate continuously. Always target Type II - enterprise procurement teams reject Type I as insufficient.

Risk assessment

Risk assessment is the foundation of every compliance framework. It identifies threats to your systems and data, evaluates their likelihood and impact, and drives the prioritization of controls.

Risk score formula: Risk = Likelihood (1-5) x Impact (1-5)

Score	Action
20-25	Critical - immediate remediation required
12-19	High - remediate within 30 days
6-11	Medium - remediate within 90 days
1-5	Low - accept with documented rationale or remediate in backlog

Common tasks

Prepare for SOC 2 Type II

A realistic 12-18 month roadmap for a startup with no prior compliance program:

Months 1-2: Gap analysis and scoping

• Define the system boundary (what systems are in scope)
• Map all Trust Services Criteria to existing controls
• Identify gaps and assign remediation owners
• Select a compliance platform (Vanta, Drata, Secureframe, or manual)

Months 3-8: Remediation

• Implement missing technical controls (MFA everywhere, encryption at rest and in transit, logging and monitoring, vulnerability scanning, access reviews)
• Write required policies (security, access control, incident response, business continuity, vendor management, change management)
• Run employee security awareness training and document completion
• Conduct vendor reviews for all subprocessors handling customer data

Months 9-10: Observation period start

• All controls must be operating; the clock starts for the Type II period
• Automate evidence collection for operating controls
• Schedule quarterly access reviews and vulnerability scans

Months 11-12: Readiness and audit

• Conduct internal readiness review; fix any findings
• Engage auditor for fieldwork
• Respond to auditor requests within agreed SLAs
• Receive SOC 2 Type II report (6-month or 12-month observation period)

Choose the 6-month observation period for your first report. You can expand to 12-month on renewal. A 6-month report unblocks deals faster.

Implement HIPAA safeguards

HIPAA requires three categories of safeguards for covered entities and business associates handling PHI:

Administrative safeguards (45 CFR 164.308)

• Conduct and document a security risk analysis annually
• Designate a Security Officer responsible for HIPAA compliance
• Implement workforce training with documented completion records
• Establish sanction policies for employees who violate HIPAA
• Define access authorization and management procedures

Physical safeguards (45 CFR 164.310)

• Control physical access to systems that contain PHI
• Implement workstation use and security policies
• Establish device and media controls (encryption, disposal procedures)

Technical safeguards (45 CFR 164.312)

• Unique user identification for all PHI access (no shared accounts)
• Automatic logoff after period of inactivity
• Encryption and decryption of PHI at rest and in transit
• Audit controls: hardware, software, and procedural mechanisms to log access to PHI
• Integrity controls: detect unauthorized PHI alteration or destruction
• Transmission security: TLS 1.2+ for all PHI in transit

Minimum Necessary standard - Access to PHI must be limited to the minimum necessary to perform a job function. Implement RBAC and log all PHI access.

Achieve PCI-DSS compliance

PCI-DSS v4.0 has 12 requirements organized around the cardholder data environment:

Requirement	Focus	Key controls
1-2	Network security	Segmented CDE network, firewall rules, no defaults
3-4	Data protection	Do not store SAD; encrypt PAN at rest and in transit
5-6	Vulnerability management	Anti-malware, secure development, patching SLA
7-8	Access control	Need-to-know access, MFA for CDE access, unique IDs
9	Physical security	Physical access controls for CDE hardware
10-11	Monitoring and testing	Log all CDE access, quarterly scans, annual pen test
12	Policy	Security policy, incident response plan, vendor management

The best PCI-DSS strategy is reducing scope. Use a PCI-compliant payment processor (Stripe, Braintree) with iframe/redirect tokenization. If cardholder data never touches your servers, you qualify for SAQ A (the simplest self-assessment questionnaire) rather than a full QSA audit.

Conduct a risk assessment

Follow NIST SP 800-30 or ISO 27005 for a defensible methodology:

1. Identify assets - List all systems, data stores, and third-party services that store or process regulated data
2. Identify threats - For each asset, enumerate threat actors (external attacker, malicious insider, accidental disclosure) and threat events (data breach, ransomware, misconfiguration)
3. Identify vulnerabilities - What weaknesses could a threat exploit? (Unpatched software, weak passwords, no MFA, overly broad access)
4. Calculate risk - Likelihood x Impact for each threat/vulnerability pair
5. Identify controls - Existing controls that reduce likelihood or impact; proposed controls for unacceptable residual risk
6. Document and accept - Risk owner signs off on residual risk. Risk register is reviewed annually and after significant changes

Build a controls matrix

A controls matrix maps each framework requirement to:

• The control (what you do)
• The control owner (who is responsible)
• The evidence type (what proves it)
• The evidence location (where to find it)
• The review frequency (how often it is checked)

See references/controls-matrix.md for a complete SOC 2 Trust Services Criteria controls matrix you can adapt.

Automate compliance monitoring

Manual compliance creates point-in-time snapshots that drift. Automate:

Evidence type	Automation approach
MFA enrollment	Query IdP API (Okta, Google Workspace) on schedule; alert on non-enrolled users
Access reviews	Export IAM group memberships quarterly; route to manager for sign-off via workflow
Vulnerability scans	Run Trivy or Snyk in CI; export results to compliance platform
Patch status	Query endpoint management API (Jamf, Intune); flag overdue patches
Security training	Pull completion data from training platform API
Change management	Git PR merge log automatically satisfies change control evidence
Logging enabled	IaC enforces CloudTrail/audit logging; drift detected by policy-as-code

Compliance platforms like Vanta, Drata, and Secureframe automate most of this via integrations. Evaluate whether the platform cost (typically $15k-$40k/year) is justified by the hours saved vs. manual evidence collection.

Manage the audit process

A well-run audit avoids surprises. Follow this timeline:

T-8 weeks: Auditor kickoff

• Agree on scope, observation period dates, and fieldwork schedule
• Share the controls matrix and request the evidence request list (PBC list)
• Assign an internal point of contact for auditor questions

T-4 weeks: Evidence preparation

• Collect all requested evidence; organize by control number
• Review for gaps or anomalies before submission
• Do not submit evidence you have not reviewed

T-2 weeks: Fieldwork

• Respond to auditor questions within 24-48 hours
• Track open items in a shared log
• Escalate blockers immediately - do not let items age

T-0: Report delivery

• Review draft report carefully for factual errors before it is finalized
• Exceptions (qualified opinions) are negotiable if the evidence was misunderstood
• Attach a management response to any exceptions explaining remediation plans

An exception in a SOC 2 report is not automatically a deal-breaker. Customers read the management response. A clear remediation timeline with evidence of progress is often acceptable.

Anti-patterns

Anti-pattern	Why it fails	What to do instead
Treating compliance as a one-time project	Controls decay, evidence gaps appear, audit fails or findings increase year-over-year	Build a continuous program with automated evidence and quarterly reviews
Scope creep - putting everything in scope	Larger scope = more controls = more cost and audit time	Define the tightest defensible scope; use network segmentation to exclude non-regulated systems
Writing policies nobody reads or follows	Policies without enforcement are paper compliance that auditors see through	Tie every policy to a technical control or an automated check; require annual acknowledgment
Buying a compliance platform before a gap analysis	Platform integrations cover generic controls; custom controls still need manual work	Complete the gap analysis first; then evaluate platforms against your specific control gaps
Using shared accounts to access regulated systems	Violates individual accountability requirements in every major framework	Enforce unique user IDs at the IdP level; fail pipelines that use shared credentials
Deferring the risk assessment until the last month	Risk assessment drives control selection; doing it late means controls may not address real risks	Complete risk assessment in the first gap analysis phase; repeat annually
