IRS WISP Readiness

IRS WISP Policies, Documents, and Evidence Checklist

Organize IRS WISP policies, documents, and evidence checklist so control statements, operating practice, ownership, and current evidence can be reviewed together without losing context.

CISO-led guidance from Ali Hassani, backed by 25+ years of IT, cybersecurity, compliance, and infrastructure experience.

Evidence should demonstrate that safeguards are designed, implemented, reviewed, and corrected over time.

Build an Evidence Library, Not an Oversized Binder

The governing WISP should remain readable and point to controlled supporting records. Screenshots, inventories, contracts, training records, logs, scan reports, backup results, and incident artifacts should be maintained by their owners with review dates, retention rules, and access restrictions.

The Control-to-Evidence Index

For each control, identify the policy reference, accountable owner, systems in scope, evidence source, collection frequency, storage location, retention period, and last validation date. This index exposes controls that are documented but not operating, or operating without reliable proof.

Governance records
Approved WISP, scope statement, qualified-individual designation, risk acceptance, exception approvals, meeting records, and leadership reports.
Environment records
Data inventory, system inventory, network diagrams, application owners, privileged accounts, integrations, and backup scope.
Technical records
MFA coverage, encryption status, patch compliance, vulnerability remediation, EDR health, logging, alert review, and restore tests.
People and provider records
Training, acknowledgements, access changes, terminations, provider due diligence, contracts, findings, and offboarding.

Evidence Quality Tests

  • Current: the artifact reflects the present environment and relevant review period.
  • Traceable: a reviewer can connect it to a named control, system, population, owner, and date.
  • Complete: it covers the relevant population rather than one convenient example.
  • Protected: access is restricted and sensitive details are minimized.
  • Repeatable: the firm can collect it again without reconstructing the process from memory.

Collect Proof Without Creating Another Data Exposure

Screenshots should show enough context to identify the system, configuration, date, and reviewer. Redact taxpayer information, passwords, recovery codes, secret keys, tokens, and unnecessary personal information. Evidence repositories should have access control, retention, backup, and secure-disposal rules of their own.

A Document Architecture That Can Survive an Audit

Level 1

Governing WISP

Program purpose, scope, authority, Qualified Individual, risk method, safeguard domains, reporting, and maintenance.

Level 2

Policies and standards

Access, acceptable use, encryption, endpoints, remote work, backup, logging, incidents, providers, retention, and disposal.

Level 3

Procedures and runbooks

Onboarding, offboarding, access review, restore testing, alert handling, remediation, escalation, and evidence collection.

Level 4

Operating records

Approvals, reports, tickets, logs, screenshots, training, tests, risk decisions, exceptions, and corrective actions.

This hierarchy keeps policy stable while allowing procedures and evidence to change with technology. Every record should map to a control objective and owner.

Sample Control-to-Evidence Register

Control Population Evidence source Frequency Quality concern
MFA coverage Workforce and privileged cloud accounts Identity-provider registration export Monthly Investigate active exceptions
Access review Tax, payroll, portal, email, and administrator accounts Approved user and role report Quarterly and after staffing change Confirm business need
Backup recovery Systems and data identified as recoverable Restore test with timing and integrity Risk-based A job log is not a restore test
Vulnerability remediation Endpoints, servers, network devices, applications Scan, ticket, exception, and rescan Risk-based cycle Find assets missing from scope
Provider review Critical and privileged providers Due diligence, contract, findings, reassessment Before use and periodically Validate the contracted service
Secure disposal Expired records, devices, media, paper Deletion log, sanitization record, certificate Per schedule Include copies and provider data

Common Evidence Failures and Corrections

  • Screenshot without context: identify system, tenant, date, scope, and reviewer while redacting secrets and taxpayer data.
  • Policy without population: name the users, devices, systems, and locations covered.
  • One successful example: confirm the sample represents the full population and review period.
  • Stale inventory: reconcile identity, device-management, finance, procurement, and provider records.
  • Open finding without ownership: assign risk, owner, target date, interim safeguard, approval, and validation.
  • Evidence stored insecurely: protect the repository with least privilege, MFA, retention, backup, and logging.

IRS Publication 5708 provides a WISP starting point. The evidence architecture should extend it to the firm’s real systems and procedures.

Evidence-focused WISP review

Ali Hassani’s Approach to Documentation and Control Validation

Ali Hassani, CISO, uses more than 25 years of security, compliance, infrastructure, and IT operations experience to evaluate whether documents reflect the real environment. His review can connect policies to user populations, devices, applications, providers, testing records, remediation tickets, and management approvals.

The goal is not to manufacture paperwork. It is to identify missing ownership, incomplete populations, stale evidence, unsupported exceptions, and findings that were marked closed without validation. Ali can coordinate this work with internal teams or an MSP and organize the results into an executive-ready remediation record.
