Miro Hardening Guide
Visual collaboration security for board sharing, app controls, and export restrictions
Overview
Miro is a visual collaboration platform for whiteboards, diagrams, and design sessions. REST API, OAuth integrations, and public board sharing handle sensitive planning documents and architecture diagrams. Compromised access exposes strategic planning, product roadmaps, and internal processes.
Intended Audience
- Security engineers managing collaboration tools
- Miro team administrators
- GRC professionals assessing visual collaboration security
- Third-party risk managers evaluating design tool integrations

1. Authentication & Access Controls
1.1 Enforce SSO with MFA
Profile Level: L1 (Baseline) NIST 800-53: IA-2(1)
ClickOps Implementation
Step 1: Configure SAML SSO (Enterprise)
- Navigate to: Company Settings → Security → SAML SSO
- Configure SAML IdP
- Enable: Enforce SSO
Step 2: Enable 2FA (Non-SSO)
- Navigate to: Company Settings → Security
- Enable: Require 2FA
1.2 Team Access Controls
Profile Level: L1 (Baseline) NIST 800-53: AC-3, AC-6
ClickOps Implementation
Step 1: Define Team Roles
| Role | Permissions |
|---|---|
| Admin | Full team management |
| Member | Create/edit boards |
| Guest | Board-specific access |
Step 2: Configure Team Settings
- Navigate to: Team Settings
- Configure member permissions
- Set guest access policies
2. Board & Content Security
2.1 Configure Sharing Defaults
Profile Level: L1 (Baseline) NIST 800-53: AC-21
Description
Control board sharing to prevent data exposure.
Rationale
Attack Scenario: Public boards containing architecture diagrams indexed by search engines; competitive intelligence exposed.
ClickOps Implementation
Step 1: Disable Public Sharing
- Navigate to: Company Settings → Security → Board sharing
- Disable: Allow public boards
- Review existing public boards
Step 2: Configure Default Permissions
- Set default share settings
- Restrict external access
- Configure domain restrictions
2.2 Board Export Controls
Profile Level: L2 (Hardened) NIST 800-53: AC-21
ClickOps Implementation
Step 1: Restrict Exports
- Navigate to: Company Settings → Security
- Configure: Export restrictions
- Limit high-resolution exports
3. Integration Security
3.1 Manage Apps
Profile Level: L1 (Baseline) NIST 800-53: CM-7
ClickOps Implementation
Step 1: Audit Installed Apps
- Navigate to: Company Settings → Apps
- Review all installed apps
- Remove unused apps
Step 2: Restrict App Installation
- Configure: App installation policy
- Require admin approval
- Audit app permissions
3.2 API Token Security
Profile Level: L1 (Baseline) NIST 800-53: IA-5
Implementation
Step 1: Manage Access Tokens
- Navigate to: Profile → Apps & integrations
- Audit personal access tokens
- Revoke unused tokens
Step 2: OAuth App Security
- Review authorized apps
- Limit OAuth scopes
- Rotate tokens periodically
4. Monitoring & Detection
4.1 Audit Logs (Enterprise)
Profile Level: L1 (Baseline) NIST 800-53: AU-2, AU-3
ClickOps Implementation
Step 1: Access Audit Logs
- Navigate to: Company Settings → Security → Audit logs
- Review activity events
- Configure SIEM integration
Detection Focus
-- Detect board sharing changes
SELECT user_email, board_name, share_type
FROM miro_audit_log
WHERE action = 'board_share_change'
AND share_type = 'public'
AND timestamp > NOW() - INTERVAL '7 days';
-- Detect bulk exports
SELECT user_email, export_count
FROM miro_audit_log
WHERE action = 'board_export'
AND timestamp > NOW() - INTERVAL '24 hours'
GROUP BY user_email
HAVING export_count > 10;
