Miro Hardening Guide

Collaboration Last updated: 2025-12-14

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

Role Permissions
Admin Full team management
Member Create/edit boards
Guest Board-specific access

Step 2: Configure Team Settings

  1. Navigate to: Team Settings
  2. Configure member permissions
  3. 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

  1. Navigate to: Company Settings → Security → Board sharing
  2. Disable: Allow public boards
  3. Review existing public boards

Step 2: Configure Default Permissions

  1. Set default share settings
  2. Restrict external access
  3. Configure domain restrictions

2.2 Board Export Controls

Profile Level: L2 (Hardened) NIST 800-53: AC-21

ClickOps Implementation

Step 1: Restrict Exports

  1. Navigate to: Company Settings → Security
  2. Configure: Export restrictions
  3. 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

  1. Navigate to: Company Settings → Apps
  2. Review all installed apps
  3. Remove unused apps

Step 2: Restrict App Installation

  1. Configure: App installation policy
  2. Require admin approval
  3. Audit app permissions

3.2 API Token Security

Profile Level: L1 (Baseline) NIST 800-53: IA-5

Implementation

Step 1: Manage Access Tokens

  1. Navigate to: Profile → Apps & integrations
  2. Audit personal access tokens
  3. Revoke unused tokens

Step 2: OAuth App Security

  1. Review authorized apps
  2. Limit OAuth scopes
  3. 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

  1. Navigate to: Company Settings → Security → Audit logs
  2. Review activity events
  3. 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;
