1. Planning.

• Assessment
  Begin with identifying who in your organization needs access, which Duo resources they need, and why. Document their current access rights to see if they can be reduced or removed entirely. Using an entitlement discovery tool can provide better visibility into existing access rights.
• Policy creation
  Develop clear policies for granting and withdrawing access. Include guidelines specifying who can request access, under what conditions they can do so, and for how long. Time-bound parameters should particularly be set for privileged roles.
• Source of truth
  Ensure that your JIT access system is synced with an Identity Provider (such as Okta, Google Workspace, Azure AD, OneLogin). This will provide a definitive source for identity reference. Using individual identities rather than shared accounts will allow for better control over authorization and improved accuracy of audits.

2. Execution.

• Self-serve access requests
  Make the process simpler by enabling users to request access through the system, not through individual people. Encourage adoption by integrating it with IM platforms such as Slack or MS Teams. Requests should detail who is asking for access, what service/resource/role they need, how long they need it for, and why.

• Approval process
  JIT access allows organizations to delegate approval authority to individuals with a better understanding of business context. Resource owners and business unit managers often have a better grasp of these matters than IT Helpdesk personnel. Use messaging platforms to expedite responses, ensuring approvers have all required information for making informed decisions.

• Conditional approval workflows
  Incorporate predefined policies to determine access permissions. Implement them in workflows dictating who can access what, under what conditions. An effective method involves assigning if-then conditions.

• Integrations
  Consider integrating your JIT access system with other IT and security systems to enhance flexibility, including IT ticketing systems and data classification systems. Using tag resources can streamline proceedings. Collaborate with on-call schedule software for crisis response. Use training systems for granting access based on completion of relevant training.
• Automated provisioning and deprovisioning
  Gain a solid understanding of Duo's capabilities to grant and revoke access effectively and on a fine-grained basis within the service. This plays a critical role in JIT access as it reduces waiting time for individuals.
• Methods of access
  For Duo JIT Access, the flexibility and real-time capabilities of APIs makes them the ideal method of choice. However, combining different methods may be necessary, such as using SAML for authentication, SCIM for user provisioning, and APIs for precise control over access decisions.

3. Maintenance.

• Regular audits
  Monitor access logs to ensure the JIT access system is functioning as intended. Checks for unusual activity or behaviors can be helped by using your SIEM system. Use automated user access review processes to ensure compliance with industry regulations or standards.
• User training
  Ensure users, especially those with privileged access, understand the JIT Access concept and its importance. Make sure they know how to request access when needed.
• Feedback loop
  Constantly review your JIT access procedures. Encourage feedback from users and IT staff to identify potential improvements.

By adopting this systematic approach, you'll be capable of efficiently implementing a secure Just-in-Time Access system for Duo.
