1. Planning.

• Assessment
  Start by identifying which team members require access, which resources they need access to, and why. Document existing access privileges and see if they can be reduced or possibly eliminated. Consider using a permission discovery tool for enhanced visibility.
• Policy creation
  Develop distinct policies for granting and revoking access. Define guidelines on who can request access, under what situations, and for what duration. Especially for roles with elevated privileges, establish time-constrained limitations.
• Source of truth
  Sync your JIT access procedures with an Identity Provider such as Okta, Google Workspace, Azure AD, OneLogin. This will help in maintaining a reliable source for identity validation. Reducing the dependency on shared accounts and focusing on individual identities promotes better control over authorization and improves audit accuracy.

2. Execution.

• Self-serve access requests
  Streamline the process by allowing users to request access directly through the system, bypassing human intervention. Improve user adoption rates by integrating with IM platforms like Slack or MS Teams. Ensure requests contain necessary details such as the requester's details, required service/resource/role, duration, and reason.

• Approval process
  JIT access provides organizations the flexibility to delegate approvals to personnel who have a deeper understanding of the business context, such as resource owners or business unit managers, compared to the IT helpdesk. Utilize messaging platforms for fast responses, providing decision-makers with all the necessary information.

• Conditional approval workflows
  Incorporate your pre-established policies into workflows that dictate access rights. Embed them into processes that determine who can access what and under what conditions. This can be optimized by implementing if-then conditions. IF identity group “X” requests access to “Y”, approval from “Z” is required and notification to “M” is sent.

• Integrations
  Consider integrating JIT access with other IT and security systems for improved flexibility. Link with IT ticketing systems for automated access based on ticket status. Connect with data classification systems for adaptive policies depending on data sensitivity. The ability to tag and group resources can significantly streamline this process.
• Automated provisioning and deprovisioning
  Understanding Azure DevOps effectively will allow for the fine-tuning of access rights within the system. This is crucial for JIT access as it reduces the need to rely on human availability to grant access. This also allows for an automated way of revoking access which is fundamental for JIT access and the principle of least access privilege (POLP). Ideally, managing all permissions in one place would save you from having to construct or maintain a separate environment for every application in your organization.
• Access methods
  For Azure DevOps JIT Access, APIs are ideal owing to their flexibility and real-time capabilities. However, a mixture of methods might be necessary. For example, utilizing SAML for authentication, SCIM for user provisioning, and APIs for precise access control decisions.

3. Maintenance.

• Regular audits
  Routinely examine access logs to ensure JIT access is functioning as intended. Watch out for any unusual patterns or activities, either directly or by incorporating the logs into your SIEM. You can automate the user access review process to expedite evidence gathering, delegate reviewers, and ensure system compliance with relevant industry regulations or standards.
• User training
  Train your users, particularly those with elevated privileges, about the significance of least privilege, JIT Access, and its procedures. Make sure users are familiar with the process of requesting access when needed.
• Feedback loop
  Consistently evaluate and refine your JIT access protocols. Gather feedback from users and IT staff to identify areas for improvement.

By adopting this methodical approach, you'll be able to efficiently implement a robust Just-in-Time Access procedure for Azure DevOps.
