1. Planning.

• Assessment
  Begin by determining the users who need access, the resources they require, and the basis of their need. Document current access rights to see if they can be minimized or eliminated. Use an entitlement discovery tool for increased visibility.
• Policy creation
  Develop clear policies for granting and revoking access. Lay out criteria on who can request access, under what circumstances, and for how long. For privileged roles specifically, establish time-bound parameters.
• Source of truth
  Align your JIT access system with an Identity Provider such as Okta, Google Workspace, Azure AD, OneLogin. Let this act as the ultimate source for identities. Individual identities escalation over shared accounts can lead to improved authorization control and audit accuracy.

2. Execution.

• Self-serve access requests
  Make the procedure easier by allowing users to request access through the system instead of individuals. Improve adoption rates by amalgamating with IM platforms like Slack or MS Teams. Ensure requests include details like who's asking, required service/resource/role, duration, and reason.

• Approval process
  JIT access facilitates businesses to assign approvals to individuals with business context. Resource owners and business unit managers often understand better than IT helpdesks. Incorporate messaging platforms for quick responses, providing approvers all necessary details for an informed decision.

• Conditional approval workflows
  Integrate your predefined policies into workflows that govern access permissions. Include them in approval workflows that state who can access what, and under which conditions. An effective method is to assign if-then conditions.

• Integration
  Consider fusing JIT with other IT and security systems for added flexibility; Combine with IT ticketing systems for automated access based on ticket status. Connect with data classification systems to fine-tune policies depending on data sensitivity. Ideally, you should have the ability to tag resources and package them together. Collaborate with on-call schedule software for automated approvals during emergencies. Use training systems to grant access upon training completion.
• Automated provisioning and depovisioning
  Gain a sound understanding of Cloud Repo to autogrant and revoke access within the service efficiently. This is crucial for JIT Access by cutting down reliance on individual availability. It allows for automated deprovisioning of access, a core concept of JIT access and the least privilege access principle (POLP). The goal should be to manage all permissions in one place without creating or managing an environment for each application in the organization.
• Access methods
  For Cloud Repo JIT Access, APIs are preferred for their versatility and real-time capabilities though blending might be required. For instance, using SAML for authentication, SCIM for user provisioning, and APIs for fine-grained access control decisions.

3. Maintenance.

• Regular audits
  Regularly review access logs to ensure JIT access is performing as expected. Check for any unusual patterns or behaviors either directly or by feeding logs into your SIEM. User access review processes can be automated to quicken evidence collection, delegate reviewers, and ensure system compliance with relevant industry regulations or standards.
• User training
  Train users, particularly privileged users, about the importance of least privilege, JIT Access, and its workings. Ensure users understand how to request access when necessary.
• Feedback loop
  Ensure a consistent review of JIT access procedures. Gather feedback from users and IT staff to recognize areas that can be bettered.

By adhering to this structured method, you'll efficiently establish a robust Just-in-Time Access system for Cloud Repo.
