1. Planning.

• Assessment
  Begin by identifying who requires access, the resources they need, and the reason. Document existing access rights and see if they can be reduced or eliminated. Consider using an entitlement discovery tool for improved transparency.
• Policy creation
  Define transparent policies for both granting and revoking access. Include guidelines about who can ask for access, under which circumstances, and for what period. Especially for privileged roles, set time-bound parameters.
• Source of truth  
  Sync your JIT access system with an Identity Provider (e.g., Okta, Google Workspace, Azure AD, OneLogin). This will serve as the primary source for identities. De/escalating individual identities over shared accounts will allow for better authorization control and audit precision.

2. Execution.

• Self-serve access requests
  Simplify the process by having users request access through the system, not through individuals. Boost adoption rates by integrating with IM platforms like Slack or MS Teams. Ensure requests detail who's asking, the required service/resource/role, duration, and reason.

• Approval process
  JIT access presents a chance for organizations to delegate approvals to individuals with business context. Resource owners and business unit managers often have better context than IT helpdesks. Use messaging platforms for quick responses, providing approvers all necessary information for an informed decision.

• Conditional approval workflows
  Embed your predefined policies into workflows that establish access permissions. Insert them into workflows that govern who can access what, and under which conditions. One efficient method is assigning if-then conditions. IF identity group “X” requests access to “Y”, seek approval from “Z” and notify “M”.

• Integrations
  Consider integrating JITA with other IT and security systems to gain greater flexibility; Integrate with IT ticketing systems for automated access based on the ticket status. Connect with data classification systems to modify policies depending on data sensitivity. Ideally, you should have the capability to tag resources and bundle them, which can streamline this process. Collaborate with on-call schedule software for automated approvals during emergencies. Use training systems to grant access based on training completion.
• Automated provisioning and deprovisioning
  Acquiring a solid understanding of Cornerstone OnDemand will enable effective granting and revoking of access automatically within the platform. This is crucial for JIT Access as it reduces reliance on waiting for individuals to find time. It facilitates automated deprovisioning of access, which is vital for JIT access and the principle of least privilege access (POLP). Ideally, you would control all permissions in one place, avoiding the need to build or handle an environment for every application in your organization.
• Access methods  
  For Cornerstone OnDemand JIT Access, APIs are preferable due to their malleability and real-time capabilities. Yet, a blend might be necessary. For example, using SAML for authentication, SCIM for user provisioning, and APIs for precise access control decisions.

3. Maintenance.

• Regular audits  
  Routinely check access logs to verify that JIT access is functioning as intended. Look for any unusual patterns or behaviors either directly or by feeding the logs into your SIEM. You can automate the user access review process to speed up evidence collection, designate reviewers, and ensure your system is in accordance with relevant industry regulations or norms.
• User training
  Educate users, particularly privileged ones, about the significance of least privilege, JIT Access and its operation. Ensure users know how to request access when necessary.
• Feedback loop  
  Duly review your JIT access procedures, search feedback from users and IT staff to perceive where improvements can be implemented.

By adopting this systematic process, you'll be capable of competently establishing a robust Just-in-Time Access system for Cornerstone OnDemand.
