1. Planning.

Assessment
Start by identifying who needs access, what resources they require, and why. Document current access rights and see if these can be minimized or eliminated. Consider using an entitlement discovery tool for better visibility.

Policy creation
Define clear policies for both granting and revoking access. Establish guidelines about who can ask for access, in which circumstances, and for how long. Especially for privileged roles, set time-limited parameters.

Source of truth
Synchronize your JIT access system with an Identity Provider (e.g., Okta, Google Workspace, Azure AD, OneLogin). This will act as the definitive source for identities. De/escalating individual identities over shared accounts will allow for better authorization control and audit accuracy.

2. Execution.

• Self-serve access requests
  Make the process simple by having users request access through the system, not through people. Increase adoption rates by integrating with IM platforms like Slack or MS Teams. Make sure requests detail who is asking, the necessary service/resource/role, duration, and reason.

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

• Conditional approval workflows
  Implement your predefined policies into workflows that determine access permissions. Insert them into workflows that dictate who can access what, under what conditions. One effective approach is assigning if-then conditions. If identity group "X" requests access to "Y", seek approval from "Z" and notify "M".

• Integrations
  Consider integrating JIT Access with other IT and security systems to gain more flexibility; integrate with IT ticketing systems for automated access based on ticket status. Link with data classification systems to adjust policies depending on data sensitivity. Ideally, the ability to tag resources and bundle them together 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 De-provisioning  
  Get a solid understanding of BrowserStack to effectively grant and revoke fine-grained access automatically within the service. This is essential for JIT Access because it reduces reliance on waiting for people to find time. It allows for automated deprovisioning of access, which is at the core of JIT access and the principle of least privilege access (POLP). Ideally, you should manage all permissions in one place, not having to create or manage an environment for every application in your organization.
• Access methods  
  For BrowserStack JIT Access, APIs are preferable due to their flexibility and real-time capabilities. However, a mixture may be necessary, for instance, using SAML for authentication, SCIM for user provisioning, and APIs for precise access control decisions.

3. Maintenance.

• Regular Audits
  Regularly check access logs to ensure JIT access is operating correctly. Look for any unusual patterns or activities either directly or by inputting the logs into your SIEM. Automate the user access review process to speed up evidence collection, allocate reviewers, and ensure your system complies with relevant industry regulations or standards.
• User Training
  Teach users, especially privileged users, about the importance of least privilege, JIT Access and how it works. Make sure users know how to request access when necessary.
• Feedback Loop
  Consistently review your JIT access procedures. Request feedback from users and IT staff to understand where improvements can be made.

By following this structured approach, you'll be able to efficiently implement a robust Just-in-Time Access system for BrowserStack.
