1. Planning.

• Assessment
  Begin with recognizing the need for access, what resources they require, and why. Jot down current access privileges and figure out if they can be diminished or completely removed. An entitlement exploration tool may deliver better transparency.
• Policy creation
  Develop comprehensive policies for both approving and eliminating access. Incorporate guidelines specifying who can appeal for access, under which scenarios, and for what time span. Especially for privileged roles, decide time-bound parameters.
• Source of truth
  Align your JIT access mechanism with an Identity Provider (e.g., Okta, Google Workspace, Azure AD, OneLogin). Use this as the key source of identities. Ascending and descending individual identities over mutual accounts will result in improved authorization control and audit precision.

2. Execution.

• Self-serve access appeals
  Streamline the process by allowing users to request access through the system instead of the individuals. Enhance adoption rates by integrating with IM platforms like Slack or MS Teams. All requests should detail who's requesting, the required service/resource/role, duration, and reason.

• Approval mechanism
  JIT access presents a chance for institutions to delegate approvals to individuals with business context. Resource owners and business unit managers often possess better context than IT helpdesks. Employ messaging platforms for quick responses, granting approvers all necessary details for a sound decision.

• Conditional approval workflows
  Embed your predefined policies into workflows determining access permissions. Assign them to workflows dictating who can access what, and under which conditions. "If-then" conditions work effectively. IF identity group "X" requests access to "Y", seek approval from "Z" and notify "M".

• Integrations
  Consider integrating JITA with other IT and security mechanisms for added flexibility.
• Automated provisioning and deprovisioning
  Have a thorough understanding of BugSnag to efficaciously grant and revoke access within the service automatically. This is vital for JIT Access as it minimizes the dependency on individuals finding time. It enables automated deprovisioning of access, reinforcing JIT access and the principle of least privilege access ( POLP). You should ideally manage all permissions in a single place, eliminating the need to build or manage a separate environment for each application in your organization.
• Access methods
  For BugSnag JIT Access, APIs are optimal due to their adaptability and real-time capabilities. However, a blend might be necessary. For instance, using SAML for authentication, SCIM for user provisioning, and APIs for precise access control decisions.

3. Maintenance.

• Regular audits
  Carry out periodic checks of access logs to confirm the JIT access is operating as expected. Look out for any peculiar patterns or behaviors either directly or by feeding the logs into your SIEM. Assure your system abides by relevant industry norms or standards through an automated user access review process.
• User training
  Train users, particularly privileged ones, about the importance of least privilege, JIT Access and how it works. It's essential that users know how to request access when required.
• Feedback loop
  Regularly review your JIT access procedures. Look for feedback from users and IT personnel to comprehend where ameliorations can be made.

By adhering to this systematic approach, you'll be capable of effectively implementing a solid Just-in-Time Access system for BugSnag.
