1. Planning.

• Assessment
  Identify the individuals who necessitate access, decide on the resources they demand, and find reasons for the same. Review current access privileges and analyze whether they can be lessened or eradicated. Consider employing an entitlement tracking tool for superior transparency.
• Policy structure
  Establish crystal clear policies for both bestowing and revoking access. Wrap in rules about the particular people who may request access, under what conditions, and for how long. Set out time-bound parameters especially for individuals with privileged roles.
• Absolute source
  Connect your JIT access system with an Identity Provider like Okta, Google Workspace, Azure AD, or OneLogin, to serve as the single reliable source for identities. The advantage of rising or lowering individual identities over shared accounts is that it helps in better authorization control and optimum audit precision.

2. Execution.

• Self-serving access demands
  Make the process easier by letting users ask for access through the system, rather than through individuals. Boost adoption rates by integrating with IM platforms like Slack or MS Teams. Guarantee that requests detail who's asking, which service/resource/role is needed, duration, and the reason behind it.

• Approval procedure
  JIT access provides a chance for organizations to delegate approvals to individuals with business understanding. Resource owners and business unit managers usually have superior context than IT helpdesks. Use messaging platforms for speedy responses, equipping decision-makers with all necessary data for an informed verdict.

• Conditional approval workflows
  Incorporate your pre-determined policies into workflows that assess access permissions. Introduce them into workflows that dictate who can have access, to what extent and under what conditions. One effective strategy to implement this is by setting if-then conditions. (E.g., IF identity group “X” requests access to “Y”, seek approval from “Z” and notify “M”.).

• Integrations
  Think about integrating JITA with other IT and security systems to gain greater versatility; connect with IT ticketing systems for automated access depending on the status of the ticket. Incorporate with data classification systems to revise policies based on data sensitivity. Collaborate with an on-call schedule system for automated approvals during emergency situations. Connect with training systems to grant access upon completion of specific training.
• Automatic provisioning and retraction
  Understand Exabeam deeply in order to automatically grant and revoke access within the service efficiently. This is crucial for JIT Access as it reduces dependence on individuals.
• Access modes
  For Exabeam JIT Access, APIs are the best choice due to their adaptability and real-time sufficiency. However, a mixed approach may be necessary. For instance, using SAML for authentication, SCIM for user provisioning, and APIs for specific access control decisions.

3. Maintenance.

• Regular checks
  Periodically review access logs to ensure that JIT access is functioning as expected. Look for any unusual patterns or behaviors either directly or by merging the logs into your SIEM.
• User coaching
  Train users, especially those with special access, about the importance of minimum privilege, JIT Access and its functioning. Guarantee that users know how to ask for access when required.
• Feedback loop
  Review your JIT access procedures constantly. Ask for feedback from users and IT staff to understand where improvements are needed.

By using this systematic method, you'll be capable of effectively implementing a robust Just-in-Time Access system for Exabeam.
