1. Planning.

• Assessment
  Begin by pinpointing those requiring access, the resources they need, and why. Assess current access rights and evaluate if they can be reduced or done away with. Think about using an entitlement discovery tool for more transparency.
• Policy development
  Establish lucid policies for both providing and withdrawing access. Formulate guidelines pinpointing who can request for access, under what scenarios, and for how long. Particularly for privileged roles, designate time-limited parameters.
• Source of truth
  Connect your JIT access system with an Identity Provider (for instance, Okta, Google Workspace, Azure AD, OneLogin). This will operate as the authoritative source for identities. De/escalating individual identities rather than shared accounts will result in improved authorization control and audit correctness.

2. Execution.

• Self-serve access requests
  Simplify the process by allowing the user to demand access through the system, not people. Improve adoption rates by joining with IM platforms like Slack or MS Teams. Assure that requests detail who is asking, the necessary service/resource/role, duration, and purpose.

• Approval procedure
  JIT access renders an opportunity for companies to delegate approvals to individuals in the know of the business context. Resource owners and business unit managers typically have superior context than IT helpdesks. Utilize messaging platforms for quick responses, furnishing approvers all needed information for an informed decision.

• Conditional approval workflows
  Incorporate your predetermined policies into workflows that regulate access permissions. Include them in workflows that manage who can access what, and under which conditions. An effective method is by assigning if-then conditions. IF identity group “X” asks for access to “Y”, seek approval from “Z” and notify “M”.

• Integrations
  Ponder on integrating JITA with other IT and security systems for extra flexibility; Integrate with IT ticketing systems for automated access rooted in the ticket status. Pair with data classification systems to adjust policies based on data discretion. Ideally, the ability to tag resources and group them together can streamline the process. Collaborate with on-call schedule software for automated approvals during emergencies. Use training systems to provide access based on training accomplishment.
• Automated provisioning and depovisioning
  Gain comprehensive understanding of Cerner to effectively offer and revoke fine-grained access automatically within the service. This is essential for JIT Access as it reduces dependence on waiting for people to take out the time. This allows for automated deprovisioning of access, pivotal for JIT access, and the principle of least privilege access (POLP). Ideally, you would handle all permissions in one place, not compelling to construct or manage an environment for each application in your enterprise.

3. Maintenance.

• Regular audits
  Occasionally inspect access logs to assure that JIT access is functioning as planned. Look for any unusual patterns or behaviors either directly or by feeding the logs into your SIEM. Automate the user access review process to speed up evidence collection, designate reviewers, and assure your system adheres to related industry regulations or standards.
• User training
  Educate users, particularly privileged users, about the importance of least privilege, JIT Access, and the way it functions. Verify users are aware how to request access when necessary.
• Feedback loop
  Ensure a regular review of your JIT access protocols. Seek feedback from users and IT staff to comprehend where improvements can be carried out.

By adhering to this structured approach, you will efficiently implement a sturdy Just-in-Time Access system for Cerner.
