1. Planning.

• Assessment
  Begin by recognizing who needs access, the resources they need, and why they need it. Take note of existing access privileges and assess if they can be minimized or even removed. The use of an entitlement discovery tool could provide increased understanding of these details.
• Policy creation
  Build clear models for both the granting and removal of access. Make sure to include guideposts for who can request access, when, and for what period of time. For roles with privileged permissions, create time-limited specifications.
• Source of truth
  Integrate your JIT access system with an Identity Provider (i.e., Okta, Google Workspace, Azure AD, OneLogin). This synchronization will serve as the absolute verification source for identities. By escalating and deescalating individual identities rather than shared accounts, authorization control is enhanced and auditing accuracy is improved.

2. Execution.

• Self-serve access requests
  To make the process easier, allow users to request access through the system itself, not through staff members. By integrating with messaging software like Slack or MS Teams, user adoption rates can be boosted. Requests should include the person making the request, the required service/resource/work area, how long it will be needed, and why.

• Approval process
  The JIT access tool provides an opportunity for businesses to delegate approvals to individuals with a deeper business understanding. Resource holders and business unit leaders often have more context than IT service desks. Use messaging applications for quick responses, supplying approvers with the essential information for an informed choice.

• Conditional approval workflows
  Apply your preset policies within the workflows that decide access rights. These can be instilled into processes which dictate who can access which resource, under what circumstances. An efficient way of doing this is by using if-then scenarios. i.e., IF identity group “X” requests access to “Y”, then approval from “Z” is required and “M” must be informed.

• Integrations
  By integrating JIT access with other IT and security systems, variety is increased. Consider linking with IT ticketing systems for automated access based on ticket status. Associate with data classification systems to modify policies as per data sensitivity. Tagging resources and bundling them together can simplify this process. Align with on-call schedule software for automated approvals during emergencies. Use training systems to grant access based on completed lessons.
• Automated provisioning and deprovisioning
  Developing an understanding of HackerRank is key in effectively providing and withdrawing granular access automatically within the service. This is crucial for JIT Access because it reduces the dependency on waiting for people to make time. It allows for the automated removal of access which facilitates JIT access and the principle of least privilege access (POLP). Ideally, you should manage all permissions in a central place not needing to build or manage a different environment for each application in your organization.
• Access methods
  For HackerRank JIT Access, APIs are preferable due to their flexibility and real-time capabilities. Nonetheless, a combination may be necessary. You could use, for instance, SAML for validation, SCIM for user provisioning, and APIs for accurate access control decisions.

3. Maintenance.

• Regular audits
  Periodically check access logs to ensure JIT access is operating as expected. Search for any unusual trends or behavior either directly or through your SIEM. Automating the user access review process expedites evidence gathering, delegates reviewers, and ensures your system adheres to relevant industry rules or norms.
• User training
  Users, especially those with privileged permissions, need to understand the importance of least privilege, JIT Access and the way it functions. Make sure users know how to apply for access when required.
• Feedback loop
  Incorporate regular reviews of your JIT access methods. Request feedback from users and IT personnel to understand how enhancements can be implemented.

By utilizing this structured method, you will be able to effectively put in place a durable Just-in-Time Access system for HackerRank.
