1. Planning.

• Assessment
  Begin by identifying those who necessitate rights to LastPass, the resources they require, and the justification. Document existing access rights and assess whether they can be minimized or abolished. Consider deploying an entitlement discovery tool for enhanced visibility.
• Policy creation
  Establish decisive policies for both granting and rescinding of access. Frame guidelines about who can solicit access, under what conditions, and for what duration. Particularly for high-privilege roles, define time-specific parameters.
• Source of truth
  Synchronize your JIT access system with an Identity Provider (such as, Okta, Google Workspace, Azure AD, OneLogin). This will serve as the final word of authority for identities. Individual identity elevation or lowering over shared accounts will enable better control of authorization and accurate auditing.

2. Execution.

• Self-serve access requests
  Streamline the process by having users solicit access through the system, rather than people. Integrate with IM platforms like Slack or MS Teams to boost adoption rates. Ensure requests specify who's soliciting, the required service/resource/role, duration, and reason.

• Approval process
  JIT access provides an opportunity for organizations to delegate authorizations to individuals with business context. Resource owners and business unit managers generally have better context than IT helpdesks. Use instant messaging platforms for quick responses, providing approvers with all necessary detail for a well-informed decision.

• Conditional approval workflows
  Embed your predefined policies into workflows that decide access permissions. Place them into workflows governing who can access what, and under what conditions. An effective method could be designating if-then conditions.  IF identity group “X” requests access to “Y”, seek approval from “Z” and inform “M”.

• Integrations
  Look at integrating JITA with other IT and security systems for additional flexibility. Integrate with IT ticketing systems for automated access contingent on ticket status. Link with data classification systems to adjust policies depending on data sensitivity. Consider on-call schedule software for emergencies automated approvals. Use training systems to grant access based on training completion.
• Automated provisioning and deprovisioning
  Have a thorough understanding of LastPass to effectively provide and revoke fine-grained access automatically. Automated deprovisioning of access is a core aspect of JIT access and the principle of least privilege (POLP). Ideally, all permissions should be managed in one place, rather than creating or managing individual environments for each application.
• Access methods
  APIs are preferable for LastPass JIT Access due to their adaptability and real-time capabilities. However, a combination might be necessary. SAML for authentication, SCIM for user provisioning, and APIs for precise access control decisions could be used as such.

3. Maintenance.

• Regular audits
  Periodically scrutinize access logs to ascertain that JIT access is functioning correctly. Detect any irregular patterns or activities either directly or by feeding the logs into your SIEM. You can automate user access review processes to accelerate evidence gathering, delegate reviewers, and ensure system compliance with relevant regulations or standards.
• User training
  Illuminate users about the importance of least privilege, JIT Access, and its workings. Ensure users are aware of how and when to request access.
• Feedback loop
  Consolidate consistent review of your JIT access procedures. Seek views from users and IT staff to detect areas for betterment.

With this structured approach, you'll efficiently implement a robust Just-in-Time Access system for LastPass.
