Development and Implementation of the Access Matrix for Information Systems

Розробка та впровадження матриці доступу до інформаційних систем

Access rights are one of those things that companies rarely manage systematically. Access is granted “on request”, accumulates over years, and is often not revoked after employees leave. The result: former employees can still log into corporate systems, contractors have access to sensitive data, and nobody knows who actually has access to the CRM, ERP, or internal portal.

This is not a hypothetical threat. Implementing the Least Privilege principle and a role-based access model (RBAC) significantly reduces the attack surface and the risk of insider incidents.

We conduct a full audit of current access rights, develop a role model aligned with the company’s real structure and processes, implement the access matrix, and automate onboarding and offboarding processes. The result: everyone knows what they have access to and why — and it is all documented.

What we will do:

  • Audit of current access rights across all corporate systems
  • Identification of excessive and incorrect permissions, unused accounts
  • Development of a role-based model (RBAC) aligned with the organisational structure
  • Implementation of the Least Privilege principle
  • Development and documentation of the responsibility and access matrix
  • Automation of access provisioning and revocation processes (onboarding/offboarding)
  • Recommendations on IAM tools and integration with Active Directory/Azure AD
  • Training of HR and IT teams on new processes

Result:

✔ Full transparency: who has access to what and why — fully documented
✔ Compliance with GDPR, SOC2, ISO 27001 and auditor requirements
✔ Significant reduction in the risk of insider threats and data leakage
✔ Fast and controlled onboarding of new and offboarding of former employees
✔ Reduced IT department workload through automated processes

Do you know which of your employees has access to which systems right now? If not — this is not just an inconvenience, it is a risk. We will structure access rights and ensure full transparency. Check whether your company has unauthorised access risks. Submit a request for the service.
