Project history
As an IAM consultant in the global portal project I consult the migration of the on-premises Active Directory to the IAM solution EmpowerID and start using SAML and OIDC.
I have migrated the AD identities and roles to a new cloud based IAM system (EmpowerID). This included the unraveling of the existing authorsiations with custom AD objects, attributes an AZ-man delegations.
I have also prepared the existing objects for the cloud migration by removing diacritics and special characters in their usernames.

As part of the internal audit department performed audit engagements at local departments and vendors.
As a technical IT auditor, I tested the various infra components such as operating systems, database and applications of the engagement. By performing security scans and exploiting vulnerabilities.
Also performed red teaming exercises to determine weak spots and testing the effectiveness of the implemented security controls.
In addition, consulted departments on improving their security controls such as technical state compliancy, vulnerability management and security event monitoring.
