• Define and implement a clean, compliant target state for identity and access management (IAM), aligning AD and Entra ID security with enterprise IAM processes and governance.
• Conduct threat modelling and exposure assessments for both AD and Entra ID to identify and mitigate identity attack paths.
• Implement and maintain Tier 0 (Privileged Access) controls aligned with Microsoft’s Enterprise Access Model (EAM) and Zero Trust principles.
• Harden AD forests, domains, and trust relationships, as well as Entra ID tenants, to prevent privilege escalation, domain compromise, and lateral movement.

• Develop and maintain PowerShell and Graph API automation frameworks to:
• Audit and report AD and Entra ID configurations, permissions, and delegations.

• Manage and secure Organizational Unit (OU) delegation models and Entra ID administrative units following least-privilege principles.
• Manage and harden Group Policy Objects (GPOs) and Conditional Access Policies to enforce security baselines and prevent policy abuse.

• Collaborate with Red Team, Penetration Testing, and SOC teams to identify vulnerabilities, validate attack paths, and remediate exposures.
• Simulate and analyse identity-based attack scenarios (e.g., DCSync, DCShadow, Golden/Silver Ticket, Pass-the-Hash, Kerberoasting, token replay, and consent phishing).
• Integrate Threat Detection and Response capabilities within SOC operations and SIEM tools (e.g., Microsoft Sentinel, Splunk, QRadar).
