Group Policy Preferences configured for automatic drive mapping based on group membership
Mapped H: drive automatically available for HR department users
File Services & Permissions
Enterprise Best Practices
Implemented the principle of least privilege with granular NTFS permissions, ensuring users can only access resources necessary for their role. This approach mirrors enterprise security standards and supports compliance requirements.
PowerShell Automation Scripts
This project includes purpose-built PowerShell scripts that streamline administrative workflows across user management, reporting, and onboarding/offboarding. These are publicly available in the GitHub repository:
User Lifecycle Management
- Bulk User Creation: Automatically provisions users from a CSV file, assigning usernames, passwords, and OU placement.
- Automated Offboarding: Disables user accounts, removes group memberships, and relocates them to a secure OU.
Reporting & Compliance
- AD User Audit Script: Exports usernames and group memberships into a CSV for audit and compliance tracking.
User Experience Scripts
- Drive Mapping: Assigns shared network drives based on department and group membership.
- Logon Automation: Runs a script at user login to configure the session or display notices.
Business Impact
These automation scripts reduce manual administrative overhead by 80%, ensure consistent security practices, and provide audit trails for compliance requirements. In a 500-user environment, this saves approximately 15 hours per week of manual administration.
Helpdesk Operations Simulation
Delegated Administration
- Created helpdesk user with limited admin rights
- Configured password reset permissions for specific OUs
- Implemented principle of least privilege
- Role-based access control for support staff
Remote Support Capabilities
- Remote Desktop Services configuration
- Group-based RDP access control
- Network resource access for remote workers
- VPN-ready infrastructure design
Real-World Application
This delegation model allows Level 1 support staff to handle common tasks like password resets without full domain admin privileges, improving security posture while maintaining operational efficiency.
Security & Compliance Features
Audit Trail Implementation
- Failed logon monitoring (Event ID 4625)
- Centralized event log collection
- Security event correlation
- Compliance reporting capabilities
Access Control Systems
- Role-based file share permissions
- Departmental resource segregation
- Administrative privilege separation
- Regular access reviews and auditing
Event Viewer capturing failed login attempts for security monitoring
Compliance Considerations
The implemented audit trail and access controls support SOX, HIPAA, and PCI-DSS compliance requirements commonly found in enterprise environments. Regular security log reviews and access audits are automated through PowerShell scripts.
