Level 4: Cybersecurity Learner - Level 3
The MSAF (System Administration Fundamentals) certification from Mossé Cyber Security Institute validates my ability to architect, manage, and defend enterprise infrastructure. With 104 training exercises completed, this program emphasizes “Secure by Design” principles across Windows and Linux environments, virtualization, and disaster recovery.
Primary Infrastructure Solutions: GPO Security Engineering · Linux/Windows Hardening · Business Continuity (BCDR)
Strategic Administrative Capabilities
Leveraging the rigorous technical training from MSAF, I provide the following essential infrastructure services:
- Enterprise GPO Engineering: Deploying advanced Group Policy Objects to enforce UAC hardening, Exploit Guard, and strict account lockout policies.
- Network & Perimeter Defense: Designing organizational networks via Cisco Packet Tracer and securing perimeters using PFSense firewalls and OpenVPN links.
- Multi-Platform Administration: Managing server fleets using secure administration tools like Webmin and Cockpit, restricted by granular IP whitelisting.
- Disaster Recovery & Resilience: Engineering automated backup workflows using Duplicati and Active Directory restoration procedures to ensure business continuity.
