ISACA Networks and Infrastructure Fundamentals (ITCA)

Network incidents often start with gaps in fundamentals: cabling, wireless, addressing, routing, remote access, and monitoring. This beginner-level ISACA ITCA course gives IT Directors and Team Leads a structured way to standardize baseline network knowledge across entry-level IT Practitioners, help desk staff moving toward network roles, and junior admins who support infrastructure under supervision.

The course is about 21 hours of training per learner, making it realistic to assign over several weeks alongside ticket work. It covers practical foundations such as physical and wireless connections, VPNs, VLANs, IPv4/IPv6 addressing, routing protocols, network services, cloud networking, AAA/RADIUS, monitoring, availability, and secure network design. For compliance-minded teams, it helps build shared language around controls, access, and network security—but it should be paired with organization-specific policies and procedures.

CBT Nuggets Playlists help Training Managers sequence this as role-specific onboarding, while Team Reporting helps IT leaders track completion and readiness across the team.

IT teams complete this training to reduce dependence on a few senior network specialists and give junior staff a safer foundation for day-to-day infrastructure support.

• Faster troubleshooting: Team members can distinguish physical, wireless, transport, routing, and service-layer issues before escalating.
• More consistent remote access support: Lessons on VPNs, AAA, RADIUS, and border network components help staff understand how secure connectivity fits together.
• Better change planning: Coverage of VLANs, SDN, addressing, static routes, dynamic routing, and network topologies helps teams discuss changes with less guesswork.
• Improved operational awareness: Monitoring, availability, performance, cloud networking, and secure design topics help junior practitioners recognize risks that can lead to outages or access issues.

Knowledge

• Network layers, connection types, and how physical, wireless, and virtual connections support infrastructure.
• Common network components, hybrid devices, border components, and enterprise network architecture models.
• IPv4 concepts including binary, hexadecimal, address classes, ANDing, plus IPv6 addressing and configuration basics.
• Transport protocols, static routes, dynamic routing protocols, and core network services.
• Secure networking concepts including VPNs, VLANs, AAA, RADIUS, directory services, and security-related network services.

Ability

• Identify where connectivity problems may exist across physical, wireless, routing, transport, or service layers.
• Discuss and support basic VLAN, VPN, IPv6, and routing configuration tasks under supervision.
• Explain how telework, virtual networks, cloud networking, and directory services fit into enterprise environments.
• Recognize the purpose of monitoring, management, availability, and performance controls.
• Apply foundational network security concepts when supporting infrastructure changes or escalations.
