Basic Networking (2020)
From CyberEdWiki
The intent of the Basic Networking Knowledge Unit is to provide students with basic understanding of how networks are built and operate, and to give students some experience with basic network analysis tools. Students are exposed to the concept of potential vulnerabilities in a network.
Contents
Outcomes[edit]
After completing the KU, students will be able to:
- Formulate the fundamental concepts, technologies, components and issues related to communications and data networks.
- Design a basic network architecture and vulnerabilities given a specific need and set of hosts/clients.
- Track and identify the packets involved in a simple TCP connection (or a trace of such a connection).
- Employ monitoring tools to observe the flow of packets (e.g., WireShark).
- Perform network mapping (enumeration and identification of network components) (e.g., Nmap).
Topics[edit]
- Networking models (OSI and IP).
- Network media (wired, optical, and wireless)
- Network Architectures and topologies (PAN, LAN/WAN, DMZ, Enclaves, VLAN, NAT, subnetting, supernetting)
- Common Network Devices and their role in the network. (Routers, Switches, Hosts, VPNs, Firewalls)
- Network Protocols introduction (IP, TCP, UDP, ICMP)
- Network Services and protocols introduction (DNS, NTP, VLAN, etc.).
- Network Applications and protocols introduction (SMTP, HTTP, VoIP, SSH, etc.).
- Use of basic network administration tools.
- Overview of Network Security Issues
Skills[edit]
- Install and configure computer network connections and networking components.
- Apply proper addressing (IP, Network, subnet, default route).
- Enable and configure network services (DNS, DHCP, etc.)
- Test connectivity (ping, traceroute, etc.)
- Apply Wireshark, or equivalent, to capture and view network packets.
- Identify the packets of a specific TCP session.
- Use a tool, such as nmap, to identify the devices and open ports on a network.
- Identify and close unneeded open ports.
- Troubleshoot basic network problems.
