Cybersecurity Lab Exercises

Week Classroom Topic Textbook In-Class Lab Exercises
1 OSI and the Physical Layer
  • Chapter 1 – Introduction to Computer Networks
  • Chapter 2 – The Physical Layer

Workstation Utilities:

  • Students will use ipconfig, tracert, and other command-line utilities to identify and analyze network traffic.

Wireshark Capture:

  • Students will use Wireshark to identify network protocols and understand how to capture packets.
2 Data Link Layer
  • Chapter 3 – The Data Link Layer
  • Chapter 4 – The Media Access Control Sublayer

Ethernet Analysis:

  • Students will use Wireshark to capture a packet and analyze the structure and contents of an Ethernet frame.

ARP Analysis:

  • Students will use Wireshark and command-line utilities to analyze the messages related to the Address Resolution Protocol (ARP).
3 Network Layer
  • Chapter 5 – The Network Layer

Network Addressing:

  • Students will use command-line utilities and public websites to identify public and private IP address settings.

APIPA:

  • Students will use Windows networking utilities to obtain an Automatic Private IP Address (APIPA).
4 Network Layer (part 2)
  • Chapter 5 – The Network Layer (continued)

Router Settings:

  • Students will connect to classroom networking equipment to identify configuration settings.

Subnetting:

  • Students will connect to classroom networking equipment to configure IP subnets and Virtual LANs (VLANs).
5 Transport Layer
  • Chapter 6 – The Transport Layer

TCP Handshake:

  • Students will use Wireshark to capture a packet and analyze the Transmission Control Protocol (TCP) handshake.

Netstat:

  • Students will use the netstat command-line utility to display and analyze network connections.
6 Application Layer
  • Chapter 7 – The Application Layer

NMAP Scan:

  • Students will use the NMAP application to determine listening ports on a remote machine.

Netcat Usage:

  • Students will use the Netcat command-line utility to identify and analyze specific application layer protocols.
7 Network Security
  • Chapter 8 – Network Security

NMAP Scan II:

  • Students will use NMAP to scan a vulnerable target machine and determine open ports that provide a vector for compromise.

PKI:

  • Students will use command-line utilities to create and modify cryptographic keystores and trust stores.
