Switching, Routing and Segmentation
Network Security Devices
Network Attacks and How to Detect Them
Hands-On: Traffic Analysis, Firewalls and Design
See Attacks Where They Happen
Learn how networks work, how they are attacked and how to defend them.
Course Overview
Almost every cyber attack travels across a network. This course gives you the networking knowledge that SOC analysts and network defenders use every day, from IP addressing and VLANs to firewalls, attack detection and Wireshark, with hands-on tasks you do on your own computer.
By the end, you will be able to:
- Explain the OSI and TCP/IP models, and the ports and protocols attackers target.
- Work with IP addresses, subnets and NAT.
- Use VLANs and segmentation to contain attacks.
- Explain how firewalls, IDS/IPS and VPNs protect a network.
- Spot the signs of sniffing, man-in-the-middle, scanning and DoS attacks.
- Analyze traffic in Wireshark, configure firewall rules and design a secure network.
