Categories: Linux administration, Networking
Theory and practice of wireless networking (802.11 protocol family). Configuring WiFi on network devices and workstations. Security issues (authorization and encryption methods). As an exercise, participants learn how to eavesdrop on unsecured network traffic and break networks that use the vulnerable WEP protocol.
Duration
1 day
Agenda
- Introduction to wireless communication
- 802.11 standard and its variants. Medium characteristics, basic concepts: channel, power
- Connection types, point-to-point, point-to-multipoint
- Basic access point configuration
- Basic workstation configuration (Windows, Linux)
- Client roaming between multiple access points
- Wireless bridge configuration using WDS mode
- Basic security topics
- SSID
- MAC address filtering (and why it’s no good)
- Encryption mechanisms
- WEP
- WPA/WPA2, Enterprise and Personal (PSK)
- RADIUS server for Enterprise WPA
- Penetration testing tools, network scanners
- Breaking WEP encryption
Audience and prerequisites
This course targets at least intermediate-level network administrators.
Participants must have good knowledge of general network configuration on any operating system (protocol stack, routing, firewalls).
Certificates
Course participants receive completion certificates signed by ALX.
