CWSP Introduction

The CWSP Wireless LAN Security course consists of hands-on learning using the latest enterprise wireless LAN equipment. This course addresses in detail the most important and relevant WLAN security protocols, exchanges, and deployment strategies in the enterprise today. We focus heavily on understanding the functionality of the 802.11i amendment (now part of the larger standard), including authentication, encryption, and key management. 802.1X and EAP are also central to this conversation, with an in-depth examination of the inner-workings of each authentication mode and EAP type used in wireless LANs today. Other infrastructure security solutions are also taught, such as role-based access control, segmentation, VPNs, firewalls, wireless intrusion prevention and monitoring, secure roaming, and network management. Finally, no security course is complete without taking a look at security vulnerabilities, attacks, audit and penetration tools, as well as policy and prevention. We cover every type and class of WLAN security solution available on the market.

Upcoming classes:

    Sydney: 15-16 Nov
    Melbourne: 25-26 Nov

Students who complete the course will acquire the necessary skills for implementing and managing wireless security in the enterprise by creating Layer-2 and Layer-3 hardware and software solutions with tools from the industry leading manufacturers. This course is also designed to prepare attendees to take and pass the PW0-204 CWSP security exam.

CWSP Hands-on Lab Exercises

WLAN Connectivity

Along with client devices, WLAN access points and/or controllers are currently the center piece of 802.11 security. Other infrastructure components are important to security, but the primary focus is how client devices access the network, what authentication and encryption methods are used, and how that wireless data is protected. For this reason, an in-depth understanding how to secure access to the network through the WLAN infrastructure is essential.

This lab is focused on WLAN AP/controller and client device security, and primarily covers the following areas:

  1. Secure access to the AP/controller using secure management protocols
  2. Configuring multiple WLAN profiles, each with its own authentication and cipher suites including WPA/WPA2 Personal and Enterprise
  3. Configuring client devices to connect to the WLAN infrastructure using secure protocols including WPA/WPA2 Personal and Enterprise.
  4. Creating user or group policies that provide network services to clients based on their authorization level
  5. Understanding integrated wIPS configuration, policies, and monitoring

802.1X/EAP Configuration

This lab is focused on 802.1X/EAP security. WPA/WPA2-Enterprise relies on secure authentication via 802.1X/EAP, often utilizing an enterprise’s backend authentication infrastructure, including RADIUS servers as well as user databases. In this lab, we will gain first-hand knowledge of this process and the configuration details involved. This lab group covers the following exercises:

  1. Setting up a RADIUS server and a user credential database with EAP support
  2. Creating and using server certifications and installing the certification on client devices
  3. Configuring the WLAN AP/controller for 802.1X with RADIUS connectivity
  4. Configuring EAP types, user credentials, and certifications on the client devices

Wireless Intrusion Prevention Systems (WIPS)

This lab module is focused on Wireless Intrusion Prevention Systems (WIPS). WIPS are known for three overriding functions: security monitoring, performance monitoring, and reporting. In this lab exercise, we will focus on security monitoring and reporting. Areas of particular interest include:

  1. WIPS installation, licensing, adding/configuring sensors, and secure console connectivity
  2. Configuring WLAN profils according to organizational security policies
  3. Properly classifying authorized, unauthorized, and external/interfering access points
  4. Identifying and mitigating rogue devices
  5. Identifying specific attacks against the authorized WLAN infrastructure or client stations

Using Laptop-based Protocol and Spectrum Analyzers

This lab is focused on the use of laptop analyzers for spectrum analysis, protocol analysis, and WLAN discovery. Understanding driver issues, security-related protocol analysis (authentication and encryption), and spectrum analysis will aid the wireless security professional in policy compliance, proper implementation, and troubleshooting. The following steps will be covered in this lab exercise.

  1. Installing and configuring a WLAN discovery tool, a laptop protocol analyzer, and a laptop spectrum analyzer
  2. Locating and analyzing 2.4 GHz and 5 GHz WLANs with a WLAN discovery tool and protocol analyzer
  3. Capturing and analyzing WPA2-Personal and Enterprise (among others) authentication sequences in a WLAN protocol analyzer
  4. Capturing and analyzing Hotspot authentication and data traffic in a WLAN protocol analyzer
  5. Capturing and analyzing common frame types and security elements with a WLAN protocol analyzer
  6. Viewing a normal RF environment, a busy RF environment, RF interference sources, and an RF attack on the WLAN in a spectrum analyzer

Fast Secure Roaming

This lab is focused on fast secure roaming (FSR) within an Extended Service Set. Moving quickly and securely between access points attached to the same distribution system is a requirement of real-time mobility devices such as VoWiFi phones and mobile video devices. Understanding the standards-based and proprietary processes of a Fast Transition (FT) service will help network designers support strong security and fast roaming simultaneously. The following steps will be covered in this lab exercise.

  1. Configure a WLAN infrastructure roaming scenario with multiple APs and possibly multiple controllers
  2. Utilize a RADIUS server for 802.1X/EAP authentication and the WLAN infrastructure for simpler forms of security
  3. Configure a client device for EAP authentication using the CCMP cipher suite
  4. Configure an 802.11 protocol analyzer to capture the roaming transition
  5. Perform a slow BSS transition as a baseline, testing open authentication, WEP, WPA2-Personal, and WPA2-Enterprise
  6. Enable fast secure roaming mechanisms within the infrastructure and on the client station and perform a fast transition
  7. Conduct the same tests across a Layer-3 IP boundary as well as between controllers

Network Attacks and Auditing

This lab is focused on understanding and conducting common network attack sequences. Defensive network security requires an understanding of offensive attacks. Auditing is the process of validating a security solution, and understanding auditing tools is an important skill for administrators and consultants. This module will be tailored to the class, but covers topics like the following:

  1. Conducting authentication and encryption cracking attacks
  2. Conducting simple attacks/workarounds like MAC spoofing
  3. Performing basic protocol analysis and eavesdropping
  4. Attempting advanced attacks like session hijacking, packet injection, replay attacks, and protocol DoS attacks
