Wireless Penetration Test

Wireless Penetration Test

Introduction

Wi-Fi or Wireless LAN is convenient and often necessary for connecting mobile devices to the network. It is also often an easy way for local attackers to gain access to the corporate networks. A Wireless Penetration Test can help uncover security weaknesses in your official wireless networks, and also help identify rogue or unauthorized WiFi devices.

What do we cover?

Our wireless penetration tests typically cover the following attack targets:

  • Your official, authorised Wi-Fi networks
  • Rogue or unauthorised Wi-Fi activity within the building
  • Wireless clients including mobile devices, laptops and VoIP equipment
  • Guest network access segmentation from corporate network

The following are some of the techniques that are typically employed in a Wi-Fi pentest:

  • Wireless survey to identify equipment in use
  • Breaking of WEP if still in use (common in hidden legacy networks)
  • Breaking of shared keys for WPA and WPA2
  • Bypassing of MAC filtering and identification of hidden SIDs
  • WPA Enterprise wireless cracking techniques
  • Once network access is achieved, tests are done to identify the security impact of such access

How does the process look like?

Most of our engagements follow these steps:

  1. First step is that you contact us
  2. We ask you a number of questions to understand what you have in mind, the goals for the exercise and the scope
  3. We perform a scoping exercise to better understand the size of the project; in the case of a wireless penetration test, the scoping exercise often questionnaires to better understand the exposure and therefore tailor our proposed work to your needs
  4. We verify with you our scope where appropriate
  5. We work on a proposal which describes the goals, the scope, the methodology, deliverables, dates allocated for the project, terms and conditions and the price
  6. The actual work takes place during the allocated dates; your IT staff involved in the project often need to be available during the tests
  7. Upon completing the tests, we work on the reports and often provide a brief report of the main findings so that your staff are informed of the results immediately
  8. The deliverables are provided to you
  9. Often the process also includes testing of the security fixes once applied

What are the deliverables?

At the end of the project, the client usually receives the following:

  • Executive report, which is an easy to follow 4 page report that includes information about the penetration test, list of the findings and a short explanation of the security fixes or mitigation techniques
  • Technical report, which includes the following sections:
    • Introduction, which describes the scope, methodology and purpose of the work
    • Methodology, which describes our tests to explain what was covered and how; this would include both tests that led to vulnerability discoveries, and also those that did not
    • Findings and recommendations which are categorised as High security threats, Other security threats and Other concerns and recommendations
    • Each finding that is considered a security threat includes:
      • A description of the security issue as it affects the target system
      • Our assessment of the impact of the vulnerability
      • Details on how to reproduce the issue found
      • Solutions and recommendations, which are tailored for the target audience and can go into quite some detail
  • Other material is sometimes provided such as:
    • Video demonstrations showing exploitation of your systems
    • Dedicated exploit code to reproduce the security issues found
    • Training can be provided

What costs can one expect?

Cost is dependent on the size and complexity of the system on test and the level of rigor in which testing is to be performed. This is determined through pre-sale client discussions and scoping questionnaires. The price of an engagement will be delivered as a fixed bid quote.
