In order to attack, you must first find a target, and though site surveys can make this easier, they cannot help in every case. Several tools and mechanisms make locating a target network easier. The following are methods that can complement wardriving or be used on their own: OpenSignal is a useful app that can … Read more
When you are authenticating clients to a wireless network, two processes are available. The first, known as open system authentication, is used in situations where you want to make your network available to a wide range of clients. This type of authentication occurs when an authentication frame is sent from a client to an access … Read more

No network discussion or network device explanation would be complete without a brief overview of the Open Systems Interconnection (OSI) model. Although this model may seem overly complex, it does have value in our later discussions of attacks, defenses, and infrastructure, as you will see. The OSI model is a general framework that enables network … Read more
Network infrastructure vulnerabilities are the foundation for most technical security issues in your information systems. These lower-level vulnerabilities affect practically everything running on your network. That’s why you need to test for them and eliminate them whenever possible. Your focus for security tests on your network infrastructure should be to find weaknesses that others can … Read more
The Institute of Electrical and Electronics Engineers (IEEE) created the 802.11b Standard to provide a secure architecture for communicating with networking devices over an air medium but the standard has fallen short in providing a secure criterion. The 802.11b Standard has left many doors open for hackers to exploit these shortcomings and the goal of … Read more
