The countermeasures to a buffer overflow are as follows:
* Perform manual auditing of the code.
* Stack execution should be disabled.
* Take the support of the functions which are not the cause of the buffer overflow.

By now, pretty much everyone has heard that it is easy to hack into WEP protected networks. As we have seen in our Cracking WEP article, it is terribly easy.
Most zero-day exploits in web applications are usually easier to find, study, and attack than actual services like a webserver due to the fact that a hacker does not need
Wi-Fi Protected Access (WPA and WPA2) is a class of systems to secure wireless (Wi-Fi) computer networks. It was created in response to several serious weaknesses researchers had found in
