Nowdays, the development of computer networks and Internet access is a process that involves an increasing number of technologies, and keeps spreading continuously.

The newly invented different kind of devices, architectures, protocols give much more options in networking than before, but not without drawbacks. New solutions all bring their vulnerabilities with themselves making the upkeep of steady functionality a more difficult task.

With the appearance of wireless network technologies, security issues and the supervision of traffic and resources became more challanging, than in case of the usual wired networks. Though many advantages the shared radio medium has, the arising questions of safety are numerous as well.

There are multiple wireless network technologies in common use, one of them are Mesh networks, which are getting more and more popular this days. It is an ad-hoc method based on flexible configuration options and dinamically changing topology according to actual demands. However, flexibility comes with the requirement of additional security arrangements and solutions.

One of the most popular tools of network security are Intrusion Detection Systems. They primary role is monitoring and analyzing traffic, detecting attacks almost real-time and generating alerts of them, thus supporting countermeasures.

In my thesis I’m going to present an overview of the Mesh and intrusion detection technologies, including their main features, benefits and drawbacks, and I will give a detailed solution of how to make them work together.
