We will introduce the concept of authorized points . For this kind of points we will try to develop a technique to avoid the inherent insecure nature of the Ethernet topologies. We will implement a solution that is almost port bridging without its hardware requirements. Then we will introduce another type of points. Computers are everyday more important in teaching and educational purposes.
Some teachers have their own laptop computer, with an ethernet adapter.
This laptop is used to teach classes. These network points at the classrooms are potential security holes. Only authorized users with authorized machines will be able to use that point. In addition to teaching, the University means also studying. So we have developed a system for our students to connect their laptops to our network access points in the libraries.
