I am working as a junior support engineer in University of Melbourne where my roles and responsibilities are to monitor the network and troubleshoot the problems in better manner. In present in university I found that most of the students and staffs members faced problems such as slow responding application and slow network connection. Moreover when they started the computer then it shows it busy trying to connect network.

In addition to this in university, where there are multiple clients (including both staffs members and students) on this network, they suffered from the problems such as inability to reach particular website. Moreover, the network issues become more complicated because a trust problem can arise between the management and students. In addition to this the problem also impacts the usability of internet technology in most of the application software. Denial of service attack also accesses both students as well as staffs member’s personal information and steals them for its own purpose. The main problem is listed below;
