A Software System for Secure Computer Aided Exams

In this paper, a program is designed and implemented for exams which are taken in computer laboratories. The aim of the software is to overcome difficulties of such exams. Program mainly solves two important problems, which are preventing file sharing between client computers and collecting answer files from client computers. Program consists of two main parts, server part and client part. The server part is used by the instructor and the client part is used by students. The instructor uses the server part for managing student, course, exam data, and it is used for controlling the clients and activating them during the exam. Activated client blocks the network communication of the computer but it permits file transfer between the client and the server. Client includes a firewall system for controlling network packets and during the exam, the firewall blocks network traffic. This system provides a secure computer lab exam environment since student computer cannot access to local network and Internet. Students use client part’s user interface for uploading their files to server. After the exam instructor can easily access and evaluate the students’ uploaded files.
