Online exam systems are pieces of software used in online education to evaluate students’ performance. However, both the security of the system they respond to and a broad understanding of the risks they may face must be addressed. In this article, we will look into the most recent issue, which is online exams and their security systems. Because most students depended on Google, their friends, and other resources for help, we focused on software-based security and online support for cheating like IP address tracing, block local file accessing etc. We did this project step by step like collecting data, data pre-processing, data cleaning, training data and trying to make a prediction of how the student cheated the most. Then we can start our future work as we want to increase the security of online exams. According to the findings of a few study papers we read, individuals that use e testing do so for all main kinds of assessment, including quizzes, midterms, and final exams. The most common format for these tests is multiple-choice, which is certainly the easiest to cheat on, but the faculty admits they aren’t routinely employing anti-cheating tactics. So, this research paper will help the new world in the field of online exam systems.
