In this course, students perform a penetration test on a server by utilizing the tools in Kali Linux. Other vulnerability scanner programs (Nessus and OpenVas) are installed on Kali Linux to execute an automatic vulnerability assessment. Students gain access to the server and steal the passwords by exploiting the discovered vulnerabilities. Then, they try to crack the passwords. The test is conducted based on ethical hacking methodologies to have a systematic lane in order to bring better results. Legal and ethical standards respected throughout the practicals. Based on the results, counter measurements are generated and supported against the vulnerabilities. Finally, all the findings are explained and illustrated in an official report.
