About the assignment

Modern cybersecurity solutions rely on accurate detection rules within SIEM systems to identify potential threats. To maintain and improve these protections, it is essential that new rules are thoroughly tested before being implemented. In this internship assignment, you will investigate testing methodologies and develop a framework that supports the structured and efficient validation of new SIEM detection rules. Your solution should ensure each rule works as intended, while also verifying that existing system functionality is not negatively impacted. With this project, you will contribute to the robustness and quality of our cybersecurity offerings.
