Windows Event Logs are an essential resource for system monitoring and security. This study investigates the critical role that Windows Event Logs and Event IDs play in identifying and security breaches on Windows systems. The goal is to demonstrate how Event IDs, which are contained within Event Logs, can be used to identify various security events. The investigation includes an examination of various sorts of security breaches, each of which is associated with a unique Event ID, clarifying their significance in breach detection. This paper highlights the importance of Event Logs in uncovering unauthorized access attempts, malware infections, elevated privileges, and other security flaws by providing methods for extracting, parsing, and analysing them. The practical application of Event IDs in real-world circumstances is demonstrated through case studies and examples, highlighting their efficacy in reinforcing system security.
