What is Windows “Security Event Logs”?

Microsoft Windows logs all the activities in the system on either the software or hardware. These logs are crucial for system security as they contain all the applications, security, DNS server, file relocation, and security logs.

A security log includes the following information:

  • Device Audit Policy
  • Login Attempts
  • Resource Access

The “Device Audit Policy” is a set of instructions determining which activities should be tracked and stored in a device’s security log. It can record login attempts and resource access in the security log. “Login Attempts” track any login activities, while “Resource Access” tracks any attempts to access or modify system resources. By checking the security log for these events, you can detect suspicious activities that may pose security risks and take necessary steps to prevent them.

The “Security Event Log” maintains the security-related information, including the suspicious activities that could harm the system. For example, repeated failed login attempts could indicate a hacking attempt; likewise, unauthorized access to sensitive files could suggest a potential data breach.

  • A Unique Event ID.
  • The Source From Where the Event was Generated.
