Windows Security Event Codes, also known as Event IDs, are numeric codes that are used to identify specific events in the Windows event logs that are related to security. These codes are generated by the Windows operating system and can be used to track and troubleshoot security-related issues.
Each event code corresponds to a specific type of event, such as a successful login, a failed login attempt, or a security policy change. Some event codes are generated by the Windows operating system itself, while others are generated by third-party security software.
Event codes are typically displayed in the Windows Event Viewer, which is a tool that allows to view and manage event logs on a Windows system. The Event Viewer can be used to filter and sort events based on event codes, making it easier to locate and troubleshoot specific security issues.
Some common Windows Security Event Codes include:
- 4624 - Successful account logon
- 4625 - Failed account logon
- 4634 - User logoff
- 4648 - A logon was attempted using explicit credentials
- 4768 - A Kerberos authentication ticket was requested
- 4769 - A Kerberos service ticket was requested
- 4771 - Kerberos pre-authentication failed
- 4776 - The domain controller attempted to validate the credentials for an account
- 4798 - A user’s local group membership was enumerated
- 5140 - A network share object was accessed
The full list is collected in WindowsSecurityAuditEvents.xlsx and in the list below.
