Windows Event ID 4892 – Microsoft-Windows-Kernel-General: System Time Change Detected
Event ID 4892 fires when Windows detects a system time change, typically during time synchronization, manual adjustments, or hardware clock drift corrections.
Windows Event ID 4890 – Microsoft-Windows-Security-Auditing: A handle to an object was requested
Event ID 4890 logs when a process requests a handle to a system object. This security audit event tracks object access attempts for compliance and security monitoring purposes.

Event ID 4888 from Kernel-Power indicates a system power state transition, typically logged when Windows enters or exits sleep, hibernate, or shutdown states during power management operations.
Windows Event ID 5028 – Windows Filtering Platform: Failed to Load Security Policy
Event ID 5028 indicates Windows Filtering Platform (WFP) failed to load security policy during system startup, potentially affecting firewall rules and network filtering capabilities.
Windows Event ID 4881 – Security: Certificate Services Template Security Permissions Changed
Event ID 4881 logs when security permissions on a Certificate Authority template are modified, indicating changes to who can request or manage specific certificate types in your PKI infrastructure.
Windows Event ID 4880 – Security: Certificate Services Template Security Permissions Changed
Event ID 4880 logs when security permissions on a Certificate Authority template are modified, indicating changes to who can request or manage specific certificate types in your PKI infrastructure.
Windows Event ID 4877 – Security-Auditing: Certificate Services Template Security Permissions Changed
Event ID 4877 fires when security permissions on a Certificate Authority template are modified. Critical for PKI security monitoring and compliance auditing in enterprise environments.
Windows Event ID 4876 – Security: Special Privileges Assigned to New Logon
Event ID 4876 records when special privileges are assigned to a new user logon session, indicating elevated access rights have been granted during authentication.
Windows Event ID 4872 – Microsoft-Windows-Security-Auditing: Certificate Services Template Security Permissions Changed
Event ID 4872 fires when security permissions on a Certificate Authority template are modified. This audit event tracks changes to certificate template access control lists and helps monitor PKI security modifications.
Windows Event ID 4871 – Microsoft-Windows-Security-Auditing: Certificate Services Denied Request
Event ID 4871 fires when Active Directory Certificate Services denies a certificate request due to policy violations, insufficient permissions, or template restrictions.
Windows Event ID 4870 – Kerberos: TGT Renewal Failure
Event ID 4870 indicates a Kerberos Ticket Granting Ticket (TGT) renewal failure, typically occurring when domain authentication encounters issues with ticket refresh operations.
Windows Event ID 4869 – Kerberos: Certificate Services Client Operation Failed
Event ID 4869 indicates a Kerberos certificate services client operation has failed, typically during certificate enrollment or renewal processes in Active Directory environments.
Windows Event ID 5378 – SCHANNEL: TLS/SSL Certificate Chain Validation Error
Event ID 5378 indicates SCHANNEL encountered a certificate chain validation error during TLS/SSL handshake, typically due to untrusted root certificates or incomplete certificate chains.
