***Event Description:***
|
|
|
|
This event generates every time [Authentication Package](https://msdn.microsoft.com/en-us/library/windows/desktop/aa374733(v=vs.85).aspx) has been loaded by the Local Security Authority ([LSA](https://msdn.microsoft.com/en-us/library/windows/desktop/aa378326(v=vs.85).aspx)).
|
|
|
|
Each time the system starts, the LSA loads the Authentication Package DLLs from **HKEY\_LOCAL\_MACHINE\\SYSTEM\\CurrentControlSet\\Control\\Lsa\\Authentication Packages** registry value and performs the initialization sequence for every package located in these DLLs.

**Authentication Package Name** \[Type = UnicodeString\]**:** the name of loaded [Authentication Package](https://msdn.microsoft.com/en-us/library/windows/desktop/aa374733(v=vs.85).aspx). The format is: DLL\_PATH\_AND\_NAME: AUTHENTICATION\_PACKAGE\_NAME.
|
|
|
|
By default the only one Authentication Package loaded by Windows 10 is “[MICROSOFT\_AUTHENTICATION\_PACKAGE\_V1\_0](https://msdn.microsoft.com/en-us/library/windows/desktop/aa378753(v=vs.85).aspx)”.
|
|
|
|
## Security Monitoring Recommendations
|
|
|
|
For 4610(S): An authentication package has been loaded by the Local Security Authority.
|
|
|
|
- Report all “**Authentication Package Name**” not equals “C:\\Windows\\system32\\msv1\_0.DLL : MICROSOFT\_AUTHENTICATION\_PACKAGE\_V1\_0”, because by default this is the only Authentication Package loaded by Windows 10.
|
|
|
|
- Typically this event has an informational purpose. If you have a pre-defined list of allowed Authentication Packages in the system, then you can check whether “**Authentication Package Name”** is in your defined list.
