function Get-SysmonProcessAccess { <# .SYNOPSIS Get Sysmon Access Procces EventLog Events (EventId 10). .DESCRIPTION Get Sysmon Process Access events either locally or remotely from a specified location. These events have an EventID of 10 and are for when a process acceses the memory space of a given process. .EXAMPLE PS C:\> Get-SysmonProcessAccess -TargetImage "C:\Windows\System32\lsass.exe" Check if any process has opened lsass.exe.
