I am trying to write a script which collects security log from all of our domain controllers hourly and stores them remotely; i can collect the security logs , but is there a way to collect the security logs by category or event number from the DC? please do let me know if any additional questions.

My Code:

$Eventlogs = Get-WmiObject -Class Win32_NTEventLogFile -ComputerName $computer
Foreach($log in $EventLogs)
 {
        if($Log.LogFileName -eq "Security")
        {
            $Now = [DateTime]::Now
            $FileName = "Security" +"_"+$Now.Month+$Now.Day+$Now.Year+"_"+$Now.Hour+$Now.Minute+$Now.Second
            $path = "\\{0}\c$\LogFolder\$folder\$FileName.evt" -f $Computer
            $ErrBackup = ($log.BackupEventLog($path)).ReturnValue
            if($clear)
            { 
                if($ErrBackup -ne 0)
                {
                    "Backup failed" 
                    "Backup Error was " + $ErrBackup
                }
            }

        }
    }
         Copy-EventLogsToArchive -path $path -Folder $Folder 
}
