DISA STIG (Manual Reference)

Universal method:
1. In the omnibox (address bar) type chrome://policy
2. If "NetworkPredictionOptions" is not displayed under the “Policy Name” column or it is not set to "2" under the “Policy Value” column, this is a finding.
Windows method:
1. Start regedit
2. Navigate to HKLM\Software\Policies\Google\Chrome\
3. If the "NetworkPredictionOptions" value name does not exist or its value data is not set to "2," this is a finding.

# OVAL Definition: oval:mil.disa.stig.chrome:def:240025
$regPath = "HKLM:\Software\Policies\Google\Chrome\NetworkPredictionOptions"
if (Test-Path $regPath) {
    $regValue = Get-ItemProperty -Path $regPath -Name NetworkPredictionOptions -ErrorAction SilentlyContinue
    if ($regValue -and $regValue.NetworkPredictionOptions -eq 2) {
        Write-Output "PASS"
        exit 0

}
Write-Output "FAIL"
exit 1
