PowerShell script that would display the security of SharePoint Site

Question

I'm looking for a PowerShell script that would display or create a report of the security configuration of a site collection. Any help would be appreciated.

It would list:

• Site Collection Owners
• Each group and it’s owner
• Each group’s permission level
• Each permission level and which of the check boxes are checked.

PowerShell is ideal for this. You can use something like this get the information you want.

$siteUrl = "http://.." 
$site = Get-SPSite $siteUrl
$site.RootWeb.SiteAdministrators
$site.RootWeb.SiteGroups | Select Name, Owner, Roles
$site.RootWeb.RoleDefinitions | Select Name, BasePermissions

If you want to loop through all webapplication you could use code like

Get-SPWebApplication | Get-SPSite -Limit All | % {
    $site = $_
    $site.RootWeb.SiteAdministrators
    $site.RootWeb.SiteGroups | Select Name, Owner, Roles
    $site.RootWeb.RoleDefinitions | Select Name, BasePermissions
}
