Monitoring with PowerShell Chapter 3: Monitoring Modern Authentication

Kelvin Tegelaar | 05 Aug, 2019 | 2 Mins Read

Modern Authentication is turned on by default for new tenants, but if you have legacy tenants or take over tenants from others MSP’s than sometimes you might have tenants that do not use Modern Authentication yet.

Monitoring and auto remediation is key in this when using Multi factor Authentication. We want the best user experience, so we must have it enabled to make sure users get a nice looking pop-up in outlook. also we want to avoid using App Passwords.

PowerShell Monitoring script:

This script only monitors the Modern Auth status, and does not auto-remediate.

$creds = get-credential
Connect-MsolService -Credential $creds
$clients = Get-MsolPartnerContract -All

foreach ($client in $clients) {
 $ClientDomain = Get-MsolDomain -TenantId $client.TenantId | Where-Object {$_.IsInitial -eq $true}
 Write-host "Logging into portal for $($client.Name)"
 $DelegatedOrgURL = "https://ps.outlook.com/powershell-liveid?DelegatedOrg=" + $ClientDomain.Name
 $ExchangeOnlineSession = New-PSSession -ConnectionUri $DelegatedOrgURL -Credential $credential -Authentication Basic -ConfigurationName Microsoft.Exchange -AllowRedirection
 Import-PSSession -Session $ExchangeOnlineSession -AllowClobber -DisableNameChecking

 $Oauth = Get-OrganizationConfig

 if($Oauth.OAuth2ClientProfileEnabled -eq $false){ $ModernAuthState += "$($ClientDomain.name) has modern auth disabled"}

 Remove-PSSession $ExchangeOnlineSession
}

if(!$ModernAuthState){ $ModernAuthState = "Healthy"}

PowerShell auto-remediation script

$creds = get-credential
Connect-MsolService -Credential $creds
$clients = Get-MsolPartnerContract -All

foreach ($client in $clients) {
 $ClientDomain = Get-MsolDomain -TenantId $client.TenantId | Where-Object {$_.IsInitial -eq $true}
 Write-host "Logging into portal for $($client.Name)"
 $DelegatedOrgURL = "https://ps.outlook.com/powershell-liveid?DelegatedOrg=" + $ClientDomain.Name
 $ExchangeOnlineSession = New-PSSession -ConnectionUri $DelegatedOrgURL -Credential $credential -Authentication Basic -ConfigurationName Microsoft.Exchange -AllowRedirection
 Import-PSSession -Session $ExchangeOnlineSession -AllowClobber -DisableNameChecking

 $Oauth = Get-OrganizationConfig

 if($Oauth.OAuth2ClientProfileEnabled -eq $false){ Set-OrganizationConfig -OAuth2ClientProfileEnabled $true }

 Remove-PSSession $ExchangeOnlineSession
}

And that’s it! Hope it helps and as always, Happy PowerShelling.

CyberDrain CTF returns! (and so do I!)

It’s been since september that I actually picked up a digital pen equivalent and wrote anything down. This was due to me being busy with life but also my side projects like CIPP. I’m trying to get back into the game of scripting and blogging about these scripts. There’s still so much to automate and so little time, right? ;)

Intro

This is a monitoring script requested via Reddit, One of the reddit r/msp users wondered how they can monitor Acronis a little bit easier. I jumped on this because it happened pretty much at the same time that I was asked to speak at the Acronis CyberSummit so it kinda made sense to script this so I have something to demonstrate at my session there.

Intro

Wow! It’s been a while since I’ve blogged. I’ve just been so swamped with CIPP that I’ve just let the blogging go entirely. It’s a shame because I think out of all my hobbies it’s one I enjoy the most. It’s always nice helping others achieve their scripting target. I even got a couple of LinkedIn questions asking if I was done with blogging but I’m not. Writing always gives me some more piece of mind so I’ll try to catch up again. I know I’ve said that before but this time I’ll follow through. I’m sitting down right now and scheduling the release of 5 blogs in one go. No more whining and no more waiting.
