As the question basically says, is there a way to stop permissions inheritance on a list or a library via PowerShell?
Moreover there is a way to change user or group permissions on this list/library?
Thanks a lot!

Since SharePoint 2013/Online supports a sets of APIs, CSOM or REST APIs could be consumed in PowerShell for that purpose.
How to stop permissions inheritance for a List in SharePoint Online
Prerequisites: SharePoint Online Client Components SDK
The example below shows how to assign unique permissions for a list using CSOM API in PowerShell:
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client")
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Client.Runtime")
Function Get-ClientContext([string]$Url,[string]$UserName,[string]$Password)
{
$SecurePassword = $Password | ConvertTo-SecureString -AsPlainText -Force
$context = New-Object Microsoft.SharePoint.Client.ClientContext($Url)
$context.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($UserName, $SecurePassword)
return $context
}
Function List-BreakInheritance([Microsoft.SharePoint.Client.ClientContext]$Context,[string]$ListTitle)
{
$list = $Context.Web.Lists.GetByTitle($ListTitle)
$list.BreakRoleInheritance($true, $false)
$Context.ExecuteQuery()
}
$UserName = "[email protected]"
$Password = Read-Host -Prompt "Enter the password"
$Url = "https://contoso.sharepoint.com/"
$context = Get-ClientContext -Url $Url -UserName $UserName -Password $Password
List-BreakInheritance -Context $context -ListTitle "Tasks"
$context.Dispose()
As an alternative, you could also consider to utilize REST API.
Unfortunately this can't be done with PowerShell (yet). You have to use Office 365 API for this action.

1You could run CSOM from PowerShell also: sharepointnutsandbolts.com/2013/12/…Anders Aune– Anders Aune2015-05-12 11:00:10 +00:00Commented May 12, 2015 at 11:00
