Afternoon guys,
I'm working on going through some lockdowns for IIS, I need to add a Deny rule to .NET Authorizations for all anonymous users.
I have this, which partially works
Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT' -filter "system.web/authorization" -name "." -value #{accessType='Deny';users='?'}
? is an alias for All anonymous users
It partially works, as in it creates the rule, but it's set as an Allow Rule even though I'm calling Deny.
Does anyone have any ideas on how to get this to register as a Deny Rule?
I ended up finding the answer in the Related section off to the side. Don't know why this never popped up in my initial googling.
Managing IIS .Net Authorization Rules with a powershell script
My final code is
Add-WebConfigurationProperty -pspath 'MACHINE/WEBROOT' -filter "system.web/authorization" -name "." -value #{users='?'} -Type 'deny'

I'm including a Powershell script in my WixToolset installer to do various tasks in IIS, and I can't figure out one thing.
My Site in IIS is structured like this:
Sites
Default Web Site
WebApp1
WebApp2
Identity
I am able to set applicationDefaults.preloadEnabled to true on Default Web Site, but I only want to set preloadEnabled on my Identity WebApplication.
With limited Powershell knowledge, I've tried:
Import-Module WebAdministration
Get-WebApplication
Get-WebApplication "Identity"
The code above lists the Identity WebApplication correctly.
cd C:\inetpub\wwwroot
Set-ItemProperty "Identity" -Name applicationDefaults.preloadEnabled -Value True
The code above gives the error:
The property string applicationDefaults.preloadEnabled=True does not exist or was not found.
At line:1 char:1
I've also tried preloadEnabled instead of applicationDefaults.preloadEnabled, same result.
figured it out thanks to the comment from #guiwhatsthat and some extra searching. This is what worked.
Set-ItemProperty "IIS:\Sites\Default Web Site\Identity" -Name preloadEnabled -Value True
I am trying to create a script for our AAR-server that should create webfarms and the corresponding url rewrite rules. The script will try to delete the rule before creating it and in my case the rule does exist, but it won't find it:
WARNING: Target configuration object 'system.webServer/rewrite/globalRules/ARR_dst.test.refusjon-
8083_lb is not found at path 'MACHINE/WEBROOT/APPHOST'.
Is there any way to "browser" the path in IIS in order to verify if it does really exisit in path 'MACHINE/WEBROOT/APPHOST'. I assume so based on all the examples I have found on, but still - not sure on my installation.
So how to find the path to all rules?
Clear-WebConfiguration -pspath $psPath -filter $filterRoot
Add-WebConfigurationProperty -pspath $psPath -filter "system.webServer/rewrite/globalRules" -name "." -value #{name=$ruleName;patternSyntax='Regular Expressions';stopProcessing='False'}
Best, or, only thing I've found so far is to use the configuration editor and "Generate scripts"
Using Configuration Editor: Generate Scripts
Can I toggle these security settings using Powershell? I was hoping I could run a simple script to do it, since it must be applied to hundreds of computers
Set-Location HCKU:
Set-ItemProperty -Path 'SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings' -Name SecureProtocols -Value 2688
This enables all 3 TLS protocols.
Thanks f6a4 for pointing me in the right direction
I'm trying to set a user account as the Anonymous identity for a website authentication, and I've looked through every page on my Google searches but haven't found anything. There's a few things about setting it as the pool identity which is where I got the below line, but I'm not sure how that line is setting the pool identity, and I've tried to modify it to set the user account I want, but it's not working:
set-webconfigurationproperty /system.webServer/security/authentication/anonymousAuthentication -name UserName -value "domain\user" -Location "iis:\Sites\$NewApp"
I'm also trying to set a binding after I create a site, but the binding isn't being applied correctly, and I can't see why. I've looked at many examples online and tried to mimic what they have. I'm sure I just have a formatting error or something small like that. This is my binding line:
New-Item IIS:\Sites\$NewApp -bindings #{protocol="http";bindingInformation=$NewIP+":80"} -physicalPath "E:\Physicalpath"
I've spent 2 hours on this tonight, and it's driving me crazy. I just broke down and configured the servers manually for those couple items, but I really want to get this working so I can use it for other site creation scripts.
Thanks in advance for any assistance.
I was able to set the user, needed to add -PSPath. You should be able to combine -PSPath and -Location as per the Link: Enable authentication for IIS app in Powershell
set-webconfigurationproperty /system.webServer/security/authentication/anonymousAuthentication -name userName -value "domain\user" -pspath iis:\ -Location "iis:\Sites\pwa"
Further, you second doubt is clarified here: Examples of IIS Powershell cmdlets
From the above link:
COMMAND Examples: When -Value parameter is used by IIS powershell cmdlet, it usually set with a single string value (NOTE: if
the value contains space, it should be quoted with " or ')
The value can be hash table object if it is used to set a collection item
add-webconfiguration
'/system.applicationHost/sites/site[#name="Default Web
Site"]/bindings'-value #{protocol="http";bindingInformation="*:80:"}
-pspath iis:\
You can use Add-WebConfiguration for setting bindings, like so:
Add-WebConfiguration '/system.applicationHost/sites/site[#name="pwa"]/bindings' -Value #{protocol="ftp";bindingInformation="10.0.0.100:21:pwa.fabrikam.local"} -PSPath iis:\
Or, you can use Set-WebConfiguration for modifying:
set-WebConfiguration '/system.applicationHost/sites/site[#name="pwa"]/bindings' -Value #{protocol="https";bindingInformation="*:443:pwa.fabrikam.local";sslFlags=0} -PSPath iis:\
Adding everything via variables. You can manage your variables it suites your needs, I've separated every components of bindings into various variables. Putting variables inside bracket helps evaluating expressions.
$siteName = "pwa"
$appFilter = "//system.applicationHost/sites/site[#name='$($sitename)']/bindings"
$newIP = "*"
$port = 80
$hostName = "pwa.fabrikam.local"
$bindings = #{
protocol = "http"
bindingInformation="$($newIP):$($port):$($hostName)"
}
set-WebConfiguration -Filter $appFilter -Value $bindings -PSPath iis:\
If you now change only variables, the commands should continue to function. I tried changing IP and ports via variables $newIP and $port. Let us know how it goes.
I'd like to simply add some .Net Authorization rules in IIS (7.5 / win 2008 R2) using a powershell script with PS snap in. So far I was able to add some "allow" rules but not any deny ones.
Each time I try, it either does nothing or creates an "allow" rule, which seems odd, like if it was defaulting to allow all the time.
I tried with add-webconfigurationproperty and add-webconfiguration with no luck.
Maybe one of you has the correct command line to use?
For instance:
Add-WebConfiguration "/system.web/authorization" -value #{ElementTagName="Deny";users="*"} -PSPath "IIS:\Sites\Mysite"
Add-WebConfigurationProperty "/system.web/authorization" -Name "collection" -value #{ElementTagName='deny';users='test'} -PSPath "IIS:\Sites\Mysite"
will create 2 "allow" rules.
Same behavior if I remove ElementTagName='deny'. So weird. Like if the deny "mode" was to be accessed in some different way.
And for instance, if I go to IIS 8 and try to generate the script after adding a deny rule, the command line suggested is not working either.
How can I fix this?
The command you should use to add a deny rule in your example is:
Add-WebConfigurationProperty "/system.web/authorization" -PSPath "IIS:\Sites\Mysite" -Name "." -value #{users='test'} -Type "deny"
This bothered me too & I also had trouble getting appcmd to do the same thing. I did get it working in the end & found that the -Type parameter was the important one. This wasn't all that clear to me from the documentation which just says:
The type of property to add.
