Renew an Azure DevOps Service Connection’s expired secret

    

We ran into an issue this morning where we needed to renew our Azure DevOps Service Connection’s expired secret but there is no officially supported way to do this. The error was AADSTS7000215 - invalid clientid or secret. Thankfully, it’s not that difficult to solve.

Fake a change

  1. Open your project in ADO (https://dev.azure.com/[GROUP]/[PROJECT])
  2. At the bottom-left, choose Project settings
  3. In the Pipelines section, choose Service connections
  4. Select the service connection you’re having issues with
  5. If you click the Edit Service Principal link, you should see a red warning at the top of the page stating that one or more secrets for this service principal have expired; you can verify this by clicking the Certificates and secrets link on the blade and seeing that the single secret expired in the past
  6. Close this tab
  7. Click the Edit button
  8. You’ll notice there is no visible way to actually refresh the secret, however if you first click Verify (which should fail), make a simple change to the Description (add an extra space, for example; anything to make it different than it was)
  9. Now click Save
  10. Now if you re-open the Edit Service Principal link, you should no longer see the warning about expired secrets, and if you go to the Certificates and secrets link on the blade, there should be exactly one secret and should be valid for 2 years from today’s date

Now, if you ever need to renew an Azure DevOps Service Connection’s expired secret, hopefully you can avoid wasting precious time by trying to figure out how to do it manually and just trick the system into doing it for you.

Purge a soft-deleted Azure API Management instance

   

Azure recently implemented a change to the API Management service whereby deleting the instance only puts it into a soft-deleted state rather than completely nuking it from orbit. This may be desirable for data recovery purposes but it means that if you run a terraform destroy on an environment with an APIM instance on it and then you try and rebuild that environment, it will fail due to the fact that the name you’re trying to use is being held onto by the previously removed instance. So since neither Azure CLI nor Az PowerShell natively support purging, I’m going to show you how to manually purge a soft-deleted Azure API Management instance.

NOTE: The below script uses the basic Az PowerShell tools but with a little elbow grease could be adapted to bash/zsh (provided you have a way of retrieving your Azure access token using OAuth).

$token = Get-AzAccessToken

$request = @{
    Method = 'DELETE'
    Uri    = "https://management.azure.com/subscriptions/{subscriptionGuid}/providers/Microsoft.ApiManagement/locations/{region}/deletedservices/{apimName}?api-version=2020-06-01-preview"
    Headers = @{
        Authorization = "Bearer $($token.Token)"
    }
}

Invoke-RestMethod @request

The only values you’ll need to supply are the subscriptionGuid, region, and apimName in the Uri.

Now the next time you’re stuck wondering why you can’t tear down and rebuild your environments with your IaC tool of choice, you’ll know how to purge a soft-deleted Azure API Management instance.

5 Ways to Secure Your Small Business Website

    

Your small business website is likely an essential part of your marketing strategy. It may also be your e-commerce sales channel or the platform you deliver your software on. In short, you need to keep your small business website safe. However, you likely can’t afford the same cybersecurity services as the big guys. Fortunately, there is a lot you can do yourself. This quick guide from nexxai.dev can help you figure out what you need to do.

Set Strong Login Credentials

The various login credentials you use for your website are one of your most important lines of defense. Make sure you are using long, strong passwords for any accounts. Additionally, at a minimum, all accounts with administrator access should be using either two-factor authentication or SSH keys. This may seem like a lot of trouble, but it is worth it.

Additionally, you should be very cautious about who has access to your website. If you need to give access to employees or freelancers, only give them the permissions they need. For example, if someone is just posting blogs, he or she doesn’t need administrator access.

Implement SSL

Secure socket layer or SSL is a technology used to encrypt data between computer browsers and website servers. It is a must-have technology for any small business website.

First, it will ensure that no one can snoop on the traffic between your visitors and your website. This includes if you are trying to log into your website back end from your own computer.

Second, many browsers are all but requiring HTTPS connections (achieved using SSL). It makes your website more secure, more professional-looking, and in compliance with the latest best practices. In short, you need to use this technology. According to the University of Michigan, around 80 percent of websites use HTTPS. If you aren’t, you are falling behind.

Back Up Your Website Often

You are hopefully already backing up your business data regularly. You should be doing the same with your website content. Anything that you have on your website should be backed up fairly regularly. If you post a lot of new content or capture customer data through your site, consider daily or even hourly backups. If not, you may be able to do weekly backups.

Get Help Configuring It

There are a lot of options when setting up a website, especially if you manage your own server or content management system. It is a good idea to get someone to help you set it up. This will help you to ensure that your website complies with all the latest security best practices. Even seemingly unrelated errors can cause significant vulnerabilities. Don’t risk your website or your business’s financial well-being. Consider hiring a freelancer. When you are considering an individual, look at his or her reviews from other customers. Also, make sure you have clear expectations about cost and delivery time.

Use Malware Protection

Finally, remember to use malware protection with your website hosting service. If you are renting or setting up a server on your own, you should install the appropriate anti-malware software – and keep it updated. Additionally, you will want a firewall (ideally a stand-alone network firewall). If you are using a shared hosting service, learn about your host’s security practices. Never use a host that doesn’t have a well-defined security plan.
