  1. Access Azure Portal: Sign into the Azure portal with your Azure account credentials.
  2. Create or Select Logic App: If you haven’t already, create a Logic app by navigating to “Create a resource” and searching for “Logic App” or selecting an existing one.
  3. Design Your Workflow: In the Logic App designer, choose a trigger that will initiate the workflow. You can use a scheduled trigger (e.g., Recurrence) to check certificates periodically for certificate monitoring. After the trigger, add a condition to check if a certificate is close to expiration. Use the “Azure Key Vault” connector to retrieve certificate details.
  4. Set Up the Key Vault Connector: Configure the Azure Key Vault connector to connect to your Key Vault. You’ll need to provide authentication and permissions to access the Key Vault.
  5. Retrieve Certificate Information: Use the Key Vault connector to retrieve certificate information, including its expiration date.
  6. Add a Condition: Add a condition to check if the certificate’s expiration date is within the threshold you want to monitor (e.g., 30 days before expiration).
  7. Define Actions: If the condition is met, define the actions you want to take. These include sending email notifications, triggering an alert, or taking specific remediation steps.
  8. Save and Enable the Logic App: Save your Logic App and enable it. It will now run based on the schedule you defined in the trigger. You can test the Logic App by manually triggering it to ensure it correctly monitors certificate expiration.
  9. Monitoring: Your Logic App will now automatically run based on the schedule you defined, checking the certificates in your Key Vault. If a certificate is close to expiration, it will trigger the defined actions.
