How It Works: The 5-Node Security Flow
How It Works: The 5-Node Security Flow This workflow efficiently performs a scheduled data breach scan. 1. Scheduled Check (Cron Node) This is the workflow's trigger. It schedules the workflow to run at a specific, regular interval. Function:** Continuously runs on a set schedule, for example, every Monday morning. Process:* The *Cron** node automatically initiates the workflow, ensuring routine data breach scans are performed without manual intervention. 2. List Emails to Check (Code Node) This node acts as your static database, defining which email addresses to monitor for breaches. Function:** Stores a list of email addresses from your team or customers in a single, easy-to-update array. Process:** It configures the list of emails that are then processed by the subsequent nodes. This makes it simple to add or remove addresses as needed. 3. Query HIBP API (HTTP Request Node) This node connects to the HaveIBeenPwned (HIBP) API to check for breaches. Function:** Queries the HIBP API for each email address on your list. Process:** It sends a request to the HIBP API. The API responds with a list of data breaches that the email was found in, if any. 4. Is Breached? (If Node) This is the core detection logic. It checks the API response to see if any breach data was returned. Function:** Compares the API's response to an empty array. Process:* If the API response is *not empty**, it indicates a breach has been found, and the workflow is routed to the notification node. If the response is empty, the workflow ends safely. 5. Send High-Priority Alert (Slack Node) / End Workflow (No-Op Node) These nodes represent the final action of the workflow. Function:** Responds to a detected breach. Process:* If a breach is found, the *Slack* node sends an urgent alert to your team's security channel, notifying them of the compromised email. If no breaches are found, the *No-Op** node ends the workflow without any notification. How to Set Up Implementing this essential cybersecurity monitor in your n8n instance is quick and straightforward. 1. Prepare Your Credentials & API Before building the workflow, ensure all necessary accounts are set up and their credentials are ready. HIBP API Key:* You need to get an *API key** from haveibeenpwned.com. This key is required to access the API. Slack Credential:* Set up a *Slack credential* in n8n and note the *Channel ID** of your security alert channel (e.g., #security-alerts). 2. Import the Workflow JSON Get the workflow structure into your n8n instance. Import:** In your n8n instance, navigate to the "Workflows" section. Click the "New" or "+" icon, then select "Import from JSON." Paste the provided JSON code into the import dialog and import the workflow. 3. Configure the Nodes Customize the imported workflow to fit your specific monitoring needs. Scheduled Check (Cron):** Set the schedule according to your preference (e.g., every Monday at 8:00 AM). List Emails to Check (Code):* Open this node and *edit the emailsToCheck array**. Enter the list of company email addresses you want to monitor. Query HIBP API (HTTP Request):** Open this node and in the "Headers" section, add the header hibp-api-key with the value of your HIBP API key. Send High-Priority Alert (Slack):* Select your *Slack credential* and replace YOUR_SECURITY_ALERT_CHANNEL_ID with your actual *Channel ID**. 4. Test and Activate Verify that your workflow is working correctly before setting it live. Manual Test:** Run the workflow manually. You can test with a known breached email address (you can find examples online) to ensure the alert is triggered. Verify:** Check your specified Slack channel to confirm that the alert is sent with the correct information. Activate:** Once you're confident in its function, activate the workflow. n8n will now automatically monitor your important accounts for data breaches on the schedule you set.
