Security Audit

Hey there! Ever wondered if your n8n instance is as secure as Fort Knox? Well, buckle up because today we’re diving deep into the world of security audits for n8n. I’m telling you, running a security audit on your n8n instance is not just a good idea; it’s absolutely essential if you want to keep those pesky security issues at bay. Whether you’re a seasoned pro or just starting out, understanding how to detect and address these vulnerabilities will save you headaches down the line. So, let’s get into it and see how you can run an audit using the CLI, the public API, or even the n8n nodes themselves. Ready? Let’s go!

Why You Should Run a Security Audit on Your n8n Instance

Listen, if you’re not regularly checking the security of your n8n instance, you’re playing with fire. Here’s why: A security audit helps you spot those common security issues before they become a nightmare. We’re talking about everything from unused credentials to outdated instances that hackers love to exploit. It’s like having a security guard for your digital assets, and trust me, you don’t want to skimp on this.

Wondering how this works? Well, the audit generates five risk reports: Credentials, Database, File System, Nodes, and Instance. Each report gives you a detailed look at where your system might be vulnerable. And the best part? You can run these audits using different methods, so you’re not stuck with just one option.

How to Run a Security Audit Using the CLI

If you’re a command-line kind of person, you’re in luck. Running an n8n audit via the CLI is as easy as pie. Just type in n8n audit and watch the magic happen. This method is perfect for those of you who like to keep things simple and straightforward. It’ll give you a comprehensive overview of your system’s security in no time.

Running a Security Audit via the Public API

Now, if you’re more of an API enthusiast, you can make a POST call to the /audit endpoint. Just remember, you’ll need to authenticate as the instance owner to get the ball rolling. This method is great for those of you who want to automate the process or integrate it into your existing workflows. It’s all about making your life easier, right?

Using n8n Nodes for Your Security Audit

And for those of you who love the n8n interface, you can add the [audit node] to your workflow. Just select Resource > Audit and Operation > Generate, and you’re good to go. This method is perfect for those of you who want to keep everything within the n8n ecosystem. It’s user-friendly and gives you all the insights you need to keep your system safe.

Understanding the Audit Reports

Let’s break down what these audit reports are all about:

• Credentials Report: This one shows you credentials that are not being used in your workflows. You’ll see categories like “Credentials not used in a workflow”, “Credentials not used in an active workflow”, and “Credentials not used in a recently active workflow”. It’s like cleaning out your digital closet – get rid of what you don’t need.
• Database Report: Here, you’ll find details on expressions and query parameters used in SQL nodes. Look out for “Expressions used in Execute Query fields in SQL nodes”, “Expressions used in Query Parameters fields in SQL nodes”, and “Unused Query Parameters fields in SQL nodes”. It’s all about keeping your database clean and secure.
• File System Report: This report lists nodes that interact with the file system. It’s crucial to know which parts of your system are touching the file system to prevent unauthorized access.
• Nodes Report: This one is all about the nodes themselves. You’ll see categories like “Official risky nodes”, “Community nodes”, and “Custom nodes”. And let me tell you, those official risky nodes are something to watch out for. They’re n8n built-in nodes that can fetch and run any code on the host system, exposing your instance to potential exploits. You can view the list of these nodes under OFFICIAL_RISKY_NODE_TYPES.
• Instance Report: Finally, this report shows you if there are unprotected webhooks in your instance, missing security settings, or if your instance is outdated. It’s like a health check for your entire n8n setup.

Final Thoughts on n8n Security Audits

So, there you have it! Running a security audit on your n8n instance is not just a good idea; it’s a must-do if you want to keep your system safe and sound. Whether you choose the CLI, the public API, or the n8n nodes, you’ve got plenty of options to make it happen. Remember, the audit reports give you a detailed look at where you might be vulnerable, so take action and keep those security issues at bay.
