-# Harden-Runner
+## Harden Github-hosted and self-hosted runners
 
-Corporate laptops and production servers typically have robust security monitoring in place to reduce risk and meet compliance requirements. However, CI/CD runners, which handle sensitive information like secrets for cloud environments and create production builds, often lack such security measures. This oversight has led to significant supply chain attacks, including the SolarWinds and Codecov breaches.
+Harden-Runner provides network egress filtering and runtime security for GitHub-hosted and self-hosted runners.
 
-Traditional security monitoring and EDR solutions are ineffective for CI/CD runners due to their ephemeral nature. These tools also lack the necessary context to correlate events with specific workflow runs in a CI/CD environment.
+Learn how Harden-Runner works through the video below, which shows how it detected a supply chain attack on a Google open-source project.
 
-StepSecurity Harden-Runner addresses this gap by providing security monitoring tailored for CI/CD runners, with support for Linux, Windows, and macOS runners. This approach brings CI/CD runners under the same level of security scrutiny as other critical systems, addressing a significant gap in the software supply chain.

+## How
 
----
-## Getting Started
+### GitHub-Hosted Runners
 
-This guide walks you through the steps to set up and use Harden-Runner in your CI/CD workflows. For more details, refer to the [official documentation](https://docs.stepsecurity.io/harden-runner).
+1. Add the `step-security/harden-runner` GitHub Action to your GitHub Actions workflow file as the first step in each job.
 
-### **Step 1: Add Harden-Runner to Your Workflow**
-
-To integrate Harden-Runner, follow these steps:
-
-- Open your GitHub Actions workflow file (e.g., `.github/workflows/<workflow-name>.yml`).
-- Add the following code as the first step in each job:
    ```yaml
    steps:
-     - name: Harden Runner
-       uses: step-security/harden-runner@f808768d1510423e83855289c910610ca9b43176 # v2.17.0
+     - uses: step-security/harden-runner@63c24ba6bd7ba022e95695ff85de572c04a18142 # v2.7.0
        with:
          egress-policy: audit
+   ```
 
-**Tip**: Automate this step by pasting your workflow into the [StepSecurity online tool](https://app.stepsecurity.io/secure-workflow)
-<details>
-<summary>Click to view the full Getting Started Guide</summary>
+2. In the workflow logs and the job markdown summary, you will see a link to security insights and recommendations.
 
-### **Step 2: Access Security Insights**
-
-Run your workflow. Once completed:
-- Review the **workflow logs** and the **job markdown summary**.
-- Look for a link to **security insights and recommendations**.

+    </p>
 
-- **Prevent Exfiltration:** Prevent the exfiltration of CI/CD secrets and source code.
-- **Detect Tampering:** Identify source code modifications during builds.
-- **Anomaly Detection:** Spot unusual dependencies and workflow behaviors.
-- **Simplify Permissions:** Determine the minimum required `GITHUB_TOKEN` permissions.
+4. In the `Recommended Policy` tab, you'll find a recommended block policy based on outbound calls aggregated from the current and past runs of the job. You can update your workflow file with this policy, or alternatively, use the [Policy Store](https://docs.stepsecurity.io/harden-runner/how-tos/block-egress-traffic#2-add-the-policy-using-the-policy-store) to apply the policy without modifying the workflow file. From now on, any outbound calls not in the allowed list will be blocked.

+
+## Support for Self-Hosted Runners and Private Repositories
+
+Hardening for self-hosted runners and GitHub-hosted runners used in private repositories is supported with a commercial license. Check out the [documentation](https://docs.stepsecurity.io/stepsecurity-platform/billing) for more details.
+
+- To use Harden-Runner in a `Private` repository, you must install the [StepSecurity Actions Security GitHub App](https://github.com/apps/stepsecurity-actions-security).
+- This is needed to access the GitHub Actions API and to authenticate users to access the insights URL for private repositories.
+- If you use Harden-Runner GitHub Action in a private repository, the generated insights URL is NOT public. Only those who have access to the repository can view it.
+
+Read this [case study on how Kapiche uses Harden-Runner](https://www.stepsecurity.io/case-studies/kapiche/) to improve software supply chain security in their private repositories.

+### Self-Hosted Actions Runner Controller (ARC) Runners
+
+> Explore demo workflows using self-hosted ARC Runner and ARC Harden-Runner [here](https://docs.stepsecurity.io/harden-runner/how-tos/enable-runtime-security-arc).
+
+Actions Runner Controller (ARC) is a Kubernetes operator that orchestrates self-hosted runners for GitHub Actions.
+
+- Instead of adding the Harden-Runner GitHub Action in each job, you'll need to install the ARC Harden-Runner daemonset on your Kubernetes cluster.
+- Upon installation, the ARC Harden-Runner daemonset monitors all jobs run on the cluster; you do NOT need to add the Harden-Runner GitHub Action to each job for `audit` mode. You do need to add the Harden-Runner GitHub Action to jobs where you want to enable `block` mode.
+- Please email support@stepsecurity.io for instructions on how to install the ARC-Harden-Runner daemonset on your Kubernetes cluster.
+
+### Self-Hosted VM Runners (e.g. on EC2)
+
+> Explore demo workflows using self-hosted VM Runners and Harden-Runner [here](https://docs.stepsecurity.io/harden-runner/how-tos/enable-runtime-security-vm).
+
+- Instead of adding the Harden-Runner GitHub Action in each job, you'll need to install the Harden-Runner agent on your runner image (e.g. AMI). This is typically done using packer or as a post-install step when using the https://github.com/philips-labs/terraform-aws-github-runner project to setup runners.
+- The Harden-Runner agent monitors all jobs run on the VM, both ephemeral and persistent runners are supported; you do NOT need to add the Harden-Runner GitHub Action to each job for `audit` mode. You do need to add the Harden-Runner GitHub Action to jobs where you want to enable `block` mode.
+- Please email support@stepsecurity.io for instructions on how to install the Harden-Runner agent on your self-hosted VM runners. This agent is different than the one used for GitHub-hosted runners.
+
+## Features at a glance
+
+For details, check out the documentation at https://docs.stepsecurity.io
+
+### 📶 View outbound network traffic
+
+> Applies to both GitHub-hosted and self-hosted runners
+
+Harden-Runner monitors all outbound traffic from each job at the DNS and network layers
+
+- After the workflow completes, each outbound call is correlated with each step of the job, and shown in the insights page
+- For self-hosted runners, no changes are needed to workflow files to monitor egress traffic
+- A filtering (block) egress policy is suggested in the insights page based on the current and past job runs
+
+### 🌐 View outbound HTTPS traffic
+
+> Applies to  GitHub-hosted and self-hosted VM runners
+
+Harden-Runner can monitor outbound HTTPS requests. This feature is supported with a commercial license.
+
+- HTTPS events are monitored using eBPF (no MITM proxy is used)
+- If a HTTP PUT/ POST/ PATCH call is made to `github.com` or `api.github.com` hosts to a HTTP Path with a different organization than where the workflow is running, the call is marked as anomalous
+- As of now, only HTTPS calls to `github.com` and `api.github.com` hosts are monitoried.
+
+<p align="left">
+  <img src="images/https-events.png" alt="Policy recommended by harden-runner" >
+</p>
+
+### ⚠️ Detect anomalous outbound network traffic
+
+> Applies to both GitHub-hosted and self-hosted runners
+
+Harden-Runner creates a baseline of outbound traffic for each job during the first few runs that it monitors
+
+- After the baseline is created, any new outbound destinations are marked as anomalous in the insights page
+- You can view the list of all anomalous outbound network traffic in the `Runtime detections` page on the dashboard
 
 
----
+### 🚦 Filter outbound network traffic to allowed endpoints
 
-## Features
+> Applies to both GitHub-hosted and self-hosted runners
 
-Harden-Runner offers a comprehensive suite of features to enhance the security of your CI/CD workflows, available in two tiers: **Community** (Free) and **Enterprise** (Paid).
+Once allowed endpoints are set in the policy in the workflow file, or in the [Policy Store](https://docs.stepsecurity.io/harden-runner/how-tos/block-egress-traffic#2-add-the-policy-using-the-policy-store)
 
-### Community (Free)
+- Harden-Runner blocks egress traffic at the DNS (Layer 7) and network layers (Layers 3 and 4)
+- It blocks DNS exfiltration, where attacker tries to send data out using DNS resolution
+- Wildcard domains are supported, e.g. you can add `*.data.mcr.microsoft.com:443` to the allowed list, and egress traffic will be allowed to `eastus.data.mcr.microsoft.com:443` and `westus.data.mcr.microsoft.com:443`
 
-- **CI/CD-Aware Event Correlation:** Each outbound network connection, file operation, and process execution is mapped to the exact step, job, and workflow where it occurs.
-- **Automated Baseline Creation:** Harden-Runner builds a baseline for each job based on past outbound network connections.
-- **Anomaly Detection:** Once the baseline is created, any future outbound calls not in the baseline trigger a detection.
-- **Block Network Egress Traffic with Domain Allowlist:** Optionally use the automatically created baseline to control outbound network traffic by specifying allowed domains, preventing unauthorized data exfiltration.
-- **Detect Modification of Source Code:** Monitor and alert on unauthorized changes to your source code during the CI/CD pipeline.

+Harden-Runner monitors file writes and can detect if a file is overwritten.
 
----
+- Source code overwrite is not expected in a release build
+- All source code files are monitored, which means even changes to IaC files (Kubernetes manifest, Terraform) are detected
+- You can enable notifications to get one-time alert when source code is overwritten
+- For self-hosted runners, no changes are needed to workflow files for file monitoring
 
-## Environment Compatibility Matrix
+<p align="left">
+  <img src="images/file-events.png" alt="Policy recommended by harden-runner" >
+</p>
 
-Harden-Runner is designed to work seamlessly across a variety of runner environments, providing consistent security insights and protections regardless of where your workflows execute. For self-hosted runners, audit mode is deployed directly to the runner infrastructure without requiring any changes to your existing workflows. For more details, refer to the [official documentation](https://docs.stepsecurity.io/harden-runner).
+### 🚫 Run your job without sudo access
 
-| Environment Type | Compatibility | Audit Mode Deployment | Workflow Changes for Audit/Block Mode |
-|------------------|---------------|--------------------------|-------------------|
-| GitHub-hosted runners (Linux) | ✅ Full support | Add Harden-Runner Action to workflow | Yes |
-| GitHub-hosted runners (Windows, macOS) | ✅ Audit mode only | Add Harden-Runner Action to workflow | Yes |
-| Self-hosted VM runners | ✅ Full support | Include agent in runner image | No |
-| Self-hosted bare-metal runners | ✅ Full support | Install agent as a service | No |
-| Actions Runner Controller (ARC) | ✅ Full support | Deploy as DaemonSet | No |
-| RunsOn Runners | ✅ Full support | Pre-integrated | No |
+> Applies to GitHub-hosted runners
 
-## How It Works
+GitHub-hosted runner uses passwordless sudo for running jobs.
 
-Want to know the technical details? Dive into the architecture of Harden-Runner and its integrations for GitHub-hosted and self-hosted runners in our [How Harden-Runner Works Documentation](docs/how-it-works.md).
+- This means compromised build tools or dependencies can install attack tools
+- If your job does not need sudo access, you see a policy
+  recommendation to disable sudo in the insights page
+- When you set `disable-sudo` to `true`, the job steps run without sudo access to the GitHub-hosted Ubuntu VM
 
----
+### 🔔 Get security alerts
 
-## Limitations
+> Applies to both GitHub-hosted and self-hosted runners
 
-While Harden-Runner offers powerful features, there are certain limitations. See the complete list in [Known Limitations](docs/limitations.md).
+Install the [StepSecurity Actions Security GitHub App](https://github.com/apps/stepsecurity-actions-security) to get security alerts.
 
----
+- Email and Slack notifications are supported
+- Notifications are sent when outbound traffic is blocked or source code is overwritten
+- Notifications are not repeated for the same alert for a given workflow

+- If you have questions or ideas, please use [discussions](https://github.com/step-security/harden-runner/discussions).
+- For support for self-hosted runners and private repositories, email support@stepsecurity.io.
+- If you use a different CI/CD Provider (e.g. Jenkins, Gitlab CI, etc), and would like to use Harden Runner in your environment, please email interest@stepsecurity.io
 
-For enterprise support, email support@stepsecurity.io. Interested in using Harden-Runner in other CI/CD platforms? Reach out to interest@stepsecurity.io.
+## How does it work?
 
----
+### GitHub-Hosted Runners
 
-## License
+For GitHub-hosted runners, Harden-Runner GitHub Action downloads and installs the StepSecurity Agent.
 
-Harden-Runner is open source. See the [LICENSE](LICENSE) file for details.
+- The code to monitor file, process, and network activity is in the Agent.
+- The agent is written in Go and is open source at https://github.com/step-security/agent
+- The agent's build is reproducible. You can view the steps to reproduce the build [here](http://app.stepsecurity.io/github/step-security/agent/releases/latest)
+
+### Self-Hosted Actions Runner Controller (ARC) Runners
+
+- ARC Harden Runner daemonset uses eBPF
+- You can find more details in this blog post: https://www.stepsecurity.io/blog/introducing-harden-runner-for-kubernetes-based-self-hosted-actions-runners
+- ARC Harden Runner is NOT open source.
+
+### Self-Hosted VM Runners (e.g. on EC2)
+
+- For self-hosted VMs, you add the Harden-Runner agent into your runner image (e.g. AMI).
+- Agent for self-hosted VMs is NOT open source.
+
+## Limitations
+
+### GitHub-Hosted Runners
+
+1. Only Ubuntu VM is supported. Windows and MacOS GitHub-hosted runners are not supported. There is a discussion about that [here](https://github.com/step-security/harden-runner/discussions/121).
+2. Harden-Runner is not supported when [job is run in a container](https://docs.github.com/en/actions/using-jobs/running-jobs-in-a-container) as it needs sudo access on the Ubuntu VM to run. It can be used to monitor jobs that use containers to run steps. The limitation is if the entire job is run in a container. That is not common for GitHub Actions workflows, as most of them run directly on `ubuntu-latest`. Note: This is not a limitation for Self-Hosted runners.
+
+### Self-Hosted Actions Runner Controller (ARC) Runners
+
+1. Since ARC Harden Runner uses eBPF, only Linux jobs are supported. Windows and MacOS jobs are not supported.
+
+### Self-Hosted VM Runners (e.g. on EC2)
+
+1. Only Ubuntu VM is supported. Windows and MacOS jobs are not supported.
