+# Harden-Runner
+
+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.
+
+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.
+
+StepSecurity Harden-Runner addresses this gap by providing security monitoring tailored for CI/CD 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.

+## Getting Started
 
-## Why
+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).
 
-Compromised dependencies and build tools typically make outbound calls to exfiltrate credentials, or may tamper source code, dependencies, or artifacts during the build.
+### **Step 1: Add Harden-Runner to Your Workflow**
 
-Harden-Runner GitHub Actions installs a daemon that monitors process, file, and network activity to:

+## Features
 
-<p align="left">
-  <img src="images/main-screenshot1.png" alt="Policy recommended by harden-runner">
-</p>
+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).
 
-### Restrict egress traffic to allowed endpoints
+### Community (Free)
 
-Once allowed endpoints are set in the workflow file,
+- **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 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
-- Blocks outbound traffic using IP tables
+### Enterprise (Paid)
 
-<p align="left">
-  <img src="images/block-outbound-call.png" alt="Policy recommended by harden-runner" >
-</p>
+Includes all features in the **Community** tier, plus:
 
-### Detect tampering of source code during build
+- **Support for Private Repositories:** Extend Harden-Runner's security capabilities to your private GitHub repositories.
+- **Support for Self-Hosted Runners:** Apply security controls and monitoring to self-hosted GitHub Actions runners.
+- **GitHub Checks Integration:** Enable GitHub Checks for Harden-Runner—if the baseline remains unchanged, the check passes; if it changes, the check fails, showing new outbound connections.
+- **View Outbound GitHub API calls at the Job Level:** Monitor HTTPS requests to GitHub APIs
+- **Determine Minimum GITHUB_TOKEN Permissions:** Monitor outbound HTTPS requests to GitHub APIs to recommend the least-privilege permissions needed for your workflows, enhancing security by reducing unnecessary access.
+- **View the Name and Path of Every File Written During the Build Process:** Gain visibility into every file written to the build environment, including the ability to correlate file writes with processes, ensuring complete transparency.
+- **View Process Names and Arguments:** Monitor every process executed during the build process, along with its arguments, and navigate the process tree to detect suspicious activities.

-1. Harden-Runner GitHub Action only works for GitHub-hosted runners. Self-hosted runners are not supported.
-2. 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).
-3. 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`.
+While Harden-Runner offers powerful features, there are certain limitations based on the environment, such as OS support. See the complete list in [Known Limitations](docs/limitations.md).

-## How does it work?
-
-Harden-Runner GitHub Action downloads and installs the StepSecurity Agent.
-
-- 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)
+Harden-Runner is open source. See the [LICENSE](LICENSE) file for details.

+## How Harden-Runner Works?
+
+### GitHub-Hosted Runners
+
+For GitHub-hosted runners, Harden-Runner GitHub Action downloads and installs the StepSecurity Agent.
+
+- The code to monitor file, process, and network activity is in the Agent.
+- The community tier agent is open-source and can be found [here](https://github.com/step-security/agent). The enterprise tier agent is closed-source. Both agents are written in Go.
+- 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).
+- You can find more details in this [blog post](https://www.stepsecurity.io/blog/ci-cd-security-for-self-hosted-vm-runners)
+- Agent for self-hosted VMs is NOT open source.

+### GitHub-Hosted Runners

+* 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) with built-in labels such as `ubuntu-latest`, as it needs sudo access on the Ubuntu VM to run. The limitation is if the entire job is run in a container. However, such jobs can be monitored when using custom VM images with GitHub-hosted runners. This is also not a limitation for Self-Hosted runners.
+
+### Self-Hosted Actions Runner Controller (ARC) Runners
+
+* Since ARC Harden Runner uses eBPF, only Linux jobs are supported. Windows and MacOS jobs are not supported.
+
+### Self-Hosted VM (e.g. on EC2) and Bare-metal Runners 
+
+* Only Linux jobs are supported. Windows and MacOS jobs are not supported.
