EDRmetry is an advanced tool designed to evaluate and enhance your Linux security system posture, with a specific focus on assessing EDR/XDR/SIEM detection capabilities. It serves as a comprehensive, vendor-agnostic playbook for offensive Linux testing and operations, providing cybersecurity professionals with the means to thoroughly test and improve their Linux-based security infrastructure.

EDRmetry addresses several critical challenges in the cybersecurity landscape:

1. The increasing complexity of Linux-based attacks and the need for specialized testing tools

2. The difficulty in evaluating the effectiveness of EDR/XDR solutions in Linux environments

3. The knowledge gap in understanding and mitigating Linux-specific security threats

4. The need for practical, hands-on tools to improve SOC capabilities and incident response in Linux ecosystems

EDRmetry stands out in several ways:

1. Linux Focus: Unlike many tools that primarily target Windows environments, EDRmetry is specifically designed for Linux systems.

2. Comprehensive Knowledge Base: It provides a centralized repository of Linux offensive techniques with ready-to-use code snippets.

3. Practical Approach: EDRmetry emphasizes real-world attack scenarios and techniques observed in actual APT activities.

4. Modularity: The tool allows for creating full attack chains, useful in threat emulation and forensics exercises.

5. Educational Component: It includes a built-in learning portal about Linux EDR features and market-leading solutions.

EDRmetry enables a wide range of security tests, including but not limited to:

1. Full kill chain testing: From initial access to command and control (C2) and data exfiltration

2. EDR/XDR efficacy evaluation: Testing detection capabilities against various attack techniques

3. SIEM integration testing: Assessing how security events are captured and processed

4. Custom attack chain creation: Building and executing tailored attack scenarios

5. Network-oriented security checks: Profiling network traffic and testing NIDS/NIPS/Corporate Proxy and NG-Firewalls

EDRmetry is designed to be vendor-agnostic, allowing you to:

1. Test multiple EDR/XDR solutions using the same set of techniques

2. Compare detection capabilities across different products

3. Identify strengths and weaknesses in each solution's approach to Linux security

4. Fine-tune and optimize your chosen EDR/XDR solution based on test results

Yes, EDRmetry is designed with flexibility in mind:

1. It can augment tools like Mitre CALDERA or Atomic Red Team with Linux-specific techniques
