Tool to detect Privilege Escalation and Data Tampering risks in Docker environments

IntegrityGuard: Docker Security Assessment Tool

IntegrityGuard is a security tool designed to detect Privilege Escalation and Data Tampering risks in multi-user Docker environments.

It implements the methodology described in the research "Segurança em Docker Multiusuário: Avaliação de Riscos", focusing on the dangers of exposing the Docker socket (/var/run/docker.sock) to non-privileged users.

🚀 Key Features

• Vulnerability Diagnosis: Checks if the current user is improperly added to the docker group or has write access to the socket.
• Safe Proof-of-Concept (PoC): Simulates a "Host Breakout" attack by attempting to mount the host filesystem and write a harmless test file, proving the viability of Data Tampering without damaging the system.
• IEVI Score Calculation: Quantifies the risk using the Integrity Violation Exposure Index (IEVI), a metric derived from the DREAD threat modeling framework.
• SonarQube-like Reporting: Generates visual HTML dashboards or JSON output for CI/CD integration.

📦 Installation

Install the tool directly from PyPI:

pip install integrityguard-cli

🛠️ Usage

Once installed, the integrity-guard command is available globally.

1. Standard Analysis (Console Output)

Runs the diagnosis and prints the findings and IEVI score to the terminal.

integrity-guard

2. Generate HTML Dashboard

Creates a visual report (integrity_scan_report.html) containing the risk score, DREAD breakdown, and detailed findings.

integrity-guard --html

3. JSON Output (DevOps/CI)

Outputs the raw data in JSON format for parsing by other tools.

integrity-guard --json

📊 How It Works (Methodology)

The tool operates in three phases:

1. Diagnosis: It inspects user permissions and group memberships. Adding a user to the docker group is equivalent to granting them root access.
2. Simulation: It attempts to spin up a container with -v /:/mnt/host to verify if the host filesystem is writable.
3. Scoring: It calculates the IEVI (Integrity Violation Exposure Index).
   • Score > 40: Indicates a Critical risk where an attacker can modify /etc/passwd or other sensitive files.
   • Score < 40: Indicates a Tolerable risk (e.g., Rootless Docker).

🛡️ Mitigation

If IntegrityGuard reports a critical vulnerability, the recommended mitigation is to migrate to Docker Rootless mode or remove the user from the docker group.
