Reticulum: Advanced Cloud Infrastructure Security Scanner

The DevSecOps Security Challenge

Your deployment pipeline is probably leaking security issues right now. Every commit, every Helm chart update, every infrastructure change introduces potential vulnerabilities that slip through traditional security reviews. As a DevSecOps engineer, you need visibility into your entire cloud security posture - not just at deployment, but throughout your entire development lifecycle.

Reticulum addresses this challenge head-on. It’s not just another security scanner – it’s a comprehensive DevSecOps security intelligence platform designed to integrate seamlessly into your CI/CD pipelines and provide continuous security validation for your cloud-native infrastructure.

Solving Modern DevSecOps Security Problems

Your infrastructure deployment workflow probably looks something like this: developers push Helm charts, CI/CD pipelines deploy to Kubernetes, and security reviews happen… well, hopefully somewhere in between. But here’s the reality - by the time security issues are discovered, they’re already in production.

Reticulum transforms this reactive approach into a proactive DevSecOps practice by providing automated security analysis that:

• Integrates directly into CI/CD pipelines for shift-left security validation
• Automates security policy enforcement across all deployment environments
• Provides compliance validation against industry frameworks (CIS, NIST, PCI-DSS)
• Enables Infrastructure as Code security with template analysis and drift detection
• Supports policy as code workflows for automated governance

This represents a fundamental shift from traditional security approaches – instead of bolting security onto your DevOps process, Reticulum makes security an integral part of your development velocity.

Installation and Setup

Reticulum is designed for seamless integration into your existing DevSecOps workflows. Here’s how to get started:

Installation (Recommended)

Install Reticulum directly from PyPI using pip:

pip install reticulum

This will install the latest stable version along with all required dependencies.

• Poetry (for source installation)

DevSecOps Quick Start

Start scanning your infrastructure immediately:

# Basic scan of a repository
reticulum /path/to/your/repository

# Scan with JSON output (recommended for automation)
reticulum /path/to/your/repository --json

# Scan with human-readable console output
reticulum /path/to/your/repository --console

# Detailed path analysis
reticulum /path/to/your/repository --paths

CI/CD Pipeline Integration

Add Reticulum to your pipeline for automated security scanning:

# GitHub Actions example
name: Security Scan
on: [push, pull_request]

jobs:
  security:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

      - name: Set up Python
        uses: actions/setup-python@v4
        with:
          python-version: '3.9'

      - name: Install Reticulum
        run: pip install reticulum

      - name: Run Security Scan
        run: |
          reticulum . --json > security-report.json

      - name: Upload Security Report
        uses: actions/upload-artifact@v3
        with:
          name: security-report
          path: security-report.json

What Gets Scanned

Reticulum automatically discovers and analyzes:

• Helm Charts in your repository
• Kubernetes manifests (YAML files)
• Dockerfiles associated with your services
• Service dependencies and relationships
• Network topology and exposure patterns

The Architecture

Let me show you what we’re working with here. This isn’t your typical “scan and pray” tool. Reticulum is built with a modular approach, designed to analyze your infrastructure systematically and provide clear insights into what needs attention.

The 18 Exposure Patterns (And 12 Risk Patterns)

This is where Reticulum shows its depth. It doesn’t just look for obvious exposures like “this service is exposed to the internet.” It has 18 different exposure patterns that it systematically searches for across your infrastructure.

Exposure Level	Description	Examples
HIGH	Immediate attention required	LoadBalancer Services → Direct internet access NodePort Services → Through the node's firewall Ingress Controllers → Gateway to external traffic Host Network Access → Sharing the host's network stack Direct Port Binding → Bypassing security layers
MEDIUM	Monitor closely	Standard Ingress → Through your gateway Service Mesh → Through your mesh infrastructure Linked Services → Connected to exposed services
LOW	Generally safe	Internal Services → Only accessible from within Database Services → Internal data storage Worker Services → Background processing services

It also identifies 12 risk patterns that security professionals need to be aware of:

Risk Category	Description
Privileged Containers	Running with elevated privileges
Root User Execution	Containers running as root user
Host Namespace Access	Access to host namespaces
Dangerous Linux Capabilities	SYS_ADMIN, SYS_PTRACE capabilities
Privilege Escalation	Ability to escalate privileges
Resource Management	Missing resource limits, latest image tags

Multi-Environment Support

Here’s where Reticulum shows its flexibility. It doesn’t just scan your base configuration – it adapts to analyze different environments:

Environment	Base Values	Environment-Specific	Smart Merge
Development	✓	✓	✓
Staging	✓	✓	✓
Production	✓	✓	✓

It’s like having a security expert who can analyze each environment and spot the differences that could lead to security issues.

Performance

Let me tell you about the performance. This tool is fast and efficient:

• Scan Time: Less than 30 seconds for complex repositories
• Memory Usage: Under 512MB peak
• Scalability: Handles 100+ charts without issues
• Concurrent Processing: Multiple workers scanning in parallel

Metric	Value	Description
Scan Speed	< 30 sec	Fast processing for complex repositories
Memory Usage	< 512MB	Lightweight resource consumption
Scalability	100+ charts	Handles large-scale deployments

Output Formats

Now, let’s talk about the output. Reticulum provides multiple ways to consume its findings, making it easy to integrate with your existing tools and workflows:

Color-Coded Console Output

The console output provides clear visual indicators:

• Red: High exposure (immediate action required)
• Yellow: Medium exposure (monitor closely)
• Green: Low exposure (generally safe)

Mermaid Diagrams

It generates Mermaid diagrams that show your network topology, color-coded by exposure levels. It’s like having a visual map of your infrastructure that helps you understand the security landscape at a glance.

JSON Integration

Structured data that you can feed into your SIEM, your compliance tools, your reporting systems, or whatever security toolchain you’re running.

Practical Examples

Let’s see Reticulum in action with real examples:

Basic Repository Scan

# Scan a typical microservices repository
reticulum /path/to/microservices-repo

This will analyze all Helm charts in the repository and provide a summary of findings.

Detailed Analysis with JSON Output

# Generate structured output for automation
reticulum /path/to/microservices-repo --json > security-report.json

Example JSON Output:

{
  "scan_summary": {
    "total_containers": 15,
    "high_exposure": 3,
    "medium_exposure": 5,
    "low_exposure": 7,
    "scan_time": "23.4s"
  },
  "containers": [
    {
      "name": "frontend-web",
      "exposure_level": "HIGH",
      "gateway_type": "ingress",
      "host": "example.com",
      "chart_path": "charts/frontend-web",
      "dockerfile_path": "frontend/Dockerfile"
    }
  ],
  "network_topology": {
    "exposed_containers": ["frontend-web", "api-gateway"],
    "linked_containers": ["backend-service", "worker-service"],
    "internal_containers": ["database", "cache", "monitoring"]
  }
}

echo "🔍 Running Reticulum security scan..."
reticulum . --json > security-report.json

# Check for high-exposure containers
HIGH_EXPOSURE=$(jq '.scan_summary.high_exposure' security-report.json)

if [ "$HIGH_EXPOSURE" -gt 5 ]; then
    echo "❌ Security check failed: $HIGH_EXPOSURE high-exposure containers found"
    echo "Review the security report and reduce exposure levels"
    exit 1
else
    echo "✅ Security check passed: $HIGH_EXPOSURE high-exposure containers"
fi

# Compare environments
reticulum ./charts --console > dev-scan.txt
reticulum ./charts --console > staging-scan.txt
reticulum ./charts --console > prod-scan.txt

# Analyze differences between environments
diff dev-scan.txt prod-scan.txt

Benefit: Identify configuration drift and environment-specific security risks.

4. Security Training and Education

Scenario: Help developers understand security implications of their configurations.

# Generate educational report for development team
reticulum ./microservices --console --paths > training-report.txt

# Highlight specific security patterns
grep -A 5 -B 5 "HIGH EXPOSURE" training-report.txt

Benefit: Developers learn security best practices through real examples.

Technical Implementation

Dockerfile Analysis

Reticulum uses a systematic approach to find and analyze Dockerfiles:

1. Chart Directory: Look right where the chart lives
2. Subdirectories: Check the obvious subdirectories
3. Repository Root: Look for Dockerfiles with the same name as the chart
4. Single-App Repos: Handle the simple cases
5. Common Locations: Check the standard places (src/, apps/, services/)

Path Consolidation

It doesn’t just find paths – it understands them. It builds master paths, analyzes hierarchies, and gives you a complete picture of how your source code flows through your infrastructure.

Dependency Analysis

It reconstructs the relationships between your containers, understands your service mesh, and can tell you exactly how one service depends on another.
