Dependency Scanning

Modern dependency and container scanning leverages AI/ML capabilities to detect vulnerabilities, analyze dependencies, and provide intelligent remediation suggestions. This guide covers current best practices and tools for securing your container ecosystem.

Why Dependency and Container Scanning

In cloud-native environments, container security is critical due to:

• Complex dependency chains

• Supply chain attacks

• Zero-day vulnerabilities

• Compliance requirements

• Runtime security risks

• AI/ML model dependencies

Modern Scanning Approaches

1. AI-Enhanced Scanning

# filepath: /scripts/security/ai_scanner.py
from anthropic import Anthropic
from google.cloud import aiplatform
import json

class AISecurityScanner:
    def __init__(self):
        self.claude = Anthropic()
        self.gemini = aiplatform.init()
        
    async def analyze_dependencies(self, sbom_data: dict):
        prompt = f"""
        Analyze this software bill of materials (SBOM):
        {json.dumps(sbom_data, indent=2)}

        Identify:
        1. Critical vulnerabilities
        2. Supply chain risks
        3. Dependency conflicts
        4. License compliance issues
        5. Security best practices
        """

        # Get multiple AI perspectives
        claude_analysis = await self.claude.messages.create(
            model="claude-3-opus-20240229",
            temperature=0,
            messages=[{"role": "user", "content": prompt}]
        )

        gemini_analysis = await self.gemini.generate_content(prompt)

        return self._combine_analyses(claude_analysis, gemini_analysis)

2. NixOS Container Security

# filepath: /etc/nixos/container-security.nix
{ config, pkgs, ... }:

{
  virtualisation.docker = {
    enable = true;
    enableOnBoot = true;
    daemon.settings = {
      features = {
        buildkit = true;
      };
      securityOpts = [
        "no-new-privileges"
        "seccomp=unconfined"
      ];
    };
  };

  environment.systemPackages = with pkgs; [
    trivy
    grype
    syft
    docker-compose
    crane
    cosign
  ];

  security.lockKernelModules = true;
  security.protectKernelImage = true;
}

3. WSL2 Security Integration

# filepath: /scripts/setup-wsl-security.ps1
# Configure WSL for secure container scanning
$wslConfig = @"
[wsl2]
memory=8GB
processors=4
kernelCommandLine = vsyscall=emulate
nestedVirtualization=true

[experimental]
networkingMode=mirrored
dnsTunneling=true
firewall=true
"@

Set-Content -Path "$env:USERPROFILE\.wslconfig" -Value $wslConfig

# Install security tools in WSL
wsl -d Ubuntu-22.04 bash -c '
# Add security repositories
curl -fsSL https://pkg.snyk.io/key | sudo gpg --dearmor -o /usr/share/keyrings/snyk-archive-keyring.gpg

# Install tools
sudo apt update && sudo apt install -y \
  trivy \
  grype \
  syft \
  snyk \
  docker.io \
  python3-pip

# Install AI tools
pip3 install anthropic google-cloud-aiplatform openai'
