Comprehensive Tutorial: Aqua Security in DevSecOps

by

Introduction & Overview

What is Aqua Security?

Aqua Security is a leading Cloud Native Application Protection Platform (CNAPP) designed to secure containerized, serverless, and cloud-native applications across their entire lifecycle—from development to production. It integrates security practices into DevOps workflows, aligning with the DevSecOps philosophy of embedding security early and continuously in the software development lifecycle (SDLC). Aqua provides tools for vulnerability scanning, runtime protection, compliance enforcement, and more, tailored for modern, dynamic cloud environments.

History or Background

Founded in 2015 by Dror Davidoff and Amir Jerbi, Aqua Security emerged to address the security challenges of containerized applications and microservices. Headquartered in Boston, MA, and Ramat Gan, Israel, Aqua has grown to protect over 500 enterprises worldwide. Its flagship offering, the Aqua Platform, combines agent-based and agentless security technologies to provide comprehensive protection. Key milestones include the development of Trivy, an open-source vulnerability scanner, and achieving significant adoption in industries like finance, healthcare, and government.

Why is it Relevant in DevSecOps?

DevSecOps emphasizes integrating security into every phase of the SDLC to reduce vulnerabilities and ensure compliance without slowing development. Aqua Security is pivotal in this paradigm because it:

  • Enables Shift-Left Security: Identifies vulnerabilities early in development, reducing remediation costs.
  • Supports CI/CD Integration: Seamlessly integrates with tools like Jenkins, GitLab, and GitHub Actions for automated security checks.
  • Addresses Cloud-Native Challenges: Secures containers, Kubernetes, and serverless architectures, which are prevalent in modern applications.
  • Ensures Compliance: Aligns with standards like PCI-DSS, HIPAA, and GDPR, critical for regulated industries.

Aqua’s relevance stems from its ability to bridge the gap between development speed and robust security, making it a cornerstone for organizations adopting DevSecOps.

How It Fits into the DevSecOps Lifecycle

Aqua Security aligns with the DevSecOps lifecycle by embedding security across:

  • Plan: Define security policies and compliance requirements using the Aqua Console.
  • Code: Scan source code and Infrastructure as Code (IaC) with Trivy for vulnerabilities and misconfigurations.
  • Build: Integrate Trivy into CI/CD pipelines to scan container images before deployment.
  • Test: Perform dynamic threat analysis and compliance checks during testing phases.
  • Deploy: Use Aqua Enforcer to prevent unapproved images from being deployed.
  • Operate: Monitor runtime behavior with Aqua Enforcer and Tracee (an eBPF-based runtime security tool).
  • Monitor: Provide continuous observability and incident response capabilities.

This lifecycle integration ensures security is a shared responsibility across development, security, and operations teams.

Architecture & How It Works

Components and Internal Workflow

Aqua Security’s architecture comprises:

  • Aqua Server: Central hub for policy management, data aggregation, and orchestration.
  • Aqua Console: Web-based UI for configuring policies and viewing security insights.
  • Aqua Enforcer: Lightweight agents on container hosts for runtime monitoring and policy enforcement.
  • Trivy Scanner: Open-source tool for scanning container images, IaC, and repositories.
  • Tracee: eBPF-based tool for runtime security and behavioral analysis.
  • Gateways: Facilitate communication between components in distributed environments.

Workflow:

  1. Code Scanning: Trivy scans source code, IaC, and container images in repositories or CI/CD pipelines for vulnerabilities and misconfigurations.
  2. Policy Enforcement: Aqua Server applies custom policies to block non-compliant images or configurations.
  3. Runtime Protection: Aqua Enforcers monitor running containers, detecting and mitigating threats in real-time.
  4. Incident Response: Aqua Console aggregates alerts, enabling teams to investigate and remediate issues.

Architecture Diagram Description

The Aqua Security architecture can be visualized as a layered system:

  • Top Layer (Aqua Console): A web interface for administrators to manage policies and view dashboards.
  • Middle Layer (Aqua Server): Connects to the console, orchestrators (e.g., Kubernetes), and CI/CD tools, orchestrating scans and policies.
  • Bottom Layer (Aqua Enforcers): Deployed on container hosts, interacting with the runtime environment.
  • External Integrations: Connects to cloud providers (AWS, Azure, GCP), CI/CD tools (Jenkins, GitLab), and secret vaults.

Data flows from Enforcers and Trivy to the Server, which processes and sends insights to the Console. Integrations ensure seamless communication with external tools.

Integration Points with CI/CD or Cloud Tools

Aqua integrates with:

  • CI/CD Tools: Jenkins, GitLab, GitHub Actions, Azure DevOps for automated image scanning.
  • Container Orchestrators: Kubernetes, Docker, OpenShift for runtime protection.
  • Cloud Platforms: AWS (EKS, Lambda), Azure (AKS), GCP for cloud-native security.
  • Secret Management: HashiCorp Vault, AWS Secrets Manager for secure credential handling.

Example integration with GitHub Actions:

name: Aqua Security Scan
on: [push]
jobs:
  aqua-scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Run Aqua Trivy Scan
        uses: aquasecurity/trivy-action@master
        with:
          image-ref: 'docker.io/my-app:latest'
          format: 'table'
          exit-code: '1'
