DevSecOps With Azure: Your Secure Coding Companion

Nowadays, software development is happening at lightning speed. Everyone is in the race to build innovative applications, deliver faster features, and stay ahead of the curve. But in this digital whirlwind, one crucial element often gets left behind – security, crumbling your entire digital fortress under the weight of cyberattacks and data breaches. 

However, DevSecOps with Azure is a magic bridge connecting speed and security seamlessly. 

Azure’s built-in security tools and services identify and patch vulnerabilities in real time, neutralize threats, and ensure your digital software remains unshakable.

Security controls are compulsory in each phase of the software development lifecycle (SDLC) because they are vital to a DevSecOps ( development, security, and operations) strategy and shift-left approach.

Let’s dig out detailed steps to implement  DevSecOps With Azure:

Implementing Process Of DevSecOps With Azure: No More Security Vulnerabilities

A team performs the implementation process of DevSecOps –  developers focus on code, application operators concentrate on reliability, cluster operators focus on infrastructure, and security teams focus on overall security. Employ tools like Azure Monitor and collaborate using transparent processes to achieve optimal results in each domain. If you don’t have this team, you can take the i4 group assistance.

However, here is a DevSecOps lifecycle process:

1: The Plan Phase: Think Before You Build

This phase might not be full of fancy robots, but it’s crucial for security. Everyone gets involved here – developers, security pros, and even the operations team because early planning avoids big headaches later! Security needs right from the start, ensuring potential problems are tackled before becoming real monsters.

Design A Secure Platform

• Collaborate with security, development, and operations teams.
• Build a secure AKS platform with internal and external components.
• Utilize the AKS Landing Zone accelerator for critical design areas like security.

Integrate Threat Modeling

• Include threat modeling as a manual activity in your development process.
• Use the STRIDE threat model to identify, mitigate, and validate risks.
• Incorporate threat modeling into SDLC for early security implementation.

Apply Azure Well-Architected Framework (WAF)

• Follow WAF security best practices for identity, application, infrastructure, and more.
• Implement WAF operational best practices, especially in DevSecOps and production monitoring.
• These practices ensure security considerations are embedded early in your development lifecycle, minimizing potential issues in later stages.

2: Development Phase: Shape Your Vision

Here’s how DevSecOps helps in the development phase:

Write Strong Code

• Follow secure coding practices; use established guidelines like OWASP recommendations to avoid common vulnerabilities.
• Protect sensitive data in logs using filters and plugins.
• Use IDE tools and plugins, like SonarLint and Synk, to get real-time feedback on security issues in your code.

Control Your Code Repository

• Set branching rules using methodologies like Release flow to manage code versions and merges.
• Protect your main branch; peer reviews and pre-commit hooks are required to stop insecure changes.
• Control access by assigning roles and permissions for code access based on need.

Secure Your Container Images

• You are supposed to use minimal images; reduce the attack surface by using a lean base image, like Alpine or Mariner.
• Trust your sources and download base images from private, scanned registries.
• Scan for vulnerabilities – use tools like Trivy to analyze your images before deployment.
• Prevent containers from running as root users for extra security.

3: Building Phase: Bring It To Life

The build phase is a critical step in DevSecOps, where developers team up with site reliability engineers and security experts to ensure the security of applications.

Automated Scan Integration

The integration of automated scans, including practices like Static Code Analysis (SAST), Software Composition Analysis (SCA), and secret scanning, occurs during this phase. This integration occurs in Continuous Integration (CI) build pipelines using the security tools provided by the CI/CD platform. It is a deliberate action undertaken to enhance security in the development process.

Security Best Practices

Developers actively perform Static Code Analysis (SAST) to identify potential vulnerabilities in the application source code. Utilizing tools like GitHub Advanced Security and CodeQL is strongly recommended for efficient and thorough code scanning.

Secret Scanning

Secret scanning is employed to prevent accidental exposure of secrets. GitHub scans the code for patterns matching known secrets, sending alerts when necessary.

Software Composition Analysis (SCA)

SCA tools help to track open-source components and identify vulnerabilities in dependencies.

Infrastructure as Code (IaC) Security

IaC templates undergo security scans to minimize cloud configuration issues reaching production.

Container Image Security

During the building phase, workload images in container registries are also scanned for known vulnerabilities. Tools like Defender for Containers and Azure Policy ensure a thorough assessment.

Automated Image Building

• New images are automatically developed when updates occur to base images. Azure Container Registry Tasks can detect changes in base image dependencies and rebuild relevant application images accordingly.
• Azure Container Registry, Azure Key Vault, and notation help to sign container images digitally, which ensures that only validated images are allowed in Azure Kubernetes Service (AKS) clusters. Eventually, it provides the overall security.

4: Deployment Phase: Deploy With Confidence

Developers and operation teams collaborate for secure code deployment in the deployment phase. 

Here’s how you can perform it:

Control Pipeline Access

• Safeguard branches with protection rules, deciding who can modify them.
• Utilize environments for deployment, adding protection rules and secrets.
• Use Approvals and Gates for controlled workflow, requiring manual approvals for critical steps.
• At this phase, ensure your deployment pipeline is well-protected and approvals are in place.

Secure Deployment Credentials

• Leverage OpenID Connect (OIDC) for GitHub Action workflows accessing Azure resources without storing credentials as GitHub secrets.
• Adopt a pull-based GitOps approach for CI/CD, shifting security credentials to Kubernetes clusters, reducing risk.

Dynamic Security Testing

• Run Dynamic Application Security Testing (DAST) in deployment workflows using GitHub Actions.
• Employ tools like ZAP for penetration testing uncovering common web app vulnerabilities.
• Perform dynamic security tests during this phase to identify and address vulnerabilities.

Trusted Container Images

• Utilize Defender for Containers and Azure Policy for Kubernetes to ensure images come from trusted registries only.
