Do you know what’s the biggest challenge for most organizations today? – Maintaining top-notch security throughout Software Development. In 2023, security is a prime concern. It’s now an integral and non-negotiable component of DevOps.

“DevSecOps, the converging force of DevOps and Security, brings a transformational shift by embedding security within the DevOps Culture.”

As we know, DevOps needs to focus on the security aspects of the SDLC; DevSecOps promises to fill the missing gaps. It is an agile approach that aims to incorporate security in every part of Software Development. But How different is it from DevOps? What are its core principles? Which tools does it use? What benefits does DevSecOps offer?

Let’s explore the world of DevSecOps through this activity guidebook!

DevSecOps Vs. DevOps: What’s The Difference?

Before diving into the specifics of DevSecOps, explore its differentiating factors from DevOps:

  • Culture: DevOps promotes shared responsibility while DevSecOps extends shared responsibility, prioritizing security.
  • Treatment of security: DevOps often addresses security at the end of the SDLC. But, DevSecOps integrates security into the pipeline.
  • Security tools: DevOps combines CI/CD pipelines with traditional security methods. However, DevSecOps requires new security tools and techniques for the CI/CD workflows.
  • Efficiency: DevOps can lead to security bottlenecks and technical debt. DevSecOps minimizes vulnerabilities in production by reducing security issue costs.
  • Automation: DevOps automates only development-related tasks. On the contrary, DevSecOps brings automation to accelerate security tasks in SDLC.

The Building Blocks of DevSecOps: How Does It Incorporate Security In DevOps?

DevSecOps incorporates security through four key pillars – Governance, People, Process, and Technology. These four pillars represent each phase of the DevOps pipeline:

#1 Governance

Governance ensures that security is a top-level consideration throughout the development process. It involves defining security guardrails that align with organizational goals. It redesigns the operational and compliance framework by establishing shared metrics and monitoring results.

#2 People

People of DevSecOps include developers, operations teams, risk analysts, and security experts. It encourages team collaboration and promotes cross-functional operations to mitigate security risks from the initial planning stages.

#3 Process

DevSecOps process embraces automation to integrate security checks into the software development processes. It also automates Security telemetry and incident response for compliance checks. This includes orchestrating an integrated process flow with an integrated backlog and pipeline.

#4 Technology

The technology aspect of DevSecOps involves implementing security tools and solutions that support the SDLC process. It automates recurring security tasks to protect the toolchain and infrastructure.

Getting Familiarized With DevSecOps Core Concepts & Principles

DevSecOps should be a natural approach for incorporating security controls into SDLC stages. So, how do we integrate security? Let’s review the core DecSecOps concepts with fundamental principles that DevOps teams should use in their SDLC workflows. Here are the main security-oriented stages of DevSecOps that occur alongside DevOps workflows.

Shift Left Security

This core DevSecOps principle involves moving security practices and checks to the earliest stages of the development process. So DevOps engineers place security at the beginning of the development lifecycle and shift it towards the left of the development workflow. It allows the teams to discover potential security risks before software delivery.

Threat Modeling

This principle outlines possible attack scenarios that can affect application performance. DevSecOps utilizes sensitive data flows to find potential mitigation options. As a result, developers can reduce the security gap and stop potential security threats beforehand.

Holistic Automation

This principle encourages DevOps teams to automate security testing for various CI/CD processes. Security analysts can also resolve security risks consistently. It helps them perform code analysis with thorough compliance checks and make well-informed decisions about eliminating potential threats.

Security As Code

This core principle of DevSecOps considers security policies and configurations as code. As it allows version control and automation, QA teams can easily configure customized automation workflows for security testing. The programmable approach improves security performance with DevSecOps tools and configuration metrics.

Continuous Improvement

DevSecOps makes continuous improvement a mandatory aspect that adds value to businesses. It iteratively improves the security capability and quality with reduced security defects and increased deployment success rates. It increases production deployment frequency and DevOps pipeline velocity while incorporating compliance feedback across iterative sprints and release cycles.

Collaborative Culture & Communication

The core concept of DevSecOps is to create open and transparent communication channels between development, security, and operations professionals. It enables teams to address security concerns proactively. As teams get to work on the same Product Goal, it fosters clear transparency and visibility among them.

Observability And Monitoring

DevSecOps emphasizes the importance of traceability and audibility. Teams can perform continuous monitoring and create observability solutions using security insights. It helps them to trace security changes and have clear visibility about the current security controls across environments.

Exploring DevSecOps Tools For Different Stages of The Framework Lifecycle
