The DevSecOps pipeline integrates security practices into the DevOps process, emphasizing continuous delivery. It treats security engagement as an active component of the software development life cycle (SDLC), using standard DevOps practices such as Continuous Integration and Continuous Delivery (CI/CD) for ongoing testing and code verification.

DevSecOps Pipeline

DevSecOps is a process that integrates security practices into the DevOps process and characterizes a security-centric software development life cycle (SDLC) that emphasizes continuous delivery. In the traditional approach, security in DevOps is often given less importance and appears towards the end of the SDLC.

This can be highly frustrating as discovering security vulnerabilities late in the SDLC can lead to significant delays. DevSecOps advocates for treating security engagement as a significant and active component of the entire software development life cycle (SDLC). The approach uses standard DevOps practices such as Continuous Integration and Continuous Delivery (CI/CD) to enable ongoing testing and verification of code correctness throughout the Agile development process.

What is the CI/CD pipeline?

CI/CD stands for Continuous Integration/Continuous Deployment. It’s a way of developing software where developers keep adding their code changes to a shared repository. After writing and integrating the code, they push it to a common repository like Git. AFter that, tools such as Jenkins take over and perform tasks like system testing, security checks, and email notifications.

This allows developers to take time off while Jenkins handles the routine tasks. The CI/CD pipeline tool makes sure that when a code change is made, the updated system is shared with others, saving time and effort.

What is the DevSecOps pipeline?

The software development lifecycle involves several steps and stages. In the DevSecOps pipeline, these steps are highly automated, with an emphasis on security and collaboration among teams. This approach ensures that the software remains up-to-date with the latest technology.

DevSecOps is all about integrating security measures into the software development life cycle. A DevSecOps pipeline is essentially a collection of security practices that are seamlessly integrated into your SDLC. The main goal of this pipeline is to make building, testing, and deploying secure software faster and more efficient.

Importnace of DevSecOps pipeline

Our technology-rich lives are constantly under threat and everyone knows that. So, it is important to incorporate security measures early in our Software Development Life Cycle (SDLC) to avoid risking our technology-driven livelihoods.

Security breaches are a significant threat that many governments and organizations face today. These breaches lead to a loss of consumer trust and cause substantial financial losses annually. Waiting until the last minute to address security concerns in your product can lead to costly iterations.On the contrary, embedding your product with gold standard security measures significantly reduces the likelihood of discovering unexpected issues at the eleventh hour.

Adopting a DevSecOps approach not only fortifies your product but also enhances your credibility in the market, fostering consumer trust. Considering these factors, it becomes evident that integrating DevSecOps is a pivotal step in the continuous paradigm, ensuring the robust security of your technology

Your product is baked with high-security standards, reducing the probability of unexpected issues. By adopting this approach, you can enhance your credibility in the market while building consumer trust.

With this in mind, let’s now discuss how DevSecOps fits into the continuous paradigm.What role can DevSecOps play in CI/CD Pipeline?

What role can DevSecOps play in CI/CD Pipeline?

Security measures can be easily integrated into the CI/CD pipeline. When a developer triggers a code build, a CI/CD pipeline tool takes care of crucial processes, such as pushing the code to a shared repository and notifying other team members.

Additionally, the tool can check for external libraries in the project, verify their legitimacy, identify potential vulnerabilities, and assess any license risks.

The process checks if any sensitive information like passwords or credentials is present along with the code in a Git repository, and sends notifications if it finds any. Security tools also scan container images for vulnerabilities before they are added to the CI/CD pipeline.

There are several tools available for these purposes, and they can be easily integrated into the DevOps CI/CD pipeline.

What are the steps involved in DevSecOps Pipeline?

The DevOps Pipeline has phases like Plan, Code, Build, Test, Relase and Deploy. In each of these pipline process security checks are constantly done to ensure maximum rigidity.

Developement

In the software development process, the developer writes code using an Integrated Development Environment (IDE), and then stores the code in a repository. The hosting platform for the code repository can be GitHub, as shown in the diagram above.

To ensure the security of the code, IDE plugins and linters are used. These tools help to identify any programming errors, bugs, syntactical and stylistic mistakes, and malformed constructs in the source code. They also help developers follow best practices while writing code.

Source Code Repository

After completing the development phase, the code is saved in the repository, which is hosted on GitHub. However, there is a possibility that developers might accidentally or deliberately add confidential information like passwords, API tokens, and other sensitive data to the repository.

To avoid these situations, secret scanning tools are used to scan the repository and detect any hidden secrets. This helps in taking necessary actions to address and resolve any security concerns.

Testing

After scanning for secrets on GitHub, the next step in the pipeline is testing.

Security Measure: SAST (Static Application Security Testing)

During the testing phase, the application’s source code is scanned for security vulnerabilities using a technique called SAST (Static Application Security Testing). SAST helps identify issues such as SQL Injection, Input validation issues, Stack/Buffer overflow, and more.

Security measure 2: SCA

During the testing phase, a security measure called Source Composition Analysis (SCA) is used to identify vulnerabilities in Open Source Software (OSS) utilized by the application. For example, an application might be using an outdated jQuery version that is susceptible to XSS. SCA scans the code and detects such issues within the OSS being utilized, addressing them accordingly.

Build

During the build phase, after the testing phase, the focus shifts to using tools like Docker, Terraform, and Kubernetes. Docker images are created and then uploaded to the repository. To manage multiple Docker images through a container orchestration tool, Kubernetes is commonly used.

Infrastructure as Code (IaC) is leveraged to create Kubernetes clusters, with tools like Terraform taking a significant role. Overall, this phase centers around the use of Docker, Kubernetes, and Terraform.

Security Measures:

• Dockerfile Scanning: This involves examining the Dockerfile for potential misconfigurations, such as avoiding the use of the sudo command, ensuring the use of trusted base images, incorporating Healthcheck instructions, and more.
• Docker Image Scanning: The Docker image undergoes scanning to identify and address any vulnerabilities present.
• IaC Scanning: The Terraform scripts and HelmChart are scrutinized for potential misconfigurations during this phase.

Deployment

During the Deployment phase, the Docker image is put into action to run the application. There are several security measures to ensure that the application is secure during this phase. These measures include:

• DAST (Dynamic Application Security Testing): DAST involves scanning the application during runtime using tools like BurpSuite, OWASP ZAP, Acunetix, etc. This process utilizes the DAST tool to scan the application for vulnerabilities.
• Infrastructure Scanning: This entails scanning the entire infrastructure to identify and address potential vulnerabilities such as unnecessary open ports and outdated services.
• Docker Image Scanning: The Docker image is also scanned to identify and address any vulnerabilities present.

Additionally, there is a Compliance Check process in this phase. Compliance checks in this context primarily involve verifying server hardening in alignment with the CIS Benchmark, serving as an auditing standard and reference.

Monitoring

During the monitoring phase, the entire infrastructure is overseen by gathering, consolidating, and analyzing data from various sources. The main objective is to maintain uptime, identify any irregularities, and detect any malicious activities within the network or infrastructure.

Building the DevSecOps Pipeline

Companies have the flexibility to construct their own DevSecOps pipelines, tailored to their specific requirements and needs. Developing a customized DevSecOps pipeline offers professionals complete control over their tools, processes, and integrations.
