DevOps + Security = DevSecOps
Integrating security into the software development process is a good practice. DevSecOps aims to ensure that security is integrated throughout the software development lifecycle, from development to deployment. Various tools are available to help security and development teams collaborate more effectively to achieve this goal.
In this article, we will look at some DevSecOps tools and which ones to use based on your unique needs and goals. Before we get into the tools required to implement DevSecOps, which is the main goal of this article, we must first understand DevOps, DevSecOps, and the distinction between the two.
Let’s get started.
Who is this article for?
DevOps and DevSecOps are interdisciplinary practices that involve the collaboration and communication of various individuals and teams within a company. As a result, the following individuals should understand DevOps and DevSecOps:
- Developers: They are in charge of writing code and creating applications. They must understand how to set up Continuous Integration and Continuous Delivery (CI/CD) pipelines and automate testing and deployment.
- Project Managers: To effectively manage the development and release of software projects, they must understand DevOps and DevSecOps practices.
- Business Stakeholders: These are the people in charge of making software development and release decisions. They must understand the advantages of DevOps and DevSecOps, such as faster time to market, high-quality software, and enhanced security.
- Operations Teams: They are in charge of maintaining and managing production systems. They must understand how to collaborate with developers to release and deploy code quickly and efficiently.
- Security Teams: These teams are in charge of ensuring an organization’s system and data security. They must understand how to incorporate security into the development process and collaborate with developers and operations teams to ensure application security.
What is DevOps?
DevOps (Development and Operations) is a software development method that seeks to close the gap between development and operations. This emphasizes collaboration, communication, and integration between software developers and IT operations teams throughout the entire Software Development Life Cycle (SDLC).
DevOps is a combination of the development (Dev) and operations (Ops) processes of SDLC.
DevOps is intended to boost efficiency, speed up the delivery of new software features, and improve software application quality. Automation, continuous integration, continuous delivery, and continuous deployment are used to achieve this. DevOps aims to enable organizations to deliver high-quality software that meets the needs of their customers quickly and reliably.
What is DevSecOps?
DevSecOps (Development, Security, and Operations) is a software development method that takes priority collaboration and communication among software development, security, and operations teams throughout the SDLC. DevSecOps aims to integrate security into the DevOps lifecycle. It automates security testing and integrates security tools and processes into the development pipeline, thereby adding security to the development process. This aids in identifying and addressing security vulnerabilities early in the SDLC. It also lowers the risk of security breaches and improves the software’s security posture.
DevSecOps aims to shift security left by embedding it into the development process. This ensures that security is not introduced at the end of the development process but is built into the structure of the software from the beginning.
Difference between DevOps and DevSecOps
DevOps and DevSecOps are two concepts in software development that are related but have different focuses.
DevOps is a collection of practices and processes aimed at improving collaboration and communication between software development and IT operations. DevOps’ primary goal is to automate the software delivery pipeline to make it more efficient, faster, and reliable.
DevSecOps is a DevOps extension that focuses on incorporating security into the software development life cycle. DevSecOps seeks to ensure that security is considered at all stages of development, from planning to deployment and maintenance. It aims to identify and mitigate security risks as early in the development process as possible so that security is built into the software from the start.

In summary, DevOps improves collaboration and communication between development and operations, whereas DevSecOps integrates security throughout the software development process.
Advantages of DevSecOps over DevOps
- Early detection of code vulnerabilities
- Increased agility and speed for security teams
- The ability to respond quickly to change and needs
DevSecOps Tools and Functions

- Development: During this stage, code is written and tested. It ensures the code’s security and functionality. Tools include Git, GitHub, GitLab, Jenkins, CircleCI, and others.
- Testing: At this stage, the code is tested to ensure that it meets the defined security requirements. The goal of this stage is to find and fix any security flaws before releasing the code. Tools include OWASP ZAP, SonarQube, Veracode, Nessus, and others.
- Deployment: At this stage, the code is deployed to the production environment. This stage’s goal is to ensure that the code is securely deployed and that the environment is configured to support the application. Available tools include Ansible, Docker, Kubernetes, and more.
- Monitoring: At this stage, the application is monitored to ensure that it continues to function securely and to identify any potential security issues. Splunk, ELK Stack, Nagios, and other tools are available.
DevSecOps workflow is intended to incorporate security into all stages of its lifecycle.
- Educate and train: Developers and security teams should be trained on security best practices and emerging threats on a regular basis. This ensures that they are up to date with the most recent security measures and can identify potential vulnerabilities during the development process.
- Automate Security Testing: Implement continuous automated security testing at every stage of the development process. Automated testing tools can detect security flaws such as SQL injection and cross-site scripting (XSS) and assist developers in resolving them before the application is released. Penetration testing should be performed on a regular basis to identify potential security breaches.
- Implement Security as Code: One of the core DevSecOps principles is that security must be treated as code. This means that security measures like authentication and authorization should be implemented through code and version-controlled alongside the application code. It helps to ensure that security is built into the development process and allows for automated testing and deployment of security features.
- Implement Least Privilege Access: Developers should only have access to the resources necessary to complete their tasks. It aids in minimizing the potential harm caused by human error or malicious activity. Introduce the use of Multi-factor authentication to ensure that only authorized personnel have access to sensitive data and systems.
- Use Containerization: This can help ensure the security of applications by isolating them from the host environment. Containers are self-contained and run in their own virtual environment, making applications easier to manage and secure.
- Secure the Pipeline: It is important to ensure that the pipeline used for continuous integration and continuous deployment is secure. This includes securing the pipeline’s servers, ensuring that only authorized personnel have access to the pipeline, and implementing secure communications between pipeline components.
So far, we’ve talked about some DevSecOps tools and their capabilities. Security is critical in the Software Development Life Cycle (SDLC) because it eliminates the burden of starting to test for security after the SDLC is completed. These tools will aid in the integration of security across all SDLC phases.
