What Is DevSecOps? What Does It Stand For?

The industry has been abuzz with the term ‘DevSecOps’ in recent years. It is an extension to the process of DevOps, and stands for Development, Security, and Operations. Expanding on each of these terms in DevSecOps:

Dev – the process of planning, coding, building, and testing software

Sec – the process of introducing and prioritizing security earlier in the SDLC

Ops – the process of deploying software and continuously monitoring it’s performance

Defining DevSecOps

DevSecOps can be defined as the process of integrating security best practices within every stage of the software development lifecycle. This approach emphasizes the need for a cultural shift (or change in mindset) within the organization. 

A change advising teams to ‘automate security testing’ and share the responsibility of application security and infrastructure security between three teams within engineering – development, operations, and security.

Introduction To DevSecOps

Born from the school of thought which emphasizes the need for more secure software, DevSecOps is an approach to culture, automation, and platform design that promotes Security (Sec) as a shared responsibility between Development (Dev) and Operations (Ops).

Combining these three disparate teams into a single, cohesive process fosters collaboration and enforces security measures at every stage of the software development lifecycle, from early design and development to deployment and continuing operations.

Addressing The Need For Security In Software Development with DevSecOps

The need for DevOps Security arises from several factors, including the increasing frequency and sophistication of cyber threats, the growing reliance on software systems, and the potential impact of security breaches on individuals, organizations, and society as a whole.

Looking for strategies to secure your software delivery?

Why is ‘Security' important in DevOps?

Here are some key drivers of security in software development:

  1. Protection against Cyber Threats
  2. Safeguarding Sensitive Data
  3. Compliance with Regulations
  4. Preservation of Business Reputation
  5. Minimizing Financial Losses
  6. Ensuring Software Reliability
  7. Mitigating Operational Risks
  8. Meeting Customer Expectations

Key Principles And Goals Of DevSecOps

To reiterate, DevSecOps was born out of the ideology of ‘Shift-left Security‘, meaning security practices should be implemented early and continuously within the DevOps workflow. The core principles of DevSecOps include security automation, continuous security, and cross-functional collaboration.

  1. Security automation – allows for consistent and repeatable security practices, such as automated testing, vulnerability scanning, and configuration management
  2. Continuous security in CI/CD – ensures that security controls are continually assessed and adjusted as needed within CI/CD pipelines
  3. Cross-functional collaboration – fosters communication and knowledge sharing among different teams, breaking down silos and enabling a holistic approach to security.

By addressing security early and continuously not only reduces the risk of vulnerabilities and breaches but also enhances the overall speed and efficiency of the software development process. By integrating security into DevOps practices, organizations can achieve a balance between speed, agility, and robust security measures, leading to more secure and reliable software applications.

Understanding DevOps vs DevSecOps

While DevOps is primarily concerned with streamlining the processes of development and operations, DevSecOps extends to include security as an integral part of the entire process. DevSecOps places a strong emphasis on identifying and addressing security vulnerabilities and risks from the beginning, promoting a culture of security awareness, and ensuring that security is not an afterthought but a core consideration throughout the software development and delivery lifecycle.

How does DevSecOps differ from traditional DevOps?

Read this blog to learn about DevOps vs DevSecOps in more detail.

DevSecOps - collaboration between Developers, Security, Operations
But to understand DevSecOps better, you need to first start from inception and understand the role of DevOps and why it was needed.

Overview Of DevOps & Its Core Principles

The term ‘DevOps’ was coined by Patrick Debois in 2009, with the aim of fool-proofing the shortcomings of yesteryear software development process and practices, namely – SDLC, Waterfall model, Agile Development & Scrum among others.

DevOps addressed those issues with a unique approach approach to software development and delivery that emphasizes mainly on two things:

  1. Effective collaboration between different team members, and 
  2. Improved automation in the overall software development cycle. 

In order to improve the overall quality and reliability of software, DevOps promotes the need to constantly collect feedback by Continuously Monitoring the application for performance. But most importantly it introduced revolutionary practices such as Continuous Integration (CI), Continuous Deployment and Continuous Delivery (CD).

By improving communication, and automating manual processes, teams can break down organizational silos, thus helping them deliver better software, faster.

What Are the Benefits of Following the DevOps Methodology?

Organizations and teams benefit hugely from adopting the DevOps methodology. Some of them are: 

  1. Frequent and reliable software updates due to the emphasis on Automation in general, CI and CD
  2. Improved communication and better collaboration leading to faster issue resolution, reduced bottlenecks, and improved overall efficiency
  3. Improved software quality thanks to continuous & automated testing, early bug detection and establishment of formal QA practices
  4. Improved developer productivity by automating manual tasks, such as build, test, and deployment processes
  5. Greater reliability and stability thanks to reduced human intervention and increased adoption of infrastructure as code (IaC)
  6. Continuous feedback and improvement by instilling a culture of continuous learning and improvement
  7. Scalability and flexibility in deploying and managing applications with ease based on demand 
  8. Cost Optimization thanks to reduced manual effort, and improved resource utilization

What Is the Role of Security in DevOps?

In the context of Security, it is essential to understand that DevOps is the foundation upon which DevSecOps is built. DevOps promotes collaboration between development (Dev) and operations (Ops) teams, breaking down silos and fostering a culture of shared responsibility. DevSecOps aims to integrate Security practices deeply and strongly into the DevOps workflow. 

What Are the Challenges & Risks Associated With Neglecting Security in DevOps?

Neglecting security in DevOps can introduce various challenges/risks that can have severe consequences for organizations. Here are some of the key challenges and risks: 

  1. Increased Vulnerability to Cyber Threats
  2. Higher Risk of Data Breaches
  3. Compliance and Legal Issues
  4. Operational Disruptions and Downtime
  5. Increased Remediation Costs
  6. Reputation and Customer Trust
  7. Lack of Accountability and Responsibility
  8. Missed Business Opportunities

To mitigate these challenges and risks, organizations should prioritize integrating application security throughout the entire DevOps process.

What led to the Rise in Shift-left Mentality?

By recognizing the importance of application security integration early and continuously throughout the software development lifecycle, DevSecOps builds upon DevOps principles by integrating security considerations, tools, and practices into the development and delivery process.

What does "Shift-left" mean in DevSecOps?

It emphasizes “shifting left”, meaning that security is addressed as early as possible in the development cycle, rather than being treated as an afterthought or a separate phase. This collaborative and integrated approach enables organizations to achieve a balance between speed, agility, and robust security measures, resulting in more secure and reliable software applications.

Key Processes & Tools in DevSecOps

Key Processes In DevSecOps

Here are the key processes typically involved in DevSecOps:

1. Code Analysis

Code analysis involves examining the source code for security vulnerabilities, coding flaws, and adherence to coding standards. Static Application Security Testing (SAST) tools analyze the codebase to identify potential weaknesses and vulnerabilities thereby helping developers fix security issues early in the development lifecycle.

2. Change Management

Change management is the process of planning, coordinating, and controlling changes to the software system. Changes that impact security such as, code modifications, infrastructure updates, or configuration changes, should be properly reviewed, approved, and tracked. This helps maintain the security posture and stability of the system throughout its lifecycle.

3. Compliance Management

Compliance management involves ensuring that the software and its development processes adhere to relevant regulations, industry standards, and security best practices. This involves assessing compliance requirements, implementing necessary controls, conducting audits, and documenting compliance activities. Compliance management helps organizations meet legal obligations and mitigate security risks.

4. Threat Modeling

Threat modeling is a proactive approach to identifying and mitigating security risks by systematically identifying potential threats, vulnerabilities, and attack vectors to the software system. By analyzing the system’s architecture and design, threat modeling helps organizations prioritize security controls and countermeasures, ensuring that security risks are addressed effectively.

5. Security Training

Security training is an essential component which involves educating developers, operations personnel, and other stakeholders about security best practices, secure coding techniques, emerging threats, and industry standards. Security training helps raise awareness, improve knowledge, and promote a security-focused mindset among the team members. It includes various techniques such as Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), and Software Composition Analysis (SCA).

6. Incident Response and Recovery

Incident response processes help organizations establish a response plan, assign roles and responsibilities, and conduct drills to practice incident response procedures. The process includes detection, analysis, containment, eradication, and recovery steps to handle security incidents effectively.

7. Vulnerability Management

The vulnerability management process focuses on identifying, prioritizing, and remediating vulnerabilities. It includes scanning for vulnerabilities using automated tools, assessing their severity and impact, and establishing a process for timely remediation. This process often involves coordination between development and operations teams to address vulnerabilities promptly.

8. Secure Configuration Management

Secure configuration management ensures that application and infrastructure components are configured securely. It involves establishing security baselines, following industry best practices for secure configuration, and regularly reviewing and updating configurations to address security vulnerabilities and compliance requirements.

9. Continuous Integration and Deployment (CI/CD)

DevSecOps integrates security practices into the CI/CD pipeline. Security tests, vulnerability scanning, and compliance checks are automated and integrated into the build and deployment processes. This ensures that security assessments are performed consistently and vulnerabilities are addressed before deployment.

10. Continuous Monitoring

Continuous monitoring involves tracking and analyzing security events, application behavior, system performance, and user activities in real-time. It helps detect anomalies, security incidents, and potential vulnerabilities. Monitoring systems generate alerts for suspicious activities, providing valuable insights for incident response and security improvement.

Each of these processes contribute to the overall security posture of the software development and deployment lifecycle. They help identify and mitigate security risks, ensure compliance with regulations, and foster a culture of security awareness and accountability.
