Devsecops vulnerability management

What is DevSecOps?

DevSecOps is a software development methodology that integrates security practices into DevOps, with the aim of creating a culture of shared responsibility for security among all stakeholders involved in the software development process. It is a mindset that promotes the early identification and mitigation of security risks throughout the software development lifecycle using:

  • Shift-left approach
  • Automation
  • Collaboration
  • Continuous improvement (CI)
  • Continuous Development (CD)

What is DevSecOps vulnerability management with CI/CD and why it is important?

DevSecOps vulnerability management is an integral part of the DevSecOps framework that focuses on the continuous identification, classification, prioritization, and remediation of software vulnerabilities throughout the software development lifecycle (SDLC). By integrating security practices into the DevOps process, DevSecOps aims to minimize the risk of security breaches and ensure that applications are built securely from the ground up.

By incorporating following vulnerability practices into the DevSecOps environment framework, organizations can proactively manage vulnerabilities, reduce their attack surface, and ensure that their applications and infrastructure remain secure throughout their lifecycle.

Continuous Vulnerability Scanning

Regularly scan code repositories, applications, and infrastructure to identify vulnerabilities in software components, dependencies, and configurations. This includes both static (SAST) and dynamic (DAST) application security testing to detect potential security flaws.

Vulnerability Classification

Categorize identified vulnerabilities based on their type, source, and impact on the application or infrastructure. Common vulnerability classification schemes include the Common Vulnerabilities and Exposures (CVE) system and the Common Weakness Enumeration (CWE) taxonomy.

Risk Assessment and Prioritization

Assess the risk associated with each identified vulnerability, considering factors such as the potential impact, exploitability, and the affected assets’ criticality. Prioritize remediation efforts based on risk levels, typically following the Common Vulnerability Scoring System (CVSS) for consistent risk scoring and prioritization.

Patch Management and Remediation

Develop and deploy patches or other mitigation techniques to address identified vulnerabilities promptly. In a DevSecOps environment, this process is integrated into the development pipeline, allowing for faster and more efficient vulnerability remediation.

Verification and Validation

Confirm that the applied patches or mitigations have effectively resolved the identified vulnerabilities. This may involve rescanning the affected components and reviewing the remediation efforts.

Continuous Monitoring and Improvement

Regularly monitor the effectiveness of the vulnerability management program and update processes, tools, and techniques to adapt to the evolving threat landscape and organizational needs.

What is Shift-left approach in DevSecOps?

Security is integrated into the development process from the very beginning, rather than being an afterthought.


Automation is used to accelerate the identification and mitigation of security risks, enabling developers to focus on coding while security processes run in the background.


DevOps and security teams work together throughout the development process to ensure that security requirements are met, and security issues are addressed in a timely manner.

Continuous improvement (CI)

DevSecOps is an iterative process, where feedback is continuously gathered, and improvements are made to the security practices.

Continuous Development (CD)

Continuous development in DevSecOps is the process of continuously delivering new software features and updates while ensuring that security is integrated into every step of the development process. It involves an iterative approach to software development, where new features are developed, tested, and deployed in small increments rather than in large releases.

DevSecOps best practices for vulnerability management in CI/CD

What is vulnerability management in DevSecOps?

Vulnerability management is an essential aspect of DevSecOps, as it helps to reduce the risk of security breaches and ensure that software systems remain secure and resilient in the face of evolving security threats. Vulnerability management in DevSecOps is the process of identifying, prioritizing, and mitigating vulnerabilities in software systems to reduce the risk of security breaches and protect the confidentiality, integrity, and availability of the system. It is an ongoing process that involves continuous monitoring and testing of software systems for vulnerabilities and applying remediation measures to reduce or eliminate the risks posed by these vulnerabilities.

The vulnerability management process in DevSecOps typically involves the following steps:

  1. Vulnerability scanning: Automated vulnerability scanning tools are used to identify vulnerabilities in software code, configurations, and dependencies. These tools analyze the code and identify potential vulnerabilities based on known attack patterns and best practices.
  2. Vulnerability assessment: Once vulnerabilities are identified, DevSecOps teams assess the severity and potential impact of each vulnerability to prioritize remediation efforts. This involves assigning a risk score to each vulnerability based on factors such as its likelihood of exploitation, potential impact on the system, and ease of mitigation.
  3. Remediation planning: DevSecOps teams develop a remediation plan to address the vulnerabilities identified in the vulnerability assessment. This plan typically includes the prioritization of vulnerabilities, the assignment of tasks to team members responsible for remediation, and timelines for remediation efforts.
  4. Remediation implementation: DevSecOps teams implement remediation measures, such as applying security patches, updating dependencies, or modifying the code to remove the vulnerability.
  5. Verification: After remediation measures are implemented, DevSecOps teams conduct testing and verification to ensure that the vulnerabilities have been successfully mitigated and that the system is secure.
  6. Ongoing monitoring: DevSecOps teams continuously monitor software systems for new vulnerabilities and apply remediation measures as needed to maintain a secure and resilient system.
