DevSecOps

DevSecOps (stands for Development, Security and Operations) is the addition of security to DevOps. It is an overall process to ensure that security is “baked in” to the entire software development cycle.

DevSecOps is a logical extension of DevOps:

• DevOps integrates operations into the develop/release cycle. DevSecOps integrates security into the develop/release cycle.
• DevOps increases the speed at which software is developed and delivered. DevSecOps increases the security with which software is developed and delivered.
• DevOps automates much of the software lifecycle. DevSecOps requires merging and automating many of the traditional practices of security engineers, operations teams, and development teams.

DevSecOps hardens the processes within, and the products of, the development cycle.

Advantages of DevSecOps

DevSecOps brings several advantages to the software development process, particularly when it comes to web security.

1. Early Identification and Mitigation of Security Risks: One of the key advantages of DevSecOps is its proactive approach to security. Unlike traditional development approaches, where security checks are often performed as an afterthought, DevSecOps integrates security right from the beginning of the software development cycle. Security considerations are embedded into every stage of development, from design and coding to testing and deployment. By identifying and addressing security risks early in the process, DevSecOps minimizes the chances of vulnerabilities going undetected until the production phase. This significantly reduces the potential for security breaches and data leaks, enhancing the overall security posture of web applications.
2. Increased Speed and Security: DevOps is known for its focus on accelerating the development and delivery of software products. DevSecOps takes this a step further by ensuring that speed does not come at the cost of security. By automating security practices throughout the development cycle, DevSecOps achieves a delicate balance between speed and security. Continuous security testing and automated security checks help maintain the development momentum while ensuring that web applications meet the highest security standards. As a result, organizations can deliver software faster without compromising on security, creating a competitive advantage in today’s fast-paced digital landscape.
3. Minimizes Expenses: Software bugs and other deficiencies are cheaper to fix when they are discovered earlier in the development cycle. A DevSecOps culture encourages the integration of preventative security measures into the pipeline, including such things as vulnerability scans and other practices. With these in place, potential security problems can be identified and addressed earlier, which minimizes overall expenses to the organization.
4. Compliance Adherence and Regulatory Requirements: Web applications often handle sensitive user data, making compliance with data protection and privacy regulations imperative. DevSecOps helps organizations meet regulatory requirements by automating security controls and checks. By integrating compliance considerations into the development process, DevSecOps ensures that web applications adhere to relevant regulations. This proactive approach not only reduces the risk of non-compliance penalties but also instills trust in customers and partners by demonstrating a commitment to data privacy and security.
5. Continuous Improvement and Learning: DevSecOps promotes a culture of continuous improvement and learning in the context of web security. Through continuous monitoring and feedback loops, organizations gain valuable insights into their security posture and potential areas for improvement. By analyzing security metrics and data, organizations can identify patterns, trends, and emerging threats. This knowledge is used to refine security practices and strategies continually, ensuring that the organization remains resilient in the face of evolving cyber threats.

Benefits of DevSecOps

Infrastructure Hardening

Infrastructure as Code (IaC) is a fundamental component of DevSecOps. It is the management of infrastructure components (subnets, networks, servers, databases, services, etc.) through code. This has many advantages, including the ability to fortify the infrastructure automatically. Usually, an organization which uses IaC will also use immutable IT infrastructure.

Server settings, port closures, protocol closures, NACLs, security group settings, and other configurations can all be automated. This not only increases security, it is also required for some forms of compliance. As a result, a wide variety of tools have become available for various types of IaC hardening.

Pipeline Hardening

DevSecOps mandates the automation of security throughout the development and delivery cycle. A variety of tools have become available to harden the CI/CD pipeline. For example, if the pipeline builds containers, then the containers can be hardened immediately afterwards. After applications are built, they can be run through vulnerability scans.

APIs can be tested to ensure that they trigger alerts and throw exceptions when out-of-bounds inputs are received. Software that passes should be delivered into environments that themselves have been hardened and verified, for example by host-based firewalls, data loss prevention agents, and so on.

Application Hardening

Application hardening in DevSecOps involves proactively preventing common security pitfalls. Code can be set up to automate security practices at each environment of the operational stack, ensuring consistent security measures throughout the application’s lifecycle.
For example, many of the OWASP Top 10 Vulnerabilities can be remediated through automation:

• Code that installs applications automatically and requests/applies trusted certificates for web endpoints, app-to-app communication, and app-to-database communication.
• Code that installs framework updates (Java and NodeJS) as part of an agent-based desired state configuration management.
• Code that creates auditable exceptions in applications that show security attacks, then alerts when those exceptions are raised.
• Code that ensures only strong cipher suites, protocols, and hashes are used in the application stack, and that all insecure methods are disabled at the OS whenever possible.

Traditionally, security is one of the last things that gets considered during the development cycle. Engineers tended to create apps first, and then test them for vulnerabilities as an afterthought. DevSecOps mandates that good security practices should be enforced all through development, and not only in production.

Importance of DevSecOps in Web Security

In the context of web security, DevSecOps plays a crucial role in safeguarding web applications and data. By incorporating security practices from the outset, potential vulnerabilities are addressed before they can be exploited by malicious actors. This proactive approach significantly reduces the risk of security breaches and data leaks that could compromise the trust of users and damage an organization’s reputation.

Conclusion

DevSecOps represents a significant shift in the software development paradigm, emphasizing the importance of integrating security into every phase of the development lifecycle. By adopting DevSecOps principles, organizations can achieve faster and more secure software delivery while minimizing the risk of security vulnerabilities. The examples of infrastructure, pipeline, and application hardening demonstrate how DevSecOps enforces good security practices throughout development, leading to robust and resilient software products.

In the context of web security, DevSecOps is essential for protecting web applications, sensitive data, and user trust in an increasingly interconnected and digital world. Embracing DevSecOps is not just a trend but a necessary evolution for organizations seeking to build secure, reliable, and high-quality software products.
