Difference Between DevOps and DevSecOps

Here's a fact that sets the stage: 8 out of 10 organizations are implementing DevOps, according to Puppet's State of DevOps report. Now, consider this - in a rapid leap from 27% in 2020 to a significant 36% now, organizations are not just doing DevOps but also implementing DevSecOps.  

The landscape of IT is changing, and it's changing fast. With the majority adopting DevOps and a growing chunk integrating security through DevSecOps, the question arises: 

What's behind the two? 

 

Common Ground: Starting from the Same Page

DevOps and DevSecOps both aim for efficient software development. They share the basics: collaboration, automation, and efficiency. It's a culture where development and operations teams work together, sharing responsibility and striving for continuous improvement.

 

A Shared Collaborative Effort 

DevOps is about developers and operations collaborating. In DevSecOps, it's the same with developers teaming up with the security crew. The focus is on building systems from the start, not in silos or as an afterthought; that's where a collaborative culture is an everyday act. 

Efficiency through Automation

DevOps maximizes efficiency via automated software delivery, spanning coding to deployment. In DevSecOps, automation integrated security seamlessly, ensuring continuous testing and proactive threat detection. Both prioritize automated workflows, harmonizing speed and security in software development.

Proactive Monitoring

In both DevOps and DevSecOps, active monitoring is essential. DevOps emphasizes early production testing for reliability and quick updates. DevSecOps adds a security layer with internal and cloud monitoring, preventing vulnerabilities and unauthorized access. Proactive monitoring ensures efficient and secure development in both practices.

User-Focused Philosophy

Both approaches, DevOps and DevSecOps, share a core commitment to meeting customer needs and delivering value. Through a continuous integration of customer feedback, these methodologies prioritize features and enhancements that resonate with user expectations. The result is the creation of more user-centric products and services.

 

Core Differences: What Sets Them Apart 

DevSecOps isn't just DevOps with a security patch. It's a mindset shift. Security isn't an add-on; it's embedded from the start. Think integration of security tools, threat modeling, and a proactive security approach. DevSecOps means business when it comes to safeguarding your digital assets.

 

Approach

DevOps embodies a culture; DevSecOps, a mindset. DevOps prioritizes communication, automation, and visibility. DevSecOps integrates cybersecurity into continuous development, emphasizing tools, speed, efficiency, and security through automation for rapid organizational adaptation.

Objective

DevSecOps aligns with DevOps principles, emphasizing speed with security. DevOps accelerates organizational pace to outshine competitors, safeguarding against errors and external threats. The focus is error avoidance and integrating security into processes, ensuring seamless, interconnected pipeline resilience.

Focus Factor

DevOps centers on development and operations, championing speed through automation and cross-team collaboration. In contrast, DevSecOps, with its security-centric focus, assigns greater significance to manual processes like change management and code reviews, ensuring an approach to safeguarding software integrity.

Team Dynamics

DevSecOps structures differ, requiring a blend of DevOps and DevSecOps talents. If your company lacks dedicated teams, merging them is the initial DevSecOps step. DevSecOps pros span both domains, while traditional security experts specialize. DevOps engineers master diverse tools, and DevSecOps engineers, beyond Linux, embed security in the cloud, excelling in problem-solving, cross-departmental coordination, and policy definition.

Security Onset

DevSecOps transcends mere security—a holistic approach to every application development and deployment facet. From embedding security from the outset to continuous monitoring and automated remediation, DevSecOps extends beyond the traditional boundaries of DevOps. It demands collaboration across previously distinct groups, intertwining developers and IT operations. Security isn't an add-on; it's an integral and ongoing aspect of DevOps, commencing at the inception of the development pipeline.

Overcoming Hurdles 

DevOps confronts security-related challenges—transitioning from infrastructures to microservices, streamlining processes, and navigating limited customer feedback. In DevSecOps, akin challenges surface, accentuated by tool-centric testing demands, occasional developer knowledge gaps, and little integration with Appsec tools. The shared terrain includes pipeline friction and the weight of developer overload, presenting intricate landscapes for both methodologies.

 

Smooth Transition: Moving to DevSecOps

Considering the shift from DevOps to DevSecOps? More than half (54%) chose DevSecOps practices to amp up security, quality, and resilience—proving it's go-to for a safer and more robust software development approach.

Here's your checklist. It's not rocket science, but it's critical.

 

Assess Current DevOps Practices

Look at what you're already doing in the DevOps arena. Evaluate your current practices – what's working like a charm, and where might there be room for improvement? This initial self-assessment sets the stage for the rest of your DevSecOps journey.

Understand Security Requirements

Now, let's talk about security. It's not a one-size-fits-all deal. Understand the specific security needs of your project. What kind of data are you dealing with? What are the potential threats? Tailor your security approach to fit your unique requirements like a custom-made suit.

Promote Security Awareness

Spread the word – security is everyone's business. Foster a culture of security awareness. Make sure everyone on the team, from developers to operations, understands the importance of security in what they do. It's not just a checkbox; it's a shared responsibility. 

Involve Security Experts

Time to call in the experts. Bring security specialists into the mix. Their insights are invaluable. They can help you identify potential vulnerabilities, recommend best practices, and level your security game. 

Review and Update Policies

Policies can't be set in stone. Regularly review and update them to keep pace with the evolving security landscape. If your policies are the guiding principles, think of this step as giving them a refresh to ensure they're up to date and in sync with your current goals.

Integrate Security Throughout the Lifecycle

Let's weave security into the very fabric of your development lifecycle. From coding to deployment, make it a seamless part of the process. That way, security isn't an afterthought; it's a companion in every step of the journey.

Implement Security Testing

Introduce robust security testing. Identify potential weak spots before they become actual problems. It's like having a superhero safeguarding your software against invisible threats.

Post-Deployment Penetration Testing

As organizations shift to DevSecOps, post-deployment penetration testing becomes pivotal. This continuous analysis identifies evolving threats, assesses patch effectiveness, and simulates real-world attacks, to integrate security into the CI/CD pipeline for an efficient transition.

Automate Security Controls

Why do things manually when you can automate them? Set up automated security controls. It not only saves time but ensures consistency. Automation is your ally in maintaining a robust security posture.

Continuous Monitoring and Incident Response

Security is an ongoing story. Set up continuous monitoring. Keep a vigilant eye on your systems. And when something does raise an eyebrow, have an incident response plan in place. It's about being proactive, not reactive.

Taking Action on Anomalies

Beyond mere detection, it's crucial to augment your incident response plan with specific actions tailored to the corresponding incident behavior. This proactive approach ensures that your security measures evolve with the changing threat, moving beyond detection to effective response and mitigation.

Collaboration and Cross-Team Communication

Foster collaboration between teams. Developers, operations, security – everyone needs to be on the same page. Communication is key. It's not just about sharing information; it's about creating a united front against potential threats.

Evaluate and Improve

Last but certainly not least, the cycle continues. Regularly evaluate how things are going. What's working well, and where can you fine-tune? Improvement is a constant journey. Keep evolving, keep enhancing – that's the DevSecOps spirit.

Meeting Compliance Requirements

Dedicated compliance is vital for meeting regulatory demands. Incorporate industry standards like GDPR, HIPAA, or PCI DSS. Regular audits and documentation ensure your security practices align with these regulations, reducing legal and financial risks.

Policies for Security 

Craft precise security policies to guide every aspect of DevSecOps. Specify user access controls, encryption standards, data handling protocols, and incident response procedures. These straightforward guidelines not only strengthen security but also foster a culture of accountability and resilience within your organization.

 

The Wrap: Striking the Balance

DevOps drives efficiency for 80% of organizations, and the addition of DevSecOps is backed by a striking fact: 96% see value in automating security and compliance. While DevOps accelerates, allowing a 60% faster code release, it comes with a caveat—almost half deploy vulnerable code due to time constraints. 

Integrating DevSecOps isn't a choice but a strategic necessity, emphasizing the benefits of seamless security and cautioning against prioritizing speed over safety.

Also, almost 9 out of 10 DevSecOps adopters said that adding security sped up or, at the least, had no negative impact on software delivery.

DevOps accelerates, but DevSecOps secures. It's not exclusion; it's integration. The stats affirm an apparent reality—speed without security is a risk too significant in the digital landscape.
