DevSecOps – The Approach to Security by Design

Software development has evolved significantly in recent years. Processes like Agile development and DevOps along with technologies like cloud computing have made it quicker and more efficient than ever and this has largely been beneficial.

Developers can streamline the process and expedite a software release cycle, and users can get their hands on the finished product in a shorter period of time.

However, this can pose a problem from a cybersecurity standpoint because security standards aren’t always able to keep pace. In fact, 65 percent of developers say that a rushed release results in mobile app vulnerabilities.

It’s a major problem that needed addressing, and that’s where DevSecOps comes in.

What’s the Purpose of DevSecOps?

According to software engineer Shannon Lietz, “The purpose and intent of DevSecOps is to build on the mindset that ‘everyone is responsible for security’ with the goal of safely distributing security decisions at speed and scale to those who hold the highest level of context without sacrificing the safety required.”

It’s a proactive approach to cybersecurity where secure practices are embedded into the entire lifecycle of software development. DevSecOps represents an underlying philosophy where security is weaved into the very fabric of development rather than merely being applied after the fact.

In other words, it’s security by design. While there’s a lot that goes into it, this methodology involves some core principles.


Just like with DevOps, speed and efficiency play a major role in DevSecOps. So it should come as no surprise that automation is a central tenet.

This is done by implementing cutting-edge security controls and automated testing throughout the entire development lifecycle. Some specific techniques include:

  1. Logging and event monitoring
  2. Configuration and patch management
  3. User and privilege management
  4. Vulnerability assessment
  5. Compliance with industry standards

Team Collaboration

Relationships between the members of a dev team are extremely important. With DevSecOps, there’s the understanding that no one operates within a vacuum and that team collaboration is essential to the overall quality of the finished product.

That’s why there’s an emphasis on eliminating silos between those responsible for software development, security and so on. Instead, security is viewed as a team responsibility where individual members strive for optimal security as a collective unit.

This brings us to our next point.

Shared Threat Intelligence

Another key part of the DevSecOps manifesto is that team members should openly exchange security-related information with one another rather than keeping it to themselves. If a vulnerability is suspected, it’s critical that others are made aware of it as quickly as possible.

Lietz summarizes it well by saying, “The mindset established by DevSecOps lends itself to a cooperative system whereby business operators are supplied with tools and processes that help with security decision making along with security staff that enable use and tuning for these tools.”

In other words, everyone’s in on security and intelligence flows freely. This way threats can be promptly addressed, thus reducing the chances of major security flaws.

Continuous Security Monitoring

The manifesto also calls for 24×7 proactive security monitoring, meaning you don’t wait for an incident to occur and then react to it. Rather you consciously seek out vulnerabilities before cyber attackers have the chance to exploit them.

This involves a “not if but when” approach to security. Threats are imminent, so they should be sought out.

In this regard, team members are basically putting themselves in the shoes of the enemy and thinking like they would. And it’s this mindset that makes DevSecOps so effective. The fact that it’s such an aggressive approach is what stamps out many issues before they have the chance to fully materialize.

The Benefits

At this point, we have a basic understanding of the purpose of DevSecOps as well as its underlying principles.

But how does this benefit your organisation? And what practical advantages does it offer?

Better Overall Security

First of all, you can expect tighter security from the top down. Because it’s a fundamental priority throughout the entire development lifecycle, there tends to be an overall reduction in vulnerabilities.

Rather than tackling security after software has been developed, your platform should be secure right from the start.

And this creates a virtuous cycle by eliminating a lot of the stress during development, minimising the impact of glitches, ensuring a safer user experience, and so on.

Improved Communication

As we mentioned earlier, collaboration is a huge part of this methodology. When everyone is responsible for security, it tends to create an atmosphere where various team members across different departments communicate with one another openly.

This means you’re less likely to find a person thinking, “It’s okay, someone else will take care of it.” Instead, everyone is working hand in hand to amplify security.

DevSecOps – Improved Communication

There’s an element of transparency there that may not have existed otherwise. In turn, this helps keep everyone on the same page and prevents a clog from forming in the communication pipeline.

What’s interesting is that this can often have a positive impact on the macro level. By implementing DevSecOps, its common to find that the improved communication rubs off on a company’s culture where transparency becomes the norm.

And this can have a tremendous impact.

Make Fixes Quickly

Time is of the essence when it comes to cybersecurity. DevSecOps puts your organisation in a position where you can swiftly respond to vulnerabilities and fix them quickly.

Rather than letting something fester and jeopardize the overall quality of your end product, you can take care of it and keep moving forward.

Not only is this important for staying one step ahead of cyber criminals. This ultimately allows you to expedite your time-to-market and puts your software in the hands of users in less time—something that’s very important in hyper-competitive industries.

Ensure Compliance

There are several security-based regulations in place mandating that organisations meet certain standards. As you’re probably aware, failure to comply can have some very unsavoury consequences primarily in the form of penalties.

But this approach naturally lends itself to compliance regardless of what the specific regulation may be. On top of that, you’ll be better prepared whenever those regulations inevitably change and new requirements are added.

A Better Reputation

Consumers are more aware of cybersecurity than ever. With the number of incidents on the rise, people want to be sure that the companies they do business with are taking security seriously. They want to know that they’re in good hands when using their software.

Jason Hart of CSO puts things into perspective by saying:

  1. 67 percent of consumers fear that they will fall victim to a data breach in the future
  2. 62 percent believe that companies are primarily responsible for the security of their information
  3. 93 percent say they would take or consider taking legal action against an enterprise that has been breached

So it’s reasonable to assume that the proactive nature of DevSecOps where you actively hunt down threats will be appealing to most consumers. They know that you’re doing everything within your power to ensure their digital safety.

Not only can this help you avoid poor publicity, it can often be the catalyst for a boost in brand equity and give your company an edge over the competition.

Increased Revenue

When consumers aren’t worried about the safety of your product, it often translates into more sales. Just put yourself in your average customer’s shoes for a second.

Would you feel more comfortable doing business with a company that uses advanced security tactics or one that’s lax about security and takes a reactive approach?

Of course it would be the former. We live in a day and age where cyber attacks are all over the news, which has created somewhat of a paranoia for many people.

As a result, many are only willing to do business with brands with beefy security measures. And besides the increase in immediate sales, this can potentially contribute to the longevity of your company as well.


With immense benefits like these, you’re likely interested in learning more about how you can actually implement DevSecOps into your organisation. One of the best ways to get started is to actively adopt these principles so that your collective mindset aligns with the DevSecOps manifesto.

It’s unrealistic to expect a complete transformation overnight. But making gradual changes and taking it step-by-step should allow you to eventually adopt this type of framework.

A New Standard of Security

At the end of the day, DevSecOps is about one main thing—bridging the gap between development and security.

DevSecOps -A New Standard of Security

It’s what allows dev teams to build and launch software within a short timeframe, while still addressing security concerns. This way you’re able to deliver a quality product that’s airtight from a security standpoint.

And with software development evolving at an increasingly rapid rate, it’s likely that this methodology will only continue to grow in importance.
