What is Shift Left Security & Testing?

As organizations race against time to deliver cutting-edge products and services, the traditional approach of addressing security and testing as mere checkpoints in the development lifecycle is becoming obsolete. Here comes the “Shift Left” mindset—a paradigm shift that not only challenges conventional timelines but fundamentally alters the way we perceive and implement security and testing in the software development life cycle.

Usually, in traditional SDLC, security and testing were relegated to the final stages of development. However, the landscape is evolving, pushing organizations to adopt a more proactive approach by integrating security and testing considerations from the project’s inception.

For instance, instead of fixing issues much later in the process, what if we spot and tackle them right from the start?  “Shift Left” proposes just that – a scenario where security and testing aren’t just late-stage guardians but integral allies right from the project’s initiation.

This blog is your guide to the intricacies of shift left security and testing. We’ll dissect the nuances, highlight the advantages, and provide insights into the transformative potential of this innovative approach. 

What Is Shift Left DevOps?

When it comes to DevOps, “shift left” is all about ensuring that application security takes the spotlight right from the get-go in the development lifecycle. Why the name “Shift Left”? Assume the traditional timeline of the software development lifecycle as a straight line. Shifting left means we’re moving some crucial processes—specifically security and testing—closer to the beginning of that line. 

Why does it matter? Well, when we talk about “Shift Left DevOps,” we’re essentially talking about a proactive stance. Instead of dealing with security concerns and testing hiccups later down the line, we’re tackling them head-on right from the inception of a project. 

So, implementing shift left security in DevOps is like bringing the A-team—developers, automation and operations experts—into the picture early on.

What is Shift Left Security?

Traditionally, security testing used to be the latecomer to the development party, usually scheduled at the end of the cycle, post-application testing. Picture security teams stepping in at the eleventh hour, performing analyses like static analysis (SAST) and dynamic analysis (DAST).

The outcome of this late-stage scrutiny determined whether an application was greenlit for deployment or sent back to the drawing board for developers to patch up. However, this process came with its set of challenges, often resulting in prolonged development timelines or, worse yet, the release of software into production without robust security measures. 

This is where “Shift Left Security” comes into play. This game-changing approach flips the script by incorporating security measures throughout the entire development lifecycle rather than relegating them to the tail end. The mission? To infuse security best practices into the software design itself and catch potential security issues and vulnerabilities as early as possible in the development process.
