In the ever-evolving world of DevOps, two concepts, Shift Left and Secure Right, surfaced as catch-phrases that signal a shared desire to develop more secure and reliable software.
Yet a common misunderstanding prevails, particularly from a security standpoint, surrounding what these concepts truly entail. All too often, organizations unintentionally burden development teams with additional work in pursuit of these shifts, essentially undermining the fundamental principle of DevOps: shared responsibility.
At the core of the DevOps mindset lies the belief that development and IT operations teams share joint accountability for the success of building and deploying software. Enter DevSecOps, an extension of this collaboration that introduces security in the form of an application security (AppSec) team.
Regardless of if you adopt Shift Left or Secure Right in DevOps or DevSecOps, neither shift should involve one team simply passing security tasks to another. Both aim to streamline processes and increase communication among teams, but these approaches take divergent routes to achieve these goals.
In this blog post, we explore Shift Left and Secure Right. We aim to shed light on these concepts’ core principles and their pivotal roles in achieving high-quality, secure software delivery. We analyze how Shift Left and Secure Right align with DevOps and DevSecOps, ultimately empowering you to make informed decisions about their integration into your workflows.
To understand the significance of Shift Left and Secure Right, first visualize a software development life cycle (SDLC) in the shape of a continuous loop that can be divided in half.
On the left side, your development team operates in the early phases of the SDLC. They engage in planning, coding, and pre-production testing, all with the goal of crafting software aligned with design specifications. This is the domain of creativity and innovation, where developers bring ideas to life.
On the right side, your IT operations team takes charge of production releases, ensuring software aligns seamlessly with your organization’s business goals and maintains high standards of reliability. This is where software is entrusted to fulfill its intended purpose, maintaining performance and stability.
Allocation of resources and adjustment of priorities to either side of this SDLC loop will yield different outcomes. If you subscribe to the DevSecOps mindset, the positioning of an AppSec team somewhere within or along this loop adds another variable to these considerations.
A decision to shift left or right can empower your development, operations, and security teams to engage proactively in your software’s evolution and ultimately protect against the emergence of functional or security issues in the products you deliver.
Shift Left, a foundational pillar of DevSecOps, prioritizes the integration of testing activities as close to the initial stages of development as possible, seamlessly integrating them into your SDLC.
The core tenets of Shift Left include the following:
When successfully implemented, these Shift Left tenets yield a spectrum of benefits, including:
By embracing Shift Left as a fundamental concept within DevSecOps, organizations can fortify their software development processes, forging a path toward secure and reliable software delivery.
While Shift Left is a cornerstone of DevSecOps, Secure Right, sometimes referred to as Shift Right, stands as a complementary pillar in the broader DevOps mindset and introduces continuous testing of code within a production environment.
Unlike Shift Left, which focuses on early-stage SDLC testing, Secure Right extends the testing phase to post-deployment, aiming to uncover unexpected scenarios that typical production environments might miss.
The core tenets of Secure Right include the following:
Successful implementation of these tenets of Secure Right can bolster security measures, optimize performance, and expedite resolution of post-production issues. Most importantly, Secure Right fosters a culture of continuous learning, driving ongoing software enhancement and innovation.
Within the broader DevOps landscape, Shift Left and Secure Right coexist as complementary strategies, each addressing distinct phases of software development and deployment.
Shift Left focuses on early defect detection, collaboration, and automation, while Secure Right extends testing to post-deployment scenarios to enhance security and performance. Your specific implementation depends on your organization's goals, project requirements, and risk tolerance. Striking a balance between Shift Left and Shift Right can lead to comprehensive software quality, security, and continuous improvement throughout your DevOps journey.
In a world where DevOps is a bridge to agile and efficient software delivery, understanding and acting upon these principles can significantly boost your team's capabilities and elevate the reliability and security of your software applications.
