![]() ![]() Every step of the software development process is an opportunity to give feedback and look for security issues. This must change, and the work done in the previous steps will arm you to do this. However, software quality has not historically included security. Quality assurance has always been part of the software development lifecycle. Step 3: Identify and implement security quality guardrails Undoubtedly, much of your software development is being done in the public cloud. This may also be referred to as the CI/CD toolchain. Key items to identify in this phase include who is developing code (people), how it flows from development laptops to production (process), and which systems they are using to enable the process (technology). It is highly likely that each business unit will have its own software development process and tools. Medium to large organizations will want to start at the macro level and then drill into individual business units. The goal of this step is to first look organization-wide and document the overall flow of software in your company. Small and medium-sized organizations will find this step relatively straightforward but equally rewarding. Oftentimes, development is outsourced to multiple vendors, which will require additional work and sometimes contract reviews. Large organizations that have not undertaken this process will likely spend a few months digging and taking development teams out to lunch (food always seems to work) when geography permits. This step is significant because the end result is what allows the security team to understand where they can actually move security closer to development. Depending on the size of your company, this could run the gamut from straightforward to extremely challenging. Perhaps one of the most challenging aspects of shifting security left is first getting a handle on how and where software is created in your organization. Step 2: Understand where and how software is created in your organization ![]() Expect the strategy document to mature over time and don’t spend too much time trying to perfect it. Key items to include in this document are vision, ownership/responsibility, milestones, and metrics. This is about painting the most vivid picture possible for your teams so they know what success looks like. It is critical to define what shift-left means in your organization. Do not underestimate the power of a concisely (ideally one-page) written strategy document. The first step of any journey is to define where you intend to go. Step 1: Define your shift-left security strategy The same study also found that addressing security issues during testing could be 15 times costlier.īeing intentional about embedding security in each of these steps starts with a clearly defined strategy. The System Sciences Institute at IBM found that addressing security issues in design was six times cheaper than during implementation. Consider that shift-left security is good for reducing not only cyber risk but also cost. Many security teams only become involved in the concluding steps of operations and monitoring. Modern CI/CD typically involves an eight-step process as shown in Figure 1 below. In its most simple terms, “shift left” security is moving security to the earliest possible point in the development process. The best way to get this done is to implement a shift-left security strategy. Given this radical shift in attacker focus, it’s time to embed security with development. Consider that over the past five years, out of all published vulnerabilities, 76% were from applications. Recent vulnerability research confirms this. Since the beginning of modern computing, security has largely been divorced from software development. 简体中文 (Chinese (Simplified) ) 繁體中文 (Chinese (Traditional) ) 日本語 (Japanese ) 한국어 (Korean ) Português (Portuguese (Brazil) )
