In information security, “shift left” refers to the idea of moving security controls and processes closer to the point of development, in order to catch issues and vulnerabilities earlier in the software development lifecycle (SDLC). The rationale behind the shift left approach is that it is cheaper and easier to fix vulnerabilities and security issues earlier in the SDLC than it is to find and fix them after the software has been released.

There are a number of different ways to shift security left, but the most common approach is to embed security controls and processes into the software development process itself. This can be done in a number of ways, including:
-Using security tools and frameworks that are specifically designed for the SDLC, such as the OWASP Top 10 or the SANS 25
-Integrating security into the code review process
-Performing security testing as part of the build and deployment process
-Creating security-focused development guidelines and best practices
-Training developers on how to write secure code
-Establishing a security culture within the organization
The benefits of shifting security left are many. By embedding security into the SDLC, organizations can catch and fix vulnerabilities and security issues earlier, before they can cause damage. This can not only reduce the number of security incidents, but it can also help to improve the overall quality of the software. In addition, it can help to improve communication and collaboration between developers and security professionals, and it can make the development process more secure and efficient.
Where DevOp Fits In
DevOps is a cultural and technical movement that encourages collaboration between software developers and other IT professionals while automating the software delivery process. The goal of DevOps is to improve the flow of work between development and operations while automating the process of software delivery and infrastructure changes. DevOps is not a specific tool, but rather a collection of practices that help organizations improve the speed and quality of software delivery.
One of the main goals of DevOps is to shift security left, that is, to integrate security into the development process as early as possible. Security should not be an afterthought, but rather an integral part of the development process. Security cannot be bolted on at the end of the process, it must be integrated into the process from the beginning.
There are several reasons why security should be shifted left in DevOps. First, security is a critical part of any software application. Security needs to be integrated into the development process to ensure that applications are secure from the beginning. Second, security is a constantly evolving process. New threats are constantly emerging and security needs to be updated to address these new threats. Third, security is a complex process. It can be difficult to integrate security into the development process without disrupting the flow of work. Fourth, security is often viewed as a roadblock to rapid software delivery. Security can slow down the process of software delivery and can interfere with the flow of work. The goal of DevOps is to remove these roadblocks and to speed up the process of software delivery.
