The security team needs to be able to speak the same language as developers. Your QA personnel don’t need to be elite hackers, but they should have the basic coding skills required to discuss testing processes with developers and ensure that QA work starts early in the delivery chain. You should, however, strive to find and retain people who have the expertise required to collaborate with development and-most importantly-are passionate about such collaboration. This doesn’t mean that everyone on your team needs to be a developer. To shift everything to the left, you need personnel who are prepared to engage with the early parts of the delivery pipeline. You need to reshape the way your entire organization operates, with the goal of integrating all of your processes and personnel into the pre-production stages of the delivery pipeline.Ī successful shift-left culture is one in which the default approach to software production centers on achieving as much as possible before code enters production-because once software is in production, making changes or resolving problems of any kind becomes much more difficult.įollowing are tips for achieving the organizational and cultural transformation required to implement a shift-left culture. These are the types of changes I am referring to when I mention shifting your culture left.Īs noted in the introduction, shifting your entire culture left requires more than just setting up the right processes and tools. Instead, I’d like to discuss the organizational and cultural changes that you need to implement in order to enable shift-left security. Twistlock’s blog already explains the nuts and bolts of shift-left, so I won’t reiterate them here. In other words, the goal is to move processes to the left of the delivery chain. The driving idea is that processes like software testing and security operations should take place early in the software delivery process, rather than waiting until software is in production (or close to it). The shift-left paradigm is relatively straightforward. The Shift-Left Conceptīefore delving into the details of shift-left culture, let’s quickly recap what the shift-left philosophy entails. Intrigued? Keep reading for an explanation of what it takes to shift your culture left in order to improve software security. Ultimately, shifting your culture left involves developing an entirely new paradigm and set of principles for software delivery and security, and using it to replace the philosophy that predominated in the age of waterfall delivery. It also requires designing and enforcing processes that maximize security at all stages of the delivery chain. Shifting your culture left entails choosing the right personnel to ensure that you deliver secure and innovative software. You need to shift your entire culture left. Yet, to make the very most of shift left security, you need to do more than simply integrate security operations with development. Shift left security also helps to optimize the continuous delivery chain by making security part and parcel of the development process. Shift left security practices can significantly reduce the risk of releasing software with security vulnerabilities into production. Much has been made of the concept of “ shift-left security, ” and rightly so.
