Digital transformation is driving change in every corner of the security industry. Organizations are evolving and expanding into the cloud rapidly, but their security teams and legacy data centers are holding them back. A skills and resources gap exists industrywide, but implementing a DevSecOps approach is key toward bridging that gap.
DevSecOps, an inherently agile and nimble approach to security, is well suited for a more cloud-enabled future. Bringing together formerly isolated teams under one function allows security to be built in throughout the development process, also known as security by design, meaning that security can be more than an afterthought at the beginning and the end.
But DevSecOps only works if organizations are willing to give their teams the resources and tools to successfully bridge those skill and resource gaps. Before you change your direction, you first need to address the issues with your current posture, understand the capacity of your current security teams, and find a guiding principle to drive your development. Here's where to start.
New Solution, Same Old Mistakes
Faced with the evolving threats brought on by digital transformation, organizations need to be aware of their existing postures and shortcomings in protecting their data.
This means asking questions about how you can improve your security posture in the cloud and rethink your best practices, finding the elements that are most germane to your organization. Instead of using the monolithic code that lived inside your data center, you have to architect your infrastructure from the beginning to continuously monitor based around these principles.
Because of digital transformation, your security posture will change and your best practices will need to be tweaked. Having a DevOps team that is questioning the past, and improving your security posture throughout this iterative transformation will pay off as your organization continues to scale.
Cloud-enabled security is meant to be iterative. It's a foregone conclusion that you're going to have incidents, but a DevSecOps team that is constantly iterating can catch them faster and fix issues as they come up. The security exists throughout the process, not just at the endpoints. This is the goal.
After solving this problem, you then need to make sure you have the right team for the job.
Mind the Skills Gap
I've talked with many organizations that tell me they've been doing DevOps for a long time, but that's often not entirely true. Sure, they have people monitoring their data centers, making sure the lights on the boxes are still blinking, but they aren't actually digitally transforming that team. As security moves into the cloud, that team is going to be responsible for rebuilding that infrastructure in the cloud, and if security isn't a part of the conversations around this infrastructure, organizations are missing a huge opportunity.
When organizations decide they want to do DevSecOps, they turn to a team, be it development, operations, or security, and tell them they need to get on board with transforming, often without the proper skills, resources, or guidelines. You need to know your DevOps teams' comfort level with security, and around digital transformation. For example, if they don't know about serverless infrastructure, beyond the obvious, then you're in for trouble.
Expecting a team to exclusively learn on the fly is basing a strategy on hope, which is always doomed to fail. Instead, take your spare moments and offer your DevSecOps team opportunities to learn from their blind spots, whether with additional certifications or shadowing. It doesn't have to be perfect, but every bit helps. This way, they are constantly getting better and modernizing, improving themselves as they improve your security infrastructure.
Find the North Star
DevSecOps can only help solve for issues if you have a guiding principle, or north star, for what you're trying to accomplish. Doing this means making sure you know how you're implementing and improving your security posture in the cloud.
It's important to factor in security as you go, and embody visibility and contextual application of controls. For a long time, security teams pushed for access within the enterprise perimeter, but the transition to cloud computing is making all of that access obsolete, clouding their visibility and the effectiveness of how perceived controls will work in the cloud.
DevSecOps is all about consolidating teams to pool resources, better leverage skills, and realize unified goals and perspectives, which are key. And as I noted earlier, this doesn't have to be perfect. Success with DevSecOps comes with being cloud curious and learning what matters most to your organization. This is an opportunity to take a modernized security stack to the cloud, in addition to business innovation. It's a fresh start to security, forecasting increased visibility and contextual controls applied at scale, all while supporting the agility of the business, all of which makes for a well-defined transformation. The lessons learned are:
You're going to have bumps along the way, and have to iterate, but each iteration will make your DevSecOps team learn and better prepared for whatever the next threat presents.
