Mitigate Baron SameEdit (CVE-2021-3156) vulnerability

DevSecOps for your full stack

By Ronald Nixon

If you’re in the business of securing government systems against hackers looking to exploit financial data, employee records or secure transactions, you know it’s an ever-increasing challenge to keep your systems safe. Unfortunately, traditional approaches that address just one or two segments of your DevOps cycle just aren’t cutting it any more, leaving you vulnerable.

To protect against old, new and future attacks by bad actors, you need to build security into every aspect of your software development workflow and system stack. This approach transforms DevOps into DevSecOps, addressing everything from your infrastructure and platform, your CI/CD workflows, the service layer where firewalls and security rules live, and the application layer where customer interaction happens. 

However, hardening all levels of your stack can add complexity, disrupt your workflows and require you to scrap your existing tooling. None of that is practical, but it leaves you with a conundrum: You can neither afford to start from scratch nor maintain time-consuming manual or outdated security practices that sap even the best DevSecOps teams.

Prevent attacks by applying a broader approach

Vulnerability begins at the base of your stack — the infrastructure and OS layer — which is often made up of cloned virtual machines or cloud instances. If bad actors can gain access to one system, chances are good they can access all its clones. That means your entire fleet can be compromised by common security flaws they share.

To prevent that, large fleet owners need to diversify their systems in ways that are secure, repeatable and fast. It’s a complex task, and doing it manually just isn’t feasible.

At the CI/CD layer of your stack, your principle worry is the risk of bad actors injecting malicious code into your build process. This could be hard to spot and prevent, requiring complex security countermeasures and code analysis. You need to be able to quickly identify anomalies and act to prevent bad code from making it into production, and manual solutions are prohibitively time-consuming.

Shifting to the cloud doesn’t eliminate your risks

Offloading applications to the cloud doesn’t make any of this less important. If your AWS, Azure, Google or other cloud service instances are identical, so are your vulnerabilities. Deploying code to a cloud service also won’t make your CI/CD workflows tamper-resistant. You still need your code to be authenticated and trusted, regardless of whether the final destination is the cloud or your own data center.

Ideally, you need a solution tuned to a hybrid cloud environment, one that works well with legacy on-prem systems, cloud-based apps and everything in between. Without that, you’re faced with having to create different versions of your DevSecOps hardening for each environment. That’s hard to maintain and can leave you with a patchwork of compromised systems. Again, that’s a maintenance nightmare that’s certain to keep you up at night. 

Visibility and speed are critical, too

If you’ve developed tooling to cover each layer of your DevSecOps stack, you probably recognize that your work isn’t done until your solution enables you to see vulnerabilities in real-time and doesn’t bog down your release schedule. Having the ability to quickly see, manage and control your systems — while building and deploying custom packages as needed — is as important as the security measures themselves.  

At Polyverse, we understand your pain. Our new Polymorphic Build Farm for Open Source white paper explains how we can help solve these problems in ways that significantly reduce your system vulnerabilities and don’t require you to give up the tools you know and love.
