The National Security Agency (NSA), Cybersecurity and Infrastructure Security Agency (CISA), and the Office of the Director of National Intelligence (ODNI) have published a set of DevSecOps best practices based on the Enduring Security Framework (ESF).
Developed by a public-private cross-sector working group led by NSA and CISA, the ESF framework was created in the wake of the breach of the SolarWinds software supply chain that led to malware being distributed downstream to a number of organizations that relied on the company’s IT management platform.
The Securing the Software Supply Chain for Developers set of best practices published by NSA, CISA and ODNI takes the ESF a step further. The guidance walks organizations through the processes required to develop secure code, verify third-party components, harden build environments and deliver code.
The best practices provided are the latest dividend of an executive order issued by the Biden administration that requires every federal agency to review the security of its software supply chains. The expectation is that enterprise IT organizations will conduct similar reviews using the best practices and frameworks defined by the federal agencies that specialize in cybersecurity.
The challenge, of course, is embedding those best practices within existing DevOps workflows. In theory, more responsibility for cybersecurity is shifting left toward application development teams. However, the level of cybersecurity expertise that exists today among application developers is limited at best. Cybersecurity was an elective in most developers’ training and education programs, so it should come as no surprise that few of them ever attended a cybersecurity class.
There’s a clear need to improve cybersecurity training for developers, but the real work involves automating cybersecurity processes within the workflows managed by the tools developers employ to write code and the platforms that DevOps teams use to deploy applications, said Mitch Ashley, principal analyst for Techstrong Research, an arm of Techstrong Group that is also the parent company of DevOps.com. “Security needs to be part of the toolchain, workflows and how the software is designed,” he said.
Ideally, organizations should appoint a security champion that will work with development teams to consistently implement a set of DevSecOps best practices, added Ashley.
Of course, the security champion doesn’t eliminate the need for cybersecurity professionals. Rather, it reduces the pressure when there is a chronic shortage of cybersecurity professionals. In the absence of any formal cybersecurity review during the application development process, it’s simply too easy for developers to inadvertently introduce malware into a software component or misconfigure a cloud infrastructure service. In either case, cybercriminals are increasingly finding it easier to compromise software supply chains at multiple points.
It’s not clear how much the federal government’s guidance might impact the overall state of application security. However, one way or another the level of security scrutiny being applied to how applications are built and delivered is only going to increase in the months ahead. The challenge is finding a way to deliver secure code without necessarily slowing down the rate at which applications are currently being built and deployed.
