NIST proposes a Secure Software Development Framework to address software supply chain attacks
Applying software updates and patches as soon as possible is a cybersecurity best practice, but what if an update contains malicious code inserted by a hacker? Software supply chain attacks are a serious and growing problem for both private-sector organizations and the federal government. Among other incidents, Chinese nation-state hackers successfully breached numerous third-party contractors working for the U.S. Navy on multiple occasions over an 18-month period.
The Navy contractor attacks and similar incidents were the impetus for the federal government barring agencies from purchasing certain vendors’ software and hardware. However, these bans don’t address the root of the problem, which is that security must be baked into the software development lifecycle (SDLC) from the very beginning. This is why NIST has proposed a Secure Software Development Framework (NIST SSDF).
What’s in the NIST SSDF?
While there are many SDLC frameworks, few specifically address secure software development; they were designed to speed up and bring order to the development process, not ensure security. Instead, project managers are left to integrate secure development practices on their own.
The proposed NIST SSDF does not introduce any new practices. It curates high-level secure software development best practices from a number of existing sources. So that the framework is flexible, it does not specify how to implement its recommendations. Implementation will look different in every organization, as data environments, security objectives, and priorities greatly differ.
The proposed framework includes 19 best practices for secure software development, grouped under four categories.
Prepare the organization. The best practices in this category are about aligning the organization’s people, processes, and technology to build a strong foundation for secure software development. It outlines practices such as ensuring that security requirements for software development are known at all times so they can be taken into account throughout the SDLC; making sure that everyone involved in the SDLC knows what their roles and responsibilities are regarding secure development; and using automation to improve the accuracy, consistency, and comprehensiveness of security practices.
Protect the software. Software must be secured against tampering and unauthorized access, both intentional and accidental. The best practices in this category address how to secure source code for in-house projects and provide recommendations to aid end users in ensuring that the software they acquire is legitimate and has not been tampered with.
Produce well-secured software. The best practices in this category seek to maximize software security and minimize vulnerabilities in each release. Many developers have not been educated in secure development practices and end up unknowingly producing insecure code. In addition to addressing secure software development practices for in-house projects, it provides recommendations for verifying that third-party software meets security requirements.
Respond to vulnerability reports. This step focuses on identifying potential vulnerabilities in each successive release, addressing them, and preventing similar problems in future releases.
NIST hopes that the recommendations in the SSDF benefit both sellers and buyers in the software supply chain. Sellers who adopt secure software development practices will address the root causes of supply chain cyberattacks by minimizing potential vulnerabilities in each release and mitigating the impact of undiscovered vulnerabilities. Buyers can adapt these practices and incorporate them into their software acquisition processes.
The public comment period for the draft NIST SSDF began on June 11 and ends on August 5, 2019.

What Is Autonomous Malware?
We’re reaching the end of 2025, and looking ahead to 2026, most experts are discussing the latest threats that will shape the year ahead. This year, we’re seeing a new, but not unexpected, shift to autonomous threats driven by state-sponsored actors and AI. With that in mind, a new generation of threats, broadly known as...Continue reading→
What CISA’s Emergency Directive 26-01 Means for Everyone
In mid-October 2025, the CISA issued one of its most urgent orders yet: Emergency Directive 26-01. The directive calls on all Federal Civilian Executive Branch (FCEB) agencies to immediately mitigate vulnerabilities in devices from F5 Networks following a state-sponsored breach of F5’s systems and access to portions of BIG-IP source code and vulnerability data. The event...Continue reading→
Cybersecurity and Vetting AI-Powered Tools
A recent exploit involving a new AI-focused browser shone a light on a critical problem–namely, that browser security is a constant issue, and AI is just making that threat more pronounced. Attackers discovered a way to use that browser’s memory features to implant hidden instructions inside an AI assistant. Once stored, those instructions triggered unwanted...Continue reading→
Shutdown Security And Cyber Vulnerability
When the federal government shuts down, the public sees closed monuments, unpaid workers, and halted programs. What they do not see is the silent surge of cyberattacks targeting agencies already operating on fumes. During the most recent shutdown, attacks against U.S. government systems spiked by nearly 85%. Cybersecurity failures during government disruptions rarely start with...Continue reading→
Identity and the Shift from Malware
The world of cyber threats is rapidly evolving, and while we can see these changes more generally, it’s always crucial to understand them concretely. As the 2025 CrowdStrike Global Threat Report shows us, the landscape of our industry is changing. We’re digging into this report to discuss a challenging trend: the move of hackers foregoing...Continue reading→
Maintaining Compliance Against Prompt Injection Attacks
The increasing adoption of AI by businesses introduces security risks that current cybersecurity frameworks are not prepared to address. A particularly complex emerging threat is prompt injection attacks. These attacks manipulate the integrity of large language models and other AI systems, potentially compromising security protocols and legal compliance. Organizations adopting AI must have a plan...Continue reading→
Are We Already Talking About CMMC 3.0?
The ink has barely dried on the CMMC final rule, and already the defense contracting community is buzzing with speculation about what comes next. Just when contractors thought they had a moment to catch their breath after years of regulatory limbo, whispers of CMMC 3.0 have begun circulating through the industry. But is this just...Continue reading→
Centralizing Identity-Based Risk
As the traditional network boundary dissolves and remote work becomes standard practice, identities are the major frontier for security. Whether we’re talking about human users, service accounts, or machine identities, these have emerged as both the primary access mechanism and the most targeted attack vector. It has become imperative for providers to centralize identity management...Continue reading→
