In May 2020, NIST published Foundational Cybersecurity Activities for IoT Device Manufacturers (NIST IR 8259), which describes recommended cybersecurity activities that manufacturers should consider performing before their IoT devices are sold to customers. These foundational cybersecurity activities can help manufacturers lessen the cybersecurity-related efforts needed by customers, which in turn can reduce the prevalence and severity of IoT device compromises and the attacks performed using compromised devices. In the nearly five years since this document was released, it has been published

Cybersecurity is a fast-growing field, with a constant need for skilled professionals. But unlike other professions — like medicine or aviation — there’s no clear-cut pathway to qualifying for cybersecurity positions. For employers and job seekers alike, this can make the journey to building a team (or entering a successful cybersecurity career) feel uncertain. Enter the registered apprenticeship program — a proven method for developing skilled talent in cybersecurity that benefits both the employer and the new professional. Let’s commit to supporting this important talent development approach

If you are interested in the world of digital identities, you have probably heard some of the buzzwords that have been floating around for a few years now… “verifiable credential,” “digital wallet,” “mobile driver’s license” or “mDL.” These terms, among others, all reference a growing ecosystem around what we are calling “verifiable digital credentials.” But what exactly is a verifiable digital credential? Take any physical credential you use in everyday life – your driver’s license, your medical insurance card, a certification or diploma – and turn it into a digital format stored on your

The rapid proliferation of Artificial Intelligence (AI) promises significant value for industry, consumers, and broader society, but as with many technologies, new risks from these advancements in AI must be managed to realize it’s full potential. The NIST AI Risk Management Framework (AI RMF) was developed to manage the benefits and risks to individuals, organizations, and society associated with AI and covers a wide range of risk ranging from safety to lack of transparency and accountability. For those of us at NIST working in cybersecurity, privacy and AI, a key concern is how advancements

Human-centered cybersecurity (also known as ‘usable security’) involves the social, organizational, and technological influences on people’s understanding of and interactions with cybersecurity. By taking a human-centered cybersecurity (HCC) approach, we can both improve people’s cybersecurity experiences and achieve better cybersecurity outcomes, which is so important in today’s digitally interconnected world. At NIST, we understand the value of making connections, listening, and interactivity. We also understand that researchers and practitioners want to hear directly from each other—and

In this post, we talk with Dr. Xiaowei Huang and Dr. Yi Dong (University of Liverpool), Dr. Mat Weldon ( United Kingdom (UK) Office of National Statistics (ONS)), and Dr. Michael Fenton (Trūata) who were winners in the UK-US Privacy-Enhancing Technologies ( PETs) Prize Challenges. We discuss implementation challenges of privacy-preserving federated learning (PPFL) – specifically, the areas of threat modeling and real world deployments.

The last few months have brought even more opportunities for NIST to engage with our international partners to enhance cybersecurity. Here are some updates on our recent international engagement: Conversations have continued with our partners throughout the world on the recent release of the Cybersecurity Framework Version 2.0 . NIST international engagement continues through our support to the Department of State and the International Trade Administration (ITA) during numerous international dialogues. Most recently, NIST participated in interagency dialogues to share information on NIST

Can you recall the last time you opened a bank account? It’s likely you walked into a local bank branch and spoke to a representative who asked for your driver’s license and social security card to verify your identity. Now imagine you want to create a bank account online. The process is likely similar—type in your social security number, take a picture of your driver’s license, and submit both to the bank via their webpage. Seems straightforward, right? Identity verification is important—it protects us from identity theft and reduces the risk of fraud and unauthorized access for organizations

I joined NIST as the first full-time manager of the NICE Framework in October 2020, just one short month before NICE published the first revision NIST Special Publication 800-181, the NICE Workforce Framework for Cybersecurity (NICE Framework). That revision – far from finalizing work – was the starting point that led us to a complete refresh of the NICE Framework components, which includes: Revised Work Role Categories and Work Roles – including one new Work Role. Eleven new Competency Areas that extend the Framework’s cybersecurity knowledge and skills. Updated Task, Knowledge, and Skill

The problem The previous post in our series discussed techniques for providing input privacy in PPFL systems where data is horizontally partitioned. This blog will focus on techniques for providing input privacy when data is vertically partitioned . As described in our third post , vertical partitioning is where the training data is divided across parties such that each party holds different columns of the data. In contrast to horizontally partitioned data, training a model on vertically partitioned data is more challenging as it is generally not possible to train separate models on different

The U.S. Small Business Administration is celebrating National Small Business Week from April 28 – May 4, 2024. This week recognizes and celebrates the small business community’s significant contributions to the nation. Organizations across the country participate by hosting in-person and virtual events, recognizing small business leaders and change-makers, and highlighting resources that help the small business community more easily and efficiently start and scale their businesses. To add to the festivities, this NIST Cybersecurity Insights blog showcases the NIST Cybersecurity Framework 2.0

We all need supplements sometimes. Whether it’s a little extra vitamin C during flu season or some vitamin D during the dark days of Winter. When used correctly, supplements help our body adjust to the changing conditions around us. Similarly, we are applying this same concept for the first time to our NIST SP 800-63B, Digital Identity Guidelines: Authentication and Lifecycle Management. Today, we published a supplement that provides interim guidance for agencies seeking to make use of ‘syncable authenticators’ ( for example, passkeys) in both enterprise-facing and public-facing use cases

In our second post we described attacks on models and the concepts of input privacy and output privacy. ln our last post, we described horizontal and vertical partitioning of data in privacy-preserving federated learning (PPFL) systems. In this post, we explore the problem of providing input privacy in PPFL systems for the horizontally-partitioned setting. Models, training, and aggregation To explore techniques for input privacy in PPFL, we first have to be more precise about the training process. In horizontally-partitioned federated learning, a common approach is to ask each participant to

Last November, I was pleased to chair the most recent meeting of the Interagency International Cybersecurity Standardization Working Group (IICSWG) – a group NIST created in 2016. Our charge, from the Cybersecurity Enhancement Act of 2014, was to build a coordination mechanism for government agencies to discuss international cybersecurity standardization issues, consistent with agencies’ responsibilities under OMB Circular A-119. Since then, IICSWG has grown as a forum to discuss cybersecurity and privacy standardization topics, examine the overall cybersecurity standardization landscape (

It’s been four years since the release of The NIST Privacy Framework: A Tool for Improving Privacy Through Enterprise Risk Management, Version 1.0. Since then, many organizations have found it highly valuable for building or improving their privacy programs. We’ve also been able to add a variety of resources to support its implementation. We’re proud of how much has been accomplished in just a few short years, but we’re not resting on our laurels. As another, more famous, Dylan once said, “the times they are a-changin’.” For example, the past year has seen the release of the NIST AI Risk

Learn more and read all the posts published to date at NIST’s Privacy Engineering Collaboration Space or the CDEI blog . Our first post in the series introduced the concept of federated learning—an approach for training AI models on distributed data by sharing model updates instead of training data. At first glance, federated learning seems to be a perfect fit for privacy since it completely avoids sharing data

Words like “metaverse” and “augmented reality” may conjure up thoughts of friends in headsets wielding virtual sabers or folks roaming the streets at night in search of PokéStops. Virtual, augmented, and mixed reality technologies (“immersive technologies”) have entered the popular conscience thanks in part to the success of games, but their applications go well beyond new experiences in entertainment. They are already being utilized to increase access to education , improve manufacturing , bolster accessibility , and train workforces in healthcare and retail. Immersive technologies have the

In August 2023 the Digital Identity Guidelines team hosted a two-day workshop to provide a public update on the status of revision 4. As part of that session, we committed to providing further information on the status of each volume going forward. In fulfillment of this commitment, we wanted to offer a quick update on where we stand. Our goal remains to have the next version of each volume out by the Spring of 2024. With our gratitude for the robust and substantive engagement we received during the comment period, at this time we would like to announce that all four volumes of Special

5G will eventually impact every single industry—from healthcare to financial to even agriculture and transportation…and its impact is only increasing over time. Despite its benefits, it comes with privacy and security risks. An increasing number of interconnected devices increases the attack surface. In addition, there are also increased supply chain vulnerabilities and network visibility issues (companies may have issues identifying attacks since there may be a lot of new web traffic from mobile devices and/or more sophistication when it comes to attacks). The goal of the NCCoE 5G

Our Cybersecurity Awareness Month may have come to a close at the end of October — but the importance of enhancing cybersecurity and engaging with our international partners to enhance cybersecurity is at the forefront of our minds all year long.
