Read MoreI 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…

Read MoreVirtual private networking (VPN) companies market their services as a way to prevent anyone from snooping on your Internet usage. But new research suggests this is a dangerous assumption when connecting to a VPN via an untrusted network, because attackers on the same network could force a target’s traffic off of the protection provided by their VPN without triggering any alerts to the user.

Read MoreToday, CISA and the Federal Bureau of Investigation (FBI) released a joint Secure by Design Alert, Eliminating Directory Traversal Vulnerabilities in Software. This Alert was crafted in response to recent well-publicized threat actor campaigns that exploited directory traversal vulnerabilities in software (e.g., CVE-2024-1708, CVE-2024-20345) to compromise users of the software—impacting critical infrastructure sectors, including the Healthcare and Public Health Sector. Additionally, this Alert highlights the prevalence, and continued threat actor exploitation of, directory traversal defects. Currently,…
Read MoreThe 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…
Read MoreToday, CISA, in collaboration with U.S. and international partners, published a joint fact sheet, Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity. This fact sheet provides information and mitigations associated with cyber operations conducted by pro-Russia hacktivists who seek to compromise industrial control systems (ICS) and small-scale operational technology (OT) systems in North American and European critical infrastructure sectors, including Water and Wastewater Systems, Dams, Energy, and Food and Agriculture Sectors. The pro-Russia hacktivist activity…
