Our first post in the series introduced the concept of federated learning and described how it’s different from traditional centralized learning – in federated learning, the data is distributed among participating organizations, and share model updates (instead of raw data).

What kinds of techniques can we use to build privacy-preserving federated learning systems? It turns out to depend heavily on how the data is distributed. This post defines and explains the different ways data can be distributed, or partitioned, among participants in federated learning systems. Future posts in the series will describe specific techniques applicable in each situation.

Data partitioning schemes describe how data is distributed among participating organizations, as compared to the centralized scheme in which one party holds all the data.

• In a horizontal partitioning scheme, the rows of the data are distributed among the participants.
• In a vertical partitioning scheme, the columns of the data are distributed among the participants. 

Combinations of the two are also possible—we’ll get to those at the end of this post…

The initial public draft of NIST Internal Report (IR) 8504, Access Control on NoSQL Databases, is now available for public comment. NoSQL (i.e., “not only SQL” or “non-SQL”) database systems and data stores often outperform traditional relational database management systems (RDBMSs) in various aspects, such as data analysis efficiency, system performance, ease of deployment, flexibility/scalability of data management, and users’ availability. However, with an increasing number of people storing sensitive data in NoSQL databases, access control issues have become a fundamental data protection requirement for database management systems.

This document discusses access control on NoSQL database systems by illustrating the NoSQL database types and their support for access control models. It operates under the assumption that the access control system stores and manages access control data (e.g., subjects, objects, and attributes) in the NoSQL database and describes considerations from the perspective of access control in general.

A public comment period is open through March 15, 2024. See the publication details for a copy of the draft and instructions for submitting comments.

NOTE: A call for patent claims is included on page ii of this draft. For additional information, see the Information Technology Laboratory (ITL) Patent Policy – Inclusion of Patents in ITL Publications.

Companies in major industries such as finance and health care must follow best practices for monitoring incoming data for cyberattacks. The latest internet security protocol, known as TLS 1.3, provides state-of-the-art protection, but complicates the performance of these required data audits. The National Institute of Standards and Technology (NIST) has released a practice guide describing methods that are intended to help these industries implement TLS 1.3 and accomplish the required network monitoring and auditing in a safe, secure and effective fashion.

The new draft practice guide, Addressing Visibility Challenges with TLS 1.3 within the Enterprise (NIST Special Publication (SP) 1800-37), was developed over the past several years at the NIST National Cybersecurity Center of Excellence (NCCoE) with the extensive involvement of technology vendors, industry organizations and other stakeholders who participate in the Internet Engineering Task Force (IETF). The guidance offers technical methods to help businesses comply with the most up-to-date ways of securing data that travels over the public internet to their internal servers, while simultaneously adhering to financial industry and other regulations that require continuous monitoring and auditing of this data for evidence of malware and other cyberattacks.

A Chinese-state-backed hacking group is targeting legacy devices, primarily Cisco routers, to expand its attack infrastructure in a new campaign that marks a notable strategic shift in its threat activity. Volt Typhoon, an emerging advanced persistent threat (APT) group identified last year, is exploiting two known vulnerabilities, CVE-2019-1653 and CVE-2019-1652, to compromise Cisco RV320/325 routers that were discontinued in 2019. Neither vulnerability has a patch available. In its latest campaign, the threat group is leveraging a botnet  of compromised small office/home office (SOHO) devices linked to previous attacks attributed to Volt Typhoon. Notably, Volt Typhoon’s botnet infrastructure communicated with 27 IP addresses that host 69 sites belonging to government entities in the United States, the United Kingdom, and Australia.

New Indicators of Compromise (IOCs) and Shifting Tactics

SecurityScorecard’s STRIKE team released a report detailing their research into the group’s latest campaign after discovering that the group compromised approximately 30 percent of the Cisco RV320-325 routers observed by the team over a 37-day period. Of the 1,116 target devices analyzed, the team identified 325 devices communicating with two IP addresses of known proxies used by Volt Typhoon actors. The threat group is also deploying a custom web shell to maintain access to the compromised devices, which can be identified by the filename “fy.sh.”

Additionally, the STRIKE team uncovered multiple new IP addresses linked to their activity, providing further evidence of the threat group’s intent to develop new attack infrastructure:

45.63.60[.]39 45.32.174[.]131 82.117.159[.]158 46.10.197[.]206 176.102.35[.]175 93.62.0[.]77 194.50.159[.]3 80.64.80[.]169 24.212.225[.]54 208.97.106[.]10 70.60.30[.]222 184.67.141[.]110 89.203.140[.] 246 94.125.218[.]19 183.82.110[.]178 117.239.157[.]74 210.212.224[.]124 49.204.75[.]92 61.2.141[.]161 49.204.75[.]90 114.143.222[.]242 117.211.166[.]22 49.204.65[.]90 49.204.73[.]250

While Volt Typhoon continues to target SOHO devices, which are better for concealing malicious traffic, the group has shifted towards targeting legacy systems. The targeted Cisco routers are currently impacted by 35 vulnerabilities that may be left unaddressed. This tactic represents a significant shift, as focusing on end-of-life devices requires knowledge of older systems and associated vulnerabilities, which may not be widely known.
