Data-driven collaborations often involve sharing large-scale datasets in cloud environments, where adversaries may exploit server vulnerabilities to access sensitive information. Traditional approaches, such as Trusted Execution Environments, lack the scalability for parallel processing, while techniques like homomorphic encryption incur prohibitive computational overheads. ARMOR addresses these limitations by developing encrypted querying techniques that support a variety of scientific data types and queries, balancing efficiency with privacy. The project’s interdisciplinary team focuses on advancing encryption methods, improving query performance for multidimensional data, and rigorously evaluating security risks and overheads under real-world scenarios.

A recent research under ARMOR is the development of Secure Standard Aggregate Queries (SSAQ), a novel approach for secure aggregation on multidimensional sparse datasets stored on untrusted servers. Aggregation functions like SUM, AVG, COUNT, MIN, MAX, and STD are essential for scientific data analysis but pose privacy risks when performed on encrypted data. Existing methods using searchable encryption suffer from access pattern and volume leakage and are often limited to one-dimensional settings. SSAQ overcomes these challenges by employing d-dimensional segment trees to precompute responses for all possible query ranges, thus improving the efficiency of secure range queries.

To further reduce leakage, SSAQ integrates Oblivious RAM (ORAM) to conceal data access patterns during query execution. This combination ensures a higher level of security, making SSAQ suitable for complex scientific data scenarios where sensitive information needs to be safeguarded. The approach significantly extends the applicability of searchable encryption techniques, offering a scalable and efficient solution for secure data analytics in cloud environments while minimizing privacy risks.

Announcing the Publication of v2 of the Trusted CI OT Procurement Matrix & Companion Guide

Last year, the Secure by Design team announced the publication of the first version of the Trusted CI OT (Operational Technology) Procurement Matrix. After gathering feedback from maritime operational technology practitioners and some of their vendors, we have published an updated version of the Matrix and a companion Guide to further assist the OT community.  

The Guide can be found here: https://doi.org/10.5281/zenodo.13743314

The purpose of the Matrix is to assist those in leadership roles during the procurement process. It’s meant to help formulate questions for vendors to discuss security controls on devices that will be used for maritime research. The Matrix includes a list of controls, requirements for the control, potential questions for vendors, tips, and real world examples justifying a given control.    

The updates to v2 of the Matrix includes columns for ISO/IEC 27000 family and the ISA/IEC 62443 Series of Standards.

The updated version of the Matrix can be found here: https://doi.org/10.5281/zenodo.13830599

We have already seen positive impacts from this document. “Even at our project stage of construction, where a majority of OT procurements are complete and fulfilled, we find the OT Vendor Procurement Matrix to continue to be useful," Christopher Romsos, Datapresence Systems Engineer for the Regional Class Research Vessel (RCRV) said. "Despite having contracts in place and work well underway at the time the matrix was published, we realized that the OT Vendor Procurement Matrix could be leveraged as a discovery tool to inform our Cyber Risk Management Planning needs. We're in a more informed position now for our CRMP activities because the matrix provided us with something we could easily use in the field and that was designed to assess cyber risk in OT systems,” he said.

The Secure by Design team will be moderating a panel for in-person attendees later this week at the NSF Cybersecurity Summit. The Matrix will surely come up as a discussion topic.

Trusted CI Webinar: JSON Web Tokens for Science: Hands on Jupyter Notebook tutorial, Monday August 26th @10am Central

SciAuth's Jim Basney and Derek Weitzel are presenting the talk, JSON Web Tokens for Science: Hands on Jupyter Notebook tutorial, on August 26th at 10am, Central time.

Please register here.

NSF cyberinfrastructure is undergoing a security transformation: a migration from X.509 user certificates to IETF-standard JSON Web Tokens (JWTs). This migration has facilitated a re-thinking of authentication and authorization among cyberinfrastructure providers: enabling federated authentication as a core capability, improving support for attribute, role, and capability-based authorization, and reducing reliance on prior identity-based authorization methods that created security and usability problems. In this webinar, members of the SciAuth project (https://sciauth.org/ - NSF award #2114989) will provide a short, hands-on tutorial for cyberinfrastructure professionals to learn about JWTs, including SciTokens (https://scitokens.org/ - NSF award #1738962). Participants will use Jupyter Notebooks to validate the security of JWTs and experiment with JWT-based authentication and authorization. Participants will gain an understanding of JWT basics suitable for understanding their security and troubleshooting any problems with their use.

Cyberinfrastructure Vulnerabilities 2024 Annual Report

Since 2014, Trusted CI (formerly the Center for Trustworthy Scientific Cyberinfrastructure, a.k.a., CTSC) has delivered concise announcements on critical vulnerabilities that affect the software and cyberinfrastructure (CI) of higher education and scientific research communities. The alerting service began informally in 2014 at Indiana University with the creation of two mailing lists specific to software and infrastructure vulnerabilities. In 2016, the process was formalized by the NSF solicitation for the Cybersecurity Center of Excellence (CCoE) which called for "situational awareness of the current cyber threats to the research and education environment, including those that impact scientific instruments." The two mailing lists were merged and a more formalized process of monitoring external information sources for potential threats was established. These information sources included:

• US-CERT advisories
• RHEL/EPEL advisories
• REN-ISAC Alerts and Advisories
• Security announcements from open source projects such as OpenSSL and OpenSSH
• Announcements from CI projects such as XSEDE, ACCESS CI, Globus, and OSG
• Social media sites such as X/Twitter and Reddit (/r/netsec and /r/cybersecurity)
• News sources such as The Hacker News, Threatpost, The Register, Naked Security, Slashdot, Krebs on Security, SANS Internet Storm Center, and Schneier on Security

The Trusted CI team monitored these sources for vulnerabilities, then determined which ones were of critical interest to the CI community. While there were many cybersecurity issues reported in the news, we strove to alert on issues that affected the CI community in particular. For issues that warranted alerts to the Trusted CI mailing list, we provided guidance on how operators and developers could reduce risks and mitigate threats.

In April of 2024, the Cyberinfrastructure Vulnerabilities alerting service was replaced by the OmniSOC Community Advisory. This semi-monthly newsletter highlights current events and information security news aimed at the research cyberinfrastructure community. We encourage the Trusted CI community to subscribe to the OmniSOC newsletter by sending email to omnisoc-community-advisory-l-subscribe@iu.edu . Additionally, users are encouraged to subscribe to other CVE/vulnerability announcement lists, including:

• CISA
• SANS
• NIST National Vulnerability Database
• OpenCVE

In the first quarter of 2024, the Cyberinfrastructure Vulnerabilities team discussed 11 vulnerabilities and issued 4 alerts to 188 subscribers. Since 2014, the team has issued nearly 200 alerts to the community. 

The archives of alerts issued since 2017 are available here and here.
