AI Risk Management Framework

 

We list notable NIST projects or efforts related to LLMs, based on available information from NIST’s publications and initiatives. These projects emphasize NIST’s role in advancing measurement science, standards, and guidelines for trustworthy AI systems, including LLMs. Note that some projects are specific studies, while others are broader programs that encompass LLMs.
  • Evaluating LLMs for Real-World Vulnerability Repair in C/C++ Code
    NIST conducted a study to evaluate the capability of advanced LLMs, such as ChatGPT-4 and Claude, in repairing memory corruption vulnerabilities in real-world C/C++ code. The project curated 223 code snippets with vulnerabilities like memory leaks and buffer errors, assessing LLMs’ proficiency in generating localized fixes. This work highlights LLMs’ potential in automated code repair and identifies limitations in handling complex vulnerabilities.
  • Translating Natural Language Specifications into Access Control Policies
    This project explores the use of LLMs for automated translation and information extraction of access control policies from natural language sources. By leveraging prompt engineering techniques, NIST demonstrated improved efficiency and accuracy in converting human-readable requirements into machine-interpretable policies, advancing automation in security systems.
  • Assessing Risks and Impacts of AI (ARIA) Program
    NIST’s ARIA program evaluates the societal risks and impacts of AI systems, including LLMs, in realistic settings. The program includes a testing, evaluation, validation, and verification (TEVV) framework to understand LLM capabilities, such as controlled access to privileged information, and their broader societal effects. This initiative aims to establish guidelines for safe AI deployment.
  • AI Risk Management Framework (AI RMF)
    NIST developed the AI RMF to guide the responsible use of AI, including LLMs. This framework provides a structured approach to managing risks associated with AI systems, offering tools and benchmarks for governance, risk assessment, and operationalizing trustworthy AI across various sectors. It’s widely applied in LLM-related projects.
  • AI Standards “Zero Drafts” Pilot Project
    Launched to accelerate AI innovation, this project focuses on developing AI standards, including those relevant to LLMs, through an open and collaborative process. It aims to create flexible guidelines that evolve with LLM advancements, encouraging input from stakeholders to ensure robust standards.
  • Technical Language Processing (TLP) Tutorial
    NIST collaborated on a TLP tutorial at the 15th Annual Conference of the Prognostics and Health Management Society to foster awareness and education on processing large volumes of text using machine learning, including LLMs. The project explored how LLMs can assist in content analysis and topic modeling for research and engineering applications.
  • Evaluation of LLM Security Against Data Extraction Attacks
    NIST investigated vulnerabilities in LLMs, such as training data extraction attacks, using the example of GPT-2 (a predecessor to modern LLMs). This project, referencing techniques developed by Carlini et al., aims to understand and mitigate privacy risks in LLMs, contributing to safer model deployment.
  • Fundamental Research on AI Measurements
    As part of NIST’s AI portfolio, this project conducts fundamental research to establish scientific foundations for measuring LLM performance, risks, and interactions. It includes developing evaluation metrics, benchmarks, and standards to ensure LLMs are reliable and trustworthy in diverse applications.
  • Adversarial Machine Learning (AML) Taxonomy for LLMs
    NIST developed a taxonomy of adversarial machine learning attacks, including those targeting LLMs, such as evasion, data poisoning, privacy, and abuse attacks. This project standardizes terminology and provides guidance to enhance LLM security against malicious manipulations, benefiting both cybersecurity and AI communities.
  • Use-Inspired AI Research for LLM Applications
    NIST’s AI portfolio includes use-inspired research to advance LLM applications across government agencies and industries. This project develops guidelines and tools to operationalize LLMs responsibly, focusing on practical implementations like text summarization, translation, and question-answering systems.

Remarks:

  • These projects reflect NIST’s focus on evaluating, standardizing, and securing LLMs rather than developing LLMs themselves. NIST’s role is to provide frameworks, guidelines, and evaluations to ensure trustworthy AI.
  • Some projects, like ARIA and AI RMF, are broad programs that encompass LLMs among other AI systems, but they include specific LLM-related evaluations or applications.

 

Three Felonies a Day: How the Feds Target the Innocent

Department of Justice | June 24, 2004

The average professional in this country wakes up in the morning, goes to work, comes home, eats dinner, and then goes to sleep, unaware that he or she has likely committed several federal crimes that day. Why? The answer lies in the very nature of modern federal criminal laws, which have exploded in number but also become impossibly broad and vague.

In Three Felonies a Day, Harvey A. Silverglate reveals how federal criminal laws have become dangerously disconnected from the English common law tradition and how prosecutors can pin arguable federal crimes on any one of us, for even the most seemingly innocuous behavior.

The volume of federal crimes in recent decades has increased well beyond the statute books and into the morass of the Code of Federal Regulations, handing federal prosecutors an additional trove of vague and exceedingly complex and technical prohibitions to stick on their hapless targets.

The dangers spelled out in Three Felonies a Day do not apply solely to “white collar criminals,” state and local politicians, and professionals. No social class or profession is safe from this troubling form of social control by the executive branch, and nothing less than the integrity of our constitutional democracy hangs in the balance.

Community Risk Assessment

Château de Meudon

We have advocated education community risk management concepts since 2007; primarily in NFPA Standard 1300 — Standard on Community Risk Assessment and Community Risk Reduction Plan Development (formerly NFPA 1600).  The content of this title is close-coupled with FEMA’s National Incident Management System.   

Recently the National Fire Protection Association Standards Council moved to consolidate its community risk management titles as described below.  

“NFPA 1660 is in a custom cycle due to the Emergency Response and Responder Safety Document Consolidation Plan (consolidation plan) as approved by the NFPA Standards Council.  As part of the consolidation plan, NFPA 1660 (combining Standards NFPA 1600, NFPA 1616, and NFPA 1620) is open for public input with a closing date of November 13, 2020.”

Thus, NFPA 1600 is being sunsetted as a separate consensus product, its substance rolled into the new NFPA 1660.  CLICK HERE for the new landing page for NFPA 1660.

Two links below provide a sense of the back-and-forth in the technical committee meetings:

1600_F2018_EMB_AAA_FD_PIResponses

1600_F2018_EMB_AAA_SRReport

Discussion about school and university security are noteworthy.

As described on its title page, this product will be reconfigured as NFPA 1660 Standard on Community Risk Assessment, Pre-Incident Planning, Mass Evacuation, Sheltering, and Re-entry Programs.   The title suggests that NFPA 1660 is being developed to meet market need for conformance and teaching tools.  You may track movement in the concepts in the links below; many of them administrative:

Emergency Management and Business Continuity

Mass Evacuation and Sheltering

Pre-Incident Planning 

NFPA 1660 will likely require one or two more revision cycles to stabilize

Public consultation on the Second Draft (NITMAM) closes September 9th.  You may submit public input directly to NFPA by CLICKING HERE.  We will have hosted several Security colloquia ahead of this deadline during which we will drill into technical and policy specifics.

University of Tennessee

 

We maintain this title on our periodic Security, Disaster and Risk colloquia during which time  our thoughts on the economic burden of the expanding constellation of risk management standards will be known.  Thoughts that we are reluctant to write.   See our  CALENDAR for the next online meeting; open to everyone.

Risk Assessment in Emergency Facilities

 

Critical Operations Power Systems: Improving Risk Assessment in Emergency Facilities with Reliability Engineering

University of Michigan | Ann Arbor, Michigan
HP Critical Facilities Services | Bethesda, Maryland
Mark Beirne

DLB Associates | Chicago, Illinois

Abstract. The key feature of this article is the application of quantitative method for evaluating risk and conveying the results into a power system design that is scaled according to hazards present in any given emergency management district. These methods employ classical lumped parameter modeling of power chain architectures and can be applied to any type of critical facility, whether it is a stand-alone structure, or a portion of stand-alone structure, such as a police station or government center. This article will provide a risk assessment roadmap for one of the most common critical facilities that should be designated as COPS per NEC 708-a 911 call center. The existing methods of reliability engineering will be used in the risk assessment.

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.

Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.

There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.

There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:

  1. Heated Job Site Trailers: These trailers are equipped with heating systems that keep workers warm and comfortable while they take breaks or work on plans. This helps to keep morale up and prevent cold-related health issues.
  2. Insulated Concrete Forms (ICFs): ICFs are prefabricated blocks made of foam insulation that are stacked together to form the walls of a building. The foam insulation provides an extra layer of insulation to keep the building warm during cold winter months.
  3. Warm-Mix Asphalt (WMA): WMA is a type of asphalt that is designed to be used in colder temperatures than traditional hot-mix asphalt. This allows road construction crews to work through the winter months without having to worry about the asphalt cooling and becoming unusable.
  4. Pneumatic Heaters: These heaters are used to warm up the ground before concrete is poured. This helps to prevent the concrete from freezing and becoming damaged during the winter months.
  5. Electrically Heated Mats: These mats are placed on the ground to prevent snow and ice from accumulating. This helps to make the job site safer and easier to work on during the winter months.

Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.

All fifty United States have their own “signature” disaster with which to reckon; some more than others.   California has earthquakes, Florida has hurricanes, Missouri has floods; and so on,  Life and property loss are preventable; but losses will persist because technical solutions notwithstanding, culture determines human behavior.  It is impossible to be alive and safe.

FM Global is one of several organizations that curate privately developed consensus products that set the standard of care for many industries; education communities among them.  These standards contribute to the reduction in the risk of property loss due to fire, weather conditions, and failure of electrical or mechanical equipment.  They incorporate nearly 200 years of property loss experience, research and engineering results, as well as input from consensus standards committees, equipment manufacturers and others.

If you want FMGlobal as your insurance carrier, or to supplement your organization’s self-insurance program, then you will likely be assigned an FMGlobal conformity professional.

A scan of its list data sheets indicate a number of noteworthy updates of documents establishing minimum requirements for safety technologies common in education facilities:

Snow Management

“A Morning Snow–Hudson River” 1910 George Wesley Bellows | Smithsonian American Art Museum

This time of year in the Northern Hemisphere we keep an eye on snow management  standards; among them titles developed by the Accredited Snow Contractors Association.  The barriers to entry into this domain are relatively low and, arguably undisciplined; hence the need for standards setting.  Even when only partially adopted, use of ANSI accredited standards reduces the “wheel reinvention” that is common to the business side of the education industry when new initiatives, or continuous improvement programs are undertaken without consideration of already existing leading practice discovery by ANSI-accredited technical committees.  Start here:

ASCA Standards Home Page

The parent title for the emergent ASCA bibliography is System Requirements for Snow and Ice Management Services; free to ASCA members.  The current version is dated 2014 and will likely be updated and/or re-affirmed.  The circumstances of the pandemic has slowed the work of many standards setting committees.  The safety and sustainability concepts remain intact, however.  Among them:

  • If snow can be removed from a lot or hard surface and appropriate room exists, always push the snow as far back as possible beyond the curb or lot edge to make room for additional snow.
  • If snow cannot be removed from a lot or hard surface, always place snow piles on a predetermined spot approved by the client and marked on the snow contractor’s preseason site report.  
  • Do not pile snow in a handicap parking space.
  • Do not bury or plow snow onto a fire hydrant, post indicator valve, or fire hookup along the building wall.
  • Avoid placement of snow piles where thaw/melt off can run across the parking lot surface. Try to place piles near drain grates to avoid icy situations during thaw-and-refreeze periods.
  • Do not push snow against a building.
  • Do not block building doorways or emergency exits.
  • Do not block pedestrian walks or paths with snow piles.
  • Do not push snow onto motor vehicles.
  • Do not plow snow in front of or bury trash containers. Sidewalk labor must shovel inside trash container enclosure for access to the doors. If the container is not in an enclosure, create a clear path to the access doors or panels.

"Liberty, when it begins to take root, is a plant of rapid growth" - (Letter to James Madison, March 2, 1788)“The cold was our pride, the snow was our beauty.” — F. Scott Fitzgerald ('Wiinter Dreams' 1922)

ASCA has more recently released another title — Standard Practice for Procuring and Planning Snow & Ice Management Services — that seems (by its title alone) to be a companion consensus product.  From its prospectus:

This standard of practice covers essential procuring and planning for snow and ice management services. Standards for procuring and planning are essential for business continuity and to improve safety for patrons, tenants, employees, and others in the general public. Knowing how to describe service requirements in a snow and ice management request for proposal (RFP) is an important component to providing effective services, particularly where winter weather is a variable. This standard practice provides guidance on the snow and ice management procurement and planning process to aid in the creation of RFPs, contracts, agreements, and monitoring procedures. This standard will not be submitted for consideration as an ISO, IEC, or ISO/IEC JTC-1 standard.

Apart from these titles, we do not see any recent happening in the ASCA standards setting enterprise.  We will pass information along as it becomes available.  Alternatively, you may communicate directly with ASCA, 5811 Canal Road  Valley View, OH 44125, Ph: (800) 456-0707.  Most education communities employ a combination of permanent and contract staff for these services.

We maintain the ASCA bibliography on our Snow & Ice colloquia  See our CALENDAR for the next online meeting; open to everyone.

NARUC Position on NFPA (NEC) and IEEE (NESC) Harmonization

The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.

The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic.   Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry.  Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry.  Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE.   As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.

August 5, 2022

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus  since many campus power systems are larger than publicly regulated utilities.  Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

Northeast Community College | Norfolk, Nebraska

Today we begin a list of noteworthy changes to be understood in the next few Power colloquia.  See our CALENDAR for the next online meeting.

  1. New rules 190 through 195 cover photovoltaic generating stations.  Rule 116c adds an exception for short lengths of insulated power cables and short-circuit protection if the situation involves fewer than 1,000 volts.
  2. Rule 320B has been revised to clarify separations that apply to communications and supply in different conduit systems.
  3. Table 410-4 is based on the latest arc flash testing on live-front transformers.
  4. Rule 092A adds an exception allowing protection, control, and safety battery systems to not be grounded.
  5. Rules 234 B1, C1, D1 were revised to better present vertical and horizontal wind clearances, and to coordinate requirements with the new Table 234-7.
  6. Rule 120A was revised to provide correction factors for clearances on higher elevations.
  7. Table 253-1 has been revised to reduce the load factor for fiber-reinforced polymer components under wire tension—including dead ends—for Grade C construction.
  8. Rule 410A now requires a specific radio-frequency safety program for employees who might be exposed.
  9. In the Clearances section, as well as in the specification of the Grade of Construction in Table 242-1, the Code further clarifies the use of non-hazardous fiber optic cables as telecom providers continue to expand their networks.
  10. Revisions in the Strength & Loading sections include modified Rule 250C, which addresses extreme wind loading for overhead lines. Two wind maps are now provided instead of the previous single one. A map for Grade B, the highest grade of construction, with a Mean Recurrence Interval (MRI) of 100 years (corresponding to a one percent annual probability of occurrence) is provided in place of the previous 50–90-year MRI map. For Grade C construction, a separate 50-year MRI (two percent annual probability of occurrence) map is now provided. In the previous Code, a factor was applied to the 50–90-year MRI map for application to Grade C.
  11. Changes were also made to the method of determining the corresponding wind loads, consistent with the latest engineering practices as an example of a Code revision focused on public safety, the ground end of all anchor guys adjacent to regularly traveled pedestrian thoroughfares, such as sidewalks, and similar places where people can be found must include a substantial and conspicuous marker to help prevent accidents. The previous Code did not require the marking of every such anchor guy.
  12. Significant revisions were made in Section 14 covering batteries. Previous editions of the code were based on lead-acid technology and batteries only used for backup power. The 2023 Code incorporates the new battery technologies and addresses energy storage and backup power.
  13. A new Section 19 of the code covers photovoltaic generating stations, with sections addressing general codes, location, grounding configurations, vegetation management, DC overcurrent protection, and DC conductors. These new rules accommodate large-scale solar power projects.
  14. In the Clearances section, all rules for wireless antenna structures have been consolidated in the equipment section (Rule 238 and 239), which makes the Code more user-friendly.
  15. A new subcommittee was created focusing on generating stations, with the original subcommittee continuing to address substations.
  16. A working group is investigating Fault Managed Power Systems (FMPS) cables as the technology may be used for 5G networks. The team is looking at possible impacts, including clearances and work rules.

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC.   Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle.  Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.

The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry.   We will be using this workspace as the 2022 NESC continues along its developmental path:

IEEE 2022 NESC Workspace

The revision schedule — also revised in response to the circumstances of the pandemic — is linked below::

NESC 2023 Edition Revision Schedule*

 

The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee.  The next online meeting is shown on the top menu of the IEEE E&H website:

IEEE E&H Committee

We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences.  See our CALENDAR for the next online meeting.

Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database.   Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute.    The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system.   The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.

 

 

* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.
