• Origin: Where did the AI tool come from? Was it developed in-house, sourced from a third-party vendor, or derived from an open-source repository?
• Operational Status: Is the AI tool currently active, in development, or deprecated? Understanding each tool's lifecycle stage helps prioritize security efforts.

This foundational step is crucial for identifying potential vulnerabilities and gaps in your security infrastructure. By knowing exactly what AI tools are in use, you can better assess and manage their security risks.

Next, perform a pre-trained model audit. Track all pre-trained AI models sourced from public repositories. This involves:

• Cataloging Pretrained Models: Document all pre-trained models in use, noting their source, version, and specific use case within your organization.
• Assessing Model Integrity: Verify the authenticity and integrity of pre-trained models to ensure they have not been tampered with or corrupted.
• Monitoring Network Traffic: Continuously monitor network traffic for unauthorized downloads of pre-trained models. This helps prevent rogue elements from infiltrating your system.

Monitoring network traffic is essential to prevent unauthorized access and the use of pre-trained models, which can introduce security vulnerabilities. This vigilant oversight protects against unseen threats and ensures compliance with intellectual property and licensing agreements. Unauthorized use of pre-trained models can lead to legal and financial repercussions, so it is important to ensure that all models are used in accordance with their licensing terms.

By thoroughly understanding your AI ecosystem through an AI usage inventory and pre-trained model audit, you establish a strong foundation for securing your AI infrastructure. This proactive approach helps identify and mitigate risks, ensuring the safe and effective use of AI within your organization.

Step 3: Risk Assessment and Threat Modeling

With a clear inventory in place, assess the scope of your AI development. Understand the extent of your AI projects, including the number of dedicated personnel, such as data scientists and engineers, and the scale of ongoing initiatives. This assessment provides a comprehensive view of your AI landscape, highlighting areas that may require additional security measures. Specifically, consider the following aspects:

• Team Composition: Identify the number and roles of personnel involved in AI development. This includes data scientists, machine learning engineers, software developers, and project managers. Understanding your team structure helps assess resource allocation and identify potential skill gaps.
• Project Scope: Evaluate the scale and complexity of your AI projects. Are they small-scale pilots, or are they large-scale deployments across multiple departments? Assessing the scope helps understand the potential impact and the level of security needed.
• Resource Allocation: Determine the resources dedicated to AI projects, including budget, infrastructure, and tools. This helps identify whether additional investments are needed to bolster security measures.

Afterward, a thorough risk and benefit analysis will be conducted. Identify and evaluate potential threats, such as data breaches, adversarial attacks, and misuse of AI systems. Simultaneously, assess the benefits to understand the value of these systems to your organization. This dual analysis helps prioritize security investments and develop strategies to mitigate identified risks effectively. Consider the following steps:

• Risk Identification: List all potential threats to your AI systems. These include data breaches, unauthorized access, adversarial attacks, model theft, and algorithmic bias. Consider both internal and external threats.
• Risk Evaluation: Assess the likelihood and impact of each identified risk. Determine how each risk could affect your organization in terms of financial loss, reputational damage, operational disruption, and legal implications.
• Benefit Assessment: Evaluate the benefits of your AI systems. This includes improved efficiency, cost savings, enhanced decision-making, competitive advantage, and innovation. Quantify these benefits to understand their value to your organization.
• Prioritization: Based on the risk and benefit analysis, prioritize your security investments. Focus on mitigating high-impact and high-likelihood risks first. Ensure that the benefits of your AI systems justify the costs and efforts of implementing security measures.

By assessing the scope of your AI development and conducting a thorough risk and benefit analysis, you gain a holistic understanding of your AI landscape. This allows you to make informed decisions about where to allocate resources and how to mitigate risks effectively, ensuring the security and success of your AI initiatives.

Summary 

For decades, the concept of red teaming has been adapted from its military roots to simulate how a threat actor could bypass defenses put in place to secure an organization. For many organizations, employing or contracting with ethical hackers to simulate attacks against their computer systems before adversaries attack is a vital strategy to understand where their weaknesses are. As Artificial Intelligence becomes integrated into everyday life, red-teaming AI systems to find and remediate security vulnerabilities specific to this technology is becoming increasingly important. 

https://www.youtube.com/watch?v=LsgQ5fk2Dks

What is AI Red Teaming

The White House Executive Order on the Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence defines AI red teaming as follows: 

“The term “AI red-teaming” means a structured testing effort to find flaws and vulnerabilities in an AI system, often in a controlled environment and in collaboration with developers of AI.  Artificial Intelligence red-teaming is most often performed by dedicated “red teams” that adopt adversarial methods to identify flaws and vulnerabilities, such as harmful or discriminatory outputs from an AI system, unforeseen or undesirable system behaviors, limitations, or potential risks associated with the misuse of the system.”

In traditional machine learning, the timing of the attack will dictate the tactics and techniques that can be employed. At a high level, this would either be during training time or decision time. Training time would employ techniques such as data poisoning or model tampering. On the other hand, decision, or inference, time attacks would leverage techniques such as model bypass.

The MITRE ATLAS framework offers an excellent description of the tactics and techniques that can be used against such systems, and we’ve also written about some of these techniques. In recent months, generative AI systems, such as Large Language Models (LLMs) and GPTs, have become increasingly popular. While there has yet to be a consensus on a true taxonomy of attacks against these systems, we can attempt to classify a few. Prompt Injection is probably one of the most well-known attacks against LLMs today. Yet numerous other attack techniques against LLMs exist, such as indirect prompt injection, jailbreaking, and many more. While these are the techniques, the attacker’s goal could be to generate illegal or copyrighted material, produce false or biased information, or leak sensitive data.

Red Team vs Penetration Testing vs Vulnerability Assessment

Vulnerability assessments are a more in-depth systematic review that identifies vulnerabilities within an organization or system and provides a prioritized list of findings with recommendations on how to resolve them. The important distinction here is that these assessments won’t attempt to exploit any of the discovered vulnerabilities. 

Penetration testing, often referred to as pen testing, is a more targeted attack to check for exploitable vulnerabilities. Whereas the vulnerability assessment does not attempt any exploitation, a pen testing engagement will. These are targeted and scoped by the customer or organization, sometimes based on the results of a vulnerability assessment. In the concept of AI, an organization may be particularly interested in testing if a model can be bypassed. Still, techniques such as model hijacking or data poisoning are less of a concern and would be out of scope. 

Red teaming is the process of employing a multifaceted approach to testing how well a system can withstand an attack from a real-world adversary. It is particularly used to test the efficacy of systems, including their detection and response capabilities, especially when paired with a blue team (defensive security team). These attacks can be much broader and encompass human elements such as social engineering. Typically, the goals of these types of attacks are to identify weaknesses and how long or far the engagement can succeed before being detected by the security operations team. 

Benefits of AI Red Teaming

Running through simulated attacks on your AI and ML ecosystems is critical to ensure comprehensiveness against adversarial attacks. As a data scientist, you have trained the model and tested it against real-world inputs you would expect to see and are happy with its performance. Perhaps you’ve added adversarial examples to the training data to improve comprehensiveness. This is a good start, but red teaming goes deeper by testing your model’s resistance to well-known and bleeding-edge attacks in a realistic adversary simulation. 

This is especially important in generative AI deployments due to the unpredictable nature of the output. Being able to test for harmful or otherwise unwanted content is crucial not only for safety and security but also for ensuring trust in these systems. There are many automated and open-source tools that help test for these types of vulnerabilities, such as LLMFuzzer, Garak, or PyRIT. However, these tools have drawbacks, making them no substitute for in-depth AI red teaming. Many of these tools are static prompt analyzers, meaning they use pre-written prompts, which defenses typically block as they are previously known. For the tools that use dynamic adversarial prompt generation, the task of generating a system prompt to generate adversarial prompts can be quite challenging. Some tools have “malicious” prompts that are not malicious at all. 

Real World Examples

One such engagement we conducted with a client highlights the importance of running through these types of tests with machine learning systems. This financial services institution had an AI model that identified fraudulent transactions. During the testing, we identified various ways in which an attacker could bypass their fraud models and crafted adversarial examples. Through this testing, we could work with the client and identify examples with the least amount of features modified, which provided guidance to data science teams to retrain the models that were not susceptible to such attacks. 

In this case, if adversaries could identify and exploit the same weaknesses first, it would lead to significant financial losses. By gaining insights into these weaknesses first, the client can fortify their defenses while improving their models' comprehensiveness. Through this approach, this institution not only protects its assets but also maintains a stellar customer experience, which is crucial to its success. 

Regulations for AI Red Teaming

In October 2023, the Biden administration issued an Executive Order to ensure AI's safe, secure, and trustworthy development and use. It provides high-level guidance on how the US government, private sector, and academia can address the risks of leveraging AI while also enabling the advancement of the technology. While this order has many components, such as

responsible innovations, protecting the American worker, and other consumer protections, one primary component is AI red teaming. 

This order requires that organizations undergo red-teaming activities to identify vulnerabilities and flaws in their AI systems. Some of the important callouts include:

• Section 4.1(a)(ii) - Establish appropriate guidelines  to enable developers of AI, especially of dual-use foundation models, to conduct AI red-teaming tests to enable deployment of safe, secure, and trustworthy systems.
• Section 4.2(a)(i)(C) - The results of any developed dual-use foundation model’s performance in relevant AI red-team testing.
  • Companies developing or demonstrating an intent to develop potential dual-use foundation models to provide the Federal Government, on an ongoing basis, with information, reports, or records

• Section 10.1(b)(viii)(A) - External testing for AI, including AI red-teaming for generative AI
• Section 10.1(b)(viii)(A) - Testing and safeguards against discriminatory, misleading, inflammatory, unsafe, or deceptive outputs, as well as against producing child sexual abuse material and against producing non-consensual intimate imagery of real individuals (including intimate digital depictions of the body or body parts of an identifiable individual), for generative AI

Another well-known framework that addresses AI Red Teaming is the NIST AI Risk Management Framework (RMF). The framework's core provides guidelines for managing the risks of AI systems, particularly how to govern, map, measure, and manage. Although red teaming is not explicitly mentioned, section 3.3 offers valuable insights into ensuring AI systems are secure and resilient.

“Common security concerns relate to adversarial examples, data poisoning, and the exfiltration of models, training data, or other intellectual property through AI system endpoints. AI systems that can maintain confidentiality, integrity, and availability through protection mechanisms that prevent unauthorized access and use may be said to be secure.”

The EU AI Act is a behemoth of a document, spanning more than 400 pages outlining requirements and obligations for organizations developing and using AI. The concept of red-teaming is touched on in this document as well: 

“require providers to perform the necessary model evaluations, in particular prior to its first placing on the market, including conducting and documenting adversarial testing of models, also, as appropriate, through internal or independent external testing.”

Conclusion

AI red teaming is an important strategy for any organization that is leveraging artificial intelligence. These simulations serve as a critical line of defense, testing AI systems under real-world conditions to uncover vulnerabilities before they can be exploited for malicious purposes. When conducting red teaming exercises, organizations should be prepared to examine their AI models thoroughly. This will lead to stronger and more resilient systems that can both detect and prevent these emerging attack vectors. AI red teaming goes beyond traditional testing by simulating adversarial attacks designed to compromise AI integrity, uncovering weaknesses that standard methods might miss. Similarly, LLM red teaming is essential for large language models, enabling organizations to identify vulnerabilities in their generative AI systems, such as susceptibility to prompt injections or data leaks, and address these risks proactively

Engaging in AI red teaming is not a journey you should take on alone. It is a collaborative effort that requires cyber security and data science experts to work together to find and mitigate these weaknesses. Through this collaboration, we can ensure that no organization has to face the challenges of securing AI in a silo. If you want to learn more about red-team your AI operations, we are here to help.

To help understand the evolving cybersecurity environment, we developed HiddenLayer’s 2024 AI Threat Landscape Report as a practical guide to understanding the security risks that can affect every industry and to provide actionable steps to implement security measures at your organization. 

Understanding Advancements in Security for AI

Understanding new technologies' vulnerabilities is crucial before implementing security measures. Offensive security research plays a significant role in planning defenses, as initial security measures are often built on the foundation of these offensive insights.

Security for AI is no exception. Early research and tools in this field focused on offensive strategies. Initially, AI attacks were mainly explored in academic papers and through exercises by security professionals. However, there has been a significant shift in the last few years.

Offensive Security Tooling for AI

Just as in traditional IT security, offensive security tools for AI have emerged to identify and mitigate vulnerabilities. While these tools are valuable for enhancing AI system security, malicious actors can also exploit them.

Automated Attack Frameworks

Pioneering tools like CleverHans (2016) and IBM's Adversarial Robustness Toolbox (ART, 2018) have paved the way for testing AI comprehensively. Subsequent tools such as MLSploit (2019), TextAttack (2019), Armory (2020), and Counterfit (2021) have further advanced the field, offering a variety of attack techniques to evaluate AI defenses.

Anti-Malware Evasion Tooling

Specialized tools like MalwareGym (2017) and its successor MalwareRL (2021) focus on evading AI-based anti-malware systems. These tools highlight the need for continuous improvement in security for AI measures.

Model Theft Tooling

KnockOffNets (2021) demonstrates the feasibility of AI model theft, emphasizing the importance of securing AI intellectual property.

Model Deserialization Exploitation

Fickling (2021) and Charcuterie (2022) showcase vulnerabilities in AI model serialization, underscoring the need for secure model handling practices.

Defensive Frameworks for AI

Leading cybersecurity organizations have developed comprehensive defensive frameworks to address the rising threats to AI.

MITRE ATLAS

Launched in 2021, MITRE ATLAS (Adversarial Threat Landscape for Artificial-Intelligence Systems) provides a knowledge base of adversarial tactics and techniques. Modeled after the MITRE ATT&CK framework, ATLAS helps professionals stay updated on AI threats and defenses.

“This survey demonstrates the prominence of real-world threats on AI-enabled systems, with 77% of participating companies reporting breaches to their AI applications this year. The MITRE ATLAS community is dedicated to characterizing and mitigating these threats in a global alliance. We applaud our community collaborators who enhance our collective ability to anticipate, prevent, and mitigate risks to AI systems, including HiddenLayer and their latest threat report.”

– Dr. Christina Liaghati, MITRE ATLAS Lead

NIST AI Risk Management Framework

Released in January 2023, the NIST AI Risk Management Framework (AI RMF) offers guidance for the responsible design, deployment, and use of AI systems, promoting trust and security in AI.

Google Secure AI Framework (SAIF)

Introduced in June 2023, SAIF outlines best practices for securing AI systems, emphasizing strong security foundations, automated defenses, and contextualized risk management.

Policies and Regulations

Global policies and regulations are being established to ensure AI's safe and ethical use. The EU's GDPR and AI Act, OECD AI Principles, and national frameworks like Singapore's Model AI Governance Framework and the US's AI Bill of Rights highlight the growing emphasis on security for AI and governance.

Concluding Thoughts

As AI technology evolves, so must the security measures that secure it. By combining offensive and defensive strategies, leveraging comprehensive frameworks, and adhering to evolving regulations, the industry can better safeguard AI systems against emerging threats. Collaboration between academia, industry, and policymakers is essential to anticipate and mitigate risks effectively.

Summary

OpenAI revolutionized the world by launching ChatGPT, marking a pivotal moment in technology history. The AI arms race, where companies speed to integrate AI amidst the dual pressures of rapid innovation and cybersecurity challenges, highlights the inherent risks in AI models. HiddenLayer’s Model Scanner is crucial for identifying and mitigating these vulnerabilities. From the surge of third-party models on platforms like Hugging Face to the Wild West-like rush for AI dominance, this article offers insights into securing AI’s future while enabling businesses to harness its transformative power safely.

Introduction

November 30, 2022 will go down in history as a major milestone in the history of technology. That was the day OpenAI made ChatGPT publicly available to the masses. Although, as a society, we’ve been experimenting with artificial intelligence academically since the 1950s, and many industries (finance, defense, healthcare, insurance, manufacturing, cybersecurity, and more.) have been putting AI into practical use since the early 2010s, OpenAI’s launch of ChatGPT helped the general public truly understand the vast benefits AI has on technology, economy, and society. We now find ourselves in the middle of an AI Arms Race with practically every enterprise and start-up company trying to rapidly embrace and adopt AI to help solve their business and/or technical problems. 

AI Acceleration vs AI Hesitancy

The sudden acceleration of AI adoption in this arms race puts immense pressure on companies’ cybersecurity organizations to facilitate AI initiatives without impeding progress. Many company CISOs and their teams have “AI Hesitancy” because they have not been afforded the time to understand the full scope of the cybersecurity risk and attack threat landscape to put the people, processes, procedures, and products in place to embrace AI safely and securely. In A Beginner’s Guide to Securing AI for SecOps, we offer a primer for Security Operations teams to consider securing AI. 

AI acceleration causes cybersecurity risks inherent in AI models. HiddenLayer’s AI Model Scanner can empower cybersecurity teams to help companies adopt AI while minimizing cybersecurity risks and attacks. 

The Wild Wild West of the New AI Frontier

Today’s AI technological frontier is reminiscent of the Wild West of America in the 1800s. Like early pioneers, those venturing into this new era are motivated by its promise, and first-movers gain significant advantages by staking their claim early before the area becomes saturated. As success stories emerge, they attract an influx of others, including unwanted threat actors. The frontier remains largely lawless despite new regulations due to a lack of enforcement and security resources. Consequently, organizations must take proactive steps to protect themselves and their AI assets.

AI Rush: Supply vs Demand

The hyper-demand for AI and machine learning models is exacerbated by the lack of supply of AI expertise (data scientists, ML engineers, etc) and has created a market explosion of third-party and open-source AI Models. A symptom of this hyper-demand can be seen in the growth of Hugging Face. Billed as the “GitHub of AI Models,” Hugging Face has established itself as the leader in AI Model Marketplaces, where anyone can download AI Models to bootstrap their adoption of AI. In 2023, Hugging Face had about 50,000 models. Today, in a little over a year, they have exceeded 650,000 models created by AI companies and creators. It is clear that we are in the middle of a gold rush in the era of the Dot AI Boom. 

Downloading third-party models without validation, attestation, or insights into the trustworthiness of AI models exposes companies to significant cybersecurity risks. Recognizing this as an issue that could impede AI adoption, Microsoft uses HiddenLayer to scan the models in their curated Azure AI catalog on behalf of their customers. 

Exploitation of Malicious AI Models

AI Robbery

AI models are uniquely attractive to threat actors and ripe for attack because they contain both sensitive data and code execution capabilities. Threat actors commonly utilize malicious code execution to access sensitive data and intel. In this scenario, the keys to the safe are attached to the safe itself. 

What are the most common threats to AI Model Files?

• Arbitrary Code Execution – Arbitrary code can be executed as part of a model format’s intended functionality or by exploiting a vulnerability. An attacker may run any code to compromise a target system, exfiltrate data, poison training data sets, coin mining, encrypt the machine, or worse.
• Network Requests – The machine learning model may execute network requests, allowing for data exfiltration and remote access to a restricted environment.
• Embedded Payloads – Malicious executables and other files can be embedded within a machine learning model in several ways: either appended to a model, injected into the weights and biases via steganography, or bundled as part of a model archive.
• Decompression Vulnerabilities – Some machine learning models can be compressed to a small size when saved but can be designed to expand to an enormous size on load, crashing the system it is loaded on.
• Unsafe Python Modules – Unsafe modules within the Python ecosystem can execute arbitrary code and be used to compromise a machine.
• File System Access – The machine learning model can access the local file system, allowing for data exfiltration or arbitrary file writes to the file system.
• Exploitation – Machine learning models are not impervious to typical vulnerabilities such as buffer overflows and path traversals when parsing the model file. These can then be used to exploit the host machine to achieve arbitrary code execution, arbitrary file writes, and more. 

HiddenLayer Model Scanner

HiddenLayer’s Model Scanner performs a deep introspective analysis of AI models with the industry’s most comprehensive breadth and depth of coverage. It recognizes and parses all the major model file formats to identify cybersecurity risks and threats embedded in the model’s layers, tensors, and functionality using HiddenLayer’s patented detection techniques. 

AI Model Format War

AI  Models come in all types of flavors. Each one of them has nuances and capabilities that can expose their vulnerabilities to be exploited. Some of the most commonly used AI Model formats seen in the wild are:

Model FormatDescriptionFile ExtensionsGGUFGGUF is a file format for storing models for inference with GGML and executors based on GGML. GGUF is a binary format that is designed for fast loading and saving of models, and for ease of reading. Models are traditionally developed using PyTorch or another framework and then converted to GGUF for use in GGML.ggufH5H5 is a file format used to organize large datasets and can contain multiple files that can potentially reference each other. It’s very common to bundle datasets, weights, or supporting scripts in an h5 file..h5KerasKeras is a high-level neural network API written in Python and runs on top of multiple open-source ML frameworks like TensorFlow. Keras model format can be a directory or a single file..keras, .tfNemoNemo models are used to train and reproduce Conversational AI models and are compatible with the PyTorch ecosystem..nemoNumPyA file type for storing N-dimensional arrays, a Python datatype that is very common in machine learning..npyONNXA machine learning file format that allows for easy exchange between different frameworks. ONNX file stores model information as a graph object..onnxPickleA file type that serializes Python objects. Can contain data, trained models, and weights..pkl, .picklePytorchModel format primarily used by PyTorch ML framework. The format is a compressed ZIP archive containing a data.pkl (pickle file) and associated model weights. .pt, .bin, .zipSafetensorsSafetensors is a safe and fast file format for storing and loading tensors. Safetensors are meant to replace PyTorch models distributed as pickles with safer versions, where only the tensor is serialized without any surrounding code and logic..safetensorsTensorflowTensorFlow is a free and open-source software library for machine learning and artificial intelligence. It can be used across a range of tasks but has a particular focus on training and inference of deep neural networks. Tensorflow native save format (.tf) is a directory containing variables and three protobuf files. The SavedModel format persists the graph of a TensorFlow model to disk..savedmodel, .tf, .pb

Security Checkpoints Throughout the AI Model Lifecycle

AI model training and development process can be very dynamic, with constant changes to data, functionality, weights, and biases from a team of contributors. This dynamic nature makes implementing traditional change control, code audits, and chain of custody difficult.  

HiddenLayer Model Scanner should be used to implement security checkpoints at multiple stages of the AI Operations lifecycle to ensure the security and trustworthiness of the model:

1. Scan third-party models upon initial download to ensure the foundational model is free of vulnerabilities or malicious code. This should be done before feeding it sensitive training data. 
2. Perform scans on all models within an MLOps Tools registry/catalog to identify any existing latent security risks.
3. Scan models whenever a new version is created to identify supply chain attacks or inadvertent inclusions of new vulnerabilities
4. Enforce model scanning before transitioning to production to confirm their safety and take a snapshot of the last known safe state.

HiddenLayer AISec Platform integrates with MLOps tools (such as Microsoft AzureML, Databricks, and others) to synchronize and aggregate different MLOps tools’ model registry into HiddenLayer’s Model Inventory to give security teams a single view of all the company’s models in development. 

Detection Analysis & Incident Response

When the Model Scanner detects an issue with an AI model, it provides insightful details to allow security teams to collaborate with data science teams to investigate further. In this example, the scan of a Keras file found that the model has a lambda function that allows for arbitrary code execution. 

The presence of this function could allow a threat actor to exploit its capabilities to execute malware, a backdoor, or any other capability to accomplish their goal. Many questions arise from this single detection:

1. Was this vulnerability already embedded in the 3rd party model used as the foundation for this version?
2. Was the Data Science team aware of this capability in the model?
3. If this comes as a surprise, could this be evidence of a supply chain attack by an external threat actor, an internal threat, or a result of a compromised credential?
4. If the Data Science team was aware of the functionality, perhaps they felt it was important for the model to deliver on its purpose but were unaware of the cybersecurity risks it poses to the company.

By detecting this early in the MLOps lifecycle and gaining valuable insight from the detection details and subsequent investigation, security teams could save data science teams and the company time and money spent on the training and development of insecure AIModels or, worse, a potential breach resulting from the exploitation of the vulnerability. 

Conclusion

Companies can go from “AI Hesitancy” to “AI Acceleration” if they take the steps to include security into their AI adoption early in their journey. HiddenLayer AISec Platform and Model Scanner can be used as security checkpoints at key milestones in the MLOps life cycle to identify embedded vulnerabilities and malicious code within AI Models, reducing the company’s risk of attacks and breaches and increasing their AI Security Posture. 

Introduction

It’s been just a few short weeks since RSAC 2024, an event that left a lasting impression on all who attended. This year, the theme “The Art of the Possible” resonated deeply, showcasing the industry’s commitment to exploring new horizons and embracing innovative ideas. It was inspiring to witness the collective enthusiasm for Possibility Thinking, a cognitive perspective that focuses on exploring potential opportunities and imagining various scenarios without being constrained by current realities or limitations. It involves a mindset open to new ideas, creative solutions, and innovative thinking. The theme and general ambiance set the stage perfectly for us to launch something big, the Security for AI Council. 

In the security industry, we are accustomed to thinking about the possibility of harm, which can cause a pause in innovation in some organizations. At HiddenLayer, we believe that when it comes to AI, any organization can go from pause to possibilities. Those who can understand the risks AI can create and can focus on practical solutions to mitigate those risks will be able to unlock the enormous potential AI has to create worldwide social and economic benefits.  

Launching the Security for AI Council

That is why we created the Security for AI Council. The council’s mission is to revolutionize the cybersecurity industry by spearheading the secure adoption of AI, the most impactful technology of our time. We want to empower the industry to fully realize AI’s potential while ensuring its usage is secure and responsible.
