How can Protect AI’s 3 Open Source Security Tools Safeguard AI and ML?

Protect AI Expands its Presence in the Open Source Security World

The Introduction of AI/ML Security Tools under Apache 2.0 Terms

Protect AI, the maker of Huntr, a bug bounty program for open source software (OSS), is making further advancements in the OSS realm by licensing three of its AI/ML security tools under the permissive Apache 2.0 terms. These tools, collectively known as NB Defense, ModelScan, and Rebuff, aim to enhance the security of machine learning projects, particularly those developed using Jupyter Notebooks and shared across the internet.

Addressing Vulnerabilities in Jupyter Notebooks

As Jupyter Notebooks gained popularity among data scientists, they also attracted the attention of hackers due to their power in testing code and packages. In response to this emerging threat, Protect AI developed NB Defense, a pair of tools specifically designed for scanning Notebooks for vulnerabilities, such as secrets, personally identifiable information (PII), CVE exposures, and code subject to restrictive third-party licenses.

The JupyterLab extension, part of NB Defense, detects and fixes security issues within a Notebook. Meanwhile, the CLI tool enables the scanning of multiple Notebooks simultaneously and automatically scans those being uploaded to a central repository. By integrating these tools into their workflow, data scientists and developers can fortify the security of their machine learning projects and safeguard their sensitive information.

Ensuring Secure Sharing of ML Models

With an increasing number of companies developing AI/ML tools for internal use, the need arises for secure sharing of ML models across the internet. Protect AI‘s second tool, ModelScan, addresses this requirement by scanning popular ML model formats, such as Pytorch, Tensorflow, and Keras. It identifies potential security risks related to model serialization, including credential theft, data poisoning, model poisoning, and privilege escalation. By proactively scanning models before sharing, organizations can prevent malicious attacks against their valuable AI assets.

Protecting Large Language Models from Prompt Injection Attacks

In July 2023, Protect AI acquired an existing open-source project called Rebuff, which focuses on addressing prompt injection (PI) attacks. These attacks involve sending malicious inputs to large language models (LLMs) to manipulate outputs, expose sensitive data, and enable unauthorized actions.

Rebuff employs a self-hardening prompt injection detection framework with four layers of defense. Firstly, heuristics filter out potentially malicious input before it reaches the model. Then, a dedicated LLM analyzes incoming prompts to identify potential attacks. A database of known attacks helps the system recognize and fend off similar attacks in the future. Finally, canary tokens modify prompts to detect any potential data leaks.

By implementing Rebuff’s defense mechanisms, organizations leveraging LLMs can significantly enhance the security of their models, reducing the risk of exploitation and data breaches.

The Growing Landscape of AI and the Need for Security

The increasing adoption of artificial intelligence and large language models across organizations of various sizes has led to a surge in tools both to secure and exploit these models. As demonstrated by Protect AI‘s recent introduction of security tools, the industry acknowledges the importance of protecting AI/ML projects from potential threats. However, malicious actors also continue to innovate and find new ways to compromise these systems.

For instance, HiddenLayer, the winner of this year’s RSA Conference Innovation Sandbox, focuses on securing AI models against tampering. Additionally, major players like Microsoft have released their own open-source tools and security frameworks to protect AI systems against adversarial attacks.

The recent security flaws discovered in TorchServe emphasize the real-world risks faced even by prominent entities like major retailers and cloud service providers.

Conclusion and Advice

Protect AI‘s decision to license its AI/ML security tools under the permissive Apache 2.0 terms marks a significant step in fortifying the open source software ecosystem. By making these tools available on GitHub, Protect AI is not only contributing to the security of AI/ML development but also enabling the broader community to benefit from them.

In the face of evolving threats to AI and ML projects, it is crucial for developers and organizations to prioritize security and take proactive measures to safeguard their assets. Integrating security tools like NB Defense, ModelScan, and Rebuff can greatly enhance the resilience of AI systems against potential vulnerabilities and attacks.

However, it is essential to remember that security measures are not foolproof, and vigilance is key. As the AI landscape evolves, both defenders and attackers will continue to push boundaries. Organizations must stay informed about the latest security developments, regularly update their security tools, and foster a culture of security awareness among their teams.

Ultimately, securing AI and ML projects requires a multi-faceted approach that combines technological advancements, community collaboration, and organizational commitment. By prioritizing security, the AI community can mitigate risks and continue to innovate with confidence.
