Introduction & Overviews


As enterprises are increasingly adopting generative AI (GenAI), including large language models (LLMs), they are more aware of the challenges of GenAI. This is especially true regarding the security of the GenAI ecosystem. Many customers have asked us how to approach GenAI security. Some of them even initiated their own experiments to tackle various aspects of GenAI security. 


To completely grasp the implications of GenAI security, a comprehensive framework is essential. This framework should provide insights into the overall challenges of GenAI security, the different types of attacking vectors of GenAI security, and the different stages of GenAI security. Guided by this framework, enterprises can then start focusing on addressing the specific security challenges they are facing. 


Inspired by real-world data and incidents, we propose the following GenAI cybersecurity framework that encompasses five core security aspects as shown in Figure 1.


To further enhance this framework, our Precision AI technology can be integrated to provide targeted solutions and insights. Precision AI technology, built on a rich security dataset, offers advanced capabilities in detecting and mitigating AI-driven threats, ensuring a robust defense mechanism within the framework.


Precision AI by Palo Alto Networks is our proprietary AI system used specifically for cybersecurity. Precision AI incorporates traditional AI/ML approaches but customizes it for security. Specifically, Precision AI technology brings high-resolution for cyber defenders by centralizing and then analyzing data with security-specific models to help defenders automate detection, prevention and response. Security has now transitioned to a data problem, and it requires data with Precision AI to stop rapidly-evolving bad threats in real time. By trusting products powered by Precision AI, security teams can automate with confidence and achieve security outcomes faster.

By comprehensively addressing these interconnected topics, our framework empowers organizations to have a holistic understanding of GenAI security-related issues. Doing so is critical to unlocking the transformative potential of these technologies while mitigating the associated security risks.


GenAI CyberSecurity Framework 


Some enterprises tend to limit GenAI security to narrow use cases like LLM prompt injection. We believe it is important to holistically consider all five aspects of the framework to completely address GenAI security challenges. 


Hardened GenAI I/O Integrity


Natural language processing (NLP) has seen remarkable advancements, largely thanks to the success of language modeling. However, beneath their veneer of sophistication lies critical security concerns. To bypass security controls, attackers may employ obfuscation techniques like encoding, emojis, or special characters. It is also common to split payloads across inputs to evade input validation. The diversity and sophistication of these prompt injection methods underscore the importance of robust defense mechanisms.


To mitigate the risks associated with prompt injection and other LLM I/O vulnerabilities, organizations and developers should adopt a multi-layered approach to security. This should include input validation to prevent malformed, malicious, or unexpected inputs from reaching the LLM. Equally important is output sanitization to ensure secure output handling processes. This can mitigate the risk of malicious code execution, prevent malicious URL spreading, address content with harmful biases, and prevent data leakage – particularly in response to user-generated queries or inputs.


Products powered by Precision AI can significantly enhance these security measures. By leveraging advanced threat detection capabilities, Precision AI technology provides robust input validation and output sanitization solutions. This integration ensures that sophisticated obfuscation techniques and prompt injection methods are effectively countered, securing GenAI systems from potential threats.


Trusted GenAI Data Lifecycle


GenAI systems often require access to massive and diverse datasets. This data may take many forms from web content and social media to digitized texts and user-generated information. While this abundance of data has propelled the capabilities of AI models, it also introduces significant security risks. Sensitive and proprietary information within these datasets, if mishandled or exposed, could lead to privacy breaches, regulatory issues, and severe reputational damage.


The security challenges in the GenAI landscape are multi-faceted. Unauthorized disclosures can occur at two critical points: the sensitive training data and the GenAI model themselves, which are valuable intellectual assets. The potential for model disclosure and data disclosure raises concerns about privacy breaches and intellectual property theft. Moreover, data/knowledge poisoning also represents a grave risk where attackers intentionally corrupt training data or knowledge bases to manipulate model behavior, trigger biased outputs, or spread misinformation. An example includes tampering with a RAG (Retrieval-Augmented Generation) application's training data to redirect users to malicious websites. Addressing these threats requires a robust GenAI solution that encompasses stringent data validation, continuous model verification, proactive monitoring, and comprehensive user education to mitigate risks effectively and maintain trust in GenAI systems. By using products powered by Precision AI, organizations can effectively mitigate risks, maintain trust in their GenAI systems, and ensure the security and reliability of their AI-powered solutions.


Secure GenAI System Infrastructure


The underlying infrastructure on which GenAI systems run, as well as related software supply chains, introduce a host of attack vectors. Robust security measures must be in place to mitigate the risk of breaches and to ensure system resiliency. The computational resources required to train and operate LLMs, for example, can be an attractive target for adversaries seeking to capitalize on this processing power for illicit purposes. 


To effectively address these security challenges, organizations should prioritize practical security measures such as conducting security audits, implementing multi-factor authentication, establishing incident response plans, and secure coding practices. Continuous vigilance and adaptation are essential in response to evolving threats. Precision AI technology can play a crucial role in this context by leveraging the rich security dataset to provide advanced threat detection and mitigation strategies, ensuring a more robust defense against sophisticated attacks. By taking proactive steps to secure GenAI infrastructure, organizations can mitigate risks and ensure the reliability and resilience of their AI-powered systems.


Trustworthy GenAI Governance


Ethical, transparent, and accountable GenAI development and use are essential. Strong governance protocols help prevent unintended biases, ensure alignment with organizational values, and foster user trust.


Effective governance of GenAI requires alignment with organizational values, precautions against hallucinations, transparency, explainability, and robustness to model drift. Precision AI technology plays a crucial role in this process by providing advanced monitoring capabilities to ensure that GenAI systems remain secure and aligned with ethical standards. By understanding and addressing these key aspects, cybersecurity professionals can help ensure that GenAI is used in a secure, ethical, and accountable manner.


Adversarial GenAI Threat Defense


GenAI empowers cybersecurity attacks by enhancing the efficiency, sophistication, and adaptability of malicious activities. GenAI supports the automation of complex tasks that typically require human intelligence, such as crafting personalized phishing emails or identifying specific vulnerabilities in a system's security. This capability allows cyber attacks to be executed on a much larger scale and at a faster pace, dramatically increasing both the reach and potential impact of these threats. Moreover, GenAI brings a new level of sophistication to cyber attacks. It can analyze vast datasets to determine the most effective attack vectors, tailor messages to specific targets based on their personal data, precisely mimic a trusted individual’s face, voice, and style, and simulate normal user behavior to evade detection systems. 


To adequately defend against GenAI-driven cyber threats, it is essential to recognize the limitations of traditional security measures and understand the need for AI-enhanced security systems in the GenAI era. This is where Precision AI by Palo Alto Networks comes into play.


Precision AI technology counteracts the advanced capabilities of GenAI by utilizing AI to fight AI. It enhances defensive strategies with precision and efficiency. It can rapidly analyze and respond to potential threats, providing a robust defense against the evolving landscape of cyber attacks. Precision AI technology's ability to adapt and learn from new data ensures that it stays ahead of attackers, offering a critical advantage in protecting systems and data in an increasingly AI-driven threat environment.
