In recent years, the rapid development of LLMs has brought opportunities for innovation in various areas of an organization from customer services to decision-making. However, organizations lacking comprehensive security strategies may face the risks of data breaches, compromised AI models, or even the consequences of non-compliance and damaged reputation. Therefore, organizations need to take a systematic approach to their security defenses. 

The “LEARN” framework is a 5-stage approach that provides comprehensive security management:  

The "Layer" stage focuses on clarifying system boundaries to allow teams to see the risks of each component clearly and implement corresponding controls. 

The "Evaluate" stage evaluates the potential impact on operations based on current workflows and confidentiality of data, taking into account regulatory requirements, to find out the areas where hardening should be prioritized. Creating inter-department communication channels early on can help resolve issues before they become bigger problems. 

The "Act" stage turns plans into actions, including updating security measures, optimizing workflows, etc. Since LLM applications usually involve external users and third-party integrations, it is necessary to ensure that security measures can work automatically and issue alerts when anomalies occur. 

The "Reinforce" stage verifies the effectiveness of security measures through continuous monitoring and regular testing. This includes collecting system usage logs, emulating attacks, etc. to ensure security defenses are working properly. 

Finally, the "Nurture" stage focuses on building a security culture that ensures security awareness permeates the organization from bottom to top. Organizations need to be able to adapt to changes in the external environment by quickly adjusting internal guidelines and establishing new standards in daily operations.  

With LEARN, organizations can innovate with LLMs while managing their risks properly, taking advantage of market opportunities while ensuring operational continuity. As technologies continue to evolve, this framework will also provide room for adjustment that helps organizations continuously improve their defenses in changing environments.
