- **Background** | ||
The paper discusses the widespread use of Industrial Control Systems (ICS) in critical infrastructures and how these systems are becoming vulnerable to cyber threats due to their increased connectivity and advanced features, which could lead to significant disruptions in essential services. | ||
|
||
- **Existing Work** | ||
Current ICS honeypot frameworks are primarily focused on emulating industrial protocols, requiring extensive knowledge and implementation capabilities of network communication protocols. These frameworks face challenges including the proprietary nature of protocols and the level of expert knowledge and manual labor intensity needed for implementation. | ||
|
||
#### Core Contributions | ||
- **Proposal of an LLM-based honeypot design approach** | ||
- **Challenge 1: Accurate Emulation** | ||
Existing systems struggle with precise emulation of industrial environments and require significant manual operations and expert knowledge. LLMPot addresses this by automating and optimizing the creation of honeypots through the use of pre-trained LLMs, thereby reducing manual labor and expert knowledge requirements and more effectively mimicking unique operational behaviors of various industrial protocols and control logic. | ||
|
||
- **Challenge 2: Adaptability** | ||
Traditional honeypots often lack flexibility in adapting to different operational scenarios. LLMPot enhances adaptability by using Large Language Models (LLMs) capable of generating network interactions closely aligned with actual industrial control protocols and physical processes, thus improving the interactivity and indistinguishability of the honeypots. | ||
|
||
#### Implementation and Deployment | ||
LLMPot conducted extensive experiments simulating different industrial protocols and control logic, demonstrating the effectiveness of the LLM-based approach. This method manages to create honeypots with high perceptual quality and interactivity, effectively preventing cyber-attacks. | ||
|
||
#### Summary | ||
LLMPot represents a novel ICS network defense tool that leverages the capabilities of LLMs. By automating the generation of responses closely related to protocols and physical processes, LLMPot significantly enhances the practicality and effectiveness of honeypots. |

#### Background | ||
- **Background** | ||
The paper addresses the issue of aligning and personalizing Large Language Models (LLMs), focusing on their adaptation to different human preferences, learning new skills, and unlearning harmful behavior. Traditional search-based methods like Best-of-N or Monte-Carlo Tree Search, though effective, are impractical due to their high inference costs; on the other hand, using Reinforcement Learning (RL) is computationally more efficient but performs poorly because of optimization challenges in co-training the value function and policy. | ||
|
||
- **Existing Work** | ||
Existing RL methods, while computationally efficient for deployment, are outperformed by simple Best-of-N search due to their need to access model weights and inability to perform real-time composition or fine-grained adaptation. Additionally, performance is often constrained by the challenges of training a value estimator for a non-stationary policy, resulting in noisy policy updates and potentially converging only to suboptimal solutions. | ||
|
||
#### Core Contributions | ||
- **Introduces a framework named Value Augmented Sampling (VAS)** | ||
- **Challenge 1: How to optimize rewards without co-training policy and value function** | ||
Value Augmented Sampling avoids the bi-level optimization process, a known cause of sub-optimality in actor-critic RL methods, by estimating the value function of the reward function using data collected from the base LLM policy. | ||
|
||
- **Challenge 2: How to adapt to new and multiple user preferences without changing model weights** | ||
By keeping the base LLM weights unchanged, VAS can adapt to new and multiple user preferences during deployment without needing any re-training of the LLM, and also to closed-source LLMs where weights are inaccessible. | ||
|
||
#### Implementation and Deployment | ||
VAS outperforms established baselines such as PPO and DPO in standard benchmark tests, performing comparably with Best-of-128 in summarization and multi-turn chat dialogue tasks while being at least six times more computationally efficient. Moreover, VAS provides fine-grained control over adaptation intensity at inference, usable for personalizing outputs according to user preferences. | ||
|
||
#### Summary | ||
Value Augmented Sampling (VAS) offers an efficient and powerful solution for adapting and personalizing LLMs. It overcomes the instabilities of existing RL algorithms, achieving both high performance and computational efficiency, supports adaptation of black-box models, and paves the way for the personalized and aligned future of LLMs. |
