LLaSM: Large Language and Speech Model
Multi-modal large language models have garnered significant interest
recently. Though, most of the works focus on vision-language multi-modal models
providing strong capabilities in following vision-and-language instructions.
However, we claim that speech is also an important modality through which
humans interact with the world. Hence, it is crucial for a general-purpose
assistant to be able to follow multi-modal speech-and-language instructions. In
this work, we propose Large Language and Speech Model (LLaSM). LLaSM is an
end-to-end trained large multi-modal speech-language model with cross-modal
conversational abilities, capable of following speech-and-language
instructions. Our early experiments show that LLaSM demonstrates a more
convenient and natural way for humans to interact with artificial intelligence.
Specifically, we also release a large Speech Instruction Following dataset
LLaSM-Audio-Instructions. Code and demo are available at

CHAOS: An SDN-Based Moving Target Defense System
Moving target defense (MTD) has provided a dynamic and proactive network defense to reduce or move the attack surface that is available for exploitation. However, traditional network is difficult to realize dynamic and active security defense effectively and comprehensively. Software-defined networking (SDN) points out a brand-new path for building dynamic and proactive defense system. In this paper, we propose CHAOS, an SDN-based MTD system. Utilizing the programmability and flexibility of SDN, CHAOS obfuscates the attack surface including host mutation obfuscation, ports obfuscation, and obfuscation based on decoy servers, thereby enhancing the unpredictability of the networking environment. We propose the Chaos Tower Obfuscation (CTO) method, which uses the Chaos Tower Structure (CTS) to depict the hierarchy of all the hosts in an intranet and define expected connection and unexpected connection. Moreover, we develop fast CTO algorithms to achieve a different degree of obfuscation for the hosts in each layer. We design and implement CHAOS as an application of SDN controller. Our approach makes it very easy to realize moving target defense in networks. Our experimental results show that a network protected by CHAOS is capable of decreasing the percentage of information disclosure effectively to guarantee the normal flow of traffic
