Traditional tools often struggle to efficiently\u0000process the vast volume and variety of data acquired during DF investigations\u0000and Incident Response (IR) processes. This paper presents a novel framework,\u0000GenDFIR, that combines Rule-Based Artificial Intelligence (R-BAI) algorithms\u0000with Large Language Models (LLMs) to advance and automate the TA process. Our\u0000approach consists of two main stages (1) We use R-BAI to identify and select\u0000anomalous digital artefacts based on predefined rules. (2) The selected\u0000artefacts are then converted into embeddings for processing by an LLM with the\u0000help of a Retrieval-Augmented Generation (RAG) agent. The LLM consequently\u0000leverages its capabilities to perform automated TA on the artefacts and predict\u0000potential incident scenarios. To validate our framework, we evaluate GenDFIR\u0000performance, efficiency, and reliability using various metrics across synthetic\u0000cyber incident simulation scenarios. This paper presents a proof of concept,\u0000where the findings demonstrate the significant potential of integrating R-BAI\u0000and LLMs for TA.

Aref","doi":"arxiv-2409.02088","DOIUrl":"https://doi.org/arxiv-2409.02088","url":null,"abstract":"Disaggregating memory from compute offers the opportunity to better utilize\u0000stranded memory in data centers. It is important to cache data in the compute\u0000nodes and maintain cache coherence across multiple compute nodes to save on\u0000round-trip communication cost between the disaggregated memory and the compute\u0000nodes. However, the limited computing power on the disaggregated memory servers\u0000makes it challenging to maintain cache coherence among multiple compute-side\u0000caches over disaggregated shared memory. This paper introduces SELCC; a\u0000Shared-Exclusive Latch Cache Coherence protocol that maintains cache coherence\u0000without imposing any computational burden on the remote memory side. SELCC\u0000builds on a one-sided shared-exclusive latch protocol by introducing lazy latch\u0000release and invalidation messages among the compute nodes so that it can\u0000guarantee both data access atomicity and cache coherence. SELCC minimizes\u0000communication round-trips by embedding the current cache copy holder IDs into\u0000RDMA latch words and prioritizes local concurrency control over global\u0000concurrency control. We instantiate the SELCC protocol onto compute-sided\u0000cache, forming an abstraction layer over disaggregated memory. This abstraction\u0000layer provides main-memory-like APIs to upper-level applications, and thus\u0000enabling existing data structures and algorithms to function over disaggregated\u0000memory with minimal code change. To demonstrate the usability of SELCC, we\u0000implement a B-tree and three transaction concurrency control algorithms over\u0000SELCC's APIs. Micro-benchmark results show that the SELCC protocol achieves\u0000better performance compared to RPC-based cache-coherence protocols.\u0000Additionally, YCSB and TPC-C benchmarks indicate that applications over SELCC\u0000can achieve comparable or superior performance against competitors over\u0000disaggregated memory.","PeriodicalId":501168,"journal":{"name":"arXiv - CS - Emerging Technologies","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142213907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In\u0000order to fully leverage the capabilities of this new generation of ANNs,\u0000optimization algorithms that take into account hardware limitations and\u0000imperfections are necessary. Photonics represents a particularly promising\u0000platform, offering scalability, high speed, energy efficiency, and the\u0000capability for parallel information processing.
