基于进化神经网络的入侵检测模型

当前的入侵检测技术主要有基于规则的误用检测和基于统计的异常检测。本文提出一个基于遗传算法的神经网络入侵检测系统模型，该模型将神经网络与遗传算法结合起来，利用神经网络自学习、自适应的特性，同时克服了神经网络易陷入局部最优，训练速度慢的缺点。该模型具有智能特性，能够较好地识别新的攻击。     

外国人居留证管理的现状及可行性改革思路

现行的外国人居留证件管理体系已难以适应形势的发展和需要,改革势在必行。取消现行大一统居留证模式,改版沿用了近50年的外国人居留证和使用了近20年的临时居留证,以磁卡式与贴纸式替代。是今后居留证体系可行性的改革思路。     

关于修改后刑事诉讼法执行情况的若干思考

The revised Law of Criminal Procedure, of which the key idea is to tighten the restraint on and supervi-sion over public power and protect the private rights effectively, shows the pursuits of refined,...     

Scanning memory with Yara

Memory analysis has been successfully utilized to detect malware in many high profile cases. The use of signature scanning to detect malicious tools is becoming an effective triaging and first response technique. In particular, the Yara library and scanner has emerged as the defacto standard in malware signature scanning for files, and there are many open source repositories of yara rules. Previous attempts to incorporate yara scanning in memory analysis yielded mixed results. This paper examines the differences between applying Yara signatures on files and in memory and how yara signatures can be developed to effectively search for malware in memory. For the first time we document a technique to identify the process owner of a physical page using the Windows PFN database. We use this to develop a context aware Yara scanning engine which can scan all processes simultaneously using a single pass over the physical image.     

Surveillance and identity management: Migrant perspectives on UK Biometric Residence Permits

The identity card for foreign nationals - now known as the Biometric Residence Permit (BRP) - was first introduced in November 2008. Following the May 2010 UK general election, the newly formed Conservative-Liberal Democrat Coalition government announced that the scheme would not be extended to UK citizens. To date, over 300,000 BRPs have been issued to UK foreign nationals - a group of non-EEA migrants that include international students, visiting scholars and entrepreneurs. In this paper, we draw on findings from interviews conducted with policymakers, advocacy groups, Higher Education administrators and foreign nationals - between March and December 2010 - to highlight some policy issues arising from the continued roll-out of the BRPs to this migrant group. We conclude by arguing that, although interviewees raised few objections to the BRPs in principle, cardholders were concerned about being unfairly ‘targeted’ for additional surveillance and remained unclear about the true purpose of the BRP. We identify a number of areas for further policy development.     

从“身份”到“场所”——属人法连结点的历史与发展

属人法连结点的发展大约经历了三个历史阶段:古罗马至19世纪是住所地主义形成时期;19世纪至20世纪中叶是国籍原则与住所地主义的并存时期;20世纪中叶至今是属人法连结点的新发展时期。其中,第二个历史阶段的起点并非是国内学界所公认的1804年《法国民法典》,而应是后来的孟西尼学说。国籍原则衰退后,住所的缺陷也逐渐显现出来。在第三个历史阶段,惯常居所替代了住所,成为属人法连结点在当代的新发展。     

农民集中居住良性推进之程序保障

一些地方政府在以行政力量强势推进农民集中居住的过程中,基本上都是地方政府单方面推进,农民没有知情权,集中居住的相关信息不够公开,甚至有些地方的农民无法获得应有的通知公告、书面协议。地方政府公开农民集中居住决策相关信息的法治价值在于保障农民的知情权,以公民权利制约国家权力,防止地方政府行政权力的滥用和腐败。深化集中居住决策的信息公开,要求地方政府既要公开并提供全面准确的集中居住决策信息,又要通过多种途径为广大农民及时获知集中居住决策信息提供便利。     

关于《暂住证》制度改革的思考与分析

从八十年代开始实行的<暂住证>制度,在市场经济条件下其弊端日益明显,从法理上进行分析存在许多违宪、违法问题:(1)违反了宪法的基本原则;(2)为公民设定了法律之外的义务;(3)违反了行政许可法;(4)侵犯了公民的人身权利和自由.从保障人权的宪法原则出发,应当以<居住证>取而代之.<居住证>的特点:非强制性,非歧视性,权益性.     

Voting for locals: Voters’ information processing strategies in open-list PR systems

While most of the literature on information shortcuts in open-list PR systems focuses on the importance of ballot position effects, the influence of a candidate’s localness has widely been ignored by existing studies. In this paper, I address this research gap and argue that voting patterns in open-list PR systems are more versatile than existing research would suggest. By analyzing a special characteristic of the open-list PR system employed in the parliamentary elections of Hamburg, it is shown that a large portion of voters chooses to vote for local candidates irrespective of the ballot position of the candidate. The paper further controls for factors conditioning the effect and finds that it remains strong even after taking them into consideration. The results have important implications for the representativeness of open-list PR systems, ballot paper design, as well as for our understanding of voters’ decision making process.
