“僵尸网络”对网络安全的威胁与防范措施

"僵尸网络"攻击者们采取各种途径进行僵尸程序传播,网络上的主机一旦感染了"僵尸网络"病毒将会接受攻击者的控制信道指令,在攻击者的控制下不断地进行传播,从而组成僵尸网络。僵尸网络对网络安全产生了巨大的威胁。本文将从僵尸网络的概述出发,分析僵尸网络传播的方式和僵尸网络的危害性,从而提出相应的防范措施。     

基于重组的半分布式僵尸网络抗打击技术

僵尸网络防御技术的不断涌现对僵尸网络生存能力提出了严峻的挑战,为了改善僵尸网络的生存能力,从攻击者角度提出一种适用于半分布式僵尸网络的基于重组的抗打击技术。通过对僵尸网络生存状态的感知和对存活节点的探查,实现了半分布式僵尸网络在遭受严重打击导致拓扑结构破碎情况下,寻回存活节点并将其重组为新的僵尸网络。通过实验验证了该技术的有效性,证明其能够有效增强半分布式僵尸网络的生存能力     

动态僵尸网络模型研究

现有的僵尸网络技术和检测方法通常局限于某种特定的僵尸网络。为提高僵尸网络的隐秘性,提出了一种动态僵尸网络模型,利用有向图进行描述,可以表示不同类型的僵尸网络。对模型的暴露性、可恢复性和可持续性等动态属性进行量化分析,给出了一种僵尸主机主动丢弃原则。实验结果表明,提出的方法可以有效降低僵尸网络检测率,提高僵尸网络的可持续性和可恢复性。

僵尸网络中的关键问题

僵尸网络是一种复杂、灵活、高效的网络攻击平台,在互联网中分布非常广泛.僵尸网络使攻击者具备了实施大规模恶意活动的能力,如发送垃圾邮件、发动分布式拒绝服务攻击等.由于其危害日益严重,僵尸网络已经成为网络安全研究的热点之一.但是近年来,僵尸网络新的发展、变化,突破了以往对僵尸网络的认知.文中分析僵尸网络的现有研究,对僵尸网络进行了重新定义,并从网络结构、网络独立性和信息传递方式等角度对僵尸网络的类型进行了划分;然后,梳理了僵尸网络检测技术、测量技术和反制技术等方面的工作;最后,给出了僵尸网络的演化趋势和未来研究方向.     

浅谈僵尸工具分析方法

网络上黑客泛滥,他们利用各种各样的僵尸工具控制僵尸（被植入控制程序的计算机）从而形成僵尸网络,对网络进行恶意行为,包括对某目标进行分布拒绝服务（DDoS）攻击,发送大量垃圾邮件,窃取密码,用户信息等重要资料。因此,不论是对网络安全运行还是用户数据安全的保护来说,僵尸网络都是极具威胁的隐患。僵尸网络也是目前网络信息安全重点关心的一个话题。对僵尸网络和僵尸工具分析方法进行了介绍,并对网络上流行的僵尸工具的特征进行了分析统计,有助于发现网络上的僵尸网络及潜伏的黑客。

A digital revolution: Comparison of demographic profiles,attitudes and gambling behavior of Internet and non-Internet gamblers

Internet gambling is one of the fastest growing sectors of e-commerce and rapidly growing as a mode of gambling. Although Internet gambling is characterized by high levels of customer choice, little is known about Internet gamblers or their engagement with Internet and non-Internet forms of gambling. Regulators are struggling to respond to Internet gambling given that little is known about the impact of this mode of gambling on the existing gambling market, who is gambling online and how. This paper presents one of the largest studies of Internet gambling; an online survey completed by 6682 Australian gamblers. Results show that Internet gamblers are a heterogeneous group, although there is a tendency for Internet gamblers to be male, have high incomes and be well educated. Internet gamblers have more positive attitudes towards gambling and are more highly involved gamblers, engaging in many different gambling activities in both online and offline forms. However, a proportion of Internet gamblers prefer the privacy and anonymity of Internet gambling and do not like land-based venues, suggesting that Internet gambling is creating a new market of gambling customers. Understanding the impact of this new mode of gamblers on existing gamblers and new players is important to contribute to the appropriate regulation of this activity.

Internet use and developmental tasks: Adolescents’ point of view

This study explored adolescents’ opinions about how Internet use supports the achievement of their developmental tasks. Qualitative data were collected in focus groups interviews with 127 Italian Internet users (11–20) attending middle and high schools. Discussions were recorded, transcribed and analyzed using content analysis. Results showed that the Internet plays important functions in identity formation, personal autonomy, and relationships outside the family. It allows teens to develop their own interests, to identify with others and, at the same time, differentiate from others. The Internet is also an arena in which adolescents develop and practice autonomy. The Internet can be a source of conflict with parents, because of parents’ concerns about Internet use. However, the Internet can also be a meeting ground with parents. Finally, participants indicated the Internet is used to form close relationships with peers. Gender and age differences are discussed. Although the study is cross-sectional and relies only on adolescent report, findings illustrate how the conceptual framework of developmental goals may be helpful for understanding how the Internet can affect adolescents’ lives.

An Empirical Study of Use Contexts in the Mobile Internet,Focusing on the Usability of Information Architecture

The mobile Internet—accessing the Internet via a mobile device—has become quite popular recently. The mobile Internet is mainly different from the stationary Internet because it may be used in various contexts, whereas the stationary Internet is mostly used in pre-determined environments. However, it is unclear when the mobile Internet is used most frequently, and in what context it is most useful. A greater understanding of the contexts for using the mobile Internet will relieve usability problems that mobile Internet users often encounter.This paper proposes a conceptual framework of use contexts, which includes various facets of contexts related to the mobile Internet. It then presents the results of an exploratory study in which the use contexts for the mobile Internet and corresponding usability problems have been empirically monitored. The results indicate that use of the mobile Internet is heavily clustered around a few key contexts, rather than dispersed widely in diverse contexts. Moreover, different contexts are found to cause different kinds of usability problems. The paper ends with theoretical and practical implications of the study results.

Measuring Internet usage: The Israeli case

The article describes two instruments for measuring Internet Usage and the changes in subjects’ Internet usage following a controlled intervention. It focuses on the use of usage and lack of usage for measuring the digital gap. The “digital gap” is defined as the gap between individuals with and without access to technology (telephones, computers, Internet access) and related services. Since its emergence, the Internet has become the most important form of information and communication technology (ICT).The goal of the present research was to develop ways of measuring Internet usage for different segments of the Israeli population (it can also be used to measure Internet usage outside Israel). For the past few years, the Israeli government has sponsored programs designed to increase Internet usage in specific segments of the Israeli population. Some of these programs have been “controlled programs”. Controlled Internet Usage Programs are planned and monitored programs, which use research methods to discover whether they have increased Internet usage and changed Internet habits.The population of Internet users in Israel is presently 45.8% (compared with 68.2% in the US population). The past 5 years has witnessed a significant rise in the number of Internet users in the West in general and in Israel specifically: an increase of 152% in the number of Israeli households connected to the Internet during the period 2000–2005.However, large differences are apparent between the stronger and weaker sections of the Israeli population where the Internet is concerned, and controlled intervention is therefore a very important means of reducing these discrepancies.The present article describes two measurement instruments: the first instrument examines on-line proficiency, while the second determines patterns of Internet use and the status of respondents’ “Internet awareness”.The instruments were built to determine the reduction in the digital divide associated with Internet usage following controlled intervention, and the population's Internet usage status before and after intervention. The difference between the two measurements represents the increase or decrease in Internet usage.These two instruments may be used by agencies making decisions about resource disbursement to reduce the digital divide in a variety of populations.
