端口反弹型木马通信技术研究及防范措施

端口反弹型木马(Port Recall Trojan Horse)是一种新型的特洛伊木马(Trojan Horse),它不仅能够穿透防火墙,而且还可通过HTTP、SOCKS4/5代理,甚至还能访问局域网内部的没有公共IP的电脑,如用NAT透明代理和HTTP的GET型代理等的局域网,还可能入侵像拨号上网、ISDN、ADSL等的主机,给现有的计算机网络会带来了更大的危害。论文介绍了传统型特洛伊木马的通信原理和端口反弹型木马的通信技术,最后提出了对于端口反弹型木马的防范措施。     

基于内核入侵的木马设计与实现

通过内核入侵是木马入侵Linux系统的一种重要形式,其原理是利用Linux内核提供的机制来实现木马的各种功能,主要是通过内核编程来实现。本文重点研究了内核入侵的两种方法:直接对内核源代码进行修改,利用Linux的模块机制。最后在此基础上完成了一个基于内核入侵的木马设计与实现。     

Predictors of race-day jockey falls in jumps racing in Australia

Thoroughbred jumps racing jockeys have a fall rate greater than their flat racing counterparts. Previous studies have focused on factors that contribute to falls by horses but, to date, there has not been a study of risk factors for falls to jockeys in jumps races. Data on race-day falls were extracted from stipendiary stewards reports lodged with Principal Racing Authorities following each race meeting. Denominator data were provided by Racing Information Services Australia on races conducted from August 2002 until July 2009. Univariable and multivariable analyses, estimating incidence rate ratios, were conducted using Poisson regression. In multivariable analysis in hurdle racing, important predictors of falls were higher club level, larger field size, greater prize money, provisionally licenced jockeys and older jockeys. There were significant interactions between jockey licence and prize money; jockey age and previous rides this meeting; race grade and race distance; horse age and field size; and club level and field size. In steeplechase racing, important predictors were type of jump with lowest fall rates in races over Mark III jumps compared to standard fences, provisionally licenced jockeys, jockeys having had previous rides at a meeting, and larger field size. There were significant interactions between the number of previous starts by the horse and field size; race distance and prize money; and race distance and previous rides this meeting. This study has identified factors for falls in jumps racing that could form the basis for targeted strategies to improve occupational health and safety standards.
