【摘要】 本文分析了当前VoIP系统存在的DoS攻击,对每种攻击行为产生的原因进行了描述,并提出了针对这些DoS的防护措施。本文还对近几年来VoIP的安全漏洞进行了统计和分析,从统计结果中可以看出,在VoIP的漏洞中,与DoS相关的漏洞占了一半以上。本文通过实验室环境下对不同VoIP系统的DoS攻击测试,说明了VoIP DoS攻击的一些特点,并提出了一些安全防护措施。更多还原

【Abstract】 The DoS attacks against VoIP network problem has been analyzed.The Reason for the security problem has been described. Some precautionary measures has been also proposed.We can find that More than half of Security Vulnerabilities of VoIP are DoS attacks by statistical analysis of Security Vulnerabilities Published.Some experiment testing has been done for VoIP security in laboratory. We can find some features of VoIP DoS attacks by the testing experiment data.Some precautionary measures have been proposed for different VoIP system.更多还原
