In ARP attack, the DDoS agents constantly send a barrage of ARP requests to the gateway, or to a victim computer within the same sub-network, and tie up the resource of attacked gateway or host. In this paper, we set to measure the impact of ARP-attack on resource exhaustion of computers in a local area network. Based on attack experiments, we measure the exhaustion of processing and memory resources of a victim computer and also other computers, which are located on the same network as the victim computer. Interestingly enough, it is observed that an ARP-attack not only exhausts resource of the victim computer but also significantly exhausts processing resource of other non-victim computers, which happen to be located on the same local area network as the victim computer.展开更多
近两年来,分布式拒绝服务(Distributed Denial of Service,DDoS)攻击成为一种日益常见的网络异常流量,它不仅导致被攻击者的网络服务中断,还对电信运营商的IP城域骨干网的安全构成严重威胁。从电信运营商的角度,分析了危害IP城域网安全...近两年来,分布式拒绝服务(Distributed Denial of Service,DDoS)攻击成为一种日益常见的网络异常流量,它不仅导致被攻击者的网络服务中断,还对电信运营商的IP城域骨干网的安全构成严重威胁。从电信运营商的角度,分析了危害IP城域网安全的DDoS攻击特征,在综合考虑攻击特征、技术现状、投资成本的基础上,提出一种容易在IP城域网部署的DDoS攻击检测与封堵方案。试用结果表明,该方案可以显著提高运营商IP城域网在DDoS攻击事件方面的响应处理能力。展开更多
