拒绝服务攻击(Denial of Service Attack,简称DoS攻击)是一种通过耗尽目标系统资源(如带宽、计算能力或内存)使其无法正常提供服务的网络攻击手段。攻击者通常通过发送大量无效请求、恶意数据包或利用系统漏洞,导致合法用户无法访问服务器、网站或网络设备。
在技术实现上,分布式拒绝服务攻击(DDoS)是DoS攻击的进阶形式,攻击者通过控制多个被感染的设备(如僵尸网络)同时向目标发起攻击,显著增强破坏力。例如,2020年亚马逊AWS曾遭受高达2.3 Tbps的DDoS攻击,创下流量规模纪录。
这类攻击的危害主要体现在三个方面:
防御措施通常采用多层防护体系,包括流量清洗、行为分析算法和Anycast网络分发技术。美国国家标准与技术研究院(NIST)在《网络安全框架》中建议,关键系统应部署基于机器学习的异常流量检测系统。企业可通过内容分发网络(CDN)和Web应用防火墙(WAF)缓解攻击影响。
拒绝服务攻击(Denial of Service Attack,简称DoS攻击)是一种通过消耗目标系统资源或利用协议漏洞,使其无法正常提供服务的网络攻击方式。以下是详细解释:
DoS攻击通过向目标服务器发送大量无效请求或恶意数据包,耗尽网络带宽、内存、CPU等资源,或触发系统漏洞,导致合法用户无法访问服务。例如,攻击者可能利用TCP协议漏洞(如SYN Flood攻击)使服务器陷入未完成连接的等待状态,最终资源耗尽。
DoS通常由单一攻击源发起,而DDoS(分布式拒绝服务攻击)通过控制全球分布的“僵尸网络”发起更大规模攻击。例如,DDoS可能同时操控数千台设备向目标发送请求。
