198.44.224.X怎么防止DDoS攻击
DDoS攻击的主要目标是使目标系统对其用户不可用。为此,黑客发送大量虚拟请求,使服务器无法处理它们,结果导致系统崩溃。当处理请求的Web服务器被大量请求淹没并停止运行时。发生这种情况时,尝试访问网站的用户会看到错误提示而不是预期的页面。
为产生DDoS恶意流量,在大多数情况下使用大量受恶意软件感染的网络设备组合在一起形成僵尸网络,该僵尸网络向受害者的IP地址发送多个请求。

一、DDoS攻击是什么样的
DDoS攻击方法各不相同,但都会导致合法流量的流失,换句话说,即是用户流失。因此,它常常被用作不公平竞争的工具。在线电商平台和游戏、电子支付系统是遭受DDoS攻击的主要受害者。
因此,如何停止DDoS攻击的问题日益受到关注。在保护网站方面,从托管网站的IDC 运营商处寻求帮助似乎是合乎逻辑的。然而,对于许多具有廉价服务的IDC公司而言,他们更愿意直接禁用、丢弃被DDoS攻击的网站,而不是找到防御DDoS的方法,同时保持网站运行。
我们应该做什么?有两种解决方案:自我实施的措施和针对DDoS的专业保护。请注意,不存在防御DDoS攻击的通用方法,因为黑客一直在寻找新的漏洞和克服保护系统的方法。但是,网站管理员应该知道简单有效的技术。它们将有助于实施针对最简单形式的DDoS攻击的防护。
二、DDoS防护服务
如果您想保护您的在线业务,您应该考虑专门针对DDoS攻击的服务,例如高防服务器。
为什么要获取专业的DDoS防护服务?为什么需要高防服务器?专业的高防服务器供应商有自己的或租用的流量清洗中心,配备特殊的异常流量过滤设备。受保护的高防服务器的流量首先在那里发送,在分析并检查攻击之后,然后将其路由到目的地地址。现代技术允许以如此快的速度执行数据交换和过滤过程,使得用户甚至不会注意到任何延迟,这些延迟不是以秒为单位测量的,而是在CPU周期中测量的。
客户端流量由保护服务提供商的工程师实时监控,并且他们可以随时调整过滤规则,包括为新类型的DDoS攻击手动配置封堵模式。
流量重定向可以通过不同方式实现:
• 使用代理(无需转移受保护的系统)
• 配置虚拟隧道(通过IPIP或GRE),
• 通过交叉连接(受保护的基础设施和洗涤设施之间的电缆连接)。
三、怎么选择DDoS防护服务
应该使用什么DDoS防护服务?它取决于受保护的业务场景。对于网站,最合适的解决方案是使用保护代理或受保护的高防服务器。无论如何,DDoS保护提供商必须拥有庞大的通信渠道来接收大量流量,因为网络攻击的规模几乎呈指数增长,并且已经有1Tbps的DDoS攻击。因此,在选择高防服务器或其他DDoS保护供应商时,您需要了解他们的技术能力。
一个显著的优点是具有位于不同国家的过滤设备,因为这允许在距离其源最近的距离处接收和处理流量,从而将等待时间减少到最小。此外,多个点之间的流量分配允许减少每个过滤节点及其设备的总负载,这也将增加网络稳定性。
