防护说明
CC 防护根据访问特征和连接状态判定恶意行为来阻断黑客的攻击。可根据不同的攻击场景配置相应的防护策略，保证业务稳定。清洗阈值是高防产品启动清洗动作的阈值。
前提条件
1. 您需要已成功购买 DDoS 高防 IP，并设置防护对象。
2. CC 防护当前仅支持域名接入的规则生效。
操作步骤
1. 登录 DDoS 防护（新版）控制台，在左侧导航栏中，单击 CC 防护。
2. 在 CC 防护页面的左侧列表中，选中高防 IP 的 ID 下面的域名。
﻿
3. 在右侧 CC 防护开关及清洗阈值卡片中，单击
﻿
开启CC 防护，当防护开启后必须进行清洗阈值设置否则无法开 CC 防护。
﻿
说明：
CC 防护开关是控制是否启用 CC 防护的总开关，开启后下方的防护策略才能生效。
4. 清洗阈值是高防产品启动清洗动作的阈值，当接入的域名收到的 HTTP 请求超过清洗阈值时，触发 CC 防护。当 CC 防护开启后，业务实例的清洗阈值采用默认值（推荐），并随着接入业务流量的变化规律，DDoS 防护系统将根据 AI 算法自动学习并生成一套专属的默认阈值。同时，您也可以根据实际业务情况自定义清洗阈值。
说明：
自定义具体的阈值可以设置为正常业务峰值的1.5倍。
自定义阈值越小，检测要求越严格。
当清洗阈值低于默认值时，可能存在误杀。当清洗阈值高于默认值时，可能存在透传。推荐开启默认清洗阈值。
