QPS和请求次数有什么区别? QPS(Queries Per Second)即每秒钟的请求量,例如一个HTTP GET请求就是一个Query。请求次数是间隔时间内请求的总量。 QPS是单个进程每秒请求服务器的成功次数。 QPS = 请求数/秒(req/sec ) “安全总览”页面中QPS的计算方式说明如表1所示。
加3组条件,多组条件之间是“或”的关系,即满足其中1组条件时,本条规则即生效。 条件设置参数说明如下: 字段 子字段:当字段选择“IPv4”、“IPv6”、“Params”、“Cookie”或者“Header”时,请根据实际使用需求配置子字段。 须知: 子字段的长度不能超过2048字节。
开源组件Fastjson拒绝服务漏洞 2019年09月03日,华为云安全团队检测到应用较广的开源组件Fastjson的多个版本出现拒绝服务漏洞。攻击者利用该漏洞,可构造恶意请求发给使用了Fastjson的服务器,使其内存和CPU耗尽,最终崩溃,造成用户业务瘫痪。目前,华为云Web应用防火墙(Web

哪些情况会造成WAF配置的防护规则不生效? 域名成功接入WAF后,正常情况下,域名的所有访问请求流量都会经过WAF检测并转发到服务器。但是,如果网站在WAF前使用了CDN,对于静态缓存资源的请求,由于CDN直接返回给客户端,请求没有到WAF,所以这些请求的安全策略不会生效。 WA

配置示例 添加防护域名时,可根据您的业务场景参考以下示例进行配置。 示例一:80/443端口业务防护配置 示例二:客户端请求转发到不同的源站服务器 示例三:同一域名对应不同的防护端口 示例四:不同访问模式的协议配置规则 示例一:80/443端口业务防护配置 配置场景:需要防护域名对应的80或者443端口的业务。
如何解决网站接入WAF后程序访问页面卡顿? 问题现象 网站接入WAF后程序访问页面卡顿。 可能的原因 一般是由于您在服务器后端配置了HTTP强制跳转HTTPS,在WAF上只配置了一条HTTPS(对外协议)到HTTP(源站协议)的转发,强制WAF将用户的请求进行跳转,所以造成死循环。
