国外VPS的nginx防止xss和sql注入的方法:
将以下nginx配置文件代码放入到对应站点的.conf 配置文件server里,重启nginx即可,代码如下:
if($request_method !~* GET|POST){return444;}
#使用444错误代码减轻服务器负载压力
#防止sql注入
if($query_string ~*(\$|‘|�|[+|(%20)]union[+|(%20)]|[+|(%20)]insert[+|(%20)]|[+|(%20)]drop[+|(%20)]|[+|(%20)]truncate[+|(%20)]|[+|(%20)]update[+|(%20)]|[+|(%20)]from[+|(%20)]|[+|(%20)]grant[+|(%20)]|[+|(%20)]exec[+|(%20)]|[+|(%20)]where[+|(%20)]|[+|(%20)]select[+|(%20)]|[+|(%20)]and[+|(%20)]|[+|(%20)]or[+|(%20)]|[+|(%20)]count[+|(%20)]|[+|(%20)]exec[+|(%20)]|[+|(%20)]chr[+|(%20)]|[+|(%20)]mid[+|(%20)]|[+|(%20)]like[+|(%20)]|[+|(%20)]iframe[+|(%20)]|[\<|%3c]script[\>|%3e]|javascript|alert|webscan|dbappsecurity|style|confirm\(|innerhtml|innertext)(.*)$) { return 555; }
