G6 Firewall 可以转换为在 NGINX 上使用吗？

Question

我是 G6 防火墙（以前的 G5）htaccess 规则的忠实粉丝。我想知道将其转换为与 NGINX 一起使用是否可能，以及是否有益？可以在此处找到源文章：https://perishablepress.com/6g/。如果可以重写它，你会提供 NGINX 等效规则集吗？我认为这对很多开发人员都有帮助。

这是原始的 .htaccess 规则：

## Add here all user agents that are to be blocked.   
map $http_user_agent $bad_bot {
    default 0;
    "~*([a-z0-9]{2000})"    1;
    ~*(archive.org|binlar|casper|checkpriv|choppy|clshttp|cmsworld|diavol|dotbot|extract|feedfinder|flicky|g00g1e|harvest|heritrix|htmlparser|libwww|httrack|kmccrew|loader|miner|nikto|nutch|planetwork|postrank|purebot|pycurl|python|seekerspider|siclab|skygrid|sqlmap|sucker|turnit|vikspider|winhttp|xxxyy|youda|zmeu|zune) 1;
}

## Add here all referrers that are to blocked.
map $http_referer $bad_referer {
   default 0;
   "~*([a-z0-9]{2000})"    1;
    ~*(semalt.com|todaperfeita) 1;
}

# query strings that should be blocked
map $query_string $bad_querystring {
    default 0;
    ~*(eval\() 1;
    ~*(127\.0\.0\.1) 1;
    "~*([a-z0-9]{2000})" 1;
    "~*(javascript:)(.*)(;)" 1;
    ~*(base64_encode)(.*)(\() 1;
    ~*(GLOBALS|REQUEST)(=|\[|%) 1;
    ~*(<|%3C)(.*)script(.*)(>|%3) 1;
    ~*(\|\.\.\.|\.\./|~|`|<|>|\|) 1;
    ~*(boot\.ini|etc/passwd|self/environ) 1;
    ~*(thumbs?(_editor|open)?|tim(thumb)?)\.php 1;
    ~*(\'|\")(.*)(drop|insert|md5|select|union|concat) 1;  

}

map $request_uri $bad_request {
   default 0;
   "~*([a-z0-9]{2000})"  1;
   ~*(https?|ftp|php):/  1;
   ~*(base64_encode)(.*)(\()  1;
   ~*(=\\'|=\%27|/\\'/?)\.  1;
   "~*/($(\&)?|\*|\"|\.|,|&|&amp;?)/?$"  1;
   ~*(\{0\}|\(/\(|\.\.\.|\+\+\+|\\"\\")  1;
   "~*(~|`|<|>|:|;|,|%|\|\s|\{|\}|\[|\]|\|)"  1;
   ~*/(=|$&|_mm|cgi-|etc/passwd|muieblack)  1;
   "~*(&pws=0|_vti_|\(null\)|\{$itemURL\}|echo(.*)kae|etc/passwd|eval\(|self/environ)"  1;
   ~*\.(aspx?|bash|bak?|cfg|cgi|dll|exe|git|hg|ini|jsp|log|mdb|out|sql|svn|swp|tar|rar|rdf)$  1;
   ~*/(^$|(wp-)?config|mobiquo|phpinfo|shell|sqlpatch|thumb|thumb_editor|thumbopen|timthumb|webshell)\.php  1;
}

map $request_method $not_allowed_method {
  default 0;
  ~*^(connect|debug|delete|move|put|trace|track) 1;
}

然后在服务器指令中添加这个

server {
  ...


  if ($bad_bot) { return 444; }
  if ($bad_referer) { return 444; }
  if ($bad_querystring) { return 444; }
  if ($bad_request) { return 444; }
  if ($not_allowed_method) { return 405; }

  ## Filesystem root of the site and index.
  root /home/$DOMAIN/public;
  index index.php;

  ...

}
