我在一个网站上做自由职业者,该网站在我工作之前被黑了 3 次。
我现在正在工作,经过一些更改后,我将上传我使用这些步骤来确保安全。其他一些帮助完整的提示将不胜感激。
我认为服务器有问题,因为某些端口不安全。而且我无法找到并与服务器管理员沟通。
我想从黑客攻击中创建完全安全的网站:
我使用这两个函数来防止 sql 注入。
function escape($string) {
if(get_magic_quotes_gpc()) $string = stripslashes($string);
return mysql_real_escape_string($string);
}
还有一些时间使用:
function remove_spc_chr($str){
$str=trim($str);
$arr=array('%','$','/','\\','*','+','=','\'','"','#','@','(',')','^','~','`','&',
',',';','\'','?','<','>','!','{','}','[',']');
$str=str_replace($arr,'',$str);
$str=strip_tags($str);
return $str;
}
我将这段代码用于 htaccess 安全性:

我在查询中使用之前检查变量是否正确。
如果有安全步骤对我有帮助吗?
如果有问题或任何漏洞,请回答安全步骤。
