# Check.

1 . [L7 (Cookie Based Protection)](https://github.com/theraw/The-World-Is-Yours/blob/master/static/nginx.conf#L15-L42) AND [Replace "proxy2.dope.. links with yours click here to find aes](https://github.com/theraw/The-World-Is-Yours/tree/master/static/vhost) which should be stored on a external link or in a place where L7 is disabled because it will not work if you put it in main site dir!.

2 . [Auto Ban System](https://github.com/theraw/The-World-Is-Yours/blob/master/iptables/jail.local#L105-L111) based on [Connection for ip](https://github.com/theraw/The-World-Is-Yours/blob/master/static/nginx.conf#L72-L73)

3 . [Auto Ban 444 Reqs](https://github.com/theraw/The-World-Is-Yours/blob/master/iptables/jail.local#L113-L118) A day i've been under attack of multiple proxies, and even after they got banned they still was keep trying the same thing so when you ban someone when that ip tries to access your website that request will not go on `error.log` but in `access.log` so i created this rule to ban with iptables every request who have stauts `444` so nginx will not have to handle those.

4 . [Kernel Settings](https://github.com/theraw/The-World-Is-Yours/blob/master/static/sysctl.conf#L1-L34)

5 . [Naxsi Rules Included](https://github.com/theraw/The-World-Is-Yours/blob/master/static/nginx.conf#L118)

6 . [Example of Naxsi](https://github.com/theraw/The-World-Is-Yours/blob/master/static/vhost/default#L22-L29)

7 . [Check Iptables rules](https://github.com/theraw/The-World-Is-Yours/blob/master/iptables/rules) It will not be automatically enabled, because this changes based on providers in ovh it work in azure it doesn't work. so you need to manually activate iptables!

8 . ModSecurity is not loaded. However you need to set it up by yourself. you have a folder `/nginx/modsecurity/`
which ModSecurity rules are stored, open `/nginx/modsecurity/modsecurity.conf` add those

```bash
Include crs-setup.conf
Include rules/*.conf
```
ModSecurity is by default enabled as "detect only" you can turn it on always by doing this

```bash
SecRuleEngine On
```

Using modSecurity for your site
```bash
server { 
     ..... 
        modsecurity on;
        modsecurity_rules_file /nginx/modsecurity/modsecurity.conf; 
        location / { 
     ..... 
        } 
}
```
**Careful** Using modsec rules like
```
   location / { 
       modsecurity_rules_file /nginx/modsecurity/modsecurity.conf; 
   } 
```
it means that's enabled just for your main place `/` not for other dirs in your site ex `/admin/` (:


Test it!
`curl 'http://localhost/?q="><script>wanna hack</script>'`
```html
<html>
<head><title>403 Forbidden</title></head>
<body bgcolor="white">
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx</center>
</body>
</html>
```

# Keep In Mind.
The **L7 Protection** is the same way which **cloudflare** have that banner "Under Attack" A.K.A Cookie based authorization. Most of bots from where attacks will come doesn't support cookies so it will fail to access your site. (Test it by yourself to "curl http://yoursite.com" before you activate L7 and after you start L7 so you will understand better.)

The L7 protection is a good thing for your protection. But a very bad thing for your website seo!, As facebook/google/bing and all search engines will not be able to access your website anymore. There is a way to allow them but if you have 1 year free time to find all their ips go and try it. I've been thinking for a "reverse dns" whitelist but haven't done it so as of now it is like this.
