How To Secure Apache Proxy Server (mod_proxy)

Posted on in Categories , , , , , , , , , last updated May 31, 2008

Q. I’ve proxy (mod_proxy) enabled for Apache under Debian Linux 4.0 server. I’d like to use this to improve performance, but I don’t want an open proxy that can be used by anyone on the Internets? How do I secure my proxy as limiting access is essential as I’m using a forward proxy?

A. You can easily restrict proxy access to single domain, IP or subnet.

Forward proxy example

You can control who can access your proxy via the <Proxy> control block. Use configuration as follows to allow access from your-domain.com only:

<Proxy *>
   Order deny,allow
   Deny from all
   Allow from your-domain.com
</Proxy>

OR allow access from 10.1.5 only

<Proxy *>
   Order deny,allow
   Deny from all
   Allow from 10.1.5
</Proxy>
