- What is an open proxy?
An open proxy is a server that acts as an open relay but through ports other than 25;
open proxies provide surrogate (proxy) communication ability to other servers through ports not reserved for normal use.
- Why should I secure my open
proxy?
This is a similar situation to running an open relay:
you are allowing non-paying users on your system to have free rein of your resources.
Most of the open proxy server owners we've worked with weren't aware of their vulnerabilities.
- How do I secure my open proxy?
You can either disable connections to the open ports in question or establish an "access control list" (ACL) for that system, which will allow only authorized users to connect to those ports.
