如何在服务器之间的通信中隐藏 url

Question

Let's suppose I've a critical php script which runs on a server. I want to access that php script from another server. I want to not only hide the communication data between the 2 servers but also the URL in order that each time i call the url it's never the same. What is the best way to achieve this behaviour?

Answer 1

for Hiding Url, url is made up from multiple segments. and we can hide each segment as follow:

lets see the URL itself:

Scheme:://foo@host:port/pathes/querystringKey=val#fragment

so for each section you can hide hide it using an Encoding Mechanism,

By The Encoding i mean, change to something that Eve Couldnot understand what is going on.

The Scheme

can be Encoded When you using a Tunnel . Tunnel is another Protocol for Application Layer Communication which you can send your Actual Link in Tunnels Payload . for Example:

• using ssh for transferring file is uncommon. but you can using that with scp
• using a Proxy which Encrypt HTTP Headers like SOCKS 5
• using a VPN since its Tunnels every packet.

The User

Php scripts are not tend to Authenticate The User with URL User Parameter .

so it will be emitted.

The Host

The Host can be ip and domain. since it will be used by network to route your traffic.

in order to make it hide (deform) you can use a proxy to do that.

if you are worry about intruders finding out the actual Destination Host you can use Onion Routing or Garlic Routing

The Port

its simple as not using Common Ports on Client and Server. like not using 443 for https.

Path

you can use one path like index.php and pass the routing parameters in Http Header. Since Your Payload in Header Encrypted using SSL. you are not worry for that.

but if you are worry about to not have a distinc path. you can make a random path to mislead intruders and just eliminate the random path in Servers Url Rewrire . since you get the actual in Http Header and can Route The Request.

QueryString

Query String can get into Http Header. b not Using Http Get Requests.

Fragment

in PHP Url Interpretation, Fragment Plays no Rule
