Re: How Secure is a Random URL?

Also remember that just because you have a random URL and you haven't told that URL to anybody, and it is highly unlikely anybody will ranbdomly type that URL, this doesn't make the content safe.

The same website can probably be accessed through the IP number for example. So a systematic crawler would sooner or later find it.

I don't see the link between these two points.

The location of your site is publicly available in DNS, for both the name and the IP address so both are equally visible. Not listing a name may slightly improve security, but may not possible for a hosted solution and doesn't help much as there are bots out there randomly trying IP addresses to find weak machines. This is not the same as the full URL with path.

Most systematic crawlers are web search bots - they follow links, so if your hidden directory isn't linked from anywhere they won't find it.

Any other (malicious) crawler is going to have to simply guess the location - if you have a large random path, it should be as secure as any other large random combination like a username and password, with the advantage that a "page not found" response doesn't advertise itself as a target like a login does.

Protecting your site with HTTPS is mandatory for any real security - which requires the DNS name to be used anyway.

Re: How Secure is a Random URL?

Problem is probably the same one I am facing, certain sites, like dropbox or google docs are blocked from within our companies network. Using your own box will most likely mean that it's not on a blocked list anywhere.

As mentioned earlier, if it's your own box, a simple apache .htaccess file is probably the simplest solution.

Think about adding a robots.txt file to stop the good crawlers from trying to dig about on your site too, which should mean that your documents don't show up in a google search.

Others have mentioned that you would also want to use SSL. Might not be that important to you, but StartSSl are pretty good for free 1 year certificates.

Dropbox link will work from any web browser which can download a file. I guess you need that for your homebrewed solution too.

Here is an example of a troll face I uploaded.
