im assusing your talking about php with apache if so use php_admin_value openbase_dir, i would also use php-exec-dir patch, to block all executables so they cant jump outside to other dirs with normal binarys.

However, when browsing the web, I found an article which said that "it requires an expert to lockdown php" (Sorry, but I can't quite recall the URL). While I am not a novice, I am defintely not an expert either - expecially on security issues. So, I'd like to ask the members of this list - how difficult is it to secure php ? Do you really need a security "expert" to do this ? P.S. The few hundred students mentioned above are IT students ;-)I think one thing worth mentioning is that in *most* PHP installations, the PHP code will be executed as the web server user. This means that the several hundred IT students will be able to read each other's code and write to each other's datastores. Most students will have to chmod a+w any files or directories that will be modified by their PHP code. There are several ways around this, but it does take more configuration and security smarts to implement. This "vulnerability" (if you can call it that) exists in just about every multi-user web system out there, so it's probably worth your time to investigate different security mechanisms. __________________________________ Do you Yahoo!?
