Security Mod

[pein87]

I am planning to work on a secrity mod for vbulletin but i wnted to get some input from more seasoned dev's here on vb. My plan is to create a file locking system by using the

$lockFileCommand = flock($showthread, $lockWrite && $lockRead);

but i`m not sure if this method wold really work. I was going to save the file locking commands under the variables $lockWrite and $lockRead to make it easier to use them in my scripts. My question is would this work to lock the files and give only the vbulletin files access to read and write them. I was going to do a similar deal to the

define('THIS_SCRIPT', 'showthread');

but instead use

define('VB_SCRIPT', 'showthread');

and an included file to each script so that if the above is defined it can read and even write to the other files that have it defined. I`m wondering would i be wasting my time doing this or would it actually work on preventing people from hacking sites?

please voice your input on this.
