    Hello guys i am looking for a php security expert i know this is probably the wrong place to post this, but i know for a fact alot more people will view it here than if i post it in the "buy/sell/trade/" section.

    I need someone to look though my script and make sure its all secure, unhackable and not exploitable.

    I have been thinking along these lines as well.

    Is there a site that has some newbie PHP security info? I want to make sure that my new forum doesnt get hacked.

    A few tips:

    Don't trust user input - especially when used in SQL queries, the most common exploits are SQL injections, always quote variables in queries (even if they don't need to be) use mysql_escape_string, and cast variables to whatever the variable type _should_ be ( e.g. $int_for_db = (int)$var; )

    Don't use super globals - this is only a problem if you're running a old version of php, or have enabled them in php.ini

    Don't include files based on user assigned variables - this can be done safely, but it's easier to just avoid it completely.

    Patch your system, and lock it down with a firewall - More general security advice, but most hacks are from exploits released in the wild targeting unpatched systems. Also, you should disable _all_ unused services, or at least block them on the public interface using iptables (or on an IIS server, whatever firewall is available)

    The most important point is not to trust the users, please assume all users are malicious, and want to 0wn you.

    Guys, this info is great, but he's looking for an audit, not an advice (correct me if I'm wrong, TheWebJunkie).

    Can you post your code? You want this private?

    I've got plenty of php forms that I wrote and rewrote for other folks. My forms have been fine. The other folks had kiddie scripters playing havoc on um. That no longer happens. ;)

    The poster above laid it out pretty good for ya.

    How many lines of code and how many form and url variables we taking? Holler if I can help.

    WebJunkie, I would advise you to not post your scripts. If they do contain exploitable code, posting on a public forum is _not_ a good idea.

    Just like the man said, he's looking for an audit. That is, if you consider yourself a security expert and want to make a few bucks, PM him. If you agree on details, he will ship you the code in a secure way :D

    First, start with your server - is that as secure as it can be ??
    It doesn't matter a toss if your script is secure if the underlying server isn't.
    I don't specialize in security, so I'm not the best person to carry out a security audit. But last time I paid for one to be done, it cost a quite considerable amount.
    As I said above, your actual script is only part of the equation. You need to take everything into account.

    Also, If you're on a shared hosting service you need to audit every other site on that server.

    Seems like an ordinary small-size company that doesn't have much experience. Their security tips are lame, just as their online tools or the Papers section. There's nothing on the website that would indicate that they know what they are doing.

    Dear Sir,
    The main security issue in an php web application should be SQL injection and XSS attack, you should correct php script, as well as change the server settings.

Once I started to work, I will keep you posted by using a daily summary to report work progress. I also can help you with Server clustering, Software localization including Simplified Chinese and Traditional Chinese etc. Look forward to working with you! For more detailed info about my profile, please contact me at celecn AT gmail DOT com!

    Thanks,
    David
