PHP - Securing Pages

Hello,

I'm writing an application that will have to interact with my webserver and it will be using php to input data into the database and retrieve from as well. However, I'm not sure what is the best approach on securing my database from people sniffing while using my application. The only thing that I can do that is coming to mind is try to use a unique key as a password and have one of my GET vars be that password, but that is easily sniff-able.

What can I do to secure my database and prevent people from filling up my databases if they sniff out my password key? Is there any kind of encryption I can use that will defeat this?

Hey everyone,

I am new to PHP and I want to learn how to secure a PHP session properly.

I wrote a few lines, but I don't know if it's secure enough.

Code: [Select]
<?php
session_start();

if (isset($_SESSION['exists'])) {
    if ($agent != $_SERVER['HTTP_USER_AGENT']) {
        session_unset();
        session_destroy();
        session_regenerate_id(True);
}
}
else {
    $_SESSION['exists']=1;
    $agent=$_SERVER['HTTP_USER_AGENT'];
    session_regenerate_id();
}
?>

Can anybody help me correct or improve my code?

Thanks in advance.

Hi my website offers the users to buy the videos. But the hackers are stealing my video links through view source. So there any option to hide my video links in view source and firebug etc..My videos are comign from amazon. and we are using JW  Players to play the videos
    The methods i have tried..
    1)Encode and decode the urls still the embed tag displays the complete path in firebug.
    2)Amazon provide signed url(temporary url)-Still have some problem in this..
    3)call the video through ajax call. Still the complete HTML code will be displayed in the firebug.
   
    please check here i have attached the firebug sample how it displays the code. Here we can find the complete video path in file: attribute in embed tag
   
    Is there any to hide the urls

Hi,

I want to secure my AJAX routines which use the POST method. I want to prevent people from posting to my method with their own program/script.

I have read about making a random seed that the server knows to expect from authorized AJAX sources.

What is the basic code for doing this?

Hello, I wish to secure the PayPal form button. As my button is used on a subscription website, I don't want people changing the parameters and code needs to be hidden from peering eyes with firebug for instance.


I have heard that you can pass the data to PayPal be given a CMD URL in return and you simply forward the user to such URL.


Anyone know of this? - or another method?


The button manager is not acceptable as the values will change in the hidden fields.

I am building an e-commerce site and have a security question.

My Payment Gateway has given me "Log-In ID" and "Transaction Key" that I use to log in to their server to submit payments.

What is a *reasonable* way to protect this information?

I have a VPS with root access, although I'm relying on using sFTP and the Plesk Control Panel since I don't know SSH yet.

Can I just store my "Log-In ID" and "Transaction Key" in a php file outside of my Web Root and include it?

Would that be secure enough for now?

Thanks,



Debbie

I've just gotten back into re learning web development, I have created a contact form however my server is forcing me to use SMTP which will require me to have a config include with my details inside. How do I ensure nobody can open the files in the browser? I have heard of putting the files outside of the webroot or using htaccess files however the passive aggressive answers I got from stack over flow didn't tell me HOW to implement them.

The files are
Form.HTML
Bin/config.php
Bin/mail.php

Any help is appreciated.

I tried searching but came up empty handed, hoping you guys can give me some assistance.

I have a login script that I would like to lock down a little from flooding. What is the easiest way to do this? Something that will restrict the IP if the script encounters x amount of failed attempts in x amount of minutes.

Thanks!

If I store a value in a hidden form control, and then use that as a means to pass the value to another PHP script, could that cause any security issues?

Hello everyone,

When I do choose lotto on index.php , I do get the page and also can choose how many roster I want.
But I can't see my lotto results, because it does refresh to the index.php again.
How can I fix this problem ?

this is the code of index.php:
Code: [Select]
<?php
        echo '<table class="achtergrond" border="1">';
        echo '<tr><td colspan="3">';
        /* Keuzelijst tonen */
        echo '<center><form action="'.$_SERVER['php_self'].'" method="POST"><select name="test">';
        echo '<option selected>Kies een formulier</option></center>';
        echo '<option value="1">Lotto</option>';
        echo '<option value="2">Euromillions</option>';
        echo '</select>';
        echo '<button type="submit" name="knop">OK</button>';
        echo '</form>';
        echo '</td></tr>';
            /* Als er op de knop gedrukt is , voer het lottoformulier uit*/
           if(isset($_POST['knop']))
           {
                  echo '<tr><td>';
                  echo $waarde;
                  /* variabel $waarde een waarde insteken via keuzelijst  */
                  switch($_POST['test'])
                  {
                      case 1;
                          include('formulieren/lotto.php');
                      case 2;
                          include('formulieren/euromillions.php');
                  }
                  echo '</td></tr>';
                  echo '</table>';

           }          
        ?>

          switch($_POST['lotto'])
          {
                case 0;
                   $waarde2 = 0;
