                 What is Cloud computing?

Cloud computing is the use of computing resources like hardware and software which are available on the remote location and accessible over a network.
In cloud computing, the word cloud is used for "the internet" and computing  means " a type of internet-based computing".
Here  in cloud computing there is no any local servers or hardware to handle the application.
         


It should be runs through Interface software.All heavy lifting done by the web based services and the third party services holds all information like :
                             - Software       - Saved data       - Security                                                                              
                                                                       The cloud computing is used in online email services, storing online data.Cloud computing networks are large groups of servers and cloud service providers that usually take advantage of low-cost computing technology, with specialized connections to spread data-processing chores across them.  Virtualization techniques are often used to maximize the power of cloud computing.

Their are different types of cloud are their as below....

1) Public Cloud   : A public cloud can be accessed by any subscriber with an internet connection and access to the cloud space.

2) Private Cloud : A private cloud is established for a specific group or organization and limits access to just that group.

3)Community Cloud : A community cloud is stored among two or more organizations that have similar cloud requirements.

4) Hybrid Cloud : It is essentially a combination of at least two clouds, where the cloud included are mixture of public , private and community.

Some of the advantages of the cloud computing

- Unlimited, everywhere access
- Reduction in hardware and software cost.
- No physical space in office or home.
- Increase the computing process.
- Automatic redundancy.

Some of the disadvantages of the cloud computing

-  Change is hard.
-  Security & privacy
     -- User don't physically have data.
     -- Storage cloud be hacked.
-  Services Live and Die by their security reputation.
- Significally harder to infiltrate these system.

 Today I'm gonna talk about USB Drives.
I'll show you a simple trick to lock your USB drive without using any 3rd party software.
Most of the people doesn't like other people checking their personal files and folder on USB, including me. This insecure situation creates a huge space to theft our personal data by someone. If you use password protection to your USB, you can reduce the data theft.

Lots of USB password protect software available in present market, but you want to pay money to use it for lifetime. If you're using Windows you don't need any software.

Some command line junkies always want the command prompt within easy reach.
So here is the way ...... If you use the command line regularly—for example, to launch Windows Explorer with shortcuts you'd like the command line within easy reach. In fact, you'd like it right on your desktop. XP has no built-in way to do that for you.

               Here is the one Great program called MCL that run as small command line you can put anywhere on your desktop as shown in this figure.
To download : CLICK HERE


Now you would use the normal command line, including any normal switches that you use to launch programs.But MCL does more than just let you enter commands. It includes a number of other goodies that the XP command prompt doesn't, including these:

• It keeps a history of your last 100 commands, so you can easily reenter or edit any commands you've already typed.
• It includes an AutoComplete function that finishes your commands for you.
• It lets you launch URLs directly from the command line. If you type a URL, your default browser will open to that URL.
• It can be minimized to the System Notification area.
• It can be launched with a hot key. The default is Ctrl-Alt-M.

                 As we seen in our previous topic that some of the way to prevent from the SQL injection.
If you have not  read yet then must read that first.... click here 

   Today, I am going to share some tips for PHP developer that how to make secure their site from the SQL injection. There are number of things are their to do, from that one of the things are as below:


Let, see the First one

Suppose, As below is your code:

<?php
 $result = mySql_query('select Text from pages where id=' . $_GET['id']);
echo($result);
?>



As shown in the above code it says that you are selecting the page content which is "Text"  from "pages" in the SQL database, and you are sorting out the right page content with $_GET[''id] and $_GET['id'] is the thing in url...

for e.g. :                http://www.example.com/index.php?id=123

As this code is easily injected by the some one, but if you can do this ...

<?php
$result = mySql_query('select Text from pages where id=' . mySql_real_escape_String($_GET['id']));
echo($result);
?>

Then you are 100 % secure.............. If  you like this post then please share this with your friends &  make aware them too from the SQL injection.
