Website Security: PHP and MySQL as a SolutionThe winter of 2004 brought with it a new opportunity for me. I began learning and programming in PHP and MySQL as an independent study and also for my job with both the admissions department and financial aid department of Eastern Washington University. My first bit of programming got off to a great start and it was when I was put in charge of developing a secure website that I began researching the topic of website security. I knew very little about how people hacked into websites to do various illegal activities, so I decided that some of the basic entry points into a website and its server needed to be addressed.
Secure website development is of the utmost importance as the number of websites that provide personalized accounts and utilize cross site information. “When you deploy your application on the Web, it becomes available to everyone” (Kabir 737). In this paper I plan to bring to light some dangerous practices that are being used to attack websites. I will present an example of a practice, present a practical and secure way to handle it and if I have encountered the example in my own code, I will discuss my experiences with it. To differentiate between a normal user and a hacker I will use hacker to mean a user whose intentions are to disrupt the normal running of a website and/or server.
“A supposed group of international hackers declares digital war against the United States directly from their headquarters in Russia”HTML/SQL Laboration 1This laboration is split in two parts, the first part about simple HTML programming and the last about SQL databases, with focus on MySQL databases
Read the HTML tutorial on http://www.w3schools.com adn the MySQL tutorial on http://www.mysql.com/doc/en/Tutorial.html. If you don’t have access to a MySQL database read the examples in the tutorial, these will be a great help when you start to solve the Tasks on the MySQL database. You should also be familiar with the Language Reference section.

Tables are a cornerstone in HTML and a widely used for layout.

This is important when you want to provide visitors with information that is always up-to-date, without hand tweaking a lot of static HTML pages. However, although PHP is easy to use, it includes no general-purpose database access interface. Instead it has a number of specialized ones that take the form of separate sets of functions for each database system. There is one set for MySQL, another for InterBase, and another for PostgreSQL—and others as well.
This wide range of support for different database engines help make PHP popular because it means essentially that no matter which database you use, PHP probably supports it. On the other hand, having a different set of functions for each database also makes PHP scripts non-portable at the lexical (source code) level. For example, the function for issuing a SQL statement is named mysql_query(), ibase_query(), or pg_exec(), depending on whether you are using MySQL, InterBase, or Post-greSQL. This necessitates a round of messy script editing to change function names if you want to use your scripts with a different database engine, or if you obtain scripts from someone who doesn’t use the same engine you do.
In PHP 4 and up, this problem is addressed by means of a database module included in PEAR (the PHP Extension and Add-on Repository). The PEAR DBWriting Applications Using PHPMany developers have learned to use PHP over the years because it’s a good solution for creat- ing Web pages and the price is right. The PHP acronym is like many other new acronyms for the Internet—the acronym is recursive (refers back to itself). PHP stands for PHP Hypertext Processor. This general-purpose HTML scripting language works much like ASP (see Chapter 6) or other page description languages you might have used. Essentially, you mix HTML with scripting information. When the PHP process sees HTML, it sends the text directly to the user. It processes any scripting information, and passes the resulting HTML to the user as well.
This chapter helps you discover how PHP works with Amazon Web Services. I’m assuming that you already know something about PHP, but the first two sections provide some suggestions on how to learn more about PHP. Because PHP runs on so many platforms, you’ll also find some suggested resources for getting and installing PHP for your particular server. These instructions might require a little technical knowledge on your part, so make sure you understand what the instructions require before you perform them.
The examples in this chapter show how to use PHP to create an Amazon Web Services application. The first example provides simple instructions for accessing the Web service without any fancy application features. You’ll also find an application that shows how to use PHP with MySQL, an open source database.

CONNECTIONS TO A BUILDING ELECTRICAL SYSTEM Connections for standby power to a building electrical system must be made by a qualified electrician. The connection must isolate the generator power from utility power, and must comply with all applicable laws and electrical codes. Improper connections to a building electrical system can allow electrical current from the generator to backfeed into the utility lines. Such backfeed may electrocute utility company workers or others who contact the lines during a power outage, and the generator may explode, burn, or cause fires when utility power is restored.

Ä CAUTION: Do not add optional hardware devices to your computer until the operating system is successfully installed. Doing so may cause errors and may prevent the operating system from installing properly.
CAUTION: Once the automatic installation has begun, DO NOT TURN OFF THE COMPUTER UNTIL THE PROCESS IS COMPLETE. Turning off the computer during the installation process might damage the software that runs the computer. 1.1 Microsoft Windows 98/Me/XP The first time the computer is turned on, Microsoft Windows is automatically installed. This takes approximately 10 minutes, depending on the system hardware configuration. At the beginning of the installation process, you are prompted to select the appropriate language for the operating system. Read and follow the instructions that appear on the screen to complete the installation. During this process, do not turn off your computer unless you are directed to do so. If you are installing a SCSI controller into a Windows XP environment the system should recognize the Plug and Play device automatically and prompt you for the proper device driver.

The joke goes, “we build tools as if software were made by people … working together.” As a human-centered effort, we draw from various research fields including human-computer interaction, information visualization, computer-supported cooperative work, and social computing. The central tenet of these fields is that one needs to understand the user in order to design tools to support them. To this end we have initiated a series of investigations to understand software development at Microsoft. Our research builds on a rich history of research into professional software development practices [1, 2, 4, 5, 6, and 7]. This document describes the process we used, what we learned, and directions for future user research.
METHODOLOGY
We performed two surveys and several face-to-face interviews of developers at Microsoft during the summer of 2005. The first survey contained 205 questions asking how developers spend their time, what tools they use, and the severity of various problems they face. We deployed it to 1000 architects, software developers and software test developers randomly selected from the Microsoft address book by job title. We received 157 responses, though the data presented here includes only the 104 responses from the developers.
Next we performed semi-structured interviews with six software development leads and five software developers drawn from our survey respondents. Each was done by two interviewers, who took copious notes. Each interview lasted about an hour.

PageRank is a voting algorithm weighted for importance. The indicators of a Web pages importance is the number of pages that link to a particular page. Messrs. Brin and Page soon added another factor which voted for the importance of a Web page. This idea was the number of people who click on a Web page.
The more clicks on a Web page, the more weight that Web page was given. Over time, still other factors have been added to the PageRank algorithm; for example, the frequency with which content on a page is changed.
