Security is by far the most important aspect that any webmaster should consider for long term website success. A lot of open source and commercial tools are available to scan your website for vulnerabilities. If you are looking for an efficient, powerful, fast and free tool, then you might need to give “Skipfish” a try.

If you are a web developer or administrator, aside from administering your web server, you should also be administering your MySQL database in terms of security. This database is open source and is commonly used with the PHP web server scripting language; tons of useful applications are being developed with this kind of setup. This is good, but it opens up issues, which we'll discuss here along with their solutions.

PHP encryption is a method of obfuscating scripts in such a way that it offers additional protection and prevents unauthorized editing of the scripts. This article discusses both encryption and decryption.

Microsoft is releasing a security patch for Visual Studio and another "moderate" rated patch for IE for almost all versions. The patches are must-haves for developers that use Visual Studio and any internet explorer users.

Recent attacks against the United States IT security infrastructure has officials worried that, over the next decade, qualified cyber-security personnel will be at a premium; and a shortage. The question is: how does the USA plan to lure and keep top tech talent to secure and protect the national information infrastructure?

If you're trying to keep your LAN secure, sometimes it helps to think like a cracker. This article shows you how to scout out a LAN, and how malicious hackers get around security.

This is the last part of a three-part series covering encryption and decryption, with a focus on the algorithms used. If you have missed either the first or second part, I encourage you to check them out before reading this part.

This is the second part of a series covering cryptography algorithms. If by any chance you have missed its first part, I urge you to check it out right now. It is called "An Introduction to Cryptography." In order to understand this article, it is crucial to grasp the concepts explained in that part.

In the last few decades the science and study of cryptography has earned an outstanding reputation due to its insane applicability and efficiency. Cryptography is the science of message secrecy. Its importance is easily explicable -- it is used everywhere: online purchasing, secured money transfers, cellular phones, broadcast of TV channels, emails, confidential data, and so forth. Our life would be quite different without cryptography.

When we talk about “security” we know what we want, but describing it and making it happen can be different matters altogether. Network security has a natural conflict with network connectivity. The more an autonomous system opens itself up, the more risk it takes on. This, in turn, requires that more effort be applied to security enforcement tasks. This article is chapter eight of the book, Cisco: A Beginner's Guide, third edition, by Anthony Velte and Toby Velte (McGraw-Hill/Osborne, 2004, ISBN: 0072256354).

If you want to run a business with a website, security must be high on your list of important matters to get right up front. In this article, you will learn about Internet-based network security assessment and penetration testing, which can help you determine your website's risk of being successfully attacked -- and what to do to fix any problems. It is taken from chapter one of the book Network Security Assessment by Chris McNab (O'Reilly, 2004; ISBN: 059600611X).

If you have ever wondered how to configure and run a secure open source firewall, look no further. This book excerpt is from chapter three of Open Source Security Tools by Tony Howlett, ISBN 0321194438, copyright 2004.

In this second of a three-part series covering threats to computer security, we focus on attacks that are more specifically directed against a particular person or company.

It's no secret that any computer connected to the Internet faces a wide array of security threats. These days, however, a business needs to be connected to the Internet just to do business. What can you do? Keep reading to learn more about risks you take, and what you can do to protect yourself and your company.

Many of us who use use security products on our computers religiously are bewildered to find that we still get infected with malware. How does this happen? No matter what we do, our computers are constantly in touch with the vectors that carry malicious software. Thomas Greene explains what this means, and what we can do about it.
