| | We'll create and discuss a very secure hash-based encryption algorithm. The encryption is performed by using the hash function as a PRNG (Pseudo Random Number Generator). The encryption mode may be CFB or OFB (and NOT ECB). |

| | In this two-part series, I hope to convey several points of attacking the attacker, beating the creator at his own game while owning the malware that you are so accustomed to owning you. This paper is long and skews into a few tangents--Definately not an article for the faint of heart. |

| | Your code (and mine of course) is vulnerable to SQL injection attacks wherever it uses input parameters to construct SQL statements. I can't stress enough how risky this is. As with XSS bugs (see my article on XSS), SQL injection attacks are caused by placing too much trust in user input and not validating and parsing their input. This article will show you many examples of SQL Injection, including a one line command to shut down almost any MS SQL server that does not parse user input! |

| | Viruses have become an accepted part of computing in the modern world. A risk of doing business in a networked environment. It's never nice finding your computer infected with a virus or worm, and yet powering up the virus scanner usually takes care of the problem. That having been said, the virus problem is one that is increasing, and is not likely to go away in the near future. Understanding the common virus can help you combat and defeat even the nastiest of nasties. |

| | Securing your system is easy!? Just use a firewall you can download somewhere,..maybe even only the binaries.., but this is no security! Security is a customized feature of a system, and you need to chance to customize a firewall for your needs. ipfw is a way to secure systems like FreeBSD in a way, that will nearly guarantee full security. |

| | In today's ubiquitous networking environment, threats come in all shapes and sizes. And security analysts would like to believe that with a firewall in place, you are safe from network and systems exploitation. This just isn't so. In this article, I will look at one particularly popular attack: war dialing. |

| | People mean different things when they talk about cryptography. Children play with toy ciphers and secret languages. However, these have little to do with real security and strong encryption. Strong encryption is the kind of encryption that can be used to protect information of real value against organized criminals, multinational corporations, and major governments. |
