No, not an issue with the PHP - I was responding to "AJAX not being cross site is annoying"
MaxMouse
Really? i thought that would only be important if the user had some kind of control over where the XML came from, if you hard code it (As in a PHP file) wouldn't that eliminate XSS attacks?
Domuk
Yes, but very, very necessary. AJAX requests run in the context of the browser, there'd be no security if it was cross-domain .
MaxMouse
AJAX not being cross site is annoying, all other scripts can be used in that way, having to resort to PHP to patch it is a shame.

Security: A Hash-Based Secure Block Encryption Algorithm
by: anilg - 2006-06-16 12:28:02
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).

Security: Reversing Malware I: The Science of Malware Analysis

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.

Security: SQL Injection
by: TroPe - 2004-12-13 16:34:38
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!

Security: Understanding Viruses
by: nirus - 2004-07-04 14:33:29
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.

Security: customized and most secure firewall

Security: Cryptography
by: dimport - 2003-06-21 07:19:46
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.
