為什麼一個唯一AV引擎不是足够!

這是正義的證明我的點-一個唯一AV引擎不是足够,如果您想要是安全的。

我今天有這個問題在顧客-用戶在她的信使接受了一個鏈接… 并且她點擊它和大概被接受執行事=> Pooof (所有她的MSN信使聯絡發送了同樣的消息到多個新聞組以蠕蟲的鏈接)!

我們設法在更新署名以後使用一些不同的網上掃描器-,因為地方AV引擎(沒有被提及的名字)沒有發現什麼-。 我嘗試的網上掃描器首先沒有顯示什麼。 如此,這臺特殊網上掃描器結果是非常涼快和有效的:

我可以推薦這個掃描鏈接,每當您有您想要掃描的一個可疑文件: http://virusscan.jotti.org/

您能看它使用幾個引擎確定文件是否被傳染或沒有-很好, thanx!

限制突岩通入與ISA 2004/2006

如果您調查了「洋蔥圈」或者」突岩「您大概想知道阻攔通入從這些是否是明智的 匿名 服務器(或可能出口結)。 我不談論怎麼被加密的突岩網絡運作,因為很多信息可以被發現「那裡」。 主要來源應該是: www.torproject.org 或許-和 WikiPedia.

作為安全人(或 ISA administrator maybe), you ask yourself "why do these people want to be anonymous"? In this case "anonymous" means that "they" don’t want targets on the Internet to see the originating IP address (the source). A "target" is typically a web site or some other web service.

The answer? Well, first you gotta ask yourself: "who are they"? And there’s really no good answer to that question I guess - who really knows? All we can do is guess, so let me turn these questions around: if I were to try out a hack, or some new exploit, would I do it directly over my personal WAN IP? Or would I try to "hide" my originating IP? If you look at it in that

SQL attacks - the lethal injection

Hi there,

Let everybody know the two very simple golden rules when it comes to web-applications that are communicating with SQL servers:

1. Never send user input text strings directly to the (backend) SQL server(s). Make sure to "clean it up" first (eg. no special chars etc.). Only accept thing you KNOW you want.

2. Always use Stored Procedures and call them with arguments instead of letting text strings (SQL injections) take control of your (backend) SQL server(s).

Sticking to those rules will make life a lot easier for admins, consultant and security guys like me. Tell you company developers, thirds party software vendors etc. to stick to the rules (even though they should know them by heart already) - spread the word and life will be a lot easier for all of us good people around the globe :)
