nucoder_190_3

Lots, even MOST PHP applications are Open Souce but what if you want to distribute your application but don't want to distribute your PHP Source Code ?

Check out Nu-Coder from NuSphere.

 

Nu-Coder converts the source code of PHP Script into compiled PHP bytecodes for both accelerated runtime performance and maximum security.

Dolores Labs posted recently "Amazon’s S3 Web Service, our #1 cause of failure" [ Click HERE to READ ]

100014192753__V46777512_

Amazon.com is a great company and a early innovator in the Web Services Community. (God knows I send them ALOT of money.)

So this is not an indictment of Amazon as a technology provider. In fact, it is because a Amazon is a great company with a solid infrastructure that this is significant.

As Geeks, we tend to get all jazzed about the latest buzz - and cloud computing is certainly one of them. But, I think it's important to remember, while services in the cloud can be very cost effective. You can't control the cloud.

When you build it and own it you always have options when you're not getting the service level you need. In the cloud, you're held hostage by 3rd party service levels.... ad as we all know, stuff happens.

When you're using a cloud hosted service, remember to build support for graceful degradation your application. You application need not fail completely because you can't fetch images, ads, etc.

Not only is this good design practice, but it mitigates a DOS security threat. If I wanna bring your web application down and you haven't built resilience into your site, all I need to to is successfully attack any one service your application depends on and your application is down !!

TweakUAC

Dies UAC give you a rash ?

It does me !!!

It's not that it isn't a good idea - it is. But I really wish I could train it or over ride it.

Maybe in a future Windows version - in the mean time, I'm trying Tweak UAC which provides a "Quiet Mode" for UAC.

[ Click HERE to get Tweak UAC ]

Note: UAC is a Security feature. Strictly speaking "Quiet Mode"  reduces your system's security.

Check out this 2 day security brain fest. It happens to be right after Black Hat in Vegas. See you there ?

The LifeCycleSecurity conference was started to provide a venue where professionals in the Application Security industry can learn from each other's experiences.  We will be addressing security from the server to the browser. 

Application Security : We will have topics that address how professionals are creating systems that are resistant to attacks against the web application layer and the systems that support these web applications.

Browser security: With the increase in attacks against browsers such as malware and other attack vectors, protecting your users is more important than ever.  This is increasingly being done with content filtering devices.  The Lifecyclesecurity conference will include several tracks that address techniques that are being used to protect against these browser / content based attacks.

While at TechEd 2008 I got to spend some time in the "Fish Bowl" with Georgeo Pulikkathara.

Georgeo interviewed me on Microsoft's Secure Development Lifecycle (SDL) and my upcoming Developer Security Activities.

Microsoft has released an advisory for the recent SQL Injection attacks which points to several tools that will help identify and block these type of attacks. The goal of this blog post is to help our audience identify the best tool depending on their role (i.e. Web Developers vs IT administrators). Currently, there are three tools available which serve different purposes and they complement each other.

 Web developers Recommendations

·         The Microsoft ® Source Code Analyzer for SQL Injection is a static code analysis tool that identifies SQL Injection vulnerabilities in ASP code (ASP pages are the ones that have been under attacked). In order to run this tool you will need source code access and the tool will output areas vulnerable to SQL injection (i.e. the root cause and vulnerable path is identified). In our view fixing the root cause of the bug is the best way to eradicate vulnerabilities. The tool scans ASP source code and generates warnings for first order and second order SQL Injection vulnerabilities.

 

IT/Database administrators Recommendations (Web developers can benefit from this as well)

We are recommending two tools, one can help identify SQL injection vulnerabilities by crawling the website (for example, when access to the source code is not possible) and the other one aims to block potential SQL injection attacks.

·         HP Scrawlr, developed by the HP Web Security Research Group, will crawl a website, simultaneously analyzing the parameters of each individual web page for SQL Injection vulnerabilities (Microsoft has worked with HP in this effort). Scrawlr uses some of the same technology found in WebInspect but has been built to focus only on SQL Injection vulnerabilities. This will allow an IT/DB admin to easily find vulnerabilities similar to the ones that have been used to compromise sites in the recent attacks. No source code is required to run this tool. From a starting URL, the tool recursively crawls that URL in order to build up a site tree that will be then analyzed for SQL injection vulnerabilities. For more information check out https://download.spidynamics.com/products/scrawlr/ 

 

·         Second, in order to block and mitigate SQL injection attacks (while the root cause is being fixed), one can deploy filters using URLScan 3.0. This tool restricts the types of HTTP requests that Internet Information Services (IIS) will process. By blocking specific HTTP requests, UrlScan helps prevent potentially harmful requests from being executed on the server. Basically, it uses a set of keywords to block certain requests (i.e. the request will get drop and never processed by SQL) That said, we highly encourage fixing the root cause of the problem instead of attempting on producing a perfect filter that will block all type of attacks (since in our view this is not possible and error prone).

 

The following table summarizes the pros and cons of these tools.

 

Tool

Usage

Pros

Cons

Users

Microsoft Source Code Analyzer for SQL Injection

Identifies SQL Injection vulnerabilities in ASP code through static code analysis.

Identify the root cause of the bug at the source code level.

This version currently only works on ASP pages

Web developers

Scrawlr

Detect SQL vulnerability by crawling a website.

No source code is required.

Cannot identify the line of code responsible.

 

IT/DB Administrator

Web developers

UrlScan v3.0 Beta

Blocks the types of HTTP requests that Internet Information Services (IIS) will process.

URLScan filter can be easily deployed to mitigate SQL injection attack while the root cause is being fixed.

Not fixing the root cause, thus the risk has not been eliminated completely.

June 20, 2008 (IDG News Service) Microsoft's June security updates were bad news for online criminals who make their living stealing password information from online gamers.

The company's Malicious Software Removal Tool -- a program that detects and removes viruses and other undesirable programs from Windows machines -- zapped game password-stealing software from more than 2 million PCs in the first week after it was updated to detect these programs on June 10.

 

One password stealer, called Taterf, was detected on 700,000 computers in the first day after the update. That's twice as many infections as were spotted during the entire month after Microsoft began detecting the notorious Storm Worm malware last September.

HHacker

Baseline Magazine [ Click HERE ] has outlined the 5 Big Security Threats that Anti-virus software and firewalls MISS.

1 Trusted Users and Partners

2 Web Application Vulnerabilities

Gartner estimates that 75 percent of today’s attacks are carried out through the application layer.

Many of these application attacks are conducted through quickly coded Web applications, with little or no security baked in.

Yet these Web apps are often connected to some of the most sensitive databases businesses own.

3 Missing Devices

4 Custom Malware

5 Social Engineering
