Best Tips to Protect your Web Sites from Hackers and Malicious contents

The Web is scarier than most people realize, according to research published recently by Google.These Web-based attacks become much more common in recent years as firewalls and better security practices by Microsoft have made it harder for worms and viruses to directly attack computers. Nowadays about 1.3 percent of all Google search queries list malicious results somewhere on the first few pages.

Criminals are getting better at this kind of work. They have built very successful automated tools that poke and prod Web sites, looking for programming errors and then exploit these flaws to install the drive-by download software. Often this code opens an invisible iFrame page on the victim’s browser that redirects it to a malicious Web server. That server then tries to install code on the victim’s PC. “The bad guys are getting exceptionally good at automating those attacks,”

[ad#add-top-in]

Following are some tips to get rid of this hackers or hijackers activity.

– Keep you password and username safe change it frequently only with strong password check your password with Microsoft

– Keep your PC clean from viruses and spy-wares because there are chances to hijack your PC contents and login cookies etc. Scan your PC for viruses now with NOD32 Online Antivirus Scanner

– Keep all folders and files permissions proper in your web hosting accounts/server. Never give full permission for the folders and files, that means read write and execute permission. If you are hosting sites in Linux platform never give 777 permission (read write and execute permission) to all members even for net users of file and folders. The preferred maximum permission is 755. This means write permission for root user and only read and execute permission for others.

– There are many techniques used to hack/hijack the website

Cross Site Scripting (XSS)

SQL injection flaws

Site reconnaissance

Session hijacking

Application denial of service

Cookie/session tampering

To withstand from this you need “professionally well designed websites” and also powerful web sitefirewall at server end.

– You need to choose good web hosting platform or company which provides good firewalls and Security. If you are going for Linux platform better to choose Grsecurity enabled kernel Servers; especially for shared hosting.

– But not the least the best way to find the flow in website is by checking the web site stats all the day. By this you can find the links/URL which are not related to your website so that you can delete it before it spreads through search engines.

– If some one reports your site having virus then its 99% sure your site home pages are having masked IFrames at the beginning or last lines of the page, which actually downloads virus file form some other server/site. You can fix it your self by editing your home page and removing the contents which looks like as shown bellow.

These are some of the tips which really helps to protect yourself from Hackers and Malicious contents

Google had security issue with its GrandCentral.com telecom service and Google.com : Fixed

Google

Google has fixed security issue related to its Central telecom service and its Google.com Web site..

Google fixed a cross site scripting exposure on the log-in page for Grand Central, a service that allows people to have numerous phone numbers ring on one phone and have a unified voice mail.

A cross-site script is a vulnerability found increasingly in Web applications in which malicious code can be injected into Web pages that could be used to attack or compromise visitors to the site.

“This issue was reported on Monday morning, and google closed it shortly after being notified”.

The vulnerability was posted to a security e-mail list called Full Disclosure and was not reported to Google in advance, meaning Google had to race to fix the issue before someone could write an exploit for it.

[ad#add-top-in]

In a separate security issue, Google fixed a weakness that allowed people to create a spoof site that looks like it goes to the Google.com domain but actually redirects a Web surfer to a different site. Such redirect links are usually distributed via e-mail and often send people to a site with malicious code that can be used to attack or compromise the visitor’s computer.

Google, meanwhile, was working to fix a redirect vulnerability related to the site of its DoubleClick online advertising unit.

Yahoo

Yahoo announced software called BrowserPlus that has a similar philosophy. Expand what’s possible to make Web applications a better alternative to programs running natively on a personal computer. Right now, it’s available only in a “sneak peek” on some Yahoo-operated Web sites.

But a year after the Google launched its Gears project, Google appears to be trying to make it easier for competitors to embrace Gears. At its Google I/O conference here Wednesday, Google de-branded Gears today, taking its name off the project and announcing some new Web browser support in the works.

“BrowserPlus is a technology designed to extend the Web, so that developers can build more exciting Web applications and so end users can get more done inside their Web browsers,” Yahoo said on a BrowserPlus frequently-asked-questions page.

Different Web sites can use BrowserPlus to support things like drag and drop from the desktop, easier file uploads, more efficient and secure acquisition of feeds and information, and native desktop notifications.

BrowserPlus works on Mac OS X 10.4 and 10.5 machines and on Windows XP and Vista machines. Supported browsers are Internet Explorer 7 or later, Apple Safari 3 or later, and Firefox 2 or later.

Microsoft Live Mesh Launch on April 24

Live Mesh

Earlier this year at Mix 08, Microsoft Chief Software Architect Ray Ozzie vaguely referred to the Mesh concept as a way to use the Web through Microsoft products to connect devices, entertainment, businesses and development.

Now Microsoft plans to launch its Live Mesh offering next week at the Web 2.0 Expo in San Francisco but so far is not revealing details of the service.

On Friday night, Microsoft sent out e-mail invitations to a “Mesh it up” event on April 24 featuring demos by Microsoft “experts.” The invitation includes a reference to the mesh.com Web site, which currently requires visitors to sign in with a Windows Live ID and then displays an error message.
[ad#add-top-in]
Microsoft declined to offer any more details about Live Mesh except to say that it will launch next week and further information will become available on Tuesday evening, April 22.
