Internet Explorer 9 blocks 99% malware attacks: NSS Lab study!

Internet Explorer 9 blocks 99% malware attacks: NSS Lab study! 

IE9 continues to protect consumers

 With one third of internet users in Asia-Pacific alone becoming victims of threats like malware, the need for online security is more relevant than ever. To address these online concerns, Microsoft created their latest browser Internet Explorer 9, which provides a safe, secure yet beautiful and speedy browsing experience. Today, NSS Labs released two reports which show that SmartScreen feature in Internet Explorer continues to offer industry leading protection against socially engineered malware. As per the report “Internet Explorer 9 blocks an exceptional 99% malware. 96% of the live threats were caught with SmartScreen URL reputation in IE9, and an additional 3.2% with Application Reputation.”

What’s more, since the October 2010 NSS report, the average time taken by SmartScreen filter to block a threat has gotten 28% faster, if Application Reputation is considered, then the average time has improved by 85%. The graph below compares the test results from various browsers and shows that Internet Explorer blocks 5X more malware than competitive browsers.

 

 

 

 

 

 

 

 

 

 

The other reports looked at socially engineered malware targeted towards people living in Asia Pacific region and in Europe. As you can see below, in each region the results remained consistent – Internet Explorer 9 maintains a lead in protecting users from live threats.

 

 

 

 

 

 

 

 

 

 

* You check out the entire web browser security report by NSS Labs by clicking here: https://www.nsslabs.com/assets/noreg-reports/2011/nss%20labs_q3_2011_browsersem%20GLOBAL-FINAL.pdf.

It is no surprise that a browser is the first line of defense against attacks from the web and it plays an important role to help keep you safe online. Internet Explorer is designed with your security and privacy in mind. The new browser has a robust set of built-in security, privacy, and reliability technologies that helps keep consumers safe and their browsing experience virtually uninterrupted. With IE9, we have introduced new functionalities like Tracking Protection, Tracking Protection Lists, ActiveX Filtering to name a few. IE9 makes browsing the web even safer & protected experience from here on.

IE9 has received positive feedback from consumers globally. As of today, Internet Explorer 9 has over 18% usage share worldwide on Windows 7. You can download Internet Explorer 9 to see how you can enjoy a more beautiful – and trusted web!

How do I restore security settings back to default.

February 11th, 2011 by and tagged ,

Few times, it is mandatory to reset the security permission on the all the files & folder after messing around with ACL or with GPO to set an ACL, restraining users from making any changes. Even though machine is disjoint from the domain, but same settings of ACL still remain & we get access denied while doing the changes or creating installation.

I would recommend taking backup of the system, prior to doing reset of security settings,so in case things don’t go as expected, making it more troublesome than easy, system state backup is always handy.

Take a look at below KB, which applies almost all the version of windows except all versions of 2000 & below.

Normal Domain Users Can Join default 10 machines to a domain

February 6th, 2011 by and tagged

By default, any domain users can add up to 10 machines to a domain, the reason is Every domain has a default setting for ms-DS-MachineAccountQuota value 10. You can modify this object in directory to prevent the domain user from joining the machine into domain by using ADSIedit tool to prevent this behavior.

WARNING Using Adsiedit incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Adsiedit can be solved. Use Adsiedit at your own risk.

  1. Install the Windows 2000/2003(2008/R2, adsiedit is pre-installed) Support tools if they have not already been installed. Run Setup.exe from the SupportTools folder on the Windows 2000/2003 Server or Professional CD-ROM.
  2. Run Adsiedit.msc as an administrator of the domain. Expand the Domain NC node. This node contains an object that begins with “DC=” and reflects the correct domain name. Right-click this object and then click Properties.
  3. In the Select which properties to view box, click Both. In the Select a property to view box, click ms-DS-MachineAccountQuota.
  4. In the Edit Attribute box, type the number of workstations that you want users to be able to maintain concurrently.
  5. Click Set, and then click OK.

Once above steps are done, if user tried to add machine new machine into domain, he will encounter below error message.
