While the Internet is an amazing resource in terms of the information you can find and things you can do today, it’s important to also be smart about how you browse. A browser can be a great tool in helping you stay safe when you go online.
Most online attacks fall into one of the three situations:
Helping Protect You from Socially Engineered Attacks
A term that you may hear on occasion within the security realm is “socially engineered attacks.” What this means is an attacker uses clever techniques to get you to lower your guard and trick you into doing something that makes you vulnerable to an attack. The idea here is that they aren’t looking for weaknesses in code rather, they’re trying to fool you into a trap.
The ways in which we see this play out are varied it may be that you get spam – that is to say an email from a fake bank that actually takes you to a malicious site, or an email supposedly from a friend that encourages you to download a file which may contain malware. To help keep you safe from such types of attacks, Internet Explorer comes with the Smart Screen filter technology, which has been improved even more with Internet Explorer 9. SmartScreen makes it harder for someone to trick you into opening a malicious page, or con you with a phishing site. This technology checks to see if the site you’re visiting is suspected of hosting malicious code and subsequently prevents you from continuing on to that page. Internet Explorer 9 goes one step further by warning you only when you download applications that may be of higher risk.
Technologies like this can make a big difference in helping to keep you safe online. In December, NSS Labs reported that Internet Explorer offers the best protection against the spread of socially-engineered malware. As you can see in the below chart, Internet Explorer 8 (90%) and Internet Explorer 9 (99%) offer significantly more protection than other browsers.
Mitigating Attacks on Your Browser and PC
Internet Explorer also helps protect against deliberate attacks where bad code is hosted on a site that is designed to exploit weaknesses in the software on your PC. Among all the lines of code that make up software, there can be vulnerabilities. The Internet Explorer team designed its browser with security in mind, and in comparison to other browsers, Internet Explorer has fewer vulnerabilities. The chart below illustrates the number of publicly known vulnerabilities in 2010 divided by each browser, according to the National Vulnerability Database.
*Data source: National Vulnerability Database. Data is based upon the most recently shipped versions available during this time period. In the case of Chrome, versions 5, 6, 7, & 8 were all released during this time period.
At Microsoft, products are built with a secure-by-design approach, where security is designed into the product from the ground up. The result of this effort is a browser that includes specific features to help people stay secure and technologies that help insulate the browser against exploits. In addition to Microsoft’s security processes, which includes the Security Development Lifecycle, Software Security Incident Response Process (SSIRP), and monthly security bulletins, some ways in which you might see this at a product level include features such as Protected Mode, Data Execution Prevention, and many others, both in Internet Explorer 8, and the soon to be released Internet Explorer 9.
Protecting Against the Compromised Websites
This last scenario is when an attacker that has compromised a site that you visit in a way that interferes with how your browser relates to the site. This type of an attack is called a cross-site scripting attack. In this instance, an attacker gets an unsuspecting server to load special code on your browser that allows the attacker to do anything from monitoring your keystrokes to performing actions on your behalf on the site. Internet Explorer has built in a Cross-Site Script Filter that makes such attacks more difficult and helps protect you.
The upcoming release of Internet Explorer 9 contains even more features designed to help keep you safer such as ActiveX Filtering and Application Reputation. More information on how Microsoft technologies can keep you secure can be found here.

Most online attacks fall into one of the three situations:
1. Malware that relies on social engineering to spread
2. Attacks directed against your browser or your operating system
3. Attacks directed towards the websites you visit
Let me spend some time describing what I mean by each of these, and also how Internet Explorer can help protect you from each of these types of attacks.Helping Protect You from Socially Engineered Attacks
