8. 8 Secure and Trustworthy Browsing Security is job #1 Dynamic protection against web fraud Full user control over add-ons Advanced malware protection U D A C I

9. 9 Anti-phishing service integrated into IE User experience highlights security Clear secure connection user experience Pop up windows identified with their URL “One Click Cleanup” feature to wipe history, cache, etc. Integration of Parental Control (Vista ) U D AI Secure and Trustworthy Browsing Dynamic protection against web fraud

11. 11 Explicit user consent is required on first run of installed ActiveX controls Users can easily enable pre- installed controls through the same Info Bar as new controls Add-ons Disabled Mode for recovery U D A C I Secure and Trustworthy Browsing Full control over add-ons

12. 12 Special characters complicate URL parsing, e.g. http://www.good.com@bad.com URLs are often passed as strings, and some components parse inconsistently In IE7, we have a single URL parsing object This API (IURI) is exposed for other apps to use Also adds International Domain Name (IDN) Secure defaults to prevent spoofing U C I Secure and Trustworthy Browsing Impeding critical exploits – URL handling

13. 13 javascript: protocol now runs in-page Now, doesn’t navigate – we strip “javascript:” off and run as script inside the page context Objects handling data by reference must understand HTTP redirects We’ve always had redirect notifications – but now we lock the data if the object doesn’t understands redirects. Objects that aren’t redirect-aware can’t get access to the data. I Secure and Trustworthy Browsing Impeding critical exploits – cross-domain

14. 14 Malicious web pages often install malware or modify files by exploiting buffer overruns or other critical security exploits in IE or add- ons Solution: Protected Mode Reduces the severity of threats to IE and add-ons running in IE by eliminating the silent install of malicious code on the user’s system Protects registry, file system from silent malware installs Does NOT prevent running Win32 code U C I Secure and Trustworthy Browsing Advanced malware protection

15. 15 Protected Mode restricts IE from writing files outside of the Temporary Internet Files folder IE’s process has fewer write privileges than normal User Protected Mode builds on the Windows Vista Mandatory Integrity Control (MIC), which restricts writes This means Protected Mode is Windows Vista only! When IE needs to write outside of the TIF folder (e.g. File…Save As), we have a broker process with appropriate privileges to do so Compatibility layer for add-ons to elevate privs U C I Secure and Trustworthy Browsing Protected Mode summary
