The three default security levels are medium, medium-high and high. We can also use the “Custom level” button to change the default security level of each zone and their details. This includes ActiveX control behavior, scripting or user authentication settings.

Different zones will apply different security settings to websites that are in that zones. Local intranet zone contains sites that are found on our intranet, in our organization. IE can detect intranet sites automatically. We can also manually add websites to this zone. The default security level of the Local intranet sites zone is medium-low. To check default settings we can click on the Sites button.

Restricted sites are potentially malicious and that can damage our computer. The default security level for restricted sites is high.

The Internet zone contains all websites that are not contained in the other three security zones. The default security level for the Internet zone is medium-high. Internet Explorer also has a new feature called Protected Mode. Protected mode will not allow infected IE to damage other parts of the Windows system. By default Protected Mode is enabled for sites in the Internet and Restricted sites zone.
