Overview of Zone Security Options
Overview of Low Level Security
IntelliDefense uses threat-assessment technology to control incoming and outgoing communication for programs. (More on IntelliDefense.)
IntelliDefense is enabled by default; you can turn the feature on and off from the General tab of the Settings window, by selecting or clearing the Enable IntelliDefense check box.
Note: IntelliDefense applies to the programs that do not have a program policy.
IntelliDefense first checks to see if a program attempting communication is signed by a software publisher you have designated as trusted. You control which publishers are trusted; click Manage Trusted Publishers to open the Manage Trusted Publishers window.
If the program is not signed by a trusted publisher, then IntelliDefense determines which classification the program belongs to. Based on that classification, iolo Personal Firewall takes the associated action that is shown on this tab:
Allow. Allow the communication attempt.
Block. Block the communication attempt.
Prompt. Generate a prompt. (More on how the firewall handles generated prompts.)
To follow is a list of each IntelliDefense classification, with its fixed setting in the Low level and a description of its purpose.
