Virus and worm attacks that spread through holes in popular consumer software emphasize the role the online public must play in preserving the safety and integrity of the Internet. To protect the network commons, more users must engage in safe online behavior by such actions as controlling their private information, updating software security patches, downloading protective software, and filtering their email.

In her talk, Professor Rifon will discuss a social-psychological approach to understanding Internet user privacy and security safety related behaviors.
