Cornell University proactively blocks Internet sites that pose a security threat to the university or the Cornell community. Websites are deemed a security threat when they host malicious software or scripts, or are used to try to steal Cornell login information or passwords.

The university performs this classification both internally, in response to attacks targeting us, and through automated input from industry standard cybersecurity threat feeds.

Cornell University does not block Internet sites unless our sources of threat information identify it as a risk to university computers, NetID credentials, or university data.
