PREVENTING PHISHING ATTACKS BASED ON REPUTATION OF USER LOCATIONS |
摘要 |
User sessions are authenticated based on locations associated with a user account used for sending a request for creating a session. Examples of locations of a source of a request include a geographical location, a network address, or a machine cookie associated with a device sending the request. Locations of the request are compared with stored safe locations associated with the user account and a suspiciousness index is determined for the session. The level of authentication required for the session is determined based on the suspiciousness index. Locations are associated with a reputation based on past history of sessions originating from the locations. A location associated with a history of creating suspicious session is considered an unsafe location. Reputation of the location originating the session is used to determine the level of authentication required for the session. |

1. A computer implemented method comprising:
maintaining a safe locations database storing safe locations for user accounts, the safe locations database associating each user account with a set of safe locations; and updating the safe locations database by adding safe locations for a user account based on social networking connections of the user accounts, comprising:
receiving a request to create a session associated with the user account;identifying one or more locations associated with a source of the request;retrieving one or more stored safe locations of social networking connections of the user account from the safe locations database;matching locations from the identified one or more locations with the one or more stored safe locations retrieved from the safe locations database;determining that the request is authorized if at least one of the identified one or more locations associated with the source of the request matches a stored safe location retrieved from the safe locations database;responsive to determining that the request is authorized, selecting at least one of the identified one or more locations associated with the source of the request; andadding the selected location to the set of safe locations associated with the user account stored in the safe locations database. |
