Rating communicating entities based on the sharing of insecure content

At least one non-transitory computer readable storage medium for protecting a first user from insecure content disseminated by other users that are members of one or more user groups of which the first user is a member, the at least one non-transitory computer readable storage medium storing computer executable instructions that, when loaded into computer memory and executed by at least one processor of a computing device, cause the computing device to perform the following steps:

• tracking communications received by a computing device and originating from specific ones of the other users that are members of one or more user groups of which the first user is a member, each user group comprising an association of users in a social media or other electronic communication distribution context;
• maintaining a corresponding unique user identifier for each specific one of the other users that are in one or more user groups of which the first user is a member;
• for each specific one of the other users that are in one or more user groups of which the first user is a member, configuring an associated security rating comprising a quantification of a security risk of receiving communication from the associated specific user;
• performing a security analysis of content received by the computing device from specific ones of the other users that are members of one or more user groups of which the first user is a member;
• adjusting security ratings associated with given users that are members of one or more user groups of which the first user is a member, responsive to given security analyses of content received by the computing device from given associated users identifying given security concerns;
• and
• responsive to a specific security rating associated with a specific user that is a member of one or more user groups of which the first user is a member exceeding a predefined threshold, taking a security action that prevents the first user from being exposed to communication from the specific user.

A computer system comprising:

• system memory;
• a group member tracking module residing in the system memory, the group member tracking module being programmed to track communications received by a computing device and originating from specific ones of the other users that are members of one or more user groups of which the first user is a member, each user group comprising an association of users in a social media or other electronic communication distribution context
• an identification maintaining module residing in the system memory, the identification maintaining module being programmed to maintain a corresponding unique user identifier for each specific one of the other users that are in one or more user groups of which the first user is a member;
• a security rating configuring module residing in the system memory, the security rating configuring module being programmed to configure, for each specific one of the other users that are in one or more user groups of which the first user is a member, an associated security rating comprising a quantification of a security risk of receiving communication from the associated specific user
• a content analysis performing module residing in the system memory, the content analysis performing module being programmed to perform a security analysis of content received by the computing device from specific ones of the other users that are members of one or more user groups of which the first user is a member;
• a security rating adjusting module residing in the system memory, the security rating adjusting module being programmed to adjust security ratings associated with given users that are members of one or more user groups of which the first user is a member, responsive to given security analyses of content received by the computing device from given associated users identifying given security concerns;
• a security action taking module residing in the system memory, the security action taking module being programmed to take, responsive to a specific security rating associated with a specific user that which is a member of one or more user groups of which the first user is a member exceeding a predefined threshold, a security action that prevents the first user from being exposed to communication from the specific user;
• and
• at least one processor configured to execute the modules.
