Abstract: Control systems and methods for providing a user with access to an external device via a communication network are provided, in which the external device is connected to a first port having lines including at least one power line and at least one data line, first and second of the lines being connected to a first switch and a second switch, respectively, of a first set of switches. A representative method includes: operating in an access-denied mode, in which one of the first set of switches is open to electrically disable the first port; receiving access request information requesting access to communicate with the external device; determining whether the user is authorized access; if the user is authorized access, providing the user an approval code; and in response to receiving login information and the approval code from the user, operating in the access-approved mode, in which the first port is enabled for a predetermined time period.

Abstract: Included are embodiments for notifying of electronic activity. One embodiment of a method, among others, includes receiving from a client an indication of a suspicious electronic activity, the client being associated with a user, gathering data related to the suspicious electronic activity, and calculating a frequency of appearance of at least one keyword within the data. Some embodiments include determining that the data is related to an undesirable incident based on whether the frequency of appearance meets a threshold and notifying at least one predetermined recipient of the undesirable incident.
