Abstract: The pureness of a connection between an external device and a host computer can be inspected or monitored to determine the status: connected or disconnected. When it is determined that a disconnection state is entered, an indication can be sent to the host and, in parallel, the data transportation from and/or to the external device may be manipulated. In some embodiments an exemplary connection protector device (CPD) may be added to the connection in between the external device and the host. The CPD can have two connectors one for the host and one for the cable of the external device. The CPD can be adapted to identify any disconnection in the connection with the host and/or the connection with the external device on the other side of the CPD.

Abstract: Secure operation of SEMDs on a client computer in a host system is obtained by controlling what applications (i.e., U3 applications) that can run on the host system and access data on the SEMD. Applications allowed to run on each host machine are identified and any access to the SEMD by an allowed application is permitted and other access are prohibited. Security and/or privacy for data that is stored on a SEMD is provided by only allowing approved USB memory card based applications to access the data stored on the SEMD. All other applications, either unapproved USB memory card based applications or non-SEMD resident cannot access the data on the SEMD. Other security is provided by preventing access to the SEMD except for computers or systems that are a part of a company's private network and maintaining the data on the SEMD in an encrypted state.

Abstract: Computers connected to a private network are monitored and controlled through the use of a client agent that operates in association with the computer and a server client that establishing security parameters, privileges and authorizations for the computer. The invention can prevent access to certain devices according to an active security policy. Any activity of the computer, such as a request to transfer data to an external device, access a particular file, etc. is monitored and controlled by the client agent. No operations or procedures are allowed by the computer inconsistent with the active security policy. The security policy may be set by the administrator of the private network according to the user rights and position in the organization.

Abstract: In a private network setting in which various computers can be attached, the confidential or sensitive data within the various devices on the private network is vulnerable. The ability to copy such confidential or sensitive data to a storage device communicatively coupled to a client computer on the network is governed and controlled. Only devices that include an authentic stamp or digital certificate can be accessed by client computers. If a device does not have a valid stamp or the stamp has been black listed, then the access to the device can be prevented or greatly limited.
