Abstract
Techniques to limit the control of component hardware devices in a computer system by external devices or external software programs.
Claims20
A method comprising:
- responding to a first triggering signal by entering a trusted phase;
- complying with commands from any external source received during the trusted phase;
- responding to a second triggering event by entering an untrusted phase;
- and
- not complying with commands from any external source received during the untrusted phase.
2 more elements
An apparatus comprising:
- hardware component logic;
- and
- a filter device configured to:
- respond to a first triggering signal by entering a trusted phase,
- transfer commands to the hardware component logic from any external source received during the trusted phase,
- respond to a second triggering event by entering an untrusted phase, and
- not transfer commands to the hardware component logic from any external source received during the untrusted phase.
4 more elements
A system comprising:
- a host system comprising a processor, a memory device, storage device, and an intercommunication platform;
- a network interface communicatively coupled to the intercommunication platform, the network interface comprising:
- hardware component logic;
- and
- an I/O device configured to:
- respond to a first triggering signal by entering a trusted phase,
- transfer commands to the hardware component logic from any external source received during the trusted phase,
- respond to a second triggering event by entering an untrusted phase, and
- not transfer commands to the hardware component logic from any external source received during the untrusted phase.
6 more elements
A system comprising:
- at least one managed client device, wherein the managed client device comprises:
- hardware component logic;
- and
- an I/O device configured to:
- respond to a first triggering signal by entering a trusted phase,
- transfer commands to the hardware component logic from any external source received during the trusted phase,
- respond to a second triggering event by entering an untrusted phase, and
- not transfer commands to the hardware component logic from any external source received during the untrusted phase;
- and
- a management console configured to communicate with the at least one managed client device using a network.
