Abstract
A credential caching system includes receiving a set of authentication credentials, storing the set of authentication credentials in a credential cache memory, wherein the credential cache memory is coupled with a management controller, and supplying the set of authentication credentials for automatic authentication during a reset or reboot. In the event of a security breach, the credential caching system clears the set of authentication credentials from the credential cache memory so that the set of authentication credentials may no longer be used for a reset or reboot.
Claims20
A credential security system, comprising:
- a management controller that is operable to be coupled to an information handling system (IHS) and to remain powered when the IHS is reset or rebooted, wherein the management controller is further operable to:
- receive at least one authentication credential;
- store the at least one authentication credential in a memory that is coupled to the management controller;
- and
- automatically supply the at least one authentication credential to the IHS for automatic authentication in response to a reset or reboot of the IHS;
- and
- wherein the at least one authentication credential is automatically cleared from the memory in response to a security breach.
An information handling system (IHS) security system, comprising:
- an IHS including an IHS processor coupled to an IHS memory;
- and
- a management controller coupled to the IHS and a network, wherein the management controller remains powered when the IHS is reset or rebooted, and wherein the management controller:
- receives at least one authentication credential over the network;
- stores the at least one authentication credential in a management controller memory that receives power from the management controller;
- and
- automatically supplies the at least one authentication credential to the IHS for automatic authentication during a reset or reboot of the IHS;
- wherein the at least one authentication credential is automatically cleared from the management controller memory in response to a security breach.
A method for securing credentials, comprising:
- receiving at least one authentication credential by a management controller that is coupled to an information handling system (IHS) and that remains powered when the IHS is reset or rebooted;
- storing the at least one authentication credential in a memory that is coupled to the management controller;
- and
- automatically supplying the at least one authentication credential to the IHS for automatic authentication in response to a reset or reboot of the IHS;
- wherein the at least one authentication credential is automatically cleared from the memory in response to a security breach.
