Abstract
Methods and apparatus to manage transmissions between domains and memory are disclosed. An example electronic communications security system disclosed herein includes media storage; a first host bus adapter (HBA) serial attached small computer system interface (SCSI) (SAS) card to: communicatively couple a first domain to the media storage; and enable transmission of first data from the first domain to the media storage; and a second HBA SAS card that is write-block enabled to: communicatively couple a second domain to the media storage; enable access of the first data from the media storage by the second domain; and prevent second data from exiting the second domain.
Claims18
An electronic communications security system comprising:
- media storage;
- a first host bus adapter (HBA) serial attached small computer system interface (SCSI) (SAS) card to:
- communicatively couple a first domain to the media storage;
- and
- enable transmission of first data from the first domain to the media storage;
- and
- a second HBA SAS card that is write-block enabled to:
- communicatively couple a second domain to the media storage;
- enable access of the first data from the media storage by the second domain;
- and
- prevent second data from exiting the second domain.
The system of claim 6, wherein the second HBA SAS card is to prevent transmission of data from any of the second plurality of computing devices to the first plurality of computing devices.
An electronic communications security system comprising:
- means for storing media;
- first means for connecting to the means for storing, the first means for connecting to:
- communicatively couple a first domain to the means for storing;
- and
- enable transmission of first data from the first domain to the means for storing;
- and
- second means for connecting to the means for storing, the second means for connecting being write-block enabled, and the second means for connecting to:
- communicatively couple a second domain to the means for storing;
- enable access of the first data from the means for storing by the second domain;
- and
- prevent second data from exiting the second domain.
A method of gatekeeping data transmission between electronic devices, the method comprising:
- enabling transmission of first data from a first domain to a media storage, the first domain having a first classification, the first domain communicatively coupled to the memory via a first host bus adapter (HBA) serial attached small computer system interface (SCSI) (SAS) card;
- enabling access of the first data from the memory by a second domain, the second domain having a second classification different than the first classification, the second domain communicatively coupled to the memory via a second HBA SAS card, the second HBA SAS card being write-block enabled;
- and
- preventing second data from exiting the second domain.
