Abstract

According to one embodiment, a computer system executing a computer program is coupled to multiple secure network domains configured in a multi-level security architecture. The computer program simultaneously establishes a voice connection with a first terminal configured on a first secure network domain and a second terminal configured on a second secure network domain. The computer program may then selectively couple an electroacoustical transducer to the first terminal or the second terminal, and generate an indicator on a user interface indicating the security level of the selected terminal.

Claims

1. A computer program product comprising:

an executable applet embodied on a computer system that is coupled to a user interface, the applet restricted to execution within a web browser, the computer system coupled to a first secure network domain having a first of a plurality of security levels and a second secure network domain having a second of the plurality of security levels, the first secure network domain and the second secure network domain are configured in a multi-level security architecture in which the second security level being different from the first security level, the executable code in communication with an electroacoustical transducer comprising a microphone and a sound generating device, the applet, when executed by the computer system being operable to;

simultaneously establish a voice connection with a first terminal configured on the first secure network domain and a second terminal configured on the second secure network domain;

simultaneously couple the microphone to the first terminal and the sound generating device to the second terminal;

generate, on the user interface, a first visual indicator portion indicating the security level of the first terminal, and a second visual indicator portion indicating the security level of the second terminal.

2. A computer program product comprising:

executable code embodied on a computer system that is coupled to a user interface, the computer system coupled to a first secure network domain having a first of a plurality of security levels and a second secure network domain having a second of the plurality of security levels, the executable code in communication with an electroacoustical transducer comprising a microphone and a sound generating device, the code, when executed by the computer system being operable to;

simultaneously establish a voice connection with a first terminal configured on the first secure network domain and a second terminal configured on the second secure network domain;

selectively couple the electroacoustical transducer to the first terminal or the second terminal; and

generate an indicator on the user interface indicating the security level of the selected terminal.

3. The computer program product of claim 2, wherein the code is further operable to:

simultaneously couple the microphone to the first terminal and the sound generating device to the second terminal;

wherein the indicator comprises a first indicator portion indicating the security level of the first terminal, and a second indicator portion indicating the security level of the second terminal.

4. The computer program product of claim 2, wherein the indicator comprises a visual indicator that is displayed on the user interface.

5. The computer program product of claim 2, wherein the code comprises an applet that is executed on the computer system.

6. The computer program product of claim 5, wherein the applet is restricted to execution within a browser that is executed on the computer system.

7. The computer program product of claim 2, wherein the electroacoustical transducer comprises a microphone and the user interface comprises a push-to-talk button, the code further operable to selectively couple the microphone to the first terminal or the second terminal according to actuation of the push-to-talk button.

8. The computer program product of claim 2, wherein the first secure network domain and the second secure network domain are configured in a multi-level security architecture.

9. The computer program product of claim 2, wherein the voice connection comprises an intercom connection, the code operable to:

establish the voice connection with a third terminal having a third security level of the plurality of security levels; and

dynamically modify the indicator to indicate the third security level associated with the third terminal.

10. the computer program product of claim 9, wherein the code is operable to indicate, using the indicator, the security level of the lowest security level of the first terminal, the second terminal, and the third terminal.

11. The computer program product of claim 2, wherein the code is further operable to implement a positive inclusion mandatory access control (MAC) policy by authenticating only pre-registered users of the executable code.

12. The computer program product of claim 2, wherein the first terminal or the second terminal is coupled to the computer system through a wireless network.

13. The computer program product of claim 2, wherein the indicator comprises one of a plurality of colors.

14. The computer program product of claim 2, wherein the first security level of the first secure network domain is different from the second security level of the second secure network domain.

15. A computer implemented method comprising:

simultaneously establishing a voice connection with a first terminal configured on a first secure network domain and a second terminal configured on a second secure network domain, the first secure network domain having a first of a plurality of security levels and the second secure network domain having a second of the plurality of security levels;

selectively coupling an electroacoustical transducer to the first terminal or the second terminal, the electroacoustical transducer comprising a microphone and a sound generating device; and

generating an indicator on a user interface indicating the security level of the selected terminal.
