Test_1-4
TEST 1
Test Case ID: BIS-1.1.1 Test Name: TC_ID_SECURE_DEBUG_INTERFACES
Objective
To identify the availability of debugging interfaces (e.g., USB, UART, JTAG, or other serial variants) in the DUT by reviewing the datasheet of the SoC used in the device under test.
Tools Used
OEM-provided SoC datasheet
DUT hardware documentation
Technical specifications document
Test Execution Steps
Document Collection
Obtain the official datasheet from the OEM detailing all ports/interfaces available on the SoC used in the DUT.
Document Review
Review the datasheet and related documentation to check for the presence of any debugging interfaces such as USB, UART, JTAG, or other serial communication ports.
State Verification
Verify in the documentation whether each identified interface is enabled, disabled, or protected by an authentication mechanism in the production firmware/hardware.
Expected Results for Pass
All available debugging interfaces are clearly identified as per OEM documentation.
The default operational state (enabled/disabled/protected) is specified for each interface in the production configuration.
Test Observations
(Insert your findings here — e.g., "OEM documentation indicates UART and USB debug interfaces are physically present but disabled in production units.")
Evidence Provided
Copy of SoC datasheet highlighting interface details
Screenshot or excerpt from OEM interface configuration document
Photographic evidence of DUT ports (if applicable)
Test Case Result
☐ Pass – Interfaces identified and state documented as per requirement ☐ Fail – Missing/incorrect identification or unclear interface state
TEST 2
Test Case ID: BIS-1.1.2 Test Name: TC_VERIFY_SECURE_DEBUG_INTERFACES
Objective
To verify and validate that all debug ports/interfaces enabled in production devices match the vendor documentation, and that the declared access control mechanisms (e.g., password complexity, authentication controls) are correctly implemented and effective.
Tools Used
OEM-provided debug/communication tools
DUT production firmware configuration
Serial/USB/UART interface testing hardware (if applicable)
Test Execution Steps
Production Configuration Setup
Ensure the DUT is configured to match production environment settings.
OEM Documentation Review
Obtain OEM documentation specifying all debug interfaces, their default operational state, and implemented protection mechanisms.
Interface Interaction
Attempt to connect to each debug interface using OEM-provided debugging and communication tools to determine operational status.
Security Validation
If an interface is declared as protected, attempt controlled access to confirm the effectiveness of the security measures (e.g., password authentication, access control).
If an interface is declared as disabled, verify no interaction or access is possible.
Expected Results for Pass
All debug interfaces match the state documented by the OEM (enabled/disabled/protected).
Declared access controls (password complexity, access control mechanisms) function effectively and prevent unauthorized access.
Test Observations
(Insert findings here — e.g., "UART interface detected physically but disabled in firmware; USB debug port enabled with password authentication; password complexity validated successfully.")
Evidence Provided
Screenshots of access attempts
Serial console logs
Photographs of DUT interface panels with status indication
OEM documentation excerpts
Test Case Result
☐ Pass – All interfaces and protections match OEM documentation ☐ Fail – Discrepancy between documentation and actual interface state or protection
TEST 3
Test Case ID: BIS-1.1.3 Test Name: TC_OEM_SECURE_DEBUG_INTERFACES
Objective
To test, in the presence of the OEM team, the enabling/disabling status of all ports and debugging interfaces (e.g., USB, UART, JTAG, and other serial variants) using relevant hardware-based debuggers and to verify that appropriate access control mechanisms are in place if any interface is enabled.
Tools Used
OEM-provided debug/communication tools
Hardware-based debuggers (USB/UART/JTAG adapters)
DUT configuration interface (CLI/Web UI if applicable)
Multimeter or logic analyzer (for signal detection, if required)
Execution Steps
Session Coordination
Schedule and conduct the test session with the OEM team present to ensure transparency and validation.
Interface Status Verification
Systematically check each physical and logical debug interface to confirm its operational state matches OEM documentation.
Security Mechanism Testing
Where an interface is enabled, use hardware-based debuggers and access control tools to validate authentication and protection mechanisms.
Disablement Validation
Where an interface is documented as disabled, confirm no data or interaction is possible through physical or logical connection attempts.
Expected Results for Pass
Enable/disable status for each interface matches OEM documentation.
All enabled interfaces have effective protection mechanisms in place.
Disabled interfaces show no response to access attempts.
Test Observations
(Insert findings here — e.g., "USB debug interface detected and disabled as per documentation; UART interface enabled with password authentication, verified functional; JTAG disabled and no signal detected.")
Evidence Provided
Photographs of DUT with ports highlighted
Logs from debugger connection attempts
Screenshots of access control validation
OEM-signed confirmation document
Test Case Result
☐ Pass – All interface states validated successfully in OEM presence ☐ Fail – One or more discrepancies found between documentation and observed results
TEST 4
Test Case ID: BIS-1.1.4 Test Name: TC_PROCESS_SECURE_DEBUG_INTERFACES
Description
To conduct a process audit of the manufacturing facility to validate the vendor’s claim that all debugging interfaces (USB, UART, JTAG, and other serial variants) are closed/disabled or adequately secured during the device provisioning stage.
Tools Used
Vendor-provided manufacturing/provisioning documentation
Audit checklist (derived from vendor security claims and requirements)
Block connection diagrams and process flowcharts
OEM process compliance documents
Execution Steps
Audit Preparation
Develop an audit checklist based on vendor security requirements and claims regarding debug interface management.
Process Review
Review the actual provisioning process steps against the documented claims for disabling or securing debug interfaces.
Documentation Assessment
Examine vendor-provided block connection diagrams, process flowcharts, and relevant provisioning records to ensure alignment with stated security measures.
Verification
Confirm that any debug interfaces present are appropriately secured or disabled before the device leaves the manufacturing facility.
Expected Results for Pass
The manufacturing/provisioning process fully matches the vendor’s documented claims.
Debug interfaces are confirmed to be disabled or secured during provisioning.
Documentation (block connection diagrams, process flows) is consistent with actual practice.
Test Observations
(Insert findings here — e.g., "Audit confirmed that USB and UART ports are disabled during provisioning; JTAG interface physically disconnected as per process flow.")
Evidence Provided
Completed audit checklist
Photographs of provisioning process
Copies of block connection diagrams
Signed vendor confirmation
Test Case Result
☐ Pass – Process fully aligns with vendor’s documented claims ☐ Fail – Discrepancy found between documentation and actual provisioning process
Overall Test Result
(Summarize overall result for BIS-1.1 series — e.g., "All four test cases passed; Secure Debug Interfaces verified and compliant with requirements.")
