Security Verification Planning 

Testing begins by linking security requirements and threats to measurable verification methods. 

• Build a security verification matrix mapping requirements to inspection, analysis,testor independent assessment. 
• Define test environments, interfaces, configurations,credentialsand assumptions. 
• Identifynegative, abuse-case and adversarial tests for security-critical functions. 
• Define pass/fail criteria and evidence expectations.
• Prioritize tests based on attack surface,riskand architecture. 

Hardware & Interface Security Testing 

Device testing can include both logical and physical access paths. 

• Assess debug ports, UART, USB, JTAG/SWD and exposed service interfaces where authorized.
• Test boot and recovery interfaces for unauthorized access.
• Analyzememory/peripheral access paths and configuration exposure. 
• Evaluate securitybehaviorafter reset, power cycle, fault and communication interruption. 
• Whereappropriate, assess hardware-assisted controls and physical access assumptions.

Firmware & Binary Security Testing 

Firmware is examined for vulnerabilities, insecure configurations and implementation weaknesses. 

• Perform static analysis and targeted code review where source is available.
• Use binary analysis and reverse engineering where source is unavailable.
• Review authentication, authorization, cryptography, updatelogicand input validation. 
• Assess memory-safety and parser-related vulnerabilities.
• Review hard-coded credentials, secrets, debugfunctionalityand insecure configuration. 

Protocol & Fuzz Testing 

Protocol robustness is a key part of embedded security verification. 

• Develop malformed and boundary-value inputs.
• Test state transitions, message sequencing, authenticationfailuresand replay scenarios. 
• Perform targeted fuzzing of parsers and protocol handlers.
• Monitorcrashes, hangs, memory corruption, unexpected state transitions and resource exhaustion. 
• Correlate failures with root cause and security impact.

Penetration Testing & Exploitability Analysis 

Penetration testing validates realistic attack paths rather than producing only vulnerability lists. 

• Construct attack paths from exposed interface to protected asset.
• Assess authentication bypass, privilege escalation, command injection, insecureupdateand diagnostic abuse where applicable. 
• Validateexploitability and required attacker capabilities. 
• Document affected configurations and reproducible evidence.
• Recommend mitigations and retest after remediation.

Security Regression & Release Testing 

Security testing continues after remediation and across product variants. 

• Retest fixed vulnerabilities using the original exploit or reproducer.
• Perform regression tests around security-critical components.
• Compare release configurations and attack surfaces.
• Validatesecure boot, update, authentication and recovery after firmware changes. 
• Maintainreusable security test cases for future releases.

• What is embedded penetration testing? – It is attack-oriented security testing of the embedded product itself, including hardware interfaces, firmware, protocols, diagnostics, update paths and device services. 
• Do you test hardware interfaces? – Yes, where authorized. Testing can include JTAG/SWD, UART, USB, boot/recovery and other exposed interfaces. 
• Can you test firmware without source code? – Yes. Binary analysis, firmware extraction, reverse engineering and interface-driven testing can be used when source is unavailable. 
• What is protocol fuzzing? – Protocol fuzzing supplies unexpected, malformed, boundary or randomized inputs to identify crashes, memory corruption, state-machine failures and resource-exhaustion weaknesses. 
• How do you prioritize vulnerabilities? – Findings can be assessed using exploitability, attacker prerequisites, affected assets, security impact, exposure and product context. 
• Do you provide remediation support? – Yes. Findings can be translated into technical mitigation recommendations and then retested after implementation. 
• Can testing cover secure OTA? – Yes. Update authentication, signing, manifest validation, rollback, recovery and authorization can be tested. 
• Can the test be mapped to a security standard? – Yes. Test objectives and evidence can be mapped to applicable product security requirements and industry standards.
