Compliance delivered.
Karamba's security engineers bring decades of embedded systems expertise to two critical pre-deployment services.
TARA and penetration testing are not checkbox exercises – they are the foundation of a defensible security posture.
TARA
Threat Analysis & Risk Assessment.
With connectivity, devices are increasingly exposed to cybersecurity threats. TARA is the structured methodology for reviewing your device architecture, identifying vulnerabilities, and assessing risk before production. It is the required foundation for any compliant security program.
The TARA process – five stages
| Stage | What Happens |
|---|---|
Asset identification | Map all assets in the system – hardware, software, communication interfaces, data stores, and external connections. Establish what has value and must be protected. |
Threat vulnerability analysis | Identify threat scenarios to the cybersecurity properties of each asset. Examine weaknesses in the system and assess whether they could be exploited by a realistic attacker. |
Attack path analysis | Gauge the feasibility of each attack path – attacker expertise required, windows of opportunity, equipment needed. Rate difficulty and likelihood of successful exploitation. |
Risk assessment | Combine impact and attack feasibility to produce a risk rating for each threat scenario. Prioritize findings to focus engineering effort where it matters most. |
Cybersecurity concept | Define the security goals and security requirements that address the identified risks. Work with your team step-by-step to create your cybersecurity concept and mitigation strategy. |
Penetration Testing
Validate Security Before The Product Ships.
Karamba's penetration testing services enable automotive and IoT OEMs and Tier-1 suppliers to validate their product release before start of production. Testing can be carried out on-premise or at Karamba's cybersecurity labs.
Karamba has embraced the continuous pen-testing approach as part of the shift-left practice — starting pen testing as early as the development stage, and integrating automated vulnerability scanning into the CI/CD pipeline.
The testing approaches
| Stage | What Happens |
|---|---|
Gray BoxRecommended | The pen tester is provided with documentation, images, and keys. |
Black Box | Karamba mimics the attack from an external attacker perspective with no prior knowledge. |
White Box | Karamba engineers conduct testing based on extensive source code review. |
The four-stage process
| Stage | Focus | What Happens |
|---|---|---|
Stage 1 | Setup | Examine all relevant documents and understand the target system. Set up the testing environment to simulate relevant attack scenarios. Use TARA findings to prioritize focus areas and critical issues. |
Stage 2 | Fuzzing & interface testing | Send invalid random data into the unit to cause crashes and reveal bug flaws. Conduct vulnerability assessment on the image. Test all in-scope communication interfaces. |
Stage 3 | Reverse engineering | Research the actual binary image of the components. Provides deep understanding of interface testing results. Identifies vulnerabilities in application implementation and security mitigations. |
Stage 4 | Report & presentation | Work closely with R&D teams through weekly status meetings, sharing findings during the development stage. Final report with guidance and remediations best suited to the client's needs. |
Findings Report
Every pen-testing engagement produces a structured findings report:
- Approach and findings overview
- Test methods and tools used
- Details of vulnerabilities found, with severity ratings
- Reproduction instructions for each finding
- Recommended fixes and improvements
- Verification and validation evidence for the assessor
