Xiarch IoT Device Security Testing Services provides security assessment and penetration testing for Internet of Things devices and ecosystems. The service examines IoT products from chip to cloud, covering embedded devices, firmware, wireless communication protocols, web and mobile applications, cloud services, APIs, and backend network infrastructure. The testing methodology includes threat modeling to identify entry points and develop comprehensive threat models throughout the product lifecycle. Device design consulting offers engineers access to information security consultants during hardware design phases. IoT penetration testing evaluates the entire ecosystem including mobile applications, cloud APIs, communications protocols, and embedded hardware and firmware. Hardware testing examines physical security and internal device structure, including component identification, firmware extraction, and identification of audit points. Protocol testing analyzes inbound and outbound data transfers, cryptographic mechanisms, and the ability to intercept and modify transmissions. Firmware analysis extracts and examines firmware content to identify backdoor accounts, injection flaws, buffer overflows, and other vulnerabilities, while also testing software update processes and secure boot cycles. The service also provides root cause analysis formulation for incident response, extracting data from IoT devices for criminal cases and law enforcement investigations. Assessment methodology follows industry standards including OWASP Top Ten and PCI Compliance.
