Testing reveals that the tracker has a Joint Test Action Group (JTAG) port on the circuit board that can be used to overwrite the firmware on the tracker and provide false location data. Which two Internet of Things Security Foundation (IoTSF) Best Practice Guidelines ( BPGs) should this company follow in its design process to ensure security from these forms of attack? Choose 2 answers. 1. Device secure boot 2. Credential management 3. Physical security 4. Application security A) 1, 3 B) 1, 2 C) 2, 3 D) 3, 4 A A compa ny develops an IoT -based security system. The system uses proximity sensors that communicate with a central gateway using a 433 MHZ radio signal. Testing reveals that the traffic can be sniffed with a software -defined radio, and an attacker could spoof the proximity sensor by copying the authentication details from the radio traffic. 4 | P a g e Which Internet of Things Security Foundation (IoTSF) Best Practice Guideline (BPG) should this company follow in its design process to ensure the security of the radio data? A) Device secure boot B) Physical security C) Network connections D) Application security C A company hosts a database in a public cloud. Multiple IoT devices are compromised and used to generate a high volume of requests targeting the database to affect i ts availability. Which type of attack is this? A) Cross -site scripting B) Distributed denial of service (DDoS) C) Spear phishing D) Structured Query Language (SQL) injection B A company developed an IoT smart photo frame that allows users to upload photo s to their device using a web browser. Testing revealed that users can upload files onto the root filesystem. Which Internet of Things Security Foundation (IoTSF) Best Practice Guideline (BPG) should this company follow in its design process to ensure fil esystem permissions are set correctly? A) Device secure boot B) Physical security C) Secure operating system D) Application security C A company uses IoT devices to capture data in the field and transmit it for central processing. The company plans to fol low the Internet of Things Security Foundation's (IoTSF) Best Practice Guidelines (BPGs) to ensure that personal data is protected. Which IoTSF guideline should this company use? A) Device secure boot B) Physical security C) Securing software updates D) Application security
