Methodology

Methodology of IoT security testing

• 

  1.IoT penetration testing
  

  In IoT penetration testing, a form of IoT security assessment, security experts uncover and exploit security vulnerabilities present in IoT devices. The security of your internet of things (IoT) devices is check in the real world with internet of things (IoT) penetration testing. Under this, exactly, we mean assessing the comprehensive internet of things (IoT) system, not just the device or the software.

  2. Threat modeling

  Threat modeling is a structured approach for identifying and cataloguing potential threats, including vulnerabilities in defences or their absence, and for prioritizing security measures. It pursues to give the protection force and security team an examination of the security panels required built on the current information systems and risk environment, the most likely attacks, the target system and their methodology.

  3. Firmware analysis
  

  Recognizing that firmware constitutes software, akin to computer programs or applications, is one of the most fundamental concepts to understand. The use of firmware on entrenched devices, which are tiny computers with particular usages, is the only division. A router smartphone or even a heart monitor, as examples, the procedure of removing and testing firmware for entrances, buffer overflows, and other security flaws is known as firmware analysis.

Our approach overview

• 

  Scope Comprehension
  

  Penetration testers must understand the scale of the target. Scope is defined by constraints and limitations. Prerequisites for penetration testing vary depending on the product. As an outcome, the tester must understand the possibility and progress arrangements in agreement with it in the initial stage of an internet of things (IoT) pen test.

  Vulnerability Evaluation and Exploitation

  In this phase, the tester attempts to compromise the IoT device by leveraging any vulnerability identified in previous steps. Once more, hackers have myriad methods to exploit the target. Amongst them are: JTAG Reverse Engineering for Firmware Bug Fixing Sensitive values are hard-coded and exploitation with I2C, SPI etc.

• 

  Attack Surface Cartography

  The tester maps out the attack surface of an IoT device to illustrate every potential entry point an attacker could utilize to gain access to the system. In accumulation to classifying all possible access points for an attacker, the attack surface mapping procedure also involves sketch a very thorough construction diagram.

• 

  Documentation and Reporting

  In this step, the tester is required to generate a comprehensive report encompassing all technical and non-technical summary information. The tester must also deliver all the code snippets, demos, proof of concepts and other resources that they exploit during the procedure. Sometimes after a virus has been fixed, the tester must revaluate it.
