IoT penetration testing can help avoid such incidents to increase your business productivity.


What security aspects can you avoid to strengthen your IoT defense, as per OWASP?

Various IoT device developers and customers rely on the OWASP Internet of Things project’s Top 10 security list to comprehend pressing issues related to IoT security. It supports entities in the endeavor of assessing IoT technologies adequately and enabling more resilient security structures.
As per the latest available list, the OWASP top 10 IoT security concerns include the following:

  • Use of easily guessable, weak, or hard coded passwords
  • Lack of secure network services
  • Inadequate security for ecosystem interfaces
  • Deficiency of secure IoT device update mechanism
  • Presence of outdated components
  • Lack of suitable privacy protection measures
  • Insecure data storage and transfer
  • Absence of device management policies
  • Security issues in default settings
  • Improper physical handling


What approach do pentesters widely adopt for conducting IoT penetration tests?

The IoT pentesting methodology encompasses the following phases

Phase-1 Defining the scope
The pentesting team first determines the scope of the test arrangement as per the client’s need. It ultimately depicts the cost, efforts, goals, and technical procedures involved with the IoT penetration test.

Phase- 2 Attack surface mapping
This phase of attack surface mapping involves defining the entry and exit zones that adversaries can misuse. The pentesting team develops a map as per their understanding of the IoT device solution and its security architecture. Usually, the IoT device architecture covers three categories:

  • Firmware, software, and applications
  • Embedded device
  • Radio communications


Phase-3 Vulnerability assessment and exploitation
Once the testers have their detailed security architecture diagram, they evaluate the vulnerabilities of different IoT device components. Each of the IoT architecture categories of embedded device, radio communications, and software applications have its own forms of vulnerabilities. After the testing team has identified the exposures, they utilize the tactics and tools akin to actual adversaries to sabotage IoT security. IoT devices consist of various interfaces. Hence, command injection, code injection, and input validation are usually some of the focal points of the attack. Testers also conduct post-exploitation measures to leave no stones unturned in finding the misconfigurations in the IoT device solution.

Phase-4 Documentation and reporting
At this final stage, the pentesting experts list out all discovered vulnerabilities and share them with the client’s management. They communicate at length all possible remediation measures in the report to upgrade the IoT security posture.


What is SCADA, and how might it be relevant to sustaining your entity’s cybersecurity posture?

SCADA or Supervisory Control and Data Acquisition system denotes a real-time device monitoring and controlling framework. The access to quick and resourceful data with SCADA allows all types of organizations globally to initiate data-driven measures for process improvisation. SCADA has been in existence much before the dawn of IoT, and it has benefitted numerous industries, including manufacturing, waste treatment, and telecommunication. While SCADA systems focus on regulating and monitoring different machinery, IoT emphasizes machine data analysis to improve productivity and business profitability. SCADA usually functions as MOM (Message-oriented middleware) or IoT gateways that help businesses connect various devices across many websites to fetch data on a single platform.
Despite the emergence of IoT, many business organizations continue to use SCADA software systems or a combination of both IoT and SCADA. Thus, it is essential to conduct comprehensive penetration testing for such entities to secure their IoT solutions and SCADA systems. Many highly recommend implementing extensive security best practices under the guidance of penetration testing professionals for SCADA software and IoT architecture.
