4 IoT Software Security Tests

Internet of Things (IoT) is a system of interconnected computing devices. Connected security systems, lighting systems and alarm clocks fall under IoT examples, as they are enabled to send and receive data.

Software testing is a fundamental step in any development environment. It is extremely relevant to the IoT market given the complexity of integrations involved in it. However, its importance is not well understood by businesses. A report from the Ponemon Institute claims that only 20% of IoT applications are tested. This means the security of these applications is poor and they are exposed to attacks. It is no surprise that 75% of IoT pilots fail, as revealed by a Cisco survey.Security tests identify data leakages, validate data packets, check corrupt packets, ensure encryption processes and keep a watch over the entire IoT ecosystem.

We list 4 security tests offered by IoT software testing companies to educate our readers on their importance:

Penetration Testing

Penetration testing requires an in-depth understanding of the IoT architecture. Typically, the architecture consists of smart devices, IoT field gateways, cloud gateways, streaming data processor, data storage, machine learning, control applications and client server system. Penetration testing is performed on exposed ports, memory chips and components. Black, white and grey box testing techniques are employed. Lesser resources are required for a test in which an algorithm is present in the embedded system. The tester first verifies if data is encrypted, and next determines if the algorithm is safe in that encryption or requires another level of encryption. Mostly, there is no encryption for battery and memory. Testers can use memory dump to obtain firmware.

Threat Modeling

Threat modeling proactively identifies issues and tackles them during the design process. The system is examined and its structure is assessed. Data flow diagrams breaks the system into a series of processes to clearly outline trust boundaries. Actions are taken against threats such as removing features, warning users and changing design. Threat modeling ensures data remains confidential and is not tampered with.

Web, Cloud and Mobile Interface Testing

Testers look for default credentials on IoT devices during setup. They check for password strength, cross-site scripting and SQL injection vulnerabilities. IoT technologies often use cloud API for product management. Cloud services are assessed by checking all functions and communication between them and other components of IoT. Often remote control services like mobile applications manage IoT technologies. Again, all functions and communications between mobile applications and other components of IoT are tested.

Network Security Testing

The network is the foundation of IoT. Standard network communication paths such as wifi and ethernet create risk. As many connections are simulated as are desired – the number can be in dozens or millions. All exposed ports, misconfigured services within the IoT are identified. IoT application is constantly monitored to obtain quality of experience (QoE) metrics. Breaking points are isolated and network degradations are found. End to end testing may also be performed.

IoT market is expanding rapidly. As market awareness for security grows, the demand for IoT software testing companies will be on the rise.
