IoT Security Overview

Why IoT “must” be secured.

While using the IoT to the maximum benefit, organisations fail to realise that they are connecting “things”, many of which were never designed with security in mind because their purpose did not need it. IoT provides ease of connectivity, thus providing different attack surfaces to hackers within the system. At times, the network finds it difficult to identify all the devices that are connected in the IoT system, and the devices that are communicating, thus giving easy access to the system. With the increase in the endpoints within this system, there is an exponential increase in the amount of confidential data flowing within the system. This is reason enough to realise the value of this information and the necessity for the security of an IoT infrastructure.

How can SecureLayer7 help?

SecureLayer7’s comprehensive IoT Security Service lets you focus on building your product your way and takes care of the security of the complete IoT ecosystem in a holistic way. From design to lifecycle management, from superficial automated testing to in-depth manual assessments, and from endpoints to networks to the cloud, we have you covered. What makes us different is our approach in which the customer’s pressures are kept in mind, and delivering our services such that the time of delivery is not at all hampered.


SecureLayer7 engineers perform the security assessment on physical device interfaces to identify security threats, such as IoT device exploitation, and encryption keys, prioritising the risk at the device level and providing actionable mitigation steps.


SecureLayer7 engineers test device network services in-depth to find potential vulnerabilities, such as reply attacks, lack of payload verification, Unencrypted Services, and various injections. We also provide you with actionable mitigation recommendations.


When the SecureLayer7 security engineering team starts with web / mobile interface security assessment, they make sure that they uncover critical software vulnerabilities and prepare the working POC to demonstrate weaknesses in the application with actionable recommendations for mitigation.


SecureLayer7 engineers perform security testing on cloud services, which can be accessed externally. The cloud API is used to interact with IoT devices and sensors. SecureLayer7 prepares the actionable POC to demonstrate the vulnerabilities, and it provides working recommendations to mitigate them.


A very important part of the firmware security assessment is to analyze firmware, to make sure that a minimum baseline is maintained, and that hard-coded plain text passwords, encryption keys, and backdoored accounts are not present. SecureLayer7 is not limited to checklists, as it has its own approach for assessing the firmware.


In the wireless protocol security assessment, SecureLayer7 engineers perform security testing on the wireless protocols that are used for device communication. They do extensive research on Bluetooth LE, RF analysis, ZigBee, and 6LoWAPN. They also follow the minimum baseline standards for the device communication protocol.

SecureLayer7 accredited with certifications such as CERT-in and ISO 27001. CERT-in enables to certify the security audits for Government, the BFSI customers. SecureLayer7 provides testing and reporting to support application security compliance against PCI, HIPAA, SOC type 1 and type 2 and other regulatory requirements. SecureLayer7 can customise scanning reporting templates to support internal standards and other regulatory requirements.

SecureLayer7 Service and Deliverables


Vulnerability identification in your system along with the knowledge of major areas of exploitation is critical. However what is more important is to convey all this information in a simple and concise way. This report includes all the information of the security controls assessed in the scope as well as an analysis of the areas that need to be checked for achieving the required amount of security.

The report is systematically designed into two parts: The high level management report suitable for the understanding of management personnel, and an in-depth technical document for the technical staff to understand the underlying security risks along with recommendations and preventive countermeasures.
