Security as a Top Priority in the IoT Era

One of the biggest knocks against IoT devices is, 'what happens if they get hacked?' So, what can developers do to secure these devices?

Security needs to be addressed in every part of the IoT system, whether we are talking about hardware, connectivity, backend software and databases, or post-market service. That is why IoT companies should minimize these potential problems by implementing security at the design stage. It should include creating hardware-based security, developing authentication and access control and secure APIs, guaranteeing safety and quality assurance, evaluating security architectures.

Securing the Device and Data in Transit

Naturally, some form of security must be built in at the manufacturing level. Endpoint security is often focused on, but these mass flows of data must also be secured during transport as a new priority. Sensors collecting data and sending them to the cloud could leave communication channels and hardware security at risk, as data is more vulnerable when it is in transit. The lack of encrypted communication makes device susceptible to third parties, allowing them to access data that is sent over the network. The focus is on building robust architectures by adding protocols, hardware security models, trusted execution environments, trusted platform modules, SEs, repurposed secure microcontrollers, etc.

Securing the Database and Addressing Privacy Issues

Another major component of the security puzzle that demands to be addressed is the privacy of the data stored in databases. IoT developers need to understand potential security threats and address them to ensure that companies’ data, or that of their customers, is not compromised. Privacy concerns are already a core issue with cloud systems, and this will grow as IoT becomes mainstream. Objects will continually be collecting and aggregating data in real time, which must be stored securely for reporting and review.

Securing the Application

Applications serve as an excellent source of data, providing users an insight that could make their businesses more relevant and beneficial. It is also a source of numerous attacks. The most common vulnerabilities are injection flaws, broken authentication, cross-site scripting (XSS), insecure direct object references, and security misconfiguration. IoT developers should decide which security feature to include in further development, and it depends on several factors: availability of software development tools, type of hardware, and OS. Implementation of a secure software development lifecycle and secure coding is the best way to go in the application development process.

Securing the Lifecycle Management

Companies which decide to embrace IoT will require their IoT systems to be operative for many years, during which they will expect continual monitoring and upgrading. Developers are faced with a challenge - they must have a detailed plan for the whole lifecycle, from the design stage, through deployment, management and, eventually, decommissioning. For a buyer, this means assurance that security can be regularly monitored and updated appropriately (when a new vulnerability is detected, patches can be pushed). To build a sustainable security lifecycle management framework, you need to include security services within it: secure communication and storage, key generation and administration, authentication and identification, and credential/device lifecycle management.


In a nutshell, there is no doubt that security is a must in the Internet of Things era. It has to be implemented in every part of the IoT ecosystem - from hardware to end-user applications. Adopting a secure IoT solution enables relevant market insights and the maximization of resources while protecting your data and infrastructure assets.
