12 Tips for Implementing IoT Security12 Tips for Implementing IoT Security

A failure to secure IoT devices could stall the progress of the Internet of things, preventing the technology from fully realizing its vast potential.

Broad Security NeededBroad Security Needed

IoT security needs to span from cloud to end device: any vulnerability affecting many end devices could have a wide impact on the rest of the system or service.

Implement Security at Design TimeImplement Security at Design Time

Security should be implemented in IoT products at design time. It should derive from a system view and be built from a mix of hardware and software features.

Three Types of IoT SecurityThree Types of IoT Security

Security for IoT nodes can mean many different things. We can categorize them into three different groups: Lifecycle security, Communication security, Device security.

Lifecycle SecurityLifecycle Security

Lifecycle security covers the ability to securely and remotely manage the device at different stages of its life, from configuration, monitoring and upgrade, until its decommissioning or revocation.

Communication SecurityCommunication Security

Communication security relates to the measures that should be put in place to guarantee the integrity, authenticity and confidentiality of the link between the device and the cloud.

Device SecurityDevice Security

Device security focuses on the integrity of the IoT node itself, the protection of its resources, data, and behavior over the time of its deployment in the field.

Security Proportional to ThreatsSecurity Proportional to Threats

The security implementation needs to be proportional to the threats the device will face, and also to the estimated cost of a security breach.

Comprehensive Threat AssessmentComprehensive Threat Assessment

A threat assessment needs to be completed and should take the whole system into consideration, including potential side effects.

Make Protection against Scalable Attacks the PriorityMake Protection against Scalable Attacks the Priority

For IoT nodes, protection against scalable attacks—those that can inexpensively be duplicated in other devices—is a priority.

Chain of TrustChain of Trust

Security can be built into a system as a chain of trust, starting with a Root of Trust—a minimal secure domain with dependable security functions, with private access to protected keys. To implement this properly, isolation is key.

Rely on Pre-Integrated SolutionsRely on Pre-Integrated Solutions

Designing a secure product from scratch is time-consuming and prone to security holes. It saves time to rely on pre-integrated solutions that expert teams have verified.

Include Security Evaluation Into Product DevelopmentInclude Security Evaluation Into Product Development

A security evaluation, for example, an external security code audit or white box testing, should be planned into the product development.
