In the world of internet, soon the Internet of Things is going to be a major possibility for hackers, noting that everything will be connected. Thus it is necessary to ascertain that significant systems and strategies are implemented at every stage of the product development life cycle.
1. Start from the base to reduce attack points
Digital security must be ascertained during every phase of the development process. Crucial part of product requirements and design consideration, security must be ensured at each phase of the development life cycle. The Quality Assurance cycle is an assurance for security as well as functionality while the vital component remains fail-safe systems. It happens when something fails – and failure is going to be there – so it needs to be built to fail safe thus the failure doesn’t lead to a greater systematic failure.
2. Authentication & Authorization
In order to ensure effective communication between devices, the IoT is going to require strong authentication with the usage of techniques such as multi-factor authentication or asymmetric encryption. Each device can be protected with the use of their own unique key. Now it’s practically not right to expect a user to enter a password each time they enter into their car, thus another form of security is required. Thus certificate-based authentication works best. Besides, authorization is also imperative as strong authorization stands for role-based access controls that can be enforced to limit exposure.
It’s necessary to encrypt sensitive personal data that you have stored on a device and every kind of communication that takes place to and from the device should be encrypted in transit with the use of secure protocol. Besides key management is crucial so that when someone access a device must not be able to extract data. Thus the actual key protecting data should be protected.
The transparency must be maintained in regard of the type of data that is collected, how it is used as well as opt-out options. The personal data collection needs to be limited to only which is essential. In other words, you should protect only what needs to be protected to reduce exposure.
5. Consumer Awareness
Consumers are also responsible for IoT security but as professionals, by creating consumer awareness. Now for instance, credit card companies send constant notifications to consumers via alert warnings and best practices to share credit card information. With the sharing of information, consumers are empowered and they can contribute in an organization’s efforts to prevent fraud.
Often we come across companies not investing in security and this leads to major loss of consumer confidence, falling stock prices and major organizational shake-ups. Meanwhile, IoT involves higher risk, still as presently we are in the early stages so it’s easy to design a comprehensive security program to protect against threats that we may face in future.
