The idea of Internet of Things (IoT) aims at connecting physical objects to the internet and permits them to provide totally different services to communicate among various objects. In this way, IoT connects each device to provide a universal connectivity. This includes multiple domains and applications like smart home, smart care, transportation etc. Therefore, the extremely dynamic nature of the IoT environment brings new challenges and various service requirements offered to clients.
IoT is an era of “smart” connected products that communicate and transfer an amazing amount of information over to the cloud. With increasing pressure to deliver better services and ensure quick growth and competition, there’s a desire to access, create, use, and share data from any device anywhere in the world. If this is achieved, it will provide greater insight and control over elements in progressively connected lives.
As the IoT proliferates, billions of cloud-connected devices are expected to be designed, manufactured, and deployed over the future decade. During this time of increased connectivity, the world will become hyper-connected; remodeling the lives of people that were seemingly thought impossible earlier. In the coming future, more advanced, smarter cities will be seen where the commuter is automatically radio-controlled. On the bright side, this future is limitless and exciting, but on the other side, it’s conjointly horrifying as well. People have already seen the headlines of how attacks have impacted businesses as well as their valuable data being stolen. It’s widely believed now that the attacks are simply beginning.
Hardware, software, communications, and its protocol, device commission, applications layers, and alternative systems considerations all could impact the security of a device and its data. Therefore, the future of IoT should see security as an integral part of the design and deployment method, and not simply as an after-thought or an add-on.
In order to implement this, security must be architected into devices from the moment of its inception. In addition, it has to be also extended across the supply chain, from security-orientated chips to producing and managing for the lifecycle of the product.
Secure future with IoT security
With the growing challenges of IoT devices, organizations should view security as an essential business consideration and work to enhance their security attitudes at every possible level. By incrementally improving security, organizations can effectively curb their risk of falling victim to cyber disasters. In fact, a company should understand the risks and security necessities and decide how much security they require along with how much capital they require to spend to create a strong system.
IoT security testing
End-to-end testing of IoT applications will guarantee higher consistency, integrity, and measurability, for providing an upscale experience.
- Secure Booting: When power is provided to a device, the integrity of the software on that device is verified through a digital signature in conjunction with the software system authorization to run on it and signed by the entity that approved it.
- Secure Access Control: Device-based access control mechanisms are the same as network-based access control systems like Microsoft Active Directory. Just in case, somebody hacks into a network using company credentials, the compromised information would be limited to the areas approved by those credentials.
The principle of least privilege dictates that only the negligible access required to perform a function should be authorized to minimize the effectiveness of any breach of security.
- Firewalls: The device needs a firewall inspection capability to manage traffic and filter specific data that’s destined to terminate the device in a method that creates optimal use of its limited computational resources out there.
- Updates and Patches: Security patches and software system updates must be delivered keeping in mind the conservation of network bandwidth and also the connectivity of embedded devices.
- Device Authentication: It is a must to attest a device whenever it is plugged into a network — before receiving or transmitting information.
For a seamless operation of IoT devices, it’s vital to have strong security at each level of the device and network levels. This doesn’t need a revolutionary approach, but rather a progression of measures that have proven successful in IT networks, adapted to the challenges of IoT and to the constraints of connected devices.
Secure storage hardware is designed to produce hardware-based, security-related functions. A TPM chip is a secure crypto-processor that’s designed to hold out crypto-graphical operations where it permits a hardware-enabled way to secure cryptographic keys and certificates.
As the IoT landscape continues to evolve and its security requirements shift, an IoT system should be equipped with a solid identity framework from its origin. Secure devices are at the forefront of these efforts. Leading the pack is the Root of Trust which provides secure foundation for IoT devices, platforms, applications, and data analytics.
IoT is about to take the globe by storm. Time is not far when people will be encircled by IoT devices and sensors, calculating every move and predicting future, much like the present day of predictive typing on smartphones. Smart ACs will automatically activate by acquiring GPS data out of users’ mobile devices when they are driving towards home. Smart refrigerators will automatically alert for refilling and vehicles will become more aware and interactive. Smart TVs would be able to synchronize with phone and tablets to understand and put forward favorite TV series.
All these conveniences and smartness would require next level of security, as unauthorized access would bring a smart device down and compromise other endpoints on the network. Smart care devices can particularly be the target of hacking, which can affect operations of an entire health facility and cause threat to patients’ lives. Approaches used for user authentication in the past are inadequate in the IoT era. Biometric authentication can give a seamless authentication experience without compromising user experience.
