Let’s start with a shocking fact: out of 400 illegitimate access attempts into IoT devices, 66% are successful. The explosive growth of the Internet of Things is positively inching towards $ 6 trillion investment by 2021 while the increasing cases of external attacks are a matter of concern among the community. According to Nazario, IoT devices are probed 800 times every hour by hackers across the globe.
As recommended by The Federal Trade Commission, IoT service providers must conduct a risk assessment of applications in the design phase to ensure thorough data safety checks. Moreover, Microsoft suggests not extending hardware requirements, equipment must be tamper-proof, and a reliable platform module must implement that boot functionality.
There are, in fact, many voices to support the alarming state of IoT followed by thinned profits. Here’s what IoT service providers must do assuring a well-fortified data transmission.
Follow Code Obfuscation
Obfuscation makes it troublesome for hackers to understand the application code and reverse engineer it. In fact, any attempt to de-obfuscate requires more processing effort, and no hacker would buy that.
Enterprises that have to deliver the code backing their intellectual property for public execution must go for a Binary Code Obfuscator that accepts a source code file and returns a functionally equivalent file that is difficult to decipher. Other techniques could be Data Obfuscation that includes converting static data to procedures, splitting variables, modify encoding, etc. Without tampering the code’s original logic, Control Flow Obfuscation changes the logical flow by adding misleading conditional statements, making it more difficult for compilers to extract logic.
Not to miss, the masked code assists in tracking illicit copied supplied to multiple users and the source that initiated the activity.
Given the high vulnerability of DevOps toward risk, Code Obfuscation is the first thing developers must think of, for operating systems and communication protocols like APIs across the IoT network.
Given the complexity associated with the DevOps network, monoliths tend to develop with time while scaling individual features becomes unfeasible. That is, any update required will impact the overall application. Thus, it is essential to go Agile, reduce throughput times, and achieve rapid changes on the smallest units. By empowering the SOA network with such agility, Micro services break down tasks into smaller standalone services communicating via APIs to make repairing of built scripts and configurations hassle-free.
In a Micro services landscape, many different micro services are handled by autonomous teams who choose the most suitable resources (technology, skill sets, etc.) within the scope of their small project while entirely ignorant of what other services are doing. Besides letting you iterate quickly, the entire solution can be assembled seamlessly followed by development performed in lesser sprints. Thus, the production is always inching closer to finishing while lowering risks in output at every stage.
As a part of best practices, Microservices must be monitored for response time notifications, service error notifications using logs such as Splunk, AppDynamics, and others. Not to miss, there should be a dedicated data source for every microservice. So, for every new or modified code, create a new microservice and reserve the existing as it is until you have tested the former.
Do more than just updating Firmware
According to the Security Research for DevOps by Carnegie Mellon University, more than 40% of 2000 home routers firmware images were found under threat to attacks.
Firmware is a dependable security layer but vulnerable to successful infiltration too. While focusing more on design, enterprises miss out on protecting the protection of the IT solution. More than just having a Firmware update policy; its high time businesses prefer a secure one. Based on your IoT network, scale and reach, different Firmware update techniques are available. Firmware over the Air (FOTA) is the newest mechanism to transmit updates to a mobile device with ‘Air’ as the interface, that is, through Radio Frequency Communications. For ensuring leaner transmission, Binary Patching is useful; transferring a patch with only the differences between the update server and the network device.
While a robust Firmware update policy works well, monitoring the Firmware Bootloaders regularly for they are the hardest to defunct. Disable all functionalities that are inaccessible to the user such as Telnet and JTAG. Turn off all unused debug interfaces and disable consoles for access at the user end.
Consumer contribution in this regard is of enormous significance. Not accepting weak passwords, suspending accounts after too many failed attempts and mandatory 2 Factor Authentication are some of the highly effective methods. IoT buffers volumes of data amongst devices in real time and enterprises, especially in Insurance and Automobile are burning the midnight oil to ensure high-quality products, better services with a lower risk to the manufacturer.
HP warns 70% of IoT deployments are unsafe; hinting at the DevOps that are still in their infancy and deserve all attention steered towards them.
