IoT Security

The Internet of Things (IoT) is seeing the rapid rise but it seems to repeat the history of technology evolution. The pace of growth is not matched with security requirements. IoT helps automation as well as real-time synchronization of business processes. The implementation helps for precise response in real time.

 “IoT devices assist businesses in real-time responses to supply-and-demand market effects, they empower patients and healthcare professionals to continuously monitor conditions, and they enable electric grid operators to adjust the production, flow, and cost of electricity according to real-time market demands to ensure the most efficient, resilient, and cost-effective solution,” says James Scott, senior fellow at the Institute for Critical Infrastructure Technology, a Washington DC-based cybersecurity think tank.

Hundreds of companies now provide IoT solutions. But security aspect is lagging behind.

 “As was shown in the Dyn attack, we appear doomed to repeat the mistakes we made with PCs and mobile devices in IoT,” says Tom Byrnes, founder and CTO of ThreatSTOP. “Once again, cost reduction has made security an afterthought, if a consideration at all, with predictably disastrous consequences.”

 It is different than other systems as threat involved is higher due to many connection points. As per the Intel, 200 billion IoT devices will be online by 2020.

 “Most IoT devices and sensors lack any form of security or security-by-design,” says Scott.

 “Without layered security of the IoT microcosms, hacktivists can disrupt business operations, cyber-criminals can compromise and ransom pacemakers, and cyber-jihadists or nation-state sponsored threats can compromise and control the grid,” to name just a few of the potential IoT security attack scenarios.

“Every IoT device has inherent vulnerabilities and exploitable weaknesses resulting from a culture that sacrifices security in the design process in favor of meager savings and in the rush to market,” says Scott. “The overwhelming preponderance of insecure IoT devices in the future will render security an impossibility in the future.”

 Most of IoT devices do not have computational power or battery life to have security applications.

 “We need to develop cost-effective IoT devices that incorporate security-by-design rather than cheaper and less secure alternatives,” says Scott. “While that may save a few dollars in the short-term, it puts the public and critical infrastructure at risk of losing millions of dollars and valuable data in the long-term.”

 Also, there is lack of platform standards.

 “With old devices lasting longer than ever before, there are many devices currently in use that do not support new standards,” says Sam Rehman, Chief Technology Officer of Arxan. “Hackers will always see legacy devices as a prime choice of entry.”
