A team of security researchers has demonstrated exactly the same by developing a new hacking technique called <b style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">Funtenna</b> that uses sound and radio waves to siphon data from computers even without Internet access.</div>

The malware overtakes the control of the electronic circuit of the device (general-purpose input/output circuits) and vibrates them at a frequency (which transmits radio signal) of the attacker's preference.</div>

An attacker then can pick up these signals using an AM radio antenna (Funtenna) from a short distance away.</div>

"You have network detection, firewalls… but this transmits data in a way that none of those things are monitoring, this fundamentally challenges how certain we can be of our network security," <a href="https://www.rt.com/usa/311689-funtenna-hacking-sound-waves/" rel="nofollow" style="border: 0px; color: #3d5a99; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: bold; line-height: inherit; margin: 0px; outline: none; padding: 0px; text-decoration: none; vertical-align: baseline;" target="_blank">said</a> Cui.</blockquote>

For secure communication among the IoT devices, many security mechanisms and protocols have been implemented, including:</div>

As it is evident, Security solutions for embedded devices connected to the Internet is also necessary. The devices also need to be secured from attacks like eavesdropping, DDoS and tampering of network traffic.</div>

For SSL/TLS implementation in IoT devices, INSIDE Secure has introduced a new open source embedded SSL called <a href="http://www.matrixssl.org/" rel="nofollow" style="border: 0px; color: #3d5a99; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: bold; line-height: inherit; margin: 0px; outline: none; padding: 0px; text-decoration: none; vertical-align: baseline;" target="_blank"><u style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"><b style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">MatrixSSL Tiny</b></u></a> as an extension to MatrixSSL - a source for web servers to implement encryption layer for secure management of remote devices.</div>

MatrixSSL Tiny is going to be demonstrated this week at Black Hat conference in Las Vegas, where the security researchers will be representing its full suite of security products and will talk about its solution for cyber attacks focussed at IoT.</div>

MatrixSSL Tiny is a lightweight TLS software implementation for IoT devices with limited memory to make secure communications among them, yet demand more robust security to prevent eavesdropping and tampering of network traffic.</div>

The software also performs real time functions that nulls the memory on completion of a particular session. According to researchers, MatrixSSL Tiny is the world’s smallest, yet powerful IoT security solution.</div>

Why SSL is Not Sufficient?</h3>

<div style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
Despite developments for enhancing the security, IoT infrastructure is still massively prone to cyber attacks that lead to offer open gateways for people with malicious intents.</div>
<div style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">

Any command initiated on a smart device, be it an application or a firmware, must be verified through a chain of trust.</div>

<div style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
If we consider a situation, where communication is taking place on a traditional IT system and an IoT smart device, we see that IT systems follow a layered security procedure; whereas in IoT smart devices authenticity and confidentiality can be tampered with.</div>
<div style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">

<div style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">
Therefore, multi-layer security measures are needed for IoT devices too so that the IoT devices could differentiate that the information received or sent is by an authorized user or an intruder.</div>
