<p><strong>Understanding IoT Security</strong><br />
The Internet of Things (IoT) refers to everyday physical devices connected to the internet. From smart thermostats and wearables to industrial sensors, these devices improve convenience and efficiency&mdash;but they also introduce major security risks.</p>

<hr />
<p><strong>Why IoT Security Matters</strong></p>

<ul>
	<li>
	<p>IoT devices often lack robust built-in security features</p>
	</li>
	<li>
	<p>They&#39;re a growing target for hackers due to weak authentication and outdated firmware</p>
	</li>
	<li>
	<p>A compromised IoT device can act as a backdoor into larger networks</p>
	</li>
	<li>
	<p>Many devices collect sensitive personal and operational data</p>
	</li>
</ul>

<hr />
<p><strong>Common IoT Security Risks</strong></p>

<ul>
	<li>
	<p><strong>Weak default passwords</strong>: Many devices ship with factory settings easily guessed or never changed</p>
	</li>
	<li>
	<p><strong>Lack of firmware updates</strong>: Vulnerabilities go unpatched</p>
	</li>
	<li>
	<p><strong>Unencrypted communications</strong>: Data in transit can be intercepted</p>
	</li>
	<li>
	<p><strong>Insecure APIs</strong>: Poorly secured interfaces can expose device control</p>
	</li>
	<li>
	<p><strong>Device cloning and spoofing</strong>: Attackers can replicate or impersonate devices</p>
	</li>
	<li>
	<p><strong>Botnet recruitment</strong>: Devices can be hijacked to participate in massive DDoS attacks</p>
	</li>
</ul>
