<h2>How Can We Improve Security?</h2>
</section>
<section>
<h2>Avoid Problems Repeatedly Seen in IoT Devices</h2>
<ul>
<li>Use SSL for connections to the IoT device or the cloud</li>
<li>Provide mutual authentication between the client and the server</li>
<li>Enforce and use strong passwords</li>
<li>Support 2FA for IoT cloud interfaces</li>
<li>Protect against account harvesting, and implement account lockout</li>
<li>Proper vulnerability management, and actively patch vulnerabilities found or reported</li>
<li>Provide signed or encrypted firmware updates</li>
</ul>
