<p>Network security in On-Premise and Cloud is one of the most important moments for safe and correct working of the computer systems and networks. </p>



<p>There are few types of network security devices:</p>



<ul class="wp-block-list"><li>active devices &#8211; firewalls, antivirus scanning devices, content filtering devices, which block the surplus traffic;</li><li>passive devices, such as intrusion detection appliances, which identify and report on unwanted traffic;</li><li>preventative devices &#8211; penetration testing devices and vulnerability assessment appliances, which scan the networks and identify potential security problems;</li><li>Unified Threat Management (UTM) devices, such as firewalls, content filtering, web caching, which serve as all-in-one security devices.</li></ul>



<p><br><strong>With regard to network-based controls, consider the following network security devices and elements. </strong></p>

<p><strong>Must have Cloud Security Features</strong></p>
