<h2 class=”section-title”><i class=”icon” data-icon=”1″></i>Why network mapping is important</h2>
<p>Network mapping is a critical <a href=”https://www.techtarget.com/searchsecurity/tip/How-to-develop-a-cybersecurity-strategy-Step-by-step-guide”>component of cybersecurity</a> and general operations. It helps admins detect unauthorized devices and identify devices that might not receive updates, be misconfigured or unnecessarily expose vulnerabilities.</p>
<p>Visualizing a network gives admins a way to understand how devices relate to each other and how network traffic flows through them. The goal is to achieve greater optimization and more efficient troubleshooting.</p>
<p>Network mapping also underpins effective incident response and disaster recovery. The maps display the paths between components, enabling admins to build in redundancy or create new connections if the originals fail.</p>
<p>Admins often use Netdiscover in conjunction with other utilities, such as <a href=”https://www.techtarget.com/searchnetworking/tip/How-to-use-Nmap-to-scan-a-network-for-documentation”>Nmap</a>, <a href=”https://www.techtarget.com/searchnetworking/tutorial/Examine-a-captured-packet-using-Wireshark”>Wireshark</a> and NetHogs, to provide a complete picture of the network infrastructure and the data flow within it.</p>
