One of the ways to organize your network so that it is easier to manage and protect is to segment it into smaller, interconnected subnets. Using a virtual LAN, or VLAN, you can easily and conveniently set up separate subnets, and connect ports from various switches, or even separate buildings, so that they are a part of the same broadcast domain. You can learn more about the virtues of VLAN’s, as well as how to go about configuring them, by watching the Configuring VLAN’s screencast by David Davis on SearchNetworking.com

This blog is titled “Connectivity” because it deals with all aspects and issues of network connectivity. That includes how to ensure your network connectivity is secure and available, and how to make sure that malicious attackers can not intercept or disrupt your network connectivity. Do you know what ARP Poisoning is? How about a multicast storm? Have you heard of Spanning Tree Protocol or VLAN Trunking Protocol hacks? Do you know how to protect your network from them? Networkworld.com recently hosted a chat session with Christopher Paggen and Eric Vyncke, authors of LAN switch security: What hackers know about your switches, which covers a wide range of security issues and the authors’ advice and tips for how to lock your network down and protect against these (and other) threats. Read LAN switch security: what the hackers know that you don’t to see what the authors have to say.
