Designing a network that works and is easily maintained is simple, but so is designing one that increases security. Many I.T. employees shoot for simplicity because the bosses need the systems up and running yesterday and the I.T. department is usually under staffed. The big issue with simple designs is that it is also simple for bad actors to traverse the network. All too often, network administrators use "flat" network and then segment by "virtual local area networks" (VLANs). The issue with this is that the ease of jumping from one VLAN to another takes little time and with free tools, one could do so in minutes. Doing so will give that threat access to any device. There is much more to write about, virtual private connections (VPNs), access control lists (ACLs), port security, changing the default VLAN, black-hole VLANs, 802.1x authentication, and so much more.
