Join Greg Sowell for an in-depth discussion in this video Basic router security, part of Networking Foundations: Network Media (WANs).
- [Voiceover] Protecting network devices…is just as important as protecting servers and PCs.…Step one is securing a remote administration.…Administrators remotely connect to the network…equipment to fix issues.…Access should only be allowed via secure methods…like SSH for CLI or HTTPS…for browser-based administration.…Insecure or unused protocols…like Telnet and FTP should be disabled.…When logging into equipment,…a centralized authentication system…should be employed when possible.…
A centralized authentication server like RADIUS…allows for unique user names to be used by employees…and can also keep track of entered commmands.…Most devices have a login password retry limit…for each device, which should be employed when possible.…Only specific IP ranges should be allowed…to connect to devices from mode administration…and statistics gathering with simple…network management protocol.…Limiting admin access to specific subnets…and specifying an IP address range…for VP and administrators…will severely limit potential attack vectors.…
He discusses different WAN technologies and features such as speeds, spans, and price points—including inexpensive options such as VPN. He then covers switches (the devices that connect computers in your building) and routers (devices that control the transmission of network data). Along the way, Greg shows how to build private connections, implement free networking over the Internet, build switch networks, and overlay-routed networks. He'll also introduce different routing protocols, such as OPSF link-state routing and distance-vector routing with RIPv2, EIGRP, and BGP.
Note that this course maps to domains 1 and 2 of the Microsoft Technology Associate (MTA) Networking Fundamentals certification exam (98-366).
