Network administrators should also be concerned about the security of switches under their care. In this video, learn about physical security for network switches, the use of VLANs for switched network security, and the use of port security techniques.
- [Instructor] Network administrators should also…be concerned about the security…of switches under their care.…One of the most important security tasks…surrounding switches is maintaining…physical security of the device.…Unlike routers, which are normally centrally located…in secure data centers or network rooms,…switches are generally spread all over the place…providing connectivity at the edge of the network…in every building and floor throughout…an organization's physical facilities.…From a security perspective this can be a nightmare,…because it's critical to keep those switches locked away…where nobody can physical access them without authorization.…
The reason for this is simple.…If someone gains physical access to your switch,…they can take physical control…of that portion of the network.…Earlier in the course you learned how virtual LANs,…or VLANs, may be used to increase the security of networks…by isolating unrelated systems and users from each other.…Switch administrators should implement some common practices…
