For the last week of lecture based class we learned about routers, switches and firewalls.
Switches
- mas MAC addresses to switch ports
- locate physical location of MAC
- contains ARP tables
- MAC address to IP address resolution
- location for the ARP request
- IP address
- Mac address
- age from initial ARP request
- contains CAM tables
- very fast memory
- maps mac addresses to physical switch ports
- very volatile
Routers
- Network topology
- traffic throguh the router
- logged data
- may be compromised
Firewalls
- vast logs
- Connection attempts
- protocols used
- application
- configurable to collect more data
