1.4 Network Device Security Flashcards
This network device replicates traffic onto all ports with minimal security.
Hub
This legacy network device maintains track of network addresses, segments traffic, and breaks up collision domains. It connects network segments.
Bridge
this network device provides micro-segmentation with each port receiving traffic for the appropriate host using the MAC address.
Switch
This network device connects networks together and determines the path a packet will take over a network.
Router
This network device makes its decisions by evaluating MAC addresses.
Switch
This network device operates by evaluating IP addresses.
Router
This network device is often used to connect IoT devices to traditional IP based networks
Bridge
The physical hardware-based address of a network interface card. Used by switches to direct Network traffic.
MAC address
This is the layer of the OSI model that Mac addresses operate on.
OSI layer 2. Data link layer.
This is the layer of the OSI model that IP addresses operate on.
OSI model layer 3. Network layer.
The first half of a MAC address. 24 bits or six hexadecimal characters.
OUI - organizational unique identifier. The hardware manufacturer.
IP addresses consist of these two parts:
Network identifier and unique host identifier.
This protocol is the method used by a host to determine the MAC address of another on a local network.
ARP - address resolution protocol
The location where an ARP reply is stored for a period of time before sending another ARP request.
ARP cache or ARP table
The capability of observing, recording, and analysis of traffic as it transits a network.
Sniffing
