Protocols
This layer 7 protocol is a naming system for computers, services, or other resources connected to the internet or private network. Runs on port 53
What is DNS (Domain Name System)?
This layer 3 networking device forwards data packets between computer networks. They perform the traffic directing functions on the internet. A data packet is typically forwarded from one of these to another through networks until it reaches its destination node.
What is a router?
This is the wireless frequency in which the 802.11b, 802.11g, 802.11n, and 802.11ax standards run.
What is the 2.4GHz frequency?
What is a hypervisor?
This is a networking model that defines how data gets from a source to a destination.
What is the OSI (Open Systems Interconnection) model?
This layer 7 protocol is a network management protocol that is used on TCP/IP networks where a server dynamically assigns an IP address and other network configuration parameters to each device on a network to communicate with other IP networks. It runs on port 67 and 68
What is DHCP (dynamic host configuration protocol)?
This piece of layer 2 hardware is a bridge between a wireless and wired local area network and can be a central point for a wireless access network
What is an access point?
This is the frequency in which the 802.11a, ac, and ax standards run.
What is the 5GHz freqeuency?
This piece of software is a graphical desktop sharing system that uses RFB protocol to control another computer remotely.
What is VNC (virtual network computing)?
This is a property of access control of multiple related yet independent software systems. With this property, a user logs in with a single ID and password to access a connected system or systems without using different usernames or passwords. Some configurations seamlessly sign on at each system.
What is SSO (single sign-on)?
This layer 4 protocol is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems on the internet. It makes routing decisions base don paths, network policies, or rulesets configured by a network administrator. It also makes core routing decisions.
What is BGP (border gateway protocol)?
This layer 3 and 4 hardware device or piece of software filters incoming and outgoing traffic, using mostly ports and protocols as filters for that traffic.
What is a firewall?
This mobile broadband access technology that downloads data at up to 10Gbps.
What is 5G?
This cryptographic network protocol operates network services securely over an unsecured network. It runs on port 22.
What is SSH (secure shell)?
This is a network of physical devices, vehicles, home appliances, and other items embedded with electronics, software, sensors, actuators, and connectivity that enables these objects to connect and exchange data.
What is IoT (internet of things)?
This layer 2 and 3 communication protocol is used for discovering the link-layer address, such as a MAC address, associated with a given network layer address, typically an IPv4 address.
What is ARP (address resolution protocol?)
This is a common layer 2 encryption standard for wireless networks; it also has an enterprise version that uses a RADIUS server for authentication.
What is WPA/WPA2 (Wi-Fi Protected Access)?
This mobile broadband access technology downloads data at up to 150Mbps.
What is 4G?
This layer 7 protocol is an internet standard protocol for collecting and organizing information about managed devices on IP networks and modifying that information to change device behavior. It runs on port 161.
What is SNMP (simple network management protocol)?
This networking principle states that people have the permissions they need on resources to get their jobs done and no more.
What is the principle of least privilege?
This layer 7 protocol provides centralized authentication, authorization, and accounting management for users who connect and use a network service. Often used by ISPs and enterprises to manage access to the internet or internal networks, wireless networks, and integrated email services.
What is RADIUS (remote authentication dial-in user service)?
This is a list of permissions attached to an object on layer 2, 3, or 4. It specifies which users or system processes are granted access to objects and what operations are allowed on given objects. Each entry specifies a subject and an operation.
What is an ACL (access control list)?
This cellphone technology downloads data at up to 0.375Mbps.
What is 3G?
This layer 7 protocol is mainly used for providing shared access to files, printers, serial ports, and miscellaneous communications between nodes on a network. It also provides an authenticated inter-process communication mechanism and can run on ports 445 (or 137 through 139 when part of NetBIOS).
What is SMB (server message block)?
This term in networking can be defined as "ensuring data is not altered in any way, shape, or form as it goes from a source to a destination."
What is integrity?
