It is a private connection that is meant to be accessible only to an organization and its members and people who have authority within it.
Intranet
Every computer on a network is called?
Host or End Device
Two types of Network Threats
Internal & External Threats
True or False:
The study of network security shouldn’t start with a clear understanding of the underlying switching and routing infrastructure.
False
An Inexpensive low-bandwidth option with the use of a modem.
Dial-up Telephone
A high bandwidth Internet data that is provided by a
cable television service provider.
Cable
It is the physical security of network devices and preventing unauthorized access to the devices
Network infrastructure security
A type of cloud built to meet the needs of a specific
industry, such as healthcare or media. It can be private or public.
Custom Cloud
a worldwide collection of interconnected LANs and WANs.
Internet
Diagrams illustrate devices, ports, and the addressing scheme of the network.
Logical Topology
This Network Infrastructure uses the same set of rules
and standards.
Converge Network
Communication across a network is carried through a ____ which allows a message to travel from source to destination.
Medium or Network Media
It allows us to store personal files or
backup our data on servers over the internet.
Cloud Computing
Reserved circuits within the service provider’s that
connect distance offices to private data networking.
Dedicated Leased Line
It is useful when wireless access points cannot reach all the devices in the home. In other words, it is like an extender.
Powerline networking
assurance of timely and reliable access
to data for authorized users.
Availability
A network that carries data to multiple devices over the same network infrastructure.
Converge Network
It splits traffic into packets that are routed over a network, and each packet could theoretically take a different path to the destination.
Packet switching
What are the computers that provide information to end devices?
Server
It interconnects end devices. Examples include switches, wireless access points, routers, and firewalls.
Intermediary Devices
Businesses Internet Connections
Dedicated Leased Line, Ethernet WAN, Business DSL (SDSL), Satellite
assurance that the data has not been
altered during transmission.
Integrity
What are the Security Solution for Small Office Network?
● Anti virus and anti spyware soft ware
● Firewall
What are the four basic characteristics of Network Architecture?
Fault Tolerance, Scalability, Quality of Service (QoS), Security
Connecting to the internet using a cellular phone with sim cards.
Cellular
It is the protection of the information or data transmitted over the network
Information Security
It prioritizes the bandwidth of live transmissions such as voice or live video which means other devices that are connected to the network will receive much lesser bandwidth causing it to be slow.
Quality of Service (QoS)
It allows users to use their own devices giving
them more opportunities and greater flexibility.
Bring your own device (BYOD)
It manages data as it flows through a network
Intermediary Devices
A network that lets one computer run both server
and client soft ware at the same time.
Peer-to-Peer Network
a network infrastructure that spans a small geographical area.
Local Area Network (LAN)
A type o f cloud Intended for a specific organization or
entity such as the government.
Private Cloud
It is the point where
two pieces of network equipment or protocol layers connect.
Interface or Network interface
Uses electrical impulses
Copper cable
A Computer hardware device that sends and
receives data packets over the network.
NIC (Network Interface Card)
diagrams illustrate the physical location of intermediary devices and cable installation
Physical Topology
Uses pulses of light.
Fiber-optic cable
It use symbols to represent devices within the network.
Network Diagram or Topology
Same as a Normal DSL but dedicated to more of a Business approach. It also uses various formats
such as Symmetric Digital Subscriber Line (SDSL).
Business DSL
What are the 3 goals in Network Security?
Confidentiality, Integrity, Availability
Provide a secure access network for individuals who work for different organizations that need access to their data on their network.
Extranet
What are the computers that send requests to the servers to retrieve information?
Client
A type o f cloud available to the general public through a pay-per-use model or for free.
Public Cloud
Keeping your network secure
Network Security
A high bandwidth internet connection that runs over a telephone line.
Digital Subscriber Line (DSL)
Just like in Home office connection it can also use ________ but only if wired solution is not available.
Satellite
It can allow devices to connect to a LAN where data network cables or wireless communications are not a viable option.
