Networks
A network contained within a small geographic area, usually within the same building
What is a Local Area Network (LAN)?
a protocol for physical network connections that requires the use of cables called by the same name.
What is Ethernet?
Layer 1
What is the Physical Layer?
Layer 6
What is the Presentation Layer?
technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.
What is Data Loss Prevention (DLP)?
A way of splitting up traffic on the same physical network into two or more networks.
What is a Virtual LANs, or VLANs?
A wireless protocol for connecting to a network via radio waves.
What is WiFi?
Layer 2
What is the Data Link Layer?
Layer 7
What is the Application Layer?
Products, including physical and virtual appliances and server software, that pull together the information that your security staff needs to identify and respond to threats.
What is a Security information and event management tool?
A large computer network that connects groups of computers over large distances.
What is a wide area network (WAN)?
The protocol that allows communication between a server and browser.
What is Hyper-Text Transfer Protocol (HTTP)?
Layer 3
What is the Network layer?
This layer defines how to start, control, and end conversations.
What is OSI Model Layer 5, Session Layer?
A network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules
What is a Firewall?
This device connects devices within a network (often a local area network, or LAN) and forwards data packets to and from those devices.
What is a switch?
A reliable, connection-oriented protocol that helps in the sequential transmission of data packets to ensure data reaches the destination on time without duplication.
What is Transmission Control Protocol (TCP)?
Layer 4
What is the Transport Layer?
This layer defines the rules that determine when a device can send data over a particular medium.
What is Layer 2, Data Link layer?
A security tool or service that helps an organization identify malicious traffic and proactively blocks it from entering their network.
What is an intrusion prevention system (IPS)?
This mechanism encrypts the connection from an endpoint to a network, often over the internet.
What is tunneling (or VPN)?
Allows file sharing between servers by establishing two TCP connections, one for data transfer and the other for control.
What is File Transfer Protocol (FTP)?
Layer 5
What is the Session Layer?
This layer provides an interface between the communications software and any applications that need to communicate outside the computer on which the application resides.
What is Layer 7, Application Layer?
A virtual point where network connections start and end.
What is a port?
