The OSI Reference Model is a theoretical model of networking with interchangeable layers.
The Transport Layer of the OSI Reference Model creates, maintains, and disconnects communications that take place between processes over the network.
The Physical Layer of the OSI Reference Model must translate the binary ones and zeros of computer language into the language of the transport medium.
IP addresses are eight-byte addresses that uniquely identify every device on the network.
A packet-filtering firewall remembers information about the status of a network communication.
A network protocol governs how networking equipment interacts to deliver data across the network.
Another name for a border firewall is a DMZ firewall.
Internet Control Message Protocol (ICMP) is a method of IP address assignment that uses an alternate, public IP address to hide a system's real IP address.
Network access control (NAC) works on wired and wireless networks.
The term "router" describes a device that connects two or more networks and selectively interchanges packets of data between them.
The Data Link Layer of the OSI Reference Model is responsible for transmitting information on computers connected to the same local area network (LAN).
A border router can provide enhanced features to internal networks and help keep subnet traffic separate.
Internet Small Computer System Interface (iSCSI) is a storage networking standard used to link data storage devices to networks using IP for its transport layer.
TCP/IP is a suite of protocols that operates at both the Network and Transport layers of the OSI Reference Model.
A subnet mask is a partition of a network based on IP addresses.
The three main categories of network security risk are reconnaissance, eavesdropping, and denial of service.
A firewall is a basic network security defense tool.
Implicit deny is when firewalls look at message addresses to determine whether a message is being sent around an unending loop.
