access log A log that can provide details regarding requests for specific files on a system.
audit log A log that is used to record which user performed an action and what that action was.
cloud computing A pay-per-use computing model in which customers pay only for the online computing resources that they need, and the resources can be easily scaled.
cloud storage A cloud system that has no computational capabilities but provides remote file storage.
community cloud A cloud that is open only to specific organizations that have common concerns.
disabling unused interfaces A security technique to turn off ports on a network device that are not required.
event log Log that documents any unsuccessful events and the most significant successful events.
Fibre Channel A high-speed storage network protocol that can transmit up to 16 gigabits per second.
Fibre Channel over Ethernet A high-speed storage network protocol that encapsulates Fibre Channel frames over Ethernet networks.
File Transfer Protocol (FTP) An unsecure TCP/IP protocol that is commonly used for transferring files.
flood guard A feature that controls a device's tolerance for unanswered service requests and helps to prevent a DoS or DDoS attack.
FTP Secure A TCP/IP protocol that uses Secure Sockets Layer or Transport Layer Security to encrypt commands sent over the control port (port 21) in an FTP session.
host availability The ability to quickly make new virtual serer machines available.
host elasticity The ability to easily expand or contract resources in a virtualized environment.
hybrid cloud A combination of public and private clouds.
IEEE 802.1x A standard that authenticates users on a per-switch port basis by permitting access to valid users but effectively disabling the port if authentication fails.
Infrastructure as a Service (laaS) A cloud computing model in which customers have the highest level of control and can deploy and run their own software.
Internet Control Message Protocol (ICMP) A TCP/IP protocol that is used by devices to communicate updates or error information to other devices.
Internet Protocol version 6 The next generation of the IP protocol that addresses weaknesses of IPv4 and provides several significant improvements.
IP telephony Using a data-based IP network to add digital voice clients and new voice applications onto the IP network.
iSCSI(Internet Small Computer System Interface) An IP-based storage networking standard for linking data storage facilities.
log A record of events that occur.
loop protection Technique to prevent broadcast storms by using the IEEE 802.1d standard spanning-tree algorithm (STA).
MAC limiting and filtering A security technique to limit the number of media access control (MAC) addresses allowed on a single port.
NetBIOS (Network Basic Input/Output System) An older transport protocol used by Microsoft Windows systems for allowing applications on separate computers to communicate over a LAN.
patch compatiblity The impact of a patch on other software or even hardware.
Platform as a Service (PaaS) A cloud service in which consumers can install and run their own specialized applications on the cloud computing network.
private cloud A cloud that is created and maintained on a private network.
public cloud A cloud in which the services and infrastructure are offered to all users with access provided remotely through the Internet.
rule-based management The process of administration that relies on following procedural and technical rules.
sandboxing Using a virtual machine to run a suspicious program to determine if it is malware.
Secure Copy Protocol (SCP) A TCP/IP protocol used mainly on UNIX and Linux devices that securely transports files by encrypting files and commands.
Secure FTP (SFTP) A secure TCP/IP protocol that is used for transporting files by encrypting and compressing all data and commands.
security control testing Testing the existing security configuration.
security log Log that can reveal the types of attacks that are being directed at the network and if any of the attacks were successful.
Simple Network Management Protocol (SNMP) A TCP/IP protocol that exchanges management information between networked devices. It allows network administrators to remotely monitor, manage, and configure devices on the network.
snapshot An instance of a particular state of a virtual machine that can be saved for later use.
Software as a Service (SaaS) A model of cloud computing in which the vendor provides access to the vendor's software applications running on a cloud infrastructure.
storage area network (SAN) A dedicated network storage facility that provides access to data storage over a high-speed network.
Telnet An older TCP/IP protocol and an application used for text-based communication.
Transmission Control Protocol/Internet Protocol (TCP/IP) The most common protocol suite used today for local area networks (LAN) and the Internet.
Trivial File Transfer Protocol (TFTP) A light version of FTP that uses small amount of memory and has limited functionality.
virtualization A means of managing and presenting computer resources by function without regard to their physical layout or location.
