|
Definition
| First introduced in Vista and is in 7 Ultimate and 7 Enterprise, is a feature that makes it possible to encrypt an entire volume |
|
|
Term
| Data recovery agent (DRA) |
|
Definition
| Is a user account that an admin has authorized to recover BitLocker drives for an entire organization with a digital certificate on a smart card. |
|
|
Term
|
Definition
| Is a VPN-like technology that provides intranet connectivity to client computers when they are connected to the Internet. |
|
|
Term
|
Definition
| Standards that are published by the IEEE. They dictate the frequencies, transmission speeds, and ranges of wireless networking products. |
|
|
Term
| IKEv2 Mobility and Multihoming (MOBIKE) |
|
Definition
| Allows a mobile node encrypting traffic through IKEv2 to change point of attachment while maintaining a Virtual Private Network (VPN) session. |
|
|
Term
| Institute of Electrical and Electronic Engineers (IEEE) |
|
Definition
| An organization that continually develops standards for the networking and communications industry. |
|
|
Term
| Internet Key Exchange, Version 2 (IKEv2) |
|
Definition
| An authentication protocol that identifies the identity of both the client and server to each other. Once the identity of both sides is established, one or more IPSec based SAs are established between them for data transfer. Is considered a strong authentication protocol. |
|
|
Term
|
Definition
| Is a collection of IP extensions that provide additional security for networks communications. DirectAccess relies on it to authenticate users and computers and to encrypt data exchanged by clients and servers. |
|
|
Term
| Layer 2 Tunneling Protocol (L2TP) |
|
Definition
| Is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself; it relies on an encryption protocol that it passes within the tunnel to provide privacy. |
|
|
Term
| Multiple-input multiple-output (MIMO) |
|
Definition
| A design in newer routers that provides for faster wireless data transmission by utilizing more than one antenna to transmit and receive data. |
|
|
Term
|
Definition
| Is a form of fault tolerance that individuals users can employ to maintain access to their server files, even in the event of a network service failure. |
|
|
Term
| Point-to-Point Protocol (PPP) |
|
Definition
| Is a connection between the clients and the server, during which the server authenticates the client and the computer negotiate a set of communication parameters they have in common. |
|
|
Term
| Point-to-Point Tunneling Protocol (PPTP) |
|
Definition
| Enables the secure transfer of data from a remote computer to a private server by creating a VPN connection across IP-based data networks. |
|
|
Term
| Secure Password (EAP-MSCHAPv2) |
|
Definition
| One of three types of EAP-based authentication supported by Windows 7, the default selection for new connections, and the strongest password-based mechanism in Windows 7. |
|
|
Term
| Secure Socket Tunneling Protocol (SSTP) |
|
Definition
A protocol that allows secure communication between a VPN client
and server using the SSL based encryption methods of HTTPS. The connection between client and server is not likely to be stopped by a fi rewall because the HTTPS protocol is not commonly blocked. |
|
|
Term
|
Definition
| Sending system splitting data into two signals for transmission, and the receiving device reassembles the signals into a single data stream |
|
|
Term
| Temporal Key Integrity Protocol (TKIP) |
|
Definition
| Encrypts data using the RC4 algorithm with a 128-bit key. It has the same algorithm as WEP but eliminates WEP's most exploited vulnerability by using a unique encryption key for each packet. |
|
|
Term
|
Definition
| Is functionally similar to the BranchCache feature, except that each Windows 7 workstation has exclusive use of its own cache; it does not share the cached files with other clients. |
|
|
Term
| Trusted Platform Module (TPM) |
|
Definition
| Is a special microchip, installed on a motherboard, that stores passwords, keys, and digital certificates. Various services, such as BitLocker can store such security data in this chip. (16) |
|
|
Term
|
Definition
| The process by which VPNs transfer information by encapsulating traffic in IP packets over the Internet. |
|
|
Term
| Virtual private network (VPN) |
|
Definition
| The client established a connection to the server using the Internet as a network medium and, after authentication, the server grants the client access to the network. |
|
|
Term
|
Definition
| Enables a remote computer to automatically re-establish a connection to a VPN server running Windows Server 2008 R2. |
|
|
Term
| Wifi Protected Access (WPA and WPA2) |
|
Definition
| Is a security standard to secure computers connected to a Wi-Fi network. Its purpose is to achieve complete compliance with the IEEE802.11i standard. Will not work with some older network cards, thus the need for concurrent security standards. |
|
|
Term
| Wired Equivalent Privacy (WEP) |
|
Definition
| The oldest of the Wi-Fi encryption standards. It uses 64- or 128-bit encryption that is easily broken. It does not encrypt the actual data in a packet, and it does not perform user authentication on a packet. (16) |
