Q

Implemented in the WPA2 standard, AES uses a different and more secure encryption algorithm, called CCMP. However, while it is possible to upgrade some legacy WEP equipment to support WPA‐TKIP, most equipment cannot be upgraded to support AES. As a result, a wireless network will probably not be able to use AES encryption unless the organization chooses equipment that specifically supports it.

Q

a collection of IP extensions that provide additional security for network communications. DirectAccess relies on IPsec to authenticate users and computers and to encrypt data exchanged by clients and servers.

A

IPsec

19
Q

L2TP relies on the IP security extensions (IPsec) for encryption, and as a result performs a double encapsulation.

A

Layer 2 Tunneling Protocol (L2TP)

20
Q

increases wireless networking speeds by using multiple transmitter and receiver antennae on each device

A

multiple‐input multiple‐output (MIMO)

21
Q

a form of fault tolerance that individual users can employ to maintain access to their server files, even in the event of a network service failure.

A

Offline Files

22
Q

takes the place of the Ethernet protocol at the data‐link layer, by encapsulating the datagrams created by the Internet Protocol (IP) at the network layer, to prepare them for their transmission.

A

Point‐to‐Point Protocol (PPP)

23
Q

The oldest and least secure of the VPN protocols, PPTP takes advantage of the authentication, compression, and encryption mechanisms of PPP, tunneling the PPP frame within a Generic Routing Encapsulation (GRE) header and encrypting it with Microsoft Point‐to‐Point Encryption (MPPE) using encryption keys generated during the authentication process.

A

Point‐to‐Point Tunneling Protocol (PPTP)

24
Q

the default selection for new connections and the strongest password‐based mechanism in Windows 7, requires a certificate only at the server.

A

Secure Password (EAP‐MSCHAPv2)

25
Q

Introduced in Windows Server 2008 and supported only by clients running Windows Vista SP1 or later, SSTP encapsulates PPP traffic using the Secure Sockets Layer (SSL) protocol supported by virtually all web servers.

A

Secure Socket Tunneling Protocol (SSTP)

26
Q

The sending system splits its data into two signals for transmission, and the receiving device reassembles the signals into a single data stream.

A

spatial multiplexing

27
Q

Implemented in the original WPA standard, TKIP encrypts data using the RC4 algorithm with a 128‐bit key. This is the same algorithm as WEP, but TKIP virtually eliminates WEP’s most exploited vulnerability by using a unique encryption key for each packet.

A

Temporal Key Integrity Protocol (TKIP)

28
Q

functionally similar to the BranchCache except that each Windows 7 workstation has exclusive use of its own cache; it does not share the cached files with other clients.

A

transparent caching

29
Q

a dedicated cryptographic processor chip that the system uses to store the BitLocker encryption keys.

A

Trusted Platform Module (TPM)

30
Q

VPN clients and servers use a specialized protocol when establishing a connection, which encapsulates their data packets inside another packet

A

tunneling

31
Q

the remote client and the remote access server are both connected to the Internet, using local service providers.

A

virtual private network (VPN)

32
Q

enables a computer to reconnect to a VPN server automatically, after an interruption as long as eight hours. VPN only works with connections that use the IKEv2 protocol, which means that the client must be running Windows 7 and the remote access server must be running Windows Server 2008 R2.

A

VPN Reconnect

33
Q

inherently more secure than WEP, so they are usually preferable, but if the network has any devices that do not support WPA, you must either replace those devices or settle for WEP.WPA can use the same authentication mechanisms and encryption algorithms as WEP, which enables manufacturers to add support for WPA to existing products with a simple software or firmware upgrade.

A

WiFi Protected Access (WPA and WPA2)

34
Q

a wireless security protocol that helps protect transmitted information by using a security setting, called a shared secret or a shared key, to encrypt network traffic before sending it.

A

Wired Equivalent Privacy (WEP)
