GIAC GSNA Dumps Questions Answers

Ekahau is an easy-to-use powerful and comprehensive tool for network site surveys and optimization. It is an auditing tool that can be used to pinpoint the actual physical location of wireless devices in the network. This tool can be used to make a map of the office and then perform the survey of the office. In the process, if one finds an unknown node, ekahau can be used to locate that node. Answer: D is incorrect. AirSnort is a Linux-based WLAN WEP cracking tool that recovers encryption keys. AirSnort operates by passively monitoring transmissions. It uses Ciphertext Only Attack and captures approximately 5 to 10 million packets to decrypt the WEP keys. Answer: C is incorrect. Kismet is a Linux-based 802.11 wireless network sniffer and intrusion detection system. It can work with any wireless card that supports raw monitoring (rfmon) mode. Kismet can sniff 802.11b, 802.11a, 802.11g, and 802.11n traffic. Kismet can be used for the following tasks: To identify networks by passively collecting packets To detect standard named networks To detect masked networks

To collect the presence of non-beaconing networks via data traffic Answer: A is incorrect. KisMAC is a wireless network discovery tool for Mac OS X. It has a wide range of features, similar to those of Kismet, its Linux/BSD namesake and far exceeding those of NetStumbler, its closest equivalent on Windows. The program is geared toward network security professionals, and is not as novice-friendly as similar applications. KisMAC will scan for networks passively on supported cards - including Apple's AirPort, and AirPort Extreme, and many third-party cards, and actively on any card supported by Mac OS X itself. Cracking of WEP and WPA keys, both by brute force, and exploiting flaws such as weak scheduling and badly generated keys is supported when a card capable of monitor mode is used, and packet reinjection can be done with a supported card. GPS mapping can be performed when an NMEA compatible GPS receiver is attached. Data can also be saved in pcap format and loaded into programs such as Wireshark.

Data aggregation is any process in which information is gathered and expressed in a summary form, for purposes such as statistical analysis. A common aggregation purpose is to get more information about particular groups based on specific variables such as age, profession, or income. The information about such groups can then be used for Web site personalization to choose content and advertising likely to appeal to an individual belonging to one or more groups for which data has been collected. For example, a site that sells music CDs might advertise certain CDs based on the age of the user and the data aggregate for their age group. Online analytic processing (OLAP) is a simple type of data aggregation in which the marketer uses an online reporting mechanism to process the information. Answer: B is incorrect. Data aggregation can be user-based. Personal data aggregation services offer the user a single point for collection of their personal information from other Web sites. The customer uses a single master personal identification number (PIN) to give them access to their various accounts (such as those for financial institutions, airlines, book and music clubs, and so on). Performing this type of data aggregation is sometimes referred to as "screen scraping."

Hypertext Transfer Protocol (HTTP) is a client/server TCP/IP protocol used on the World Wide Web (WWW) to display Hypertext Markup Language (HTML) pages. HTTP defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. For example, when a client application or browser sends a request to the server using HTTP commands, the server responds with a message containing the protocol version, success or failure code, server information, and body content, depending on the request. HTTP uses TCP port 80 as the default port. Answer: B is incorrect. Port 443 is the default port for Hypertext Transfer Protocol Secure (HTTPS) and Secure Socket Layer (SSL). Answer: A, D are incorrect. By default, FTP server uses TCP port 20 for data transfer and TCP port 21 for session control.
