Which of the following network scanning tools is a TCP/UDP port scanner that works as a ping sweeper and hostname resolver?
Correct Answer: B
SuperScan is a TCP/UDP port scanner. It also works as a ping sweeper and hostname resolver. It
can ping a given range of IP addresses and resolve the host name of the remote system.
The features of SuperScan are as follows:
It scans any port range from a built-in list or any given range.
It performs ping scans and port scans using any IP range.
It modifies the port list and port descriptions using the built in editor.
It connects to any discovered open port using user-specified "helper" applications.
It has the transmission speed control utility.
Answer option D is incorrect. Nmap is a free open-source utility for network exploration and security auditing. It is used to discover computers and services on a computer network, thus creating a "map" of the network. Just like many simple port scanners, Nmap is capable of discovering passive services. In addition, Nmap may be able to determine various details about the remote computers. These include operating system, device type, uptime, software product used to run a service, exact version number of that product, presence of some firewall techniques and, on a local area network, even vendor of the remote network card. Nmap runs on Linux, Microsoft Windows, etc. Answer option C is incorrect. Netstat (network statistics) is a command-line tool that displays network connections (both incoming and outgoing), routing tables, and a number of network interface statistics. It is available on Unix, Unix-like, and Windows NT-based operating systems. It is used to find problems on the network and to determine the amount of traffic on the network as a performance measurement. Answer option A is incorrect. Hping is a free packet generator and analyzer for the TCP/IP protocol. Hping is one of the de facto tools for security auditing and testing of firewalls and networks. The new version of hping, hping3, is scriptable using the Tcl language and implements an engine for string based, human readable description of TCP/IP packets, so that the programmer can write scripts related to low level TCP/IP packet manipulation and analysis in very short time. Like most tools used in computer security, hping is useful to both system administrators and crackers (or script kiddies).
