INTRODUCTION II. PORT SCANNING TOOLS Port scanning is one of the most important step in gathering A. NMAP: This tool developed by Fyodor is one of the the information(reconnaissance phase) about the victim best unix and windows based port scanners also used as against whom you want to launch attack or simply command-line program. The advanced port scanner tool gathering loop holes of your own system to prevent from has a number of useful aspects that gives user a lot of hackers. This technique composed of sending a message to control over the process. Nmap “NETWORK MAPPER” is a port and listening for an answer. Port scanning is done to capable of doing many types of scans and OS identification get the current state of the port means weather Port is open, it also has the ability to blind scan and zombie scan, and it close, filtered or prevented. Port Scan is the act of enables to control the speed of the scan from slow to very systematically scanning a computer's ports [1,2]. Since a fast. It can be used for security scans, simply to identify port is a spot where information goes into and out of a which services a host is running, to "fingerprint" the computer, port scanning identifies open doors/ports to a operating system and applications on a host and the type of computer system. Port scanning is basically like ringing a firewall a host is using, or to do a quick inventory of a local door bell of someone’s home, if somebody responds to network [4]. It is, in short, a very good tool to know. Nmap ringing door bell it results in existence of someone at home. can be used for discovering, monitoring, and If no one respond then there will be two situations, First troubleshooting.TCP and UDP based systems.

  • Know Your Network
    Know Your Network Network Security Assessment Chris McNab CHAPTERChapter 4 4 IP Network Scanning This chapter focuses on the technical execution of IP network scanning. After under- taking initial reconnaissance to identify IP address spaces of interest, network scan- ning builds a clearer picture of accessible hosts and their network services. Network scanning and reconnaissance is the real data gathering exercise of an Internet-based security assessment. The rationale behind IP network scanning is to gain insight into the following elements of a given network: • ICMP message types that generate responses from target hosts • Accessible TCP and UDP network services running on the target hosts • Operating platforms of target hosts and their configuration • Areas of vulnerability within target host IP stack implementations (including sequence number predictability for TCP spoofing and session hijacking) • Configuration of filtering and security systems (including firewalls, border rout- ers, switches, and IDS sensors) Performing both network scanning and reconnaissance tasks paints a clear picture of the network topology and its security mechanisms. Before penetrating the target net- work, further assessment steps involve gathering specific information about the TCP and UDP network services that are running, including their versions and enabled options. ICMP Probing The Internet Control Message Protocol (ICMP) identifies potentially weak and poorly protected networks. ICMP is a short messaging protocol that’s used by sys- tems administrators and end users for continuity testing of networks (e.g., using the ping or traceroute commands). From a network scanning and probing perspective, the following types of ICMP messages are useful: 36 This is the Title of the Book, eMatter Edition Copyright © 2004 O’Reilly & Associates, Inc.

An attacker performs port scans of IP addresses to find vulnerable hosts to compromise. However, it is also useful for system administrators and other network defenders to detect port scans as possible preliminaries to more serious attacks. It is a very difficult task to recognize instances of malicious port scanning. In general, a port scan may be an instance of a scan by attackers or an instance of a scan by network defenders. In this survey, we present research and development trends in this area. Our presentation includes a discussion of common port scan attacks. We provide a comparison of port scan methods based on type, mode of detection, mechanism used for detection, and other characteristics. This survey also reports on the available datasets and evaluation criteria for port scan detection approaches.

Department of Computer Science & Applications, K.M.V., Jalandhar, Punjab, India 3 Abstract: Scanning is a skilled of pinpointing active and communicable system via internet. It makes use of assorted approaches such as operating system identification and port scanning to be aware of various services which are solicited by the system. It offers us information concerning the TCP/UDP services which are active on each discovered system, architecture of the system, type of operating system etc. Today, there is a constant increase in the number of automated scanners which further provides a path for the successful set up of attacks. A part scanner is a piece of software framed to rummage a network for open ports. This is commonly used by administrators to keep an eye on the security of their networks and by hackers to compromise it. Programs make use of ports to see and acknowledge the out of doors world. Viruses now have inbuilt port scanners that rummage the internet searching for unsuspecting computers with open ports, when they discover them, they cripple our software or worse, stay hidden and report our secret activity and subject matter to another system. In this paper, we have studied the detailing of ports, relative services running on particular ports and also extend the critical subject matter concerning port scanning tools.

Information gathering, also known as foot- printing, is the process of gathering all available information about an organization. In the age of the Internet, information is available in bits and pieces from many different sources. Seemingly insignificant bits of information can be enlightening when pieced together—which is the purpose of information gathering. Footprinting can be effective in identifying high- value targets, which is what hackers will be looking for to focus their efforts. A hacker uses information-gathering techniques to determine organizations’ high-value targets, where the most valuable information resides. Not only does information gathering help identify where the information is located, but it also helps determine the best way to gain access to the targets. This information can then be used to identify and eventually hack target systems. Many people jump right into running hacking tools, but information gather- ing is critical in minimizing the chance of detection and assessing where to spend the most time and effort.

Enumeration is the follow-on step once scanning is complete and is used to identify computer names, usernames, and shares. Scanning and enumeration are discussed together in this chapter because many hacking tools perform both steps simultaneously. Scanning After the reconnaissance and information-gathering stages have been completed, scanning is performed. It is important that the information-gathering stage be as complete as possi- ble to identify the best location and targets to scan. During scanning, the hacker continues to gather information regarding the network and its individual host systems. Information such as IP addresses, operating system, services, and installed applications can help the hacker determine which type of exploit to use in hacking a system. Scanning is the process of locating systems that are alive and responding on the network.
