LITERATURE SURVEY According to Authors RajniRanjan Singh and Deepak Singh Tomar, Department of Computer Science and Engineering, Maulana Azad National Institute of Technology, Bhopal, M.P., India., Port scanning is a process of probing networks, finding vulnerabilities and then infiltrate IT recourses. It is often the fundamental method utilized by intruder prior to initiate a targeted cyber-attack. Port scan attack traffic does not contain any specific signature, therefore IDS based detection may suffer by generating many/false alerts. Manual examination is an error prone, labor intensive and time consuming process. This work presented an approach to detect port scanning attack based on the entropy and failed connection attempt made by each host. To analyze and prioritize the observed evidence, DempsterShafer theory is utilized to calculate combined belief of each host in support of the proposed hypothesis. TCP port scanners are specialized programs used to determine what TCP ports of a host have processes listening on them for possible connections. Since these ports characterize, in part, the amount of exposure of the hosts to potential external attacks, knowing their existence is a fundamental matter for network and/or security administrators. Moreover, as scanners are also used by hackers, administrators need to know how they work and what possible weakness they exploit to be able to prevent unwanted scanning or at least to record each scanning attempt. WORKING METHODOLOGY The working of an open port scanner to identify open ports using Python involves establishing connections to specific ports on a target system to determine whether they are open, closed, or filtered. Here’s a step-by-step explanation of how such a scanner operates: Input Parameters: The user provides input parameters to the scanner, including the target IP address or hostname and a range of ports to scan. Additional options may include the choice of scanning technique (e.g., TCP, UDP), timeout values, and output preferences. Socket Creation: The Python program uses the socket library to create a socket, which is the endpoint for network communication. The scanner creates a socket for each port to be scanned. Port Loop: The scanner enters a loop to iterate over the specified range of ports. For each port in the range, the following steps are performed: Socket Connection Attempt: The scanner attempts to establish a connection to the target host’s IP address and the current port using the created socket. The specific method used (e.g., TCP connect, SYN, or UDP) depends on the scanning technique chosen. Handling Connection Result: Depending on the outcome of the connection attempt, the scanner records the status of the port: If the connection is successful, the port is marked as “open.” If the connection is refused, the port is marked as “closed.” If the connection times out or encounters an error, the port status may be marked as “filtered” or “unreachable.” The purpose", "lang": "en" }, "license": { "url": "https://creativecommons.org/licenses/by/4.0/", "start": "2023-12-12", "applies_to": "vor" }, "references": [ { "key": "ref1", "unstructured": "Fyodor, “The Art of Port Scanning”, Phrack Magazine, Volume 7, Issue 51, September 01 1997, Article 11 of 17" }, { "key": "ref2", "unstructured": "Shaun Jamieson, “The Ethics and Legality of Port Scanning”, October8,2001.http://www. sans.org/reading-room/whitepapers/legal/71. php" }, { "key": "ref3", "doi": "10.1109/wetice.2005.51", "unstructured": "Kocher, J.E.; Gilliam, D.P., “Self port scanning tool: providing a more secure computing environment through the use of proactive port scanning”, 14th IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprise, 13-15 June 2005" }, { "key": "ref4", "unstructured": "Roger Christopher, “Port Scanning Techniques and the Defense Against Them”, October 5, 2001. http://www.sans.org/reading-room/ whitepapers/ auditing/70.php" }, { "key": "ref5", "unstructured": "Kimberly Graves, “Official Certified Ethical Hacker Review Guide”, Wiley Publishing, pp.15- 65, February 2007" }, { "key": "ref6", "unstructured": "Fyodor, “Remote OS Detection using TCP/ IP Fingerprinting(2ndGeneration)”,Jan2007. http://nmap.org/osdetect/index. html#id287961.
