The Design of Large Scale IP Address and Port Scanning Tool

Abstract

The control network is an important supporting environment for the control system of the heavy ion accelerator in Lanzhou (HIRFL). It is of great importance to maintain the accelerator system’s network security for the stable operation of the accelerator. With the rapid expansion of the network scale and the increasing complexity of accelerator system equipment, the security situation of the control network is becoming increasingly severe. Port scanning detection can effectively reduce the losses caused by viruses and Trojan horses. This article uses Go Concurrency Patterns, combined with transmission control protocol (TCP) full connection scanning and GIMP Toolkit (GTK) graphic display technology, to develop a tool called HIRFL Scanner. It can scan IP addresses in any range with any ports. This is a very fast, installation-free, cross-platform IP address and port scanning tool. Finally, a series of experiments show that the tool developed in this paper is much faster than the same type of software, and meets the expected development needs.

Security System Analysis Using the HTTP Protocol Against Packet Sniffing Attacks

“…The Ettercap application provides various scanning methods that can be used to group multiple target IP addresses for scanning. However, the downside is that the scan results for hosts cannot be provided until the entire batch scanning process is completed [24].…”

Implementation of Deep Neural Network in the Design of Ethereum Blockchain Scam Token Detection Applications

“…Sistem deteksi scam token pada jaringan blockchain Ethereum dirancang menggunakan Bahasa pemrograman Golang yang dapat di implementasikan dengan program milik Ethereum Geth (goethereum), Bahasa Golang digunakan karena dapat membaca inputan angka yang sangat besar dan hasilnya cukup akurat, juga merupakan bahasa pemrograman sumber terbuka yang memudahkan pembuatan perangkat lunak yang sederhana, andal, dan efisien [12].…”

A Trusted Platform Module-based, Pre-emptive and Dynamic Asset Discovery Tool

“…A tool similar to Nmap, but making use of the powerful concurrent capabilities of the Golang programming language is presented in [13]. While this tool, given its concurrent nature, is faster than the original Nmap, it still have the limitation of not being able to scan networks with private IP addresses.…”
