Abstract
Computer systems and applications on the internet provide services to outsiders and, at the same time, the vulnerabilities may be exploited by attackers and leak some sensitive private information. To collect and monitor the service information provided by the network environment such as IoT (Internet of Things), vehicular networks, cloud computing, and cloud storage, it is particularly important that a system can provide faster service discovery for discovering and identifying specific network services. The current service discovery systems mainly use port scanning technology, including Nmap, Zmap, and Masscan. However, these technologies hard code the service features and only support common services so that cannot cope with real-time updates and changing network services. To solve the above problems, this paper proposed a customizable distributed network service discovery system based on stateless scanning technology of Masscan and proposed a customizable interactive pattern set syntax. The system used random destination address technologies to scan for Ipv4 address allocation and used a distributed deployment scheme. Experimental results show that the system has high scanning speed and has high adaptability to new services and special services.

Summary
With the growth of internet devices and applications, various large scale cyberattacks continue to emerge, and internet vulnerabilities show a surging trend [1, 2]. Despite the recent growth in computer networking best practices, the continual improvement in Internet-based services has presented new challenges in maintaining security and preserving privacy [3, 4]. In one hand, supported services are mostly hard coded in the system, and for less common, newer services, you need to wait for the developer’s update support. It has poor scalability, as evidenced by the famous Masscan, which only supports HTTP, SSL, and other common protocols but ignores industrial network protocols and instant messaging protocols. In order to solve the above problems, we designed a customizable distributed network service discovery system (CDNSDS) in this paper.
