Method of using Raspberry Pi as safe front end processor of high-performance computing cluster

Abstract

The invention discloses a method of using Raspberry Pi as a safe front end processor of high-performance computing cluster, and belongs to the field of computer security technology. The method of using Raspberry Pi as the safe front end processor of the high-performance computing cluster includes the following steps: S1: burning an operating system of Raspberry Pi and setting a public network IP of the operating system; S2: setting a complex password for the operating system of Raspberry Pi and prohibiting a root user to login directly; S3: modifying a ssh default port number, restricting an IP address access, and enabling a permitted IP or IP address block to login Raspberry Pi equipment; and S4: prohibiting external ping by a server. The method of using Raspberry Pi as the safe front end processor of the high-performance computing cluster has the advantages of increasing a security factor of the front end processor of the high-performance computing cluster, and guaranteeing the high-performance computing cluster safely running calculation tasks, with good value of popularization and application.

Description

technical field [0001] The invention relates to the technical field of computer security, and specifically provides a method for using a raspberry pie as a security front-end processor of a high-performance computing cluster. Background technique [0002] The Raspberry Pi is developed by the "Raspberry Pi Foundation", a charitable organization registered in the UK, with Eben Upton / E Upton as the project leader. In March 2012, Eben Epton (Eben Epton, Cambridge University) officially launched the world's smallest desktop computer, also known as a card computer, which is only the size of a credit card but has all the basic functions of a computer. This is the Raspberry Pi Computer board, the Chinese translation is "Raspberry Pi". The foundation's mission is to improve education in computer science and related subjects in schools, and to make computers fun. The Foundation expects that more applications of this computer will be continuously developed and applied to more fields,...

Problems solved by technology

However, under the existing technology, there are also serious security risks in the front-end computer. Once the front-end computer system is hacked, the risk of the back-end high-performance computing cluster will be completely exposed.
