A protection system and method for a virtual port

Abstract

The invention discloses a virtual port protection system and method. The protection system comprises a scanning unit, a protection conversion unit, a verification unit, a replacement unit and an execution unit, wherein the scanning unit transmits obtained information to the protection conversion unit for protection conversion, the verification unit verifies and marks a conversion result and sendsthe conversion result to the replacement unit, the replacement unit further processes the content, and the execution unit closes or restarts the system. The protection method comprises the steps: 1, port scanning; 2, port conversion; 3, new port verification. According to the method, through the protection transformation of the virtual port of the equipment host, an originally open port is hidden,an originally unopen port is used as a false open port to confuse attackers, and through port mapping, it is ensured that corresponding services can still be accessed through the original port, so the purpose of unmanned and full-time protection of equipment host security is achieved.

Description

technical field [0001] The invention relates to the field of network security, in particular to a virtual port protection system and method. Background technique [0002] With the development of science and technology, computers are being used more and more in various fields. Currently, computer virtual ports, as the communication portal at the software level, play an extremely important role, and therefore become the portal for many cybercriminals to carry out network attacks. . A service-providing device can provide multiple services at the same time, so it will also open multiple virtual ports for the corresponding services. In a network attack event, if an attacker wants to invade a certain host, he must know how many virtual ports the host has opened and what kind of virtual ports they are. At this time, the attacker often scans the target host with a scanner to determine which virtual ports are open. From the open virtual ports, the intruder can know roughly what ser...

Problems solved by technology

The above technical solution adopts the method of port hopping, although to a certain extent, it affects the effect of the attacker scanning the port, but because the server and the client are synchronously hopping, it is necessary to distribute the authentication information and initial Parameters or keys, so there is still information leakage, resulting in port hopping that cannot achieve the defense effect, and this kind of port hopping increases the network burden and affects communication efficiency
