Safety accessing system and safety accessing method for character terminal RLOGIN protocol

Abstract

The invention belongs to the technical field of computer network security, and discloses a safety accessing system and a safety accessing method for a character terminal RLOGIN protocol. The safety accessing system for the character terminal RLOGIN protocol comprises an SSH (secure shell) agency service terminal and a character login access control service terminal, wherein the SSH agency service terminal is used for SSH connection from client sides to login an internal network, verifying identifications and selecting equipment requiring to be accessed, and the character login access control service terminal is used for connecting an RLOGIN protocol to a selected UNIX / LINUX server, converting data between encrypted data and unencrypted data, simultaneously monitoring keywords of an instruction, and performing instruction blocking as required. On the basis of not changing existing network environment and operation habits as far as possible, the safety accessing system and the safety accessing method for the character terminal RLOGIN protocol guarantees safety of access links, and can effectively manage network equipment and servers requiring to be accessed.

Description

technical field [0001] The invention belongs to the technical field of computer network security, in particular to a character terminal RLOGIN protocol security access system and method. Background technique [0002] RLOGIN is an old network protocol, but it is still used by web servers. Although it is convenient to use, it is also an insecure remote access protocol (non-encrypted). According to the applicant's understanding, the RLOGIN protocol is not used very much now, but in some occasions, it will bring great convenience, so in the process of network maintenance, many people will still use it, especially for some Old equipment is more convenient to use. For RLOGIN is an insecure remote access protocol (non-encrypted), the more effective solution is to completely replace it with the SSH login protocol, but for early versions of network operating systems such as AIX UNIX, SCO UNIX and other UNXI systems, SSH The service needs to be installed and configured separately, w...

AI Technical Summary

Problems solved by technology

For RLOGIN is an insecure remote access protocol (non-encrypted), the more effective solution is to completely replace it with the SSH login protocol, but for early versions of network operating systems such as AIX UNIX, SCO UNIX and other UNXI systems, SSH The service needs to be installed and configured separately, which will increase the work pressure on the management personnel. If it is a machine in a production environment, it will also bear the risk of installation failure.

It can be seen that it is not easy to completely replace the remote login of RLOGIN with SSH in the current network environment.
