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.
