Network attack and Countermeasures Based on telnet connection in the era of Internet of Things

Internet of Things technology has profoundly changed people’s way of production, life and learning. When everything connected, the security of Internet of Things is becoming increasingly prominent, which has become one of the important factors to ensure the stability of regional economy. This paper gives the basic way of network attack based on telnet connection, introduces the basic principle of telnet protocol, analyzes three methods of obtaining telnet remote connection authority, and gives the feasible countermeasures to prevent network attack based on telnet connection.
