Basic Structure Server(host) NFS1 Server TS7220 … … Entrance (client) Exit(client) TS7250 TS7250 … Security System based on Real-time Embedded System Guanlong Zhou
Basic principle Database Server NFS1 Server Host Server (Message Processor) Socket Client Server (I/O Simulator) TS7250 Client Security System based on Real-time Embedded System Guanlong Zhou
Commands(send from clients) Start the server. -To start the host service Close the server. -To close the host service In $StudentID. -Login command Out $StudentID. -Logout command Time of systam alive. -Check system life How many people are in the sys? Who are in the system? -Check who is still online TS7250 Security System based on Real-time Embedded System Guanlong Zhou
Feedback(receive from host) Pass In/Out $StudentID Deny $StudentID :$reason Server Closed/Start successfully/error. Server has been online for $time seconds. $number people are still online.

DOS: Denial-Of-Service attack In computing, a denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a machine or network resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of efforts to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet.
