被掃PORT

請問大大我在防火牆上有看到此筆紀錄
SCS: SSH client at 10.1.1.163 has attempted to make an SCS connection to interface untrust with IP 190.81.35.90 but failed because SCS is not enabled for that interface.
請問是否有很嚴重的狀況

也看到被掃PORT的紀錄
Port Scan Attempt, From 220.130.117.39/80 to 10.1.1.163/1076, using protocol TCP (on zone Untrust,interface untrust) occurred 1 times
請問要如何處理

請問以下的紀錄是怎麼樣的情況導致而成的
還請大大看一下
Session utilization has reached 1843, which is 90% of the system capacity!
