 It just says IP

 It just says IP 193.192.116.240 tried to Attack/infect your computer.But it has been blocked by SEP.
ntoskrnl.exe is used for File and Print sharing.

 However if you want to

 However if you want to exclude it then. Which IMO is not a good option.

In SEPM goto "Clients" and click on any of your groups. Then open the "Policies" tab. Click on the third option "Network Application Monitoring". You can switch it off or add an execption for NTOSKRNL.EXE.

If the computer is connected

Solution

If the computer is connected directly to the internet..Hackers will try their chances and you can't help it.The best thing is it is getting blocked.
As these IP's have been flagged you can forward it to your Network Admin and he can block it on the Hardware Firewall .

On BackTracing 193.192.116.240 it says it is coming from Istanbul.So just check if it from your network or its just an outsider..
however this is coming from a long way from CHINA 218.23.37.51
On my home PC i've got a static IP and I see attacks from IPs that come from all across the world.

Oh i see. we cannot blocked

Oh i see. we cannot blocked it because if we blocked 218.23.37.51 hacker try with another ip address 218.23.37.250 etc.
Thanks for answer Vikram.
Have a nice day.
