ntoskrnl.exe permitted/authorized [hard-coded]

[Phant0m]

Hey

I remember you, Frederic stating ntoskrnl.exe is permitted/authorized (allowing all traffic In-&-Out) by default by Look ‘n’ Stop Application Filtering layer, in-fact it is hard-coded and doesn’t get logged and no custom controls…

Will this always be the case? :-\

Hi Phant0m,

No, ntoskrnl.exe is not allowed by default. I think you are refering to "kernel32" which is allowed by default, but this is supposed to apply to Win9x/Me only. I don't remember exactly the purpose of that :-\

Not talking about "kernel32.dll" or "kernel32.exe" (which is a virus) I remember an internal windows process having simply "kernel32" as a name.

May I ask why are you asking that, Phant0m ?

What protocols is denied from ntoskrnl.exe?

[Frederic]

Sorry I don't understand you question since I just said "ntoskrnl.exe" is not blocked by default.
I don't know if this application is supposed to connect, and if it does, the protocols it will use.

Any update regarding this topic? :'(

As far as i know this is a process used in the boot up cycle standing in the background and not using the network.
Should not appear in WinTask unless altered by a virus such as w32.bolzano and variants.
A corrupt boot.ini file or missing boot.ini file would give a message related to this process and prevent booting.

But i'm also wondering where your question leads to

Also some software firewalls, it sees and offers controls unlike Look ‘n’ Stop currenty, see image attachment…

As for my question, it is a very appropriate question to ask on the support forum for a firewall product, MickeyTheMan…

I should have answered: there is no default handling (allowing or blocking) for ntoskrnl.exe.
But anyway I didn't understand your point.

Now with your last post I understand ntoskrnl.exe is supposed to connect.
I don't know the reason why Look 'n' Stop doesn't detect it.

No problem Fred, you very busy, understandable.
I appreciate the response, thanks, it clears up a lot.
Hope to see you address this in the near future, thanks.
