Why am I deleting these files


Recommended Posts

Posted

Hello,

I was told that the security regulations at my organization require me

to delete the following files. I was curious if anyone could tell me

why and possible consequences. Thanks for any help.

 

Delete:

ir : c:\winnt\inf

c:\winnt\inf\system32\drivers

c:\winnt\inf\system32\drivers\dllcache

 

netir : all directories

nscirda : all directories

Posix: all directories

os2 .exe: all directories

.ex_ : all directories

Most likely an over-anxious security person. Even DISA (used to

secure Gov't computer systems) doesn't require you to delete all of

those files. POSIX and OS2, yes... but not the rest, especially the

dllcache directory!

 

Most security folks are of the mindset to eliminate any possibility of

compromise. For example, I can take an ex_ file and expand it to

allow me to use the exe that is being blocked by security settings

elsewhere. This may be stopped by setting the security the same, but

most security folks don't think that's enough of a prevention method.

Protection in multiple layers, in case one layer is compromised there

is another.

Kind of funny though style_emoticons/

 

He is correct - those directories are being deleted due to the high

probability of being attacked by viruses/malware. The filenames

are being deleted because they can either be manipulated or exploited. This

seems a little paranoid..

 

Shouldn't actually hurt anything, though.

You're only paranoid if the whole world ISN'T out to get you <grin>

 

Shouldn't hurt if you secure the directories from all but system and

admin (read: remove EVERYONE group) as these are your "trusted" folks.

Also helps if you are behind (multiple) firewall(s)
