Subject: Whitelisting with IMA
Date: Sun, 12 May 2019 09:37:47 +0000	[thread overview]
Message-ID: <CAL8qiskDtYJ0NY3u+zV3YBMR4Qs_YcHSHZ61per5jwZ3n54r8A@mail.gmail.com> (raw)

tldr: Is there some way to ask IMA not to open (execute) unknown binaries

Hi all,

I saw some comments on RFC for WhiteEgret LSM. Someone on the same
thread said that IMA could be used for whitelisting as well. Based on
a couple of hours with IMA, it seems to me that IMA can only stop
execution of (altered) binaries whose hash/sign was earlier measured.

If a user installs a new (unknown) application, it seems like IMA is
going to allow that application to run since IMA can't find any
integrity loss since IMA doesn't have any 'good' value against the new
application. Is this correct? Or is there some other option to ask IMA
not to execute any unknown binary?

Kind regards,
m3hm00d
