Hi Team,
We have requirement where we have to monitor and log any read operations performed on a
file.
e.g. /a/b/c/xyz.log
This file is usually copied and downloaded by many users using various operations, like,
wget, ssh, jsp Download link provided. These commands are fired from different hosts.
With the auditd we want to create a rule which auditctl can leverage to log the User ID
that is reading (and copying) it from a different host may be. I have gone through many of
the rules but didn't find anything fruitful as such (which logs wget, scp commands
from remote hosts). May be I am missing on something. Since it is a very crucial
requirement, appreciate your guidance and directions with this.
Let me know in case you require any further information from my end. Many thanks in
advance.
Thanks and Regards,Varun Gulati

You will get the local auid/uid that the kernel sees when the request triggers
the rule. There is nothing more that can be done from the audit system.

Hi Steve,
Thanks for your suggestions. We incorporated the below rule for auditctl which you
suggested, but unfortunately it didn't helped. We are able to log the wget from the
same server but unfortunately it is still not logging from a different host:
-a always,exit -F path=/a/b/c/xyz.log -F perm=r -F key=log-access
This is how the file looks like:
-w /a/b/c/xyz.log -p rwxa -k Audit
-w /usr/bin/wget -p rwxa -k Audit
-a always,exit -F path=/a/b/c/xyz.log -F perm=r -F key=log-access
But nothing is logging the Audit when wget is called from any other host. Can you please
assist on this further.
Thanks and Regards,Varun Gulati

If you are using a web service (httpd, etc) to service your files, then
make it authenticated and have it log.

Hi Team,
Thanks for the response. We are not using web services to provide/serve this file. Its
simply kept at a particular folder which people download using wget.
Here is the wget command users are using to download the file from the different hosts:
wget --no-cache http://servername/app/name/dist/xyz.zip
Still no logging is happening :(Need your expert help with this.
Thanks and Regards,Varun Gulati

You have to be. :-) If someone on another system uses wget to access a file on
the system you care about, something is serving the file on port 80. Maybe you
need to do a netstat -tanp to see what is serving the file.
Its simply kept at a particular folder which people download using
wget. Here is the wget command users are using to download the file from
the different hosts: wget --no-cache
http://servername/app/name/dist/xyz.zip

This should get you all access of that file if you are on a distribution that
enables the audit system unless you are on a special file system like NFS which
is not supported by the audit system.
> -w /usr/bin/wget -p rwxa -k Audit
This will show execution of wget on the server, not the client.

key=log-access
This is roughly the same as the first above just expressed in the longer form.

If you are using a web service (httpd, etc) to service your files, then

I agree on this point. Auditd will tell you that the web server accessed the
file but not who is getting it. Only the web server can know that.
