Auditing without Trusted System

Is there a way to audit files/directories/logins without enabling trusted system?

Re: Auditing without Trusted System

Let me clarify... audit directories

using the following audits:
Admin
Close
Create
Delete
Modaccess
Moddac
Open
Process - is it possible to restrict this to processes generated by command line access from a login? (i.e., I don't necessarily need to know about automated app processes, just commands run from a login shell)
Removable
Login


Thank You

Re: Auditing without Trusted System

From what I read you cannot audit an hpux server without converting to a trusted server, but maybe these threads can be of help:

and this document:

Tonya,

Are you running 11.11 or 11.23 ? It is possible to enable auditing in 11.23 without converting the system to trusted.

But why would you not want to trust the system ?

11.00 :(

My customer has stated that it will cause problems with the applications. We are trying to understand the reason why, but this information is difficult to get.

Re: Auditing without Trusted System

OK... so we must trust!! :)

Can I turn on auditing selective filesystems? Turn off auditing on some filesystems? How?

Thanks,

Look at this document for more information on auditing:

Re: Auditing without Trusted System

Yes, I've read that document. It does not address this issue. Does all this silence mean nobody knows? If there is a way, I do not see it documented. I was hoping someone had found a flat file you can modify, something...

Re: Auditing without Trusted System

The choices for auditing are shownj in SAM. Since auditing occurs at the kernel level, individual files and directories can't be differentiated. You can audit reads and writes (which the kernel understands) but the actual filename is part of the user space. A user program requests that a file be opened by communicating with the LVM and filesystem code and gets back a file descriptor block. Reading and writing that file requires the filesystem code to translate the record in the file into an lvol block and the LVM code translates this into an actual kernel read/write request for the disk (which can be audited).

I see... that explains it. Thanks!
