Re: [Fed-Talk] Paranoid or what



/usr/sbin/ocspd

This is the "Online Certificate Status Protocol" daemon that processes ALL Certificate Validation. This handles both CRL - Certificate Revocation Lists & OCSP - Online Certificate Status Protocol validation of certificates.

You configure which CRL or OCSP or even both CRL & OCSP validation you want your client to perform -- along with if it is required, off, or best attempt. This is configured under Keychain Access-- >Preference->Certifricates.

Mac OS X 10.4.x provides client-side OCSP, while server side is provided by one of the following vendor products of your choice:


CoreStreet		http://www.corestreet.com/
Tumbleweed		http://www.tumbleweed.com/

It is good to be paranoid, but this is not an item you need to be paranoid about...

Ok... this whole screen not locking after 10.4.4 and nobody else having the problem really concerns me.

I did a (at the shell) process monitor (ps aux), and didn't notice anything weird other than:

/usr/sbin/ocspd

There is no manual entry for it, and when run directly it just says "Abort Trap".... after a reboot, my machine now locks properly upon screen saver abort.

I'm not in a high security agency, but it strikes me as very peculiar that my computer sat all night on a screen saver and when I came in in the morning didn't require a password, even though I rebooted after the 10.4.4 update.

I use Filevault as well for file protection, but I am worried that perhaps a key logger or something may have been installed.

To my knowledge, to install an application they would still need my admin password, but they could install a binary application at the shell level and effectively install a key logger or some other type of malware without an admin password considering they potentially had access to my account and shell.

Does anyone know what this OCSPD application does? We had some linux machines at one time that got the "froggy" bug (showed up as frgy in process monitor) that would capture passwords and email them out.

Would it be overkill to rebuild my machine from scratch, or is there an easy way to determine if something has been placed on here to capture keystrokes, keychains, etc.
