I disagree. Remote OS authentication is not inherently insecure in Windows like it is in Unix. If you prefix the account names with the domain name, a user would not only have to spoof the username, he would have to spoof the domain name too. At that point, you probably have bigger problems than access to your database. Also, in that situation, only the security token is going over the network, not your password in clear text. The caveat is that you should be using the *domain name* as the prefix, not OPS$.
-----Original Message----- Sent: Friday, June 20, 2003 6:20 AM To: Multiple recipients of list ORACLE-L Hi Arup, Remote OS authentication whether with OPS$ or not is still a risk. You are intimating that SYSTEM is the only risky account involved here. What if any of the newly created OPS$ accounts have useful privileges. I have seen a similar application to the one described recently. There were forms within the application for administration and user management (in oracle, not the application) and the users who had access to these were assigned the DBA role and were of course external accounts. I think what you should add to your comment is that the issue is overrated is that any OPS$ / external accounts should not have any dangerous privileges granted and certainly not DBA. If you can guess the name of an admin account even if its OPS$ then the issue is still severe. cheers Pete -- Pete Finnigan email:[EMAIL PROTECTED] Web site: http://www.petefinnigan.com - Oracle security audit specialists Book:Oracle security step-by-step Guide - see http://store.sans.org for details. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Pete Finnigan INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
