Re: Unknown user found in AD and SonicWall

You could also setup a host IPS on the affected server.  OSSEC is an open source HIPS that will also monitor logs and 
alert in real time when defined events occur.  I've been faced with similar situations over the years.  The thing to 
get management to understand is that the network and servers are property of the company, not the vendor.  The vendor 
must comply with proper security defined by your IT dept, not by the vendor.

In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are
