Are you using proprietary operating systems and/or software? Open source? You could be in for a very nasty surprise. When it comes to software asset management, it is critical that you read your license agreement closely. You will most likely discover that you are responsible for any copyright violations found within the code--even if the software publisher made them. This is such a simple concept that many of us miss it altogether. Software is made up of millions of lines of code. An enormous percentage of that code can come in the form of building blocks--chunks of code that the software builder simply plugs in to the rest of the application. If the software publisher--or, more accuratley, the developer/code writer--fails to ensure the license to use a given block or code, YOU, the consumer, could find yourself liable for the copyright violation.
Read the license. The clause is there. I guarantee it. If at all possible, you need to either negotiate the clause out or negotiate an addendum to the license limiting your exposure. Or you could just ignore my advice and wait for an audit.
