Hi Everyone,
My name is James and this is my first thread...super excited

.
The reason why I am posting this thread is to ask experts like you guys for some career advice.
Right after obtaining a degree in M.I.S, I got a job at a well-known financial institution as a junior information risk analyst/auditor. I consider myself a truely lucky person to get a job like this without any prior experience in IT field. My ultimate goal is to pursue various IT info sec certifications e.g., CISSP, CISM, GSEC, etc.
My father used to work at SAP as a ERP marketing manager 8-10 years ago. Although time has changed I believe that SAP is still a dominant leader when it comes to ERP software considering many big firms use it. (I don't really know that much so please correct if I am not on the right track here...)
He suggested me to become an auditor specialied in ERP. And I don't think it is not a bad idea. Rather than becoming a broad and general-sound information risk analyst (although it can be specialized in someway), it might be better to be specialized in something, especially a software system. Because I have been strongly believing that you gotta be specailized in one thing to survive in this day of age. And I cannot think of anything better than ERP.
So I was wondering....
-Where should I start? I am still confused. SAP do offers courses and exams but I didn't know it was going to be that many. There was not a single "ERP exam".
-If I decided to be an ERP system auditor, would it be just a waste of time and money going after all those info sec certs? (e.g., CISSP, GSEC etc)?
-If not, how do those info sec certs can benefit me? that is, are there any other careers options related to ERP? not just an auditor
I am sorry if my questions are all ove the place.
And thank you so much for invaluable advice.
Cheers,

James
