Visa Rejection due to security reason

I am currently in Abu Dhabi UAE on a visit visa. My company applied for a work permit for me but it was rejected by immigration citing "security reasons". I don't know how to resolve this. I went to Abu Dhabi immigration office but they didn't provide any further information to me. now the company is willing to re-apply but no one knows the exact issue of why it got rejected in the first place. All my documents are fine, I have no case, debt, or anything like that in my name. The company is not helping anymore. I just want to know how can i clear my name and first of all how do I find out the exact reason in the first place?
