in FIX 4.0 Does SecurityID and Symbol refer to the same Stock. The only difference is SecurityID is refer to some international common naming standard for the same stock. Like CUSSIP, ISID cdoe…etc.
Is it a one-to-one relation between SecurityID and Symbol?

Symbol and SecurityID refer to the same security (e.g. a stock). SecurityID is paired up with IDSource. IDSource specifies the type of SecurityID value such as ISIN, CUSIP, Sedol, etc. The Symbol field contains a "ticker symbol". Often times computers look at SecurityID and humans look at Symbol. If you have a situation in which you only have one applicable symbology source, then you can populate the Symbol field with the same value as SecurityID.
