The MOS for Marine Corps Security Force is 8151/52. This is a special MOS. Normally, the primary MOS is 0311, but it could also be any one of the other ground MOSs. The postion is a guard; however, aboard a Navy ship (usually aircraft carrier) and at embassies, the personnel who make up the MCSF contingent are also trained in Fast Reaction tactics, referred to as FAST. As far as the ASVAB score, it would be the same as a 0311. After completing bootcamp and then Infantry Training Battalion, and during your 1st tour of duty with an infantry unit, you will can apply to go go to MCSF training at Quantico VA. You will have to be one of the most squared away Marines in your unit. There is no room for error in the MCSF. The Quantico MCSF instructors are very stringent and rigid in their training curriculum. The make sure that only the best graduate.
I have provided the description for the MCSF MOSs below. It is a great goal that will start the day you check-in for bootcamp. Everyday in the Corps, do you absolute best in training and application of tactics. Take Marine Corps Institute courses after ITB. Always use your initiative to complete all required tasks before being told to do them. This is how you "shine" among your Marine Corps peers and how you will get approval for attending MCSF school.
