In game terms, that means SINner, licenses (REAL ONES!) for all your weapons, programs, and gear, and a license as a bodyguard. That being said, if you have the SIN, the rest shouldn't be that difficult. Everyone needs a bit of muscle.
Of course, it is even easier to be just hired muscle, without the pesky licensing. Afterall, who asks the guy standing between the corp bigwig and the 'terrorists' for registration on their weapons, unless they're using something clearly out of the ordinary, like heavy weapons or gas grenades?
