Question on Artificial Intelligence vs Security

<p>I am currently doing a computer science major at University of Maryland. The CS program there allows you take take a few different paths as a CS major. I am a freshman so I still have time to decide but I've narrowed it down to Security or AI. I am beginning to lean towards the AI specialization. Would AI require that I get a PhD or go to grad school? And would security require a PhD or grad school?</p>

<p>Thanks!</p>
