Everyone says to specialize in your graduate degree, what did you specialize in?

Thanks to everyone that has posted in the how did you become a business owner and what got you into IT, I have really enjoyed reading about everyone's history. I just finished my AAS in CIS and am starting on my BA in the fall for Computer Science. Everyone has been saying to specialize when you get to the graduate level and I am wondering what did everyone specialize in? I like networking and am thinking of Information Security. I want to get a good job and I am just wondering what are good areas to specialize in because I really don't know what all is out there. Thanks everyone!
Taking 70-294 very soon...again

Many schools are now offering this type of degree 100% online and some schools in hybrid online/campus components.
My suggestion to you and I wish someone would have told me this: if you're even thinking of getting a graduate degree, pick one several semesters before you're done with your Bachelor's and find out if you're meeting all requirements to get in. If you are, find out if you can start taking any graduate courses while you're still in your Bachelor's program. These things can keep you on the right track and give you a good head start. Don't trust your advisers to do it for you.

Don't let the poor website design turn you off though :)P
In any case, my current path (option IV) takes me through a nice, balanced mix of electrical engineering and computer science classes, so I have plenty of time to figure out if I want to specialize in EE or CS when I get to grad-school.

Free DevOps/Azure Resources: Visual Studio Dev Essentials
Let it never be said that I didn't do the very least I could do.
That one used to offer in state tuition for online students whether you were in Illinois or not... not sure if they still do. I actually enrolled about 5 years ago but canceled at the last minute because something came up (I don't remember what) and I knew I wouldn't have the time to dedicate to it. Looked like a great program though.
Recent: 11/2019 - RHCSA (RHEL 7); 2/2019 - Updated VCP to 6.5 (just a few days before VMware discontinued the re-cert policy...)
Working on: RHCE/Ansible
Future: Probably continued Red Hat Immersion, Possibly VCAP Design, or maybe a completely different path. Depends on job demands...
These universities also provide MBA degree.
