What languages should I learn as a cyber security major?

Question

I am a senior cyber sec major at DePaul, and have taken classes in java, c, and python. I am pretty good with them but not an expert. Would anyone with experience in Windows/Linux/Network security be willing to enlighten me on the programming languages I should be focusing on going forward, and their relation to enterprise security? What types of tangible projects should I be working on? What should I start putting on my vms?
