Career Change from Accounting to IT

I am currently an unemployed accountant. However, I am 25 and recently graduated college with a BS in Accounting. I have been looking into getting certs like the MCSE or CCNA.

I am not completely sure what area of technology I want to go into, but I am interesting in IT Security or Software Development. What would be the best way to initiate my career change? Should I go back to school and get a degree in computer science?

I preferably want to get certs do some internships, then go back part time for my Masters.
