Help to privacy aware community

As I am finishing my Bachelor in computer engineering I would like to focus my career on cybersecurity, but there are a lot of branches (forensics, malware, pentesting, cryptography, etc.)

Which branch of cybersecurity would give me more useful knowledge that I could apply to the privacy tools and methodologies that we currently have? I would love to contribute in some open source project related to privacy at the same time that I develop my career skills.
