Not an author, but there's a lot of overlap. Code bugs lead to breaches which lead to data theft and loss of privacy, namely.

Figuring out various strategies for tightening up that causality chain improves both security and privacy. Formal verification and security proofs of cryptography code. Provably correct software systems. Comprehensive testing. Using application or systems frameworks that have been developed with a security-first mentality, rather than security-bolted-on mentality (too many today use the latter). Etc.
