Data Security for Java Applications
Every software engineer should have a decent understanding of data security coding techniques and regulatory requirements. Learn how to avoid data breaches in your Java projects and stay fully compliant to common data regulations.
What you'll learn
Modern Java apps often leak data through weak password storage, brittle crypto, noisy logs, and overshared downloads. In this course, Data Security for Java Applications, you’ll learn how to design and implement end-to-end protections following industry best practices. First, you’ll explore strong password handling with adaptive hashing and upgrade policies. Next, you’ll discover practical data protection with AES-GCM, generate cryptographically strong PINs/IDs, and deliver sensitive files via short-lived, single-use links. Finally, you’ll learn how to secure logging and implement generic error handling that aids diagnosis without leaking secrets. When you finish this course, you’ll have the skills and knowledge of data security needed to build audit-ready services that resist cryptographic failures and data exposure.
