This book is a comprehensive guide to Java security issues. It assumes you are an experienced Java programmer, but have little experience with creating secure applications. This book covers formulating and enacting a network security policy to protect end-users, building e-commerce and database applications that can safely exchange secure information over networks and the Internet, cryptography, digital signatures, key management, and distributed computing: CORBA, RMI, and servlets.
