The book discusses Jakarta EE Security in relation to SE underpinnings and provides a detailed explanation of how client-cert authentication over HTTPS takes place, how certifications work, and how LDAP-like names are mapped to caller/user names. General (web) security best practices are presented, such as not storing passwords in plaintext, using HTTPS, sanitizing inputs to DB queries, encoding output, and explanations of various (web) attacks and common vulnerabilities are included.
Practical examples of securing applications discuss common needs such as letting users explicitly log in, sign up, verify email safely, explicitly log in to access protected pages, and go direct to the log in page. Common issues are covered such as abandoning an authentication dialog halfway and later accessing protected pages again.
