The Definitive Guide to Security in Jakarta EE
Refer to this definitive and authoritative book to understand the Jakarta EE Security Spec, with Jakarta Authentication & Authorization as its underlying official foundation. Jakarta EE Security implementations are discussed, such as Soteria and Open Liberty, along with the build-in modules and Jakarta EE Security third-party modules, such as Payara Yubikey & OIDC, and OmniFaces JWT-Auth. 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 u ...

Evolve the Monolith to Microservices with Java and Node
Microservices is an architectural style in which large, complex software applications are composed of one or more smaller services. Each of these microservices focuses on completing one task that represents a small business capability. These microservices can be developed in any programming language. This book shows how to break out a traditional Java EE application into separate microservices and provides a set of code projects that illustrate the various steps along the way. The sample projects highlight the evolution of monoliths to microservices with Java and Node. ...

Debugging with GDB
The GNU Debugger allows you to see what is going on "inside" a program while it executes - or what a program was doing at the moment it crashed. GDB supports C, C++, Java, Fortran and Assembly among other languages; it is also designed to work closely with the GNU Compiler Collection (GCC). The GNU Debugger Program has four special features that helps you catch bugs in the act: It starts your program for you, specifying anything that might affect it's behavior. Makes your program stop under specified conditions. Examines what happened when the program stopped. Allows you to experiment with changes to see what effect they have on the program. This book will show you: setting and clearing breakpoints examining the stack, source files and data examining the symbol table altering program execution specifying a target for debugging how to control the debugger how to use canned command sequences how to install GDB and much more! This manual is written for programmers. It is designed so someo ...
