Java Training Overview
This course exposes students to the broad range of challenges and techniques that is "Java security." As there is not one security problem for Java applications and components, but many, so there are many diverse solutions, found in various places in the Java architecture. This course starts with basic concepts of code security -- access controllers, permissions, and policies -- and good secure-coding practices. It introduces key and certificate management and code signing, and takes students through exercises in basic cryptography skills using the appropriate Java APIs; but then the heavy focus is on the Java Authentication and Authorization Service, or JAAS, and its increasing role in J2EE security.
The course emphasizes hands-on exercise, and students will spend more than half of their classroom time solving specific security problems. Most labs are organized as scenarios in which a security breach of existing software is possible - students begin by hacking the system in some way. Then the work of the lab is to tighten up the software to eliminate the threat: set a secure policy, sign a file, clean up overexposed parts of an API, require user login, etc.
Java Training Prerequisites
- Solid Java programming experience is assumed - both structured and object-oriented techniques.
- Some knowledge of J2EE architecture and development is also required, though extensive practical experience with J2EE development is not strictly necessary. Our Course offers a one-day overview of J2EE development, including architecture and working examples..
Java Training Learning Objectives
After completing this course, the student should be able to:
- Understand how the Java language and standard-platform architecture solve many low-level security problems for all Java code.
- Design and implement security policies for Java applications, servers, and components.
- Manage keys and certificates for a Java application, and sign code sources as necessary.
- Practice secure design and coding, and balance usability with security in UI and API.
- Sign and verify application data and messages using the JCA, and encrypt/decrypt using the JCE.
- Incorporate JAAS authentication into an application.
- Implement a JAAS LoginModule to connect to your own application data.
- Secure J2EE applications by URL and role, and integrate JAAS authentication.
