This repository contains several Java web applications and command line applications covering different security topics.

#Web Applications in Detail Using Mozilla Firefox as browser is strongly recommended. The smaller web applications all come with a ready to use Tomcat7 Maven plugin which should be started via mvn tomcat7:run-war.

##CSRF-spring-security Cross-Site Request Forgery (CSRF) demo project preventing CSRF in a JavaServer Pages (JSP) web application by utilizing Spring Security. After launching, open the web application in your browser at http://localhost:8080/csrf-spring-security. A valid user is csrf with password csrf.

##CSRF Cross-Site Request Forgery (CSRF) demo project preventing CSRF in a JavaServer Pages (JSP) web application. Sample code is based on the Enterprise Security API (ESAPI). After launching, open the web application in your browser at http://localhost:8080/csrf.

#FerrisWheelManager Ferris Wheel Manager is a JEE 7 demo application containing security vulnerabilities like SQL Injection and Cross-Site Scripting (XSS). A datasource named jdbc/fwm is required, which must contain the tables/ data provided by SQL scripts in the Resources project. Valid usernames/passwords are Marvin/wheel (role Manager), Zaphod/ferris (role User). This web application was tested with Java Enterprise Edition 7, GlassFish 4 and MySQL 5.6.

#XSS Cross-Site Scripting (XSS) demo project preventing XSS in a JavaServer Pages (JSP) web application by utilizing input validation, output escaping with OWASP Java Encoder and the Content Security Policy (CSP). After launching, open the web application in your browser at http://localhost:8080/xss.

#crypto-spring Crypto demo project using Jasypt to secure Spring configuration (property) files. Requires a system property APP_ENCRYPTION_PASSWORD with the value spring-jasypt present on startup (set automatically by the Tomcat7 Maven plugin).

#security-header Security response header demo project which applies X-Content-Type-Options, Cache-Control, X-Frame-Options, HTTP Strict Transport Security (HSTS), X-XSS-Protection and Content Security Policy (CSP) (Level 1 and 2) headers to HTTP responses. This project requires a web container like Apache Tomcat (included via Maven Tomcat Plug-in). After launching, open the web application in your browser at http://localhost:8080/security-header or https://localhost:8443/security-header.

#session-handling-spring-security Session handling demo project utilizing Spring Security. Shows how to restrict access to resources (URLs) and how to apply method level security. Uses Spring Security to create and update the session id.

#Command Line Applications in Detail All projects contain main methods to get started.

##crypto-java Crypto demo project using plain Java to encrypt and decrypt data with asymmetric (RSA) and symmetric (AES) keys as well as to sign and verify data (DSA). All classes contain main methods to execute the samples.

##crypto-keyczar Crypto demo project using Keyczar to encrypt and decrypt data with asymmetric (RSA) and symmetric (AES) keys as well as to sign and verify data (DSA). All classes contain main methods to execute the samples. The latest Keyczar dependency is not available in any public Maven repo so far. Download the jar and add it to your local Maven repository manually.

##crypto-shiro Crypto demo project using Apache Shiro to encrypt and decrypt data with symmetric (AES) keys as well as hash data (passwords). All classes contain main methods to execute the samples.
