Java
The two-days Java security workshop covers the fundamentals of secure coding in a web-related environment. During the course, developers learn how to find vulnerabilities, how to identify them within the source code, how to avoid, and how to mitigate them. We believe that developers understand security concepts at best when it is presented in their own programming language, therefore in this course, every example (except HTML and js specifics) are demonstrated via Java code.
Doing exercises is the most fun and most effective way of learning security concepts, and so during the workshop, the attendees will identify and fix security vulnerabilities in Javulna, a deliberately vulnerable Java application, developed by us (available on Github).
The course covers the following topics:
Secure-coding principles
Injections (SQL, XML, LDAP, path-traversal, etc...)
Other server-side vulnerabilities (XXE, CSRF, Billion laughs, RFI)
Java-specific (overflows, type-safety, serialization, Java Security Manager, Java-coding best-practices by SEI CERT)
Client-side vulnerabilities (XSS, HTML injection, Clickjacking, Tabnabbing)
Http security-related headers
Security of the most fundamental authentication and authorization schemes.
We can on the fly flex the training to meet the level and the experiences of the audience.
Based on their previous knowledge and interest attendees can further choose from the following topics:
Security of OAuth and OpenId
Cryptography basics
Cryptography of the web (TLS, certificate pinning)
HTML5 security
Security of some JS frameworks.
Auditing of the attendees' own source-code, identifying security best-practices of their specific technologies can be part of the two-days workshop, or extended to an additional day (see Related courses below).
title: Secure development in Java/JEE
audience: senior/medior developers, lead devs, testers and security champions (mostly comprehensible for juniors as well)
duration: 2 days (12 hrs education time) in the standard case, 3 days if combined with additional modules (see the Related courses below)
Java specific parts are developed by: Péter Nyilasy
Many parts developed by: Glenn ten Cate, Marek Zachara
We assume that the developers attending the Java secdev course:
are familiar with the Java language and with JEE
understand the HTTP protocol, HTML and Javascript
are familiar with basic security features of an enterprise application (authentication, authorization, the concept of a session)
have Java (JDK) and a suitable IDE installed on their laptop (labs desktop)
DIY code and ASVS audit
'Into the middle of things' hands-on hacking
Playing with untuned source code scanning
Playing with identifying real threats and security requirements
OWASP ASVS topics, an introduction to the areas to protect
How a properly designed infrastructure architecture should be built
Setting up the right security requirements
Create and train security champions
S-SDLC basics, secure development as integral part of SDLC
Automatic tools and their values, non-automatic tools, pentests, peer code review, assisted code-review
Injections: SQLi, XML injections, JSON, XPath, XSS, cookie injection, open redirection, http header injection
Path traversal, XXE, Buffer overflow, Zip bomb, Million laugh, RFI, Insecure file upload, Code execution
Insecure direct object reference
XSS (types, impact, causes, defenses, other html injections, BeEF)
CSRF, Clickjacking, Same-origin policy, CORS
Tabnabbing
Input validation vs encoding
Security logging, exception handling
Threat modelling
Separation of duties, trust boundaries, security boundaries, defence in depth, principle of least privilege, minimising the attack surface, risk driven mitigation
Business logic vulnerabilities
Cryptography basics
TLS, ciphersuites
HTTP certificate pinning
Perfect forward secrecy, certificate transparency
CSP, HSTS, Cookie settings, x-content-type-options
Authentication principles, session management, authorization
RESTful authorization (OAuth2, OpenID Connect)
JSON web tokens, JWT
API security, design and implementation
Web service security [optional]
Attack surface
Audit support (separate audit logs, managing debug logs)
Intrusion detection, correct reactions
Protecting the admin interface
Developed by Péter Nyilasy
Java security manager
Java language security (is Java a secure language?)
Java-specific issues
Numeric overflow, automatic conversions
Serialization, JPQL
SEI CERT Oracle Coding Standard for Java
Cryptography in Java
Angular JS/TS
Polymer
React
Local storage/session storage
Web messaging, web sockets
Practicing is part of many of the above blocks. We start off basic hacking challenges, but the real exercises are about fixing vulnerable codes, and tasks when attendees need to assess code and an application on their own. We mostly offer cloud based facilities to run the exercise environments, so no local installation is needed.
For most of the courses there are intentionally vulnerable applications which we use to demonstrate and learn specific vulnerabilities and how to fix them.
In some cases we use public "damn vulnerable" applications, in some cases we prepared our own applications to practice with.
We assume that developers should be capable of running basic automated tests against the security of their codes on their own. And also be able to tune the SCA tools to produce reasonable false positive and valuable findings ratio.
Normally we teach how to use security plugins of Sonarqube.
We provide sample codes to test. Though the best experience is achieved when developers run the security SCA against their own codes.
See also the extra, on-demand block of 'Assisted code-review lab' below for practicing on your own codes.
OWASP ASVS is the current standard for assessing the security quality and design flaws of a (web) application, and it's the developers who know the answers to the ASVS audit questions. So we take developers to a short journey in assessing the security properties of their applications.
