Web server/services hardening using SELinux
Instructor

Pavol Luptak

Duration

1 day

Summary

Security-Enhanced Linux (SELinux) is a FLASK implementation integrated in the Linux kernel with a number of utilities designed to provide mandatory access controls (MAC) through the use of Linux Security Modules (LSM) in the Linux kernel. SELinux generally supports many kinds of mandatory access control policies, including those based on the concepts of type enforcement, role-based access control, and multi-level security.

A Linux kernel integrating SELinux enforces mandatory access control policies that confine user programs and system servers to the minimum amount of privilege they require to do their jobs. This reduces or eliminates the ability of these programs and daemons to cause harm when compromised (via buffer overflows or misconfigurations, for example). This confinement mechanism operates independently of the traditional Linux access control  mechanisms. It has no concept of a "root" super-user, and does not share the well-known shortcomings of the traditional Linux security mechanisms (such as a dependence on setuid/setgid binaries).

This training provides basic concepts of SELinux, its differences to classical UNIX/Linux systems, describe security advantages of mandatory access control policies and teach how to effectively and rapidly configure a fully functional LAMP environment on SELinux system.

Secure Programming with Java
Instructor

Lucas C. Ferreira

Duration

1 Day

Summary

This training class will present best practices of secure programming in the Java language. It includes Java specific practices (i.e. how to avoid problems that arise from the compilation of Java source code to the bytecode language used by the JVM) and practices that may arise in other programming languages (with examples in Java). Some tools that may be used to verify the security of Java code and systems will be shown.

The topics include a quick overview of the OWASP Top 10, in order to contextualize the practices presented, and several best practices aimed at the different software layers. At the presentation layer, we focus on input validation, access control issues and dealing with exceptions. At the business objects layer, the practices deal with cloning and serialization issues. Practices to prevent command injection are presented at the persistence layer. Practices that should be used throughout all the software are also presented, including input data validation, class and method visibility, using and storing secrets, dealing with inner classes, overflows and boxing, and object initialization.

Audience

Java web application developers. This training requires basic understanding of web applications and an intermediate level of proficiency in the Java language and Object Oriented concepts. People with interest in other OO languages may also benefit from this training, but specific techniques, examples and tools used are targeted to Java.

OWASP Top 10 - What Developers Should Know on Web Application Security
Instructor

Sebastien Deleersnyder and Martin Knobloch

Duration

4 h To be scheduled on Tuesday.

Summary

Application security is an essential component of any successful project; this includes web applications, open source PHP applications, web services and proprietary business web sites. Web application security education and awareness is needed throughout the entire development and deployment organization. Each area and level of development or deployment organizations have specific needs and requirements regarding web application security education. A manager needs other information than a security professional or developer. Novices to the profession require other training than people with several years of experience.

The OWASP Education project aims to provide in building blocks of web application security information. These modules can be combined together in education tracks targeting different audiences. This Education Track provides in a 4 hour session covering what developers should know on web application security. It starts with an explanation of web application security and why it is important. Then the OWASP Top 10 is used to explain the nastiest vulnerabilities and how these can be prevented or re mediated. A secure coding initiative must deal with all stages of a program’s life cycle. Secure web applications are only possible when a secure SDLC is used. The SDLC is explained from the standpoint of people, processes and tools. Particularly for developers good secure development practices are covered in a separate topic. Finally the track finishes with an exhaustive list of web application security resources for web application developers.

Audience

Web application developers who are unaware there are security issues with contemporary web applications. No prior knowledge of web application security is assumed nor necessary. This track is independent of the coding language or web frameworks used; like PHP, JSF, Java EE or .NET. We must realize that web application developers are only one link - albeit an important one - of the chain that represents the security of a web application. This track aims to make that link as secure as possible, given the constraint of 4 hours. Another important aspect is that web application security should be tailored to the risk profile of an organization and the specific development environment of that organization.

Table of Contents

The challenge is to cover web application security in 4 hours to a web application developer. This is presented in such a way that the developers will be able to recognize and correct web application vulnerabilities in their projects.

Linux Software Exploitation
Instructor

Nam Nguyen

Duration

2 days

Summary

This course is a primer into software exploitation on the Linux environment. The course assumes only basic understanding of the Linux commands, and C programming with the standard library. It explains the computer architecture, assembly language then moves on to three basic classes of security bug: buffer overflow, format string, and race condition and methods to take advantage of them. Throughout the course, various examples are introduced with increasing difficulty so that participants will naturally realize the art of software exploitation for themselves.

This course does not discuss about shell coding. Except on one example where provided shell code is used as an illustration, all other challenges require only good analysis and calculation.

The course is conducted as a workshop with heavy interaction between participants and instructor. There will not be any presentation slide. Participants are to take note during the course.

Audience

Software developers, system administrators, security engineers with some experience in Linux and C programming.
