Hong Kong

The Hong Kong chapter was formed in December 2004. The objectives to establish OWASP Hong Kong Chapter are mainly because: -There are many web applications established in past 10 years. However, how many developers know that their developed application are secure. Meanwhile, there are many transactional-based systems, we should not ignore that the web application is another channel for hackers to compromise one's confidential information and interrupt any critical business operations.

- Raise the security awareness of web application development among the professionals.

- Encourage professionals to reference standard like ISO7799 for their web application security and post-deployment review as well as audit.

- Accelerate to Share, learn, discuss and review best practices of the experienced web application development security professionals even across various user groups (Java User Group and .NET User Group ) and security associations (i.e. PISA) in Hong Kong.

Coding Practice

- Mainstream web technologies (i.e. .NET, J2EE and PHP on Linux) security assessment

- Web application platform (i.e. Apache, IIS, Linux, Database) security assessment and review.

- Recent Web application security concerns.

- Regularly convey latest projects and presentations from OWASP.

News from Hong Kong Chapter
'''NEW!!!! Software Exploitation - It is about reverse engineering and exploit'''

'' I feel very honorable to invite Nguyen NAM to provide 2-day workshop on software exploit and reverse engineering. In fact, we met in OWASP Appsec Conference 2008 at Taipei and his team has won CTF (Capture The Flag) in Hack In The Box (HITB) 2008. It is really a valuable chance to have him to be in Hong Kong and this workshop is normally charged at 1000 USD per head. Meanwhile, there is NO such kind of workshop held in Hong Kong. Please reach me at anthonylai@owasp.org for reservation. ''

Fee 1000 HKD

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. It is good to prepare a candidate to join for Capture The Flag (CTF) event.
