Security Flaws Undermine SOA, Web Services and Networking Infrastructure
Security vulnerabilities with the OpenSSL toolkit can lead to buffer overruns, denial-of-security attacks, forging of digital certificates and compromising of confidential information. The OpenSSL problems follow
confirmation that cryptography researchers have broken the SHA, SHA-1 and MD5 hashes. Those flaws and recent cryptography breakthroughs heighten concerns about
digital certificates used for authentication and secure communications.

the structure of Java class files as a grammar. He explains why parsing the
binary class files is preferable to using XML and he provides an example
program for parsing class files.
SOA Programming and Registry/Repository Miko Matsumura explains that we can think of SOA programming in the
context of configuration, composition and customization. He discusses the role
of a registry/repository as an enabling technology for SOAs.

exploited it to its fullest potential. Dana emphasizes the use of declarative
programming instead of processing XML with imperative or procedural techniques.

XML-based messaging provides the plumbing for the development and
deployment of web services. Specifications from the World Wide Web
Consortium (W3C), OASIS, Web Services Interoperability (WS-I) provide
conformance guidelines for the creation of cooperative, interoperable
services.
Grid technologies allow us to partition problems and apply massive
computing power to their solution.
