Security plays a crucial, vital and is very critical part
that plays a major role towards web application and development services.
Therefore XML-RPC or SOAP both have no specifications that makes any explicit security
or authentication requirements to fulfill the need of web application and
development companies. There are main three precise security issues with Web Application
and Development Services that couldn’t be ignored such as Confidentiality, Authentication,
Network Security and Confidentiality.
What if a client sends an XML request to a server after that
the question is that can we make sure that the communication remains
confidential? The answer lies here that XML-RPC and SOAP run primarily on top
of HTTP as HTTP is used to support for Secure Sockets Layer known as SSL.
Message passing or communication can be encrypted via the SSL and is a proven
technology and broadly deployed but a single web application and development service
may contain of a chain of web applications and development services. For instance
one gigantic web application development company might altogether the
services of three other web applications and in this case SSL is not that
sufficient the communications need to be encrypted at each and every node along
with the service path and every node presents a potential weak link in the
chain. By the time there is no agreed-upon resolution to this problem but one
promising solution is the W3C XML Encryption Standard as this standard gives a
framework for encrypting and decrypting whole XML documents or may be just
portions of an XML document.
Come to the Authentication point of view and what if a
client connects to a web application and development service and how can we recognize
the user? Second question is does the user authorized enough to utilize the web
application and development services?
No as such clearance regarding this but still we can focus
on the following options that can be considered likewise HTTP consist of built-in
support for Basic and Digest authentication along with the services that can
therefore be secured in much the similar fashion as HTML documents are
currently protected.
There is currently no easy answer to the problem like
network security and is becoming debate day by day. Firewall vendors are now creating
tools to design to filter web service traffic.
