In a fast evolving online market place, businesses rely on technology to ensure
data, applications and customers' online transactions are fundamentally secure.
Simultaneously, online businesses grapple with security issues due to the high
volume of sensitive information they store and process. There are a number of
reasons for online businesses to adopt the latest cutting-edge Web 2.0 technologies:
Third-party integration without compromising security.
Relatively secure combinations of several technologies.
Scalability and Robustness
Cross-domain possibilities.
Ajax-based applications more flexible than page-centric.
Ajax and Flex applications are scalable without major architectural changes.
Fewer server interactions.
Security Features of Web 2.0 Applications
Web 2.0 applications like Google Calendar and MySpace.com cater to high-volume
user interactions by utilizing technologies like Flex, AJAX, etc. The sections
below discuss the inherent security aspects of different categories of Web 2.0
technologies.
Flex: Client-side
Applications developed using Flex execute within Flash Player and run inside
a security sandbox that prevents malicious attempts on application code. The
sandbox ensures that Flex is a standalone application, running inside a browser,
and prevents unauthorized access to the operating system environment as well
as other local instances of Flash Player. Flex has an extensive list of features
that ensures Flash content is secure, including:
Encryption capabilities of SSL in the browser encrypt communications between
Flash applications and servers.
Sandbox security system limits information transfer that might pose risks
to security or privacy.
Prohibits applications from reading from and writing to the local drive,
except for shared objects created by that domain.
Prevents web content from reading data from servers not in the same domain,
unless explicit access granted.
Enables user to disable storage of information for any domain.
Prohibits data from being sent from a camera or microphone unless the user
gives permission.
