Project Goals
• Can a single sign-on realize multilevel security?
• Investigate Portlet Technology, in particular Java
Specification Request (JSR)168, to determine if
it would facilitate sharing data, at different
security levels
• Avert the information flow problem, i.e. use a
single sign on to access to multiple levels of
classified resources, without compromising the
multilevel security policy.

Rationale and Relevance
• The events on September 11, 2001 which
spawned the 9/11 commissions report
• Hurricane Katrina and Rita in 2005
• Personal experiences

J2EE vs. .NET
• When it comes to building distributed web
applications which can interoperate
seamlessly between components in
platform-neutral way there are two leading
technologies competing for your vote,
J2EE and .NET (pronounce “dot NET”).
Patrick Cook

.NET
• .NET is a Microsoft centric approach that
runs on Windows platforms but does not
fully comply with other operating systems.
• .NET is still in its infancy with respect to
Java and has not reached its “tipping”
point with many vendors.

J2EE
• J2EE is a platform-independent solution
that uses the Java programming language
and provides support for major operating
systems
• J2EE is widely supported amongst major
vendors
• W.O.R.M
– Write once run many times

Java Portals
• A Java portal is a J2EE conformant
technology which aggregates resources
from disparate systems into a common
operating environment over the web. It
generally allows individualized
customization, facilitates single sign-on
authentication and is designed to run on
multiple platforms [JSR168].
Patrick Cook

Portlets
• Portlets are web components that
generate dynamic content in an
autonomous fashion. The autonomy is
generated by markup fragments such as
HTML, XHTML, or XML, but the
aggregation of the fragments are managed
by a portlet container.
Patrick Cook
JEEMA
12
Portlet Container
• In general, a container is software that
provides “out of the box” services which
developers can leverage for initialization,
creation, and deletion, as well as, resource
and dependency management [JBOSSP].

JSR 168
• Java Specification Request 168, originally
released in October 2003, provides the
blueprint for developing portal
components.
• Portlet Application Program Interface (API)
– Portlet
– PortletConfig
– GenericPortlet

Java Enterprise Edition Multilevel Access
Web Portal
What is JEEMA?
• JEEMA, Java Enterprise Edition Multilevel
Access, is an acronym for a Java 2 Enterprise
Edition (J2EE) compliant web portal that
champions portlet technology to facilitate single
sign-on authentication to access resources with
multiple security levels
• JEEMA is based on the Java 2 Platform,
Standard Edition, which adheres to the Java
programming language and libraries

JEEMA implementation of IPC
• Java Messaging Service API’s
• Uses the “listenTo” attribute in establishing
interportlet communications.
• Whenever a portlet is added to a portal, it
creates an “instance” this instance has an
instance label which other portlets listen to

JEEMA Reliability
• The reliability of the system, R (m), is
measured in terms of its ability to deliver
reliable messages to its recipients as
portlets increase within a web portal.
• This can be defined mathematically as
R(m) = p/ m, where p is equal to the
number of reliable messages and m is the
total number of messages.

Lessons Learned
• The challenges related to remote
development (“The virtual team”)
• Black Box Coding
• Implementing JMS on SunOne and JBoss
– JNDI
– “Asynchronous” Communication

Conclusion
• A single sign – on can realize multilevel
security
• The technology is not mature enough in its
current form for an enterprise solution that
used for National Security
• It does provides a stepping stone toward
upward mobility in MLS solutions
