Certification and Security in Inter-Organizational by Enrico Nardelli, Maurizio Talamo

By Enrico Nardelli, Maurizio Talamo

Certification and defense in Inter-Organizational E-Services offers the continuing of CSES 2004 - the second overseas Workshop on Certification and safeguard in Inter-Organizational E-Services held inside IFIP WCC 2004 in August, 2004, in Toulouse, France.  Certification and safeguard proportion a typical technological foundation within the trustworthy and effective tracking of performed and working tactics; they likewise depend upon an identical basic organizational and fiscal principles.  because the variety of companies controlled and accessed via conversation networks grows all through society, and given the felony worth that's usually connected to facts handled or exchanged, it really is severe with a view to certify the community transactions and make sure that the integrity of the concerned computer-based platforms is maintained. This number of papers bargains real-life program studies, examine effects and methodological proposals of direct curiosity to platforms specialists and clients in governmental, business and educational communities.  This booklet additionally files a number of very important developments.  The uptake of dispensed computational infrastructure orientated to provider provision, like Web-Services and Grid, is making C&S much more important.  E-services in accordance with legacy platforms controlled via self sustaining and self reliant firms, a typical state of affairs within the public management zone, elevate total complexity.  The elevated presence and use of e-service IT-infrastructures depends upon the serious skill required for all protection matters, from the fundamental (availability, authentication, integrity, confidentiality) to the extra complicated (e.g. authorization, non-repudiation), to trace obligations, --"who did what".

Example text

Better isolation is achieved by the Multitasking Virtual Machine (MVM) [CDOl] that particularly addresses the problem of executing different applications in the same Java virtual machine. MVM is a modified Java HotSpot virtual machine that shares application code wherever possible and replicates code where that is needed. In addition, native libraries, usually forbidden in safe Java environments, are contained by running them in a different process [CDWOI] than the MVM. MVM is closely related to the new Isolate API [JSROI, PCDVO21.

Either the generated code for each protocol must be verified to ensure equivalence to the specification, or the translation process must be proven correct and the mappings from specification language constructs to implementation code must shown to preserve the specification language semantics [WH99]. This paper is concerned mainly with the last two phases: implementation and implementation verification, as indicated in the boxed area of Figure 1. These phases produce the output of the development process: an executable program that conforms to the security protocol specification for which the desired security properties hold.

Default policy (complicates requirement 2) The system default policy, hidden in the Java virtual machine installation directory, should be revised and probably ovenvled by a more rigid policy file for the execution environment. For instance, Sun’s Java implementation comes with a system default policy that allows any thread to stop other threads. Dej%ulr threud seczirie (complicates requirement 2) Java’s default security manager offers little protection for user threads from other threads. Any thread in the Java virtual machine can find any other non-system thread.
