IBM WebSphere Application Server Version 8 for Linux on IBM System z - SSL Setup and Performance Study

Abstract

This paper describes how the advantages of the System z cryptographic hardware features with IBM WebSphere Application Server (WAS) Version 8 for Linux on System z can be exploited when SSL encryption is used to secure the external communication. It also provides setup guidelines for Java-based workloads.

Exploiting IBM System z Cryptographic Hardware using JSSE

Abstract

This study measures performance and throughput for the Java Secure Socket Extension (JSSE) on Linux for IBM System z with Java 2 Platform, Enterprise Edition.

Data encryption is an important feature to ensure privacy and integrity of data sent using any type of network. This paper describes how to set up the cryptographic environment on IBM System z to obtain the benefit of the additional power of special purpose features CPACF and CEX2A using a client-server based Java application communicating using SSL with different cipher suites.

Tivoli WebSEAL - Sizing and capacity planning

Abstract

WebSEAL provides an authentication and authorization mechanism based on Tivoli Access Manager. It enables an end-to-end Single Sign On (SSO) solution for secure transactions for WebSphere application servers.

Here WebSEAL is used as proxy inside a DMZ from a secure WebSphere Application server environment. Each server runs on virtual hardware under z/VM.

The paper describes how to setup the environment and how it performs in various scenarios. Additionally it shows the impressive advantage of the IBM system z cryptographic hardware features CPACF and CEX2C cards and how to setup the system to get cryptographic hardware support. It also demonstrates that the implementation of a DMZ with all its services and servers is a very good case for server consolidation on z/VM.

Performance of a webApp.secure environment

Abstract

WebScurity's webApp.secure™ protects Web application servers from Internet attacks. This utility of the IBM System z Linux Utility Services is a strategic direction, protecting Web applications from attacks in addition to traditional firewall and perimeter security.

This paper determines the performance of a webApp.secure environment. It shows that the implementation of a DMZ with all its services and servers is a very good case for server consolidation on z/VM.
