TECHNOLOGY ENHANCED LEARNING WITH OPEN SOURCE SOFTWARE FOR SCIENTISTS AND ENG...
This paper represents the evaluation and integration of Open Source Software (OSS) technologies to enhance the learning of engineers and scientists within the university. The utilization of OSS is essential as costs around the world continue to rise for education, institutions must become innovative in the ways they teach and grow Science, Technology, Engineering, & Mathematics (STEM) majors. To do this effectively professors and administrative staff should push toward the utilization of OSS and other available tools to enhance or supplement currently available tools with minimal integration costs. The OSS applications would allow students the ability to learn critical technological skills for success at small fraction of the cost. OSS also provides faculty members the ability to have students dissect source code, analyze network traffic, create virtual instances of real Operating Systems (OSs), and prepare students for low level software development. It is critical that all institutions look at alternatives in providing training and delivering educational material regardless of limitations going forward as the world continues to be more global due to the increased use of technologies everywhere. Through reviewing the available technology, possible implementations of these technologies, and the application of these items in industry could provide a starting point in integrating these tools into academia. When administrators or faculty debate the possibilities of OSS, gaming, and simulation tools this applied research provides a guide for changing the ability to develop future scientists and engineers that will be competitive on a global level in STEM fields.

Security
Overview of Windows Security
Windows security is used in many natural business settings. Windows Server incorporates features such as Encrypting File System (EFS), a feature allowing for encryption/decryption of files and algorithms as well as Access Management and Identity Protection, a feature that protects the policies and processes to control personal and private data. Windows Server uses networking security to combat viruses and provide network stability. Windows Server also uses secure messaging and collaborative solutions, such as SharePoint, for use when dealing with business partners (Adams, 2012).
Overview of Linux Security
Linux is an open platform allowing for users to add to the structure of the system. Strength in numbers helps Linux security in that security threats are often fixed right away and for all to see.
Why we choose Linux over Windows for Kudler Fine Foods, no system can ever be completely secure.

Security
Overview of Windows Security
Windows security is used in many natural business settings. Windows Server incorporates features such as Encrypting File System (EFS), a feature allowing for encryption/decryption of files and algorithms as well as Access Management and Identity Protection, a feature that protects the policies and processes to control personal and private data. Windows Server uses networking security to combat viruses and provide network stability. Windows Server also uses secure messaging and collaborative solutions, such as SharePoint, for use when dealing with business partners (Adams, 2012).

Editor's Notes
- IFL = Integrated Facility for Linux. It's a dedicated partition on a mainframe... From Steve Adams, ODOT -- To answer your questions, we are using Linux on the IFL for production CVS source repositories and a small (but critical) piece of custom code that I wrote to accept socket communications from CICS in support of the Digital Photo License (DPL) application. The code for DPL also includes a monitor application that's quite useful for collecting stats for daily transactions and troubleshooting problems when they occur. The work-load is mainly I/O bound with the notable exception of the monitor application, it's running under Apache, with a static compile of mod_perl, and custom Perl modules that I wrote to interface with the proc file-system. We also make use of the SMB and NFS protocols for DASD access and LVM for file services. We did a successful proof of concept connecting workstations to a 3270 emulator running in the IFL through ssh for client access to MVS. This work was significant since it secured an encrypted connection from the workstation to the emulator and all traffic from the emulator to MVS was local to the mainframe (nothing crossed the wire "in the clear"). We also found that the processor requirement of this concept was really quite light and most of the load was, again, I/O. In this effort we also tested connecting to Active Directory, RACF and running LDAP with a high degree of success. This work continues today but the scope is changing a little. In the very near future we will be migrating off of Red Hat in favor of SuSE/Novell (we have purchased and received SLES8 under our existing Novell agreement). This is probably going to take a bit of time and energy and takes priority over testing and concept work. Once this effort is complete we will be looking at hosting some X application on a guest to see if we can expect reasonable performance for thin clients.
