SELinux Red Hat Enterprise Linux 4 is the preferred platform for the most demanding security organizations in the world. Security Enhanced Linux is a completely new subsystem in Enterprise Linux and provides a superior security framework to what is available in traditional commercial IT operating environments. SELinux, developed with the U.S. National Security Agency, implements policy-based mandatory access controls to achieve more fine-grained security measures and greater flexibility compared to discretionary access control mechanisms. Privileges and policies for each service are specified rather than relying on the simple paradigm of users, groups, and a single centralized superuser account.
FINANCIAL SERVICES RED HAT ENTERPRISE
Usually characterized as conservative and resistant to change, the financial services industry has been challenged by financial technology (fintech) companies that compete by combining digital technology, social media, and big data analytics to replace traditional models with innovative, data-led approaches and modernized IT infrastructures. However, many financial services companies are burdened by obsolete, proprietary systems. To stay competitive, the financial services industry and its CIOs are increasingly turning to digital transformation to improve their IT infrastructures. In this partner solution detail, learn how Intel and Red Hat have collaborated to develop hardware and software solutions that support digital transformation.
Red Hat’s open source technologies deliver the high performance infrastructure needed in the financial services industry, where opportunities often grow faster than IT budgets. Our trusted, innovative solutions are built to help you become more agile and respond to market demands—whether in banking, wealth management, capital markets, or the expanding fintech sector.
Linux Deployment Strategies
Commercial products based on open source software have long enjoyed a symbiotic relationship with the open source world that is both cooperative and competitive. In the end, users benefit with a variety of product choices that range from free to commercially supported, enterprise-grade fee-based solutions.
Across that range of solutions, it is easy to presume that free solutions are by definition cheaper to own simply because the original acquisition cost ($0 out of pocket) is so compelling. While this might be a valid assumption if IT labor costs were also zero, as soon as an hourly value is attached to IT labor and end-user productivity, the cost associated with free products suddenly becomes much higher.
IDC research typically finds that the cost of operating system software is a relatively minor component of an overall total cost of ownership (TCO) analysis but that IT labor costs are generally a far greater contributor to TCO calculations. As a result, products that offer efficiency and productivity improvements for IT staff generally end up with competitive and often lower TCO metrics when all costs are considered.
This IDC White Paper compares organizations using a commercial Linux subscription from Red Hat to support their Linux servers with organizations that are using a mixed environment of both commercially supported and nonpaid Linux distributions and organizations that are primarily using nonpaid Linux distributions aboard their servers.
