...Creating a usable secure operating system remains a critical research problem. Linux has several security developments included in its open source operating system. Among these are SELinux, chroot jail, and iptables to name a few. SELinux is Security Enhanced Linux. The National Information Assurance Research Laboratory of the National Security Agency was in charge of carrying out the research and advanced development of technologies needed to enable the NSA to provide the solutions, products, and services to achieve Information Assurance for information infrastructures essential to the security of the U.S. National Security. The Security-enhanced Linux prototype was developed by the NSA along with research partners from NAI Labs, Secure Computing Corporation (SCC), and the MITRE Corporation. Many other contributions have followed since the initial release.(NSA-National Security Agency, 2009) Researchers in the National Information Assurance Research Laboratory of NSA worked with Secure Computing Corporation (SCC) to develop a strong, flexible mandatory access control architecture based on a mechanism first developed for the LOCK system called Type Enforcement. The NSA and SCC then worked with the University of Utah’s Flux research group to transfer the architecture to the Fluke research operating system. The architecture was enhanced, when it was transferred, to provide better support for dynamic security policies. This enhanced architecture was named Flask. SELinux implements...

We looked and analyzed the Capacity of each station and the Utilization of same. The team ascertained our job completion and our Lead Time. Our strategy throughout the stimulation was to balance our work station and reduce the bottleneck. PRIOR TO THE GAME The team consulted and decided on the name of the team that would best suit the team. With much anticipation we reviewed all the literate that was provided subsequently to assist us in decision making at Littlefield Technologies. DAY 1 (8 OCTOBER 3013) Data was extracted from “plot job arrival “and analyzed. The information was used to calculate the forecast demand using the regression analysis. The next step was to calculate the Economic Order Point (EOP) and Re Order Point (ROP) was also calculated. A discussion ensued and we decided to monitor our revenue on this day. The strategy yield a positive response as our revenue was steady at this point. DAY 2 (9 OCTOBER 2013) Based on our initial analysis we continue to monitor our progress in term of our ranking and we further calculated the forecast demand using excel. The team then proceeded to take action and we selected Contract Two (Maximum Lead Time One Day). The Re-Order point was changed to 35 batches of 60 kits to ensure...

The company, RIM (Research In Motion) makers of BlackBerry were at one time the leaders of the smartphone market. In 2011 BlackBerry owned 11.1% of the market, Apple had the second largest share with 18.2% of the market, and with Android leading at 49%. BlackBerry’s plans to launch the playbook two and the new operating system in the coming year. Despite their efforts to change the company, many expertises argue there is no room for a new operating system in the smartphone market, especially with the release of Microsoft’s Windows 7 phone. This article is related to our discussion about leadership in our class. The company, BlackBerry is receiving new leadership who faces the challenge of competing in the smartphone market. The announcement by Jim Balsillie, the new CEO of RIM is related with leadership, especially visionary leadership. The leader with a vision is better equipped to handle challenges they face. Although the new CEO of the company is not pushing forward to radically change the business he acknowledges their business is falling behind in smartphone competition and has a new plan to survive the challenge. Vision provides where to go and a great control over the...

...Manzana Insurance The Fruitvale branch is not faring well, they are behind competitor Golden Gate in new policies(375 to 326 in favor of Golden Gate), endorsements(300 to 206 in favor of Golden Gate), renewals (1,400 to 1,063 in favor of Golden Gate), turnaround time (2 days to 6 days in favor of Golden Gate), and renewal loss rate (15% to 47% in favor of Golden Gate) in the most recent quarter. The number of renewals, and endorsements at the Fruitvale branch are lower than they were for the same quarter the previous year, and the turnaround time, number of late renewals, and renewal loss rate have increased. The Fruitvale branch has performed especially poorly during the 1991. The main cause of the problems is that the Fruitvale branch processes RERUNS last because they are seen as less profitable than new policies. When RERUNS aren’t provided by the due date, it displeases customers and causes them not to choose to renew the policy with Manzana. In a market where prices are essentially identical, customers value the service they receive and how fast their requests can be processed. Therefore, since the Fruitvale branch is falling behind in this regard, the renewal loss rate is at a record high. Additionally, if a renewed policy is late, the insurance agent is likely to suggest another agency to customers, thus adding to the low retention rate. To make matters worse, only 15% of RAPs become RUNs, so they aren’t acquiring a large number of new...

...system safe and secure for users. Security-Enhanced Linux (SELinux) is a security feature that was developed by the National Security Agency (NSA) of the United States of America. As the agency itself states, “The National Security Agency has long been involved with the computer security research community in investigating a wide range of computer security topics including operating system security” (Security-Enhanced Linux - NSA/CSS. 2009). As long proponents of computer security, the NSA worked to develop SELinux. SELinux is an application of the FLASK architecture, which provides Mandatory Access Control (MAC) as part of the operating system kernel. According to a paper presented at the 2001 Ottowa Linux Symposium, “The security policy decision logic has been encapsulated into a new kernel component called the Security Server (SS)” (Loscocco and Smalley. 2001), this allows the kernel to enforce policy decisions without needing direct access to the policy itself. SElinux provides MAC measures to secure data, files, directories files, network interfaces, and all other components of a Linux operating system. SELinux is designed to address many security holes in a computer system including “...preventing processes from reading data and programs, tampering with data and programs, bypassing application security mechanisms, executing untrustworthy programs, or interfering with other processes in violation of the system security policy.” (SELinux Frequently Asked Questions...

...theft and identity theft. This paper will explain a few of Unix/Linux’s security operations such as SELinux, Chroot, and IPtables. Security-Enhanced Linux is a Linux feature that provides a mechanism for supporting access control security policies, including United States Department of Defense style mandatory access controls. These functions were run through the Linux Security Modules in the Linux kernel. It is not a Linux distribution, but rather a set of modifications that can be applied to Unix-like operating system kernels, such as Linux and that of BSD. SELinux was developed by the United States National Security Agency, it was released to the open source development community under the GNU GPL on December 22, 2000. SELinux users and roles are not related to the actual system users and roles. For every current user or process, SELinux assigns a three string context consisting of a role, user name, and domain. This system is more flexible than normally required: as a rule, most of the real users share the same SELinux username, and all access control is managed through the third tag, the domain. Circumstance for when the user is allowed to get into a certain domain must be configured in the policies. The command runcon allows for the launching of a process into an explicitly specified context, but SELinux may deny the transition if it is not approved by the policy configuration. The security of an unmodified Linux system depends on the correctness of the kernel, all the...

This chapter examines the vertical dimension of structure—the hierarchy of authority created to control an organization’s members. How and why does vertical differentiation occur? The Emergence of the Hierarchy The hierarchy emerges when an organization faces coordination and motivation problems due to increased level of differentiation. At this point, the hierarchy emerges to coordinate and motivate members by increasing the number of managers and organizational levels. This gives the organization direct face to face control over its members. Managers choose between a flat hierarchy with few levels relative to company size and a tall hierarchy with many levels relative to size. Problems with Tall Hierarchies A hierarchy is tall if it has many levels relative to organizational size and flat if it has few levels relative to size. Most large companies do not exceed 9 or 10 levels and do not increase the number of managers, because tall hierarchies have problems with A) Communication Problems. As the chain of command...

...Modularization, Commodization Modularity Definition: Modularity is a very general set of principles for managing complexity. By breaking up acomplex system into discrete pieces—which can then communicate with one another onlythrough standardized interfaces within a standardized architecture (Langlois, 2000) * Modularity is based on a systems theory view of organizations and their processes. It seeks to investigate how a system’s components are ‘coupled’ together and how tight these bonds are. * Modularity is important today because of the increased complexity of modern technology. * The driving normative basis for the investigation is that increased modularity enables the parts of a system to be separated and combined with much greater flexibility, and that such flexibility is desirable. * What is new is the application of the idea of modularity not only to technological design but also to organizational design. * A complex modern society might be made more productive through a modular design of social and economic institutions. * In a world of change, modularity is generally worth the costs. The goal is to find the modularization that minimizes interdependencies and most cleanly decomposes the system. * Innovation that takes place through change in the modules we can call modular innovation. * Handling complex systems become easier if break them up into sub-systems. * Complex product or process composed of smaller sub-systems that can be...

...and the need to sustain it, the timing is right to diversify revenue streams and monetize the Android platform through the manufacture of integrated Google phones. This recommendation is important as a means of protecting Google from experiencing the preverbal paradox of success. Moving into mobile manufacturing also helps diversify Google’s revenue stream as Google finds itself losing advertising revenue to other websites, such as Facebook, Netflix, and others. Thus, beyond the importance of protecting Google’s right to make the Android operating system through the acquisition of 17,000 patents, a move which ultimately protects and fuels ad revenue, the Motorola acquisition should be utilized as an opportunity 1) to create a new source of revenue, 2) protect against the dependence on licensees, and 3) to lead long-term strategic initiatives by being a more nimble “integrated-gadget” model. 3.

...Overview of the Chapter This chapter examines the nature of organizational control and describes the four steps of the control process. It also discusses three types of systems available to managers to control and influence organizational members: output control, behavior control, and organizational culture(clan control). Effective management of organizational change is addressed, as well as the role of the entrepreneur in the change process. LEARNING OBJECTIVES • Define organizational control and identify the main output and behavior controls managers use to coordinate and motivate employees. (LO1) • Explain the role of clan control or organizational culture in creating an effective organizational architecture. (LO2) • Discuss the relationship between organizational control and change and explain why managing change is a vital management task. (LO3) • Understand the role of entrepreneurship in the control and change process. (LO4) MANAGEMENT SNAPSHOT: CONTROL IS NO LONGER A PROBLEM FOR ORACLE One of the main advantages of Internet-based control software is its ability to centralize management of a company’s widespread operations, thereby allowing managers to easily compare and contrast the performance of different divisions spread around the globe in real time. Oracle, the second largest independent software company in the world after Microsoft, did not have such a system in place and therefore was not experiencing the cost savings that...
