...process of hardening your network. Hardening is where you change the hardware and software configurations to make computers and devices as secure as possible. I choose the network layout workgroup. First with the workstations and laptops you need to shut down the unneeded services or programs or even uninstall them. I would also have installed reputable anti-virus software on the workstations. You also need a hardened image for all of your workstations. To do this you need to install a new copy of the operating system and then begin the process of hardening it. After you have one good hardened workstation you can use it as a model for all other workstations and laptops. As for the router you definitely need to protect it from unauthorized access. The router needs to be password protected and you should periodically change that password for added protection. For the cable modem you should keep all unwanted and unused ports closed. I would also schedule a regular scan of all the systems as part of my maintenance processes. These processes and procedures apply for all hardware devices. Disable remote administration, administration of your router / access point should be "local only", namely, there is no reason to let people from another country have access to your network hardware and If you need to make changes, you should be local to the device. Update the firmware. Believe it or not, consumer network hardware needs to be patched also. Check the support site of the vendor of the device...

...Mac Memory Management For rough draft Mac OS is available on two processor architectures: the Motorola 68k series and the PowerPC. Mac OS has a flat address space, shared between all processes. There is no per-process memory protection. Application code runs in supervisor mode, so there is no instruction protection. Mac OS has virtual memory, in the limited sense that a larger fixed address space can be simulated, by storing the entire address space on disc. This size of this address space is fixed at boot time. The lowest part of memory is occupied by the system partition. This contains some system global values which applications should not access directly, although there is nothing to prevent them doing so. Historically, the Mac OS used a form of memory management that has fallen out of favor in modern systems. Criticism of this approach was one of the key areas addressed by the change to OS X. The original problem for the engineers of the Macintosh was how to make optimum use of the 128 KB of RAM that the machine was equipped with. Since at that time the machine could only run one application program at a time, and there was no fixed secondary storage, the engineers implemented a simple scheme which worked well with those particular constraints. However, that design choice did not scale well with the development of the machine, creating various difficulties for both programmers and users.

...are dedicated to a single role that does not require and added applications or services. One example for when Server Core is applicable is for running a single server role such as a DNS server that requires no graphical user interface or extras to operate. The security benefits do indeed outweigh the inconvenience of having no graphical interface because you will typically be running Server Core on a server with a single role that is vital to the network, in which keeping it stable and running has a high priority. So sacrificing a bit of convenience to better protect these servers and maintain the job they perform. A virtual server is just as its name suggests a server that only exists in virtual space; it’s basically an operating system...

...Is Microsoft a Monopoly? Preliminary version April 4, 2000 Steven Cuellar Department of Economics San Jose State University San Jose, CA. 95129 Phone: (408) 924-5408 E-mail: SCuellar@email.sjsu.edu Presented at the Department of Economics Seminar San Jose State University San Jose CA. 95129 April 7 th 2000 Is Microsoft a Monopoly? 1 This would occur in the case natural monopoly in which economies of scale result in a single firm producing at a lower cost than a large number of smaller competitive firms. 1 Since the beginning of the antitrust trial against Microsoft there has been a great deal of commentary and analysis concerning the market position, pricing and strategic behavior of Microsoft. The courts Finding of Fact and the recent Conclusions of Law have intensified the interest in the case and resulted in even more analysis and questioning of the courts findings. This paper adds to the current list of Monday morning quarterbacks questioning among other issues: Whether or not Microsoft is a monopoly? Did they violate the antitrust laws? Have they harmed consumers? If the answer to previous questions is in the affirmative, then what remedies should be enacted? The purpose of this paper is to address the first and perhaps the most contentious question of whether or not Microsoft is a monopoly. Although most people have a general understanding of what a monopoly is, to eliminate any ambiguity it is helpful to establish a precise definition of monopoly...

An Analysis of the Financial Status of Apple Inc. “Apple's recent success in the marketplace is founded on a philosophy that derives its insights at the intersection of technology and consumer values” (Wingfield, 2007). A prestige young owned company with its very own creative viewpoint to the way things should be done was founded by Apple Inc. in 1976. Apple has created among the most amazing technology mankind has ever known. Their three major products: Mac computers, iPod music player, and the iPhone. Database software, operating systems, and developer tools are all additional offerings Apple Inc. provides to their customers. Apple is a global product which has produced approximately 40% of sales from international operations. Rather than licensing the mac operating system to PC makers, as Microsoft did, apple chose to be the sole producer of its mac hardware, in the 1980's. Financially, Apple has grown into a large organization with profit growth each year. This company has taken its’ toll on how technology should be produced. Their financial status in the year 2010 and moving forward shows their growth in income and sales as well as Apple’s performance overall.

...a passion for technology. We take on big challenges, and pride ourselves on seeing them through. We hold ourselves accountable to our customers, shareholders, partners, and employees by honoring our commitments, providing results, and striving for the highest quality. Introduction About Microsoft Microsoft Corporation is a software company based in Redmond, Washington. Microsoft's flagship product, the Windows operating system, is the single most popular operating system for home desktop use. Its other desktop products, namely Microsoft Office, Internet Explorer, and Windows Media Player, are either bundled directly with the Windows operating system, or are often sold together with Windows as preinstalled software on new computer systems. The company also manufactures and sells computer hardware such as keyboards and mice, owns several content-distribution channels such as MSNBC, the MSN Internet portal, and the Microsoft Encarta electronic encyclopedia. The Microsoft Windows operating system was introduced as an optional addition to the MS-DOS operating system. The idea of a graphical user interface was pioneered by Apple Computer's Apple II and Macintosh. However, due to prior work with IBM, Microsoft successfully convinced the hardware giant to ship Microsoft Windows preinstalled on IBM personal computers. This step strategically had made Windows to be one of the most recognized...

...must be allowed to redistribute modified versions under the same terms/licensing, and you can not restrict people from redistributing/modifying/using the software. 4. GNU stands for "GNU'S Not Unix", and it was designed to be a UNIX-like operating system developed by Richard Stallman. Linux is the name of operating system kernel developed by Linus Torvalds. GNU's tools aside the Linux kernel make the operating system known as “Linux” aka “GNU/Linux”. Thousands, possibly hundreds of thousands, of people helped refine the operating system because it was distributed freely online. Chapter 2 # 1 1. Installing Fedora/RHEL uses the process of copying operating system files from a CD, DVD, or USB flash drive to the hard disk on a system and setting up configuration files so Linux runs properly on the hardware. Several types of installations are possible including fresh installations, upgrades from older releases of Fedora, and dual-boot. Chapter 3 #1, 4, 8 1. A live system gives you a chance to preview Fedora without installing it. It does not write/install to hard disks. 4. Put /boot at the beginning of the drive (partition 1) so that there is no issue of Linux having to boot from a partition too far into the drive. 8. When the system enters runlevel 5 Chapter 11 #1, 3, 7 1. In single user mode, only the console user may be logged in, though the user can edit files and execute multiple programs simultaneously.

...Four Types of Distributed Computer System Failures This paper will discuss four common types of distributed computer system failures which are Crash failures also known as operating system failures, Hardware Failures, Omission Failures and Byzantine Failures. Included in the discussion are failures which can also occur in a centralized computer system, and how to isolate and repair two types of failures. Crash failures are normally associated with a server fault in a typical distributed system. Inherently crash failures are interrupt operations of the server and can halt operation for a considerable time (Projects Helper, 2012).Operating system failures are the best examples for this scenario. Operating System or software failures come in many more varieties than hardware failures. Software bugs in distributed systems can be difficult to replicate and, consequently, repair and or debug. Corresponding fault tolerant systems are developed and employed with respect to these affects. An operating system or software failure can also occur in a centralized system such as a data base this is why it is highly recommended to back up a data base using stable mass storage media (Projects Helper, 2012). We have an extensive data base on our server at my work place. The storage back-up is run daily. I cannot imagine the man-hours it would take to re-input even a month’s worth of production data if it were lost due to a failure the system could not recover from. Hardware failures can...

...The User Domain defines the people who access an organization’s information system. One of the roles and tasks is that the user can access systems, applications, and data depending upon their defined access rights. Inside the User domain is where the user would find the acceptable user policy or AUP. The AUP defines what users are allowed to do within the organization-owned IT assets. The User Domain is considered the weakest and most affected domain. One reason why is that it has a lack of user awareness. Another reason is that when users are downloading various content and different files, they generally do not conform to the established security guidelines. To protect from these issues, there should be enabled content filtering as well as automatic antivirus scans. A way to protect from an user doing Employee blackmail or extortion is to enable intrusion detection system/intrusion prevention system (IDS/IPS) monitoring. The monitoring will examine the IP data streams for inbound and outbound traffic. A second domain that is affected is the Workstation Domain. The Workstation Domain is where most users connect to the IT infrastructure. A workstation can be a desktop computer, laptop or any device that connects to the network. A role of the workstation domain is that the organization’s staff should have the access necessary to be productive. Some tasks included are configuring hardware, hardening systems, and verifying antivirus files. Threats that are included in the Workstation...

...--------------------------------------------------------------------------------------------------------------------- 1. During the install, the option to sync with a NTP (Network Time Protocol) server was checked. From a security perspective, why is it important for a system to keep accurate time? The most interesting importance of NTP would be the auto key system, if your system doesn’t keep correct time a attacker who needs to change time so that a replay attack can happen could be very damaging, that is why today’s version of NTP shields against this in several ways. 2. During the install, a password has been set for the “root” user, and when is it appropriate to use this account? It is highly recommended that you only use this account when there are tasks that require root privileges such as moving files or directories into or out of system directories. 3. During the install, X-Window and a Desktop Manager were installed. However, in a production environment it is recommended NOT to run the X-Windows Environment. Explain the purpose for this recommendation? In a production environment hardware requirements and not to run the X-Windows Environment may sometimes vary, X-Window is intended for primarily workstation use only example personal computing on a Linux box. The X-Window was intended and developed for the network GUI only, X-Windows by itself doesn’t even have an interface. 4. During the install process it asks what the options given to create the partition...
