Throughout this course you will be working on several aspects of operating systems security that will result in a complete Operating Systems Security Policies document for an organization of your choosing. Operating systems security is vital to the operation of the computer systems infrastructure in any organization and provides the protection of valuable data and information. Each week, you will complete a part of the Operating Systems Security Policies document, with the final draft due at the end of the course.
You will select an organization and apply your research to the analysis and development of operating systems security policies that would be appropriate for the organization and the needs it has for its systems. Additional information and the deliverables for each Individual Project will be provided in the assignment description for the project. This is the course Key Assignment that you will make contributions to each week.
The first step will be to select an organization as the target for your Operating Systems Security Policies document. This organization will be used as the basis for each of the assignments throughout the course and should conform to the following guidelines:
Nontrivial: The selected organization should be large enough to allow reasonable exercise of the operating systems security analysis process.
Domain knowledge: You should be familiar enough with the organization to allow focus on the project tasks without significant time required for domain education.
Accessibility: You should have good access to the people and other information related to the organization because this will be an important part of the process.
Note: The selected organization may already have operating systems security policies in place and may still be used as the basis for the projects in this course.
Note: The selected organization must have a need for some type of operating systems security as part of its operations. Therefore, you may feel free to identify a hypothetical organization that meets the requirements. Any necessary assumptions may be made by you to fulfill the requirements of organization selection.
Select an existing organization or identify a hypothetical organization that fits these requirements, and submit your proposal to your instructor before proceeding further with the assignments in the course. Approval should be sought within the first several days of the course. Your instructor will tell you how to submit this proposal and what notification will be given for project approval.
For the assignments in this course, you will not be implementing an operating systems security policy; rather, you will be developing a comprehensive operating systems security policies document. Your first task in this process will be to select an organization or identify a hypothetical organization to use as the basis of your projects. You will also create the shell document for the final project deliverable that you will be working on during each unit. As you proceed through each project phase, you will add contents to each section of the final document to gradually complete the final project delivery. Appropriate research should be conducted to support the development of your document, and assumptions may be made when necessary.
The following are the project deliverables:
Submit the organization proposal to your instructor for approval.

Security Threat Detection
Project Outline and Requirements
Give a brief description of the organization (can be hypothetical) where the operating systems security policies will be implemented. Include company size, location(s), and other pertinent information.
Identify the systems in the organization (i.e., the type and number of computer systems and operating systems used, along with a top-level view of the infrastructure). A network diagram would be useful for this purpose, but the diagram should be pasted into your Word document.
Your project must assume that the organization has UNIX, open source, and Windows operating systems in its computing environment, so be sure to include all 3 categories in the systems overview.
Identify and describe any outside connections to the internal systems.
Summarize the benefits the company would realize through the implementation of operating systems security policies.
Material can be taken from the approved proposal submitted to the instructor.
Be sure that this project is approved by the instructor.
Operating System Security Tools
Based on the systems overview, identify and describe at least 3 security tools for each OS category (UNIX, open source, and Windows) that can be used at the operating system level to protect the systems, users, and data from security threats.
The tools can be part of the OS or third-party tools. Some examples would include firewalls, account management, and port access management.
, a multiple-access operating system that implements IBM virtualization technology, is the successor to IBM's VM/ESA operating system. z/VM can support multiple guest operating systems (there may be version, architecture, or other constraints), such as Linux, OS/390, TPF, VSE/ESA, z/OS, and z/VM itself. z/VM includes comprehensive system management API's for managing virtual images.

Other server families, such as the iSeries, and other IBM operating systems, such as OS/400, also support logical partitioning. There is a primary OS/400 partition, that loads a hypervisor (known as "the Hypervisor"), which provides partition control, mediation, and isolation. You can then have further OS/400 partitions, as well as Linux partitions.
IBM's Logical Partitioning (LPAR) allows you to run multiple, independent operating system images of AIX and Linux on a single server (that supports such partitioning, such as the pSeries family). The minimum resources needed for a pSeries partition are: one processor, 256 MB memory, an I/O slot and its attached devices. The AIX Workload Manager (WLM) is used for resource management.

Microsoft, and many enterprise software vendors, have also been making their applications virtualized. Microsoft's SQL Server 2000 has multiple instance capability. Microsoft's Exchange Server, File/Print Servers, IIS Server, Terminal Server, etc. also don't really need virtualization support in the operating system. There are pros and cons of virtualizing within an application, but there are scenarios in which anything stronger, or lower level, is overkill, or not optimal.
Nemesis is an operating system designed at the University of Cambridge Computer Laboratory to support quality of service. The Nemesis kernel is extremely small and lightweight, and most of the operating system code executes in the application process itself. The kernel has a scheduler and some other code for low-level CPU management. There is a single global page table (a single address space), although per-process memory protection is still there. Since the kernel performs much less work on behalf of an application, there is much less scope for the "wrong" process being charged for somebody else's work (often referred to as QoS crosstalk).

Cyber security involves various steps the most important of these being an individual’s understanding of the different forms of attacks that they are likely to encounter. Once one has knowledge of this, then it is his or her responsibility to ensure that they have put in place the best security system they can get their hands on. There exist different types of threats and these can be considered to be of varying levels and risks to an individual’s personal information in their computers. The higher the possibility of an attack, the more advanced the security system that is to be put in place to ensure that the threat is minimized.
Windows XP Operating System Security Analysis
Cyber security involves dealing with threats that range from malicious codes, which are known as malware and spyware, to computer viruses. Some of these viruses are so serious that they have the ability to erase entire operating systems of computers. These viruses also enable hackers to have access to all the data stored in the infected computers, ensuring that they have access to information, which can be used for personal gain.

It is, therefore, necessary for individuals to avoid such intrusion into their computer systems by having the best cyber security systems. These involve the acquisition of antivirus software that is reliable as well as frequently checking this software to ensure that they are preventing attacks. The software has to be frequently updated so that there is an assurance that it is working at its full capacity, hence additional security against attack. It is important to ensure that individuals are conscious of their cyber security because it is not known when a threat is likely to be encountered.
What is Operating system security?
In order to define UNIX, it helps to look at its history. In 1969, Ken Thompson, Dennis Ritchie and others started work on what was to become UNIX on a "little-used PDP-7 in a corner" at AT&T Bell Labs. For ten years, the development of UNIX proceeded at AT&T in numbered versions. V4 (1974) was re-written in C -- a major milestone for the operating system's portability among different systems. V6 (1975) was the first to become available outside Bell Labs -- it became the basis of the first version of UNIX developed at the University of California Berkeley.
