In developing Windows Server 2008, three key aspects of security were imperative in achieving goal to create our most secure operating system to date .These new security features provide unprecedented levels of protection for a company's network, data, and business, making Windows Server 2008 the most secure Windows Server ever..

As basic users, security is one feature that most of us overlook when it comes to operating systems until it is too late. In this paper we will discuss the security flaws within the Windows Operating system, and then discuss countermeasures to fix the system flaw.

When installing any operating system regardless of whether it is a Linux or windows based operating system it is essential that steps are taken to ensure the security of the operating systems. Ensuring the security of an installed operating system before for it is put into use is known as system hardening. System hardening is done by taking known vulnerabilities in an operating system and making security enhancement to mitigate these vulnerabilities. Thus, it is important to know the vulnerabilities which are posed by each operating system and the ways in which they can be mitigate. Below are three common vulnerabilities in windows operating system and recommendations on how to mitigate them.

As such, he introduces a technique of identifying a spectrum of potential vulnerabilities and suggests procedures to deal with them. Systems Specification and High Order Language Implementation are categorized as items of high risk to attacks. Security Policy and Machine Language Implementation are classified as items of moderate risk of being vulnerable to attacks. Circuits Electronics and Device Physics are of low and very low risks respectively. He also discusses potential threats such as deceiving operating systems to grant access to file or data to unauthorized users through direct (overt) and indirect (convert) channels. Walker also says that lack of precise definition of trusted operating systems and the higher cost of building them are the significant drawbacks faced by the vendors. Vendors are concerned that if they build trusted operating systems, they might not be accepted by their customers. The only solution suggested by the author was to have someone or a company builds it, shares the technology used, and convinces the general public on the significance of it. Once it becomes accepted, then there will be a widespread use of trusted computer operating systems.

The article, which addresses security loopholes in modern computing environments, by Loscocco et al highlights what is and has been being done security wise in the past and how secure these implementations were and going forward what should be done to ensure in depth security which guarantees system wide security (1998). The article first explains features of secure operating system and why current systems implemented under the notion of application space security ultimately failed to safe guard the integrity and confidentiality of our assets. The article then continued with general examples of access control and cryptography implemented in the application space with no or little support from operating system and showed their vulnerabilities to attacks such as tampering, bypassing and spoofing. The article supplied real-life examples to support the evidence that building security in the application space without secure operating system is meaningless. The article raised concrete examples on mobile code security, Kerberos network authentication service, IPSEC and SSL network security protocols and firewall. The paper finally put an interesting remark that security implemented in application space without secure operating system is like “building a house in a pile of sand” and it also emphasized that secure operating system without better security on the

3. On September 10, purchased 9,100 shares of Thep Co.'s preferred stock at $34.45 per share plus commission $6,383.

In terms of Windows operating system, which is used by ninety five percent of Costco’s data center systems, the most lethal form of attacks are at the kernel level. The significant vulnerabilities and the associated risks are: not defining the security requirements based on the stored information, provided applications and services, and the purpose of the operating system; no clearly defined guidelines for user categories, privileges, and information access restrictions; user authentication problems; information management weaknesses; weak management of other files and resources stored on connected hosts, such as database servers; loosely defined administrative privileges; and finally the risks related to the vulnerabilities in the security mechanisms, such as anti-virus, firewalls, and logging (Scarfone, Jansen, & Tracy,

My first critical thinking will be discussing and analyzing windows system and secure access control. In addition, I will be pretending that I am a manager in a big international organization and my duty is to assess the organization’s information systems and security controls. In the first part, I will be giving full definitions for the three following terminology which are identification, authentication, and authorization. In the second part, I will be searching whether or not I would use Windows ACLs and explain reasons. In the third part, I will be evaluating and choosing preferable practices for managing Microsoft Windows and application vulnerabilities. In the last part, I will be mentioning my point of view and will be finishing my

This paper was prepared for Network and Security Systems, CISK 445, taught by Dr. Marco A. Villarreal

4. Which among the following is the best reason to define security groups while configuring access

These complications have warranted an evaluation of the system and network security methods to determine existing vulnerabilities. The top five threats for the server, workstations, and website are listed below. A discussion of the likelihood of these vulnerabilities being exploited and the recommended controls and countermeasures which should be used to mitigate these threats will follow.

There are vulnerabilities that exist across every systems and applications no matter how advanced you think they are. These vulnerabilities create easy ways for cyber attackers to gain access to your environment and exploit it. This means maintaining and updating system operating systems and applications to minimizing our vulnerabilities. My Term Paper will look at some of these risks to the applications and systems across my organizations environment, and how we can prevent some of these risks. When it comes to sensitive personal and customer information you can never be too safe.

This report will look at various access control methods used by Operating Systems (OS) to control user access to files on a computer and what they can do once they have gained access. In this first section I will look at methods such as Access Control Lists(ACL’s), Capabilities and Encrypting file systems(EFS) and which Operating Systems use these as well as the advantages and disadvantages they have over each other. The second part of my report will focus on one OS and explain in detail the methods it uses to control file access and how it works.

The foundation of open systems theory is that all the components of an organization are inter-related, thus, changing one variable impacts many other components of the organization. Additionally, organizations use external and internal inputs to produce outputs. (McShane & Steen, 2009).
