The Operating System (OS) is the heart of computer server and client systems; therefore they are the pivotal components of the Information Technology (IT) architecture. The OS contains the crucial data, information, and applications, which are vulnerable, and can be infiltrated to cripple the entire IT architecture of the organization. Therefore, it becomes mandatory to properly safeguard the OS from an internal or external intrusion (Stallings & Brown, 2012). This critical thinking report will highlight the security concerns that may impact the OS. Further, the security guidelines and best practices for the OS in general, along with the specific fundamentals regarding the Windows and Linux OS are comprehensively illustrated.

When people think of scientists, creativity is not always the first thing that comes to mind. Scientists are viewed as quite the opposite in fact, relying on cold, hard facts, rather than having the mind to create a colorful, bright work of art. However, nothing could be further from the truth. Scientists employ a great degree of creativity when drawing diagrams of observations, thinking of new ideas, and interpreting data in unique ways. Of course, all of the above is limited by the facts, for example you can’t just draw three extra legs on an animal because you want to be creative. However not all scientist’s drawings are going to look exactly alike because everybody is a different person. No two scientific papers are going to be the exact same either, in fact they could in fact be near complete opposites, depending on how one scientist

Hello, I am Ida Tarbell. I was an American journalist who was born on November 5, 1857, in Erie County, Pennsylvania. I graduated from Titusville High school in 1875 and I attended Allegheny College in 1880 where I was the only woman in my graduating class. The region where I was born was rich with oil. My father was an oil producer. He was negatively affected by the price-fixing scheme of 1872. This scheme was made by the Pennsylvania Railroad and John D. Rockefeller’s Standard Oil Company. The small producers, like my father were forced to sell the oil he produced to Standard Oil. My father was one of the few people who chose not to do this and he struggled because of this. I accepted a teaching job in Poland, Ohio, but I walked away from
Nowadays, most of the web, email, database and fileservers are Linux servers. Linux is a UNIX system which implies that it has solid compatibility, stability and security features. Linux is used for the mentioned environments because these services require high security. Further, an increase of attacks on these servers can be observed. Additionally, the methods to prevent intrusions on Linux machines are insufficient. Further, the analysis of incidents on Linux systems are not considered appropriately (Choi, Savoldi, Gubian, Lee, & Lee, 2008). It can also be observed that a lot of investigators do not have experience with Linux forensics (Altheide, 2004).
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
In fact, according to several studies, more than half of all network attacks are committed internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, and root access attacks.... ... middle of paper ... ...
As the internet is becoming faster and faster, an operating system (OS) is needed to manage the data in computers. An Operating system can be considered to be a set of programed codes that are created to control hardware such as computers. In 1985 Windows was established as an operating system and a year earlier Mac OS was established, and they have dominated the market of the computer programs since that time. Although, many companies have provided other operating systems, most users still prefer Mac as the most secured system and windows as it provides more multiple functions. This essay will demonstrate the differences between windows
While there are literally hundreds of new features in this operating system, too many in fact to list in a paper of this scope, it is useful to look at the key differentiators, or what makes this operating system highly unique that are its core technologies and those enhancements focused on security.
