UNIX Marketability equirements
UNIX and Job Marketability, 2012
UNIX is the most-used operating system powering enterprise today, surpassing Microsoft Windows and all other operating systems combined. UNIX is also the foundation of the Linux operating systems, many variants of open source software, and is also in large part the theoretical foundation of the Google Android operating system (Sen, Singh, Borle, 2012). As a result of the pervasive adoption and widespread standardization on UNIX, the career opportunities are very significant. The salaries for positions vary by the difficult of the work being done, difficulty of replacing the person doing it, and the scope of experience a job candidate has (MacInnis, 2006). The future for those with UNIX programming and development skills is also being accelerated by the rapid adoption of Linux as the foundational operating systems of enterprises today, specifically in the areas of Enterprise esource Planning (EP) integration, transaction management and databases…...

Unix provides many more options to an administrator, and having a consultant may help decide what methods would be best for the individual circumstances; administrators making the switch from other platforms will be used to having to just make do with whatever is available rather than being able customize options for best fit.
Being the administrator of a server is a skilled task, and is not something that should be left to the vices of someone whose intelligence is suboptimal. Some software, like Windows, that is marketed to businesses attempts to make it seem like just anybody can be a system administrator. The appeal of these platforms is that the software itself will try to be the administrator and all one has to do is point, click, and use big words when speaking with other employees. These types of software will dictate policy to the user (Raymond) so that almost…...
6.30. When there are no restrictions for unprivileged users and if the option for config_rdskernel configuration is set, hackers can write arbitrary values into kernel memory (by making specific types of socket function calls) since kernel software has not authenticated that the user address is actually found in the user segment. The lack of verification of the user address can provide hackers to gain privileges and access to areas that they should not have, since they are not users with an address residing in the proper user segment.
Perhaps the most insecure facet of Unix systems can be found in the usage of r-tools, which also routinely fail to verify the authenticity of user names and addresses. In theory, r-tools are supposed to function as a measure of convenience which allows privileged users the ability to login to networks and individual computers without presenting a password. Yet this same potential allows…...

UNIX Systems have been instrumental in the information systems management of corporations and organizations for many years. Although in recent years it has been overshadowed by other operating systems, it still remains as an alternative to other systems. The purpose of this discussion is to describe the benefits and problems associated with UNIX systems.
The most beneficial aspects of UNIX are the robust nature of the system and the ability to secure the system effectively. The robust nature of the system allows organizations to manage various technological functions properly with speed and ease. The ability to secure the system allows organizations to tightly control who can access the system.
Two of the most problematic aspects of UNIX have been the differences in the versions of UNIX that were offered by various vendors and the fact that the system has not been as user friendly as other alternatives. The differences in the versions…...

Write programs that handle text streams, because that is a universal interface.'
This philosophy evolved to fully permeate every part of the programming industry. Furthermore, the philosophy of using text streams further improved Unix's universality.
In the mid-70s the cat got out of the bag. Unix spread through the academic world like wildfire and soon into the corporate world. ecause of a pre-existing anti-trust suit, AT&T -- the parent company of ell Labs -- was prevented from marketing Unix as a product, this led to its rise as a free, or open-source software. The upshot was not only the widespread dissemination of Unix, but also the development of tools and code for it in a competitive environment, leading to exponential improvements in short periods of time.
The problem came in the mid-80s, when the multiplicity of Unices fostered a well-meaning, if misguided, standardization attempt. AT&T, in partnership with Sun Microsystems, initiated the…...

The Windows operating system architecture also allows for single sign-on and also relies on user name and password verification. The authentication process for a Windows operating system at the server level can also be configured to validate the identity of the person logging in at the Windows domain and Microsoft Active Directory Service levels as well. Certificates can be assigned to specific applications, databases and processes within a Windows sever-based architecture and operating system configuration (Vellalacheruvu, Kumar, 2011).
Another significant difference between UNIX and Windows security is the definition of the security model itself. UNIX defines permissions to the file level using user name and password, and can also assign security levels of a given process as well (Takeuchi, Nakayama, 2006). In many UNIX operating system versions a UID and GID-based session will be started when a user logs in and attempts a specific application or system-level process. It is possible…...

Linux Security Strategies
Comparing Linux Security Applications
The pervasive adoption of the Linux operating system has led to a proliferation of new security tools and applications for ensuring the security of systems and applications. The intent of this analysis is to evaluate chroot jail, iptables and SELinux. These three security technologies are evaluated from the standpoint of which organizations were behind their development, in addition to an explanation of how each technology changes the Linux operating system to make it more secure. Finally the types of threats that each of the technologies is designed to eliminate is also discussed.
Analysis of chroot jail
The chroot jail command was developed and first introduced during the initial development of the Unix Version 7 operating system in 1979 to ensure that users of UNIX-based workstations could still navigate to the highest levels of directories on their systems. The Berkeley System Division (BSD) versions of UNIX were very…...

Windows, UNIX, Linux Servers
In computing, a server provides the necessary support for the functioning of all a user's various applications, including but not limited to "email, web and even database hosting" (Edmund 2014). Some of the most common servers are UNIX, Linux, and of course Microsoft. Because of Microsoft's ubiquity, it is often the default server that most organizations and private individuals choose. However, this is not necessarily the optimal system for all computing needs. Given the challenges of switching servers once one is selected, it is essential to select the best one for the organization or individual at the outset.
Microsoft's Windows server provides support and updates in a hassle-free…...

, Minoves, Garrigos, 2011). UNIX and Linux are considered the best possible operating system for managing the development of unified collaboration and workflow-based applications as a result (West, Dedrick, 2006).
For all the advantages of UNIX and Linux, the disadvantages include a development and administrator environment that is archaic and command-driven, lacking much of the usability enhancements that Apple and Microsoft both have invested heavily in. The UNIX and Linux user command lines are more adept at managing the specific features and commands at the operating system level, and often must be coordinated in a shells script to accomplish complex tasks. This has led to many utilities and add-on applications being created, which tends to confuse the novice just getting started on the UNIX and Linux operating systems. The learning curve for UNIX and Linux from a user standpoint is quite high and takes months to master at the system command…...

Cyber warfare, a term defined by Clarke (2010) as an action of a nation-state to effectively penetrate another nation's computer resources or networks for the sole purpose of causing malicious damage or even disruption is a major cause of national and global security concerns (p.6).In this paper, we identify some cyber warfare tools (either Attack, Defense, Exploitation), and write a scenario to execute the tools. We also identify if the tool is for UNIX or Windows hacks, outer Attacks, etc. Also identified is why you would want to use the tool as opposed to another tool which may conduct the same form, via comparison and contrast.

Inhibitors to adopting (installing or upgrading) Linux (such as RedHat or SuSE) or UNIX (AIX, HP-UX, Solaris) in a Desktop-Workstation environment
Unix-like operating systems have been the top choice for use on servers for decades, but were generally considered unsuitable for end-user desktops until recently. Starting in the late 1990s, Unix-like systems, especially Linux have made significant inroads in the Windows-dominated desktop market. UNIX provides many advantages, however there are significant obstacles to deploying it in a desktop environment. The fact that most employees within an organization not already using Unix desktops have probably never used Unix may be the most obvious obstacle. Users can usually be retrained, though this does present some difficulties. In addition to the end users, system administrators must also be retrained to support and maintain Unix workstations. Most organizations use Windows on their desktop computers and are dependent on software intended for Windows. Migrating to Unix…...

Non-discretionary controls means than there is mandatory access control. In this type of system, security is enforced by a strict set of rules that creates a hierarchy of permissions that users cannot override. Essentially, this type of system is meant to hinder insider users from actually working against the system. Users cannot access crucial internal information as to become spies, thus they cannot see the internal designs of the system to stop leaks such as selling internal designs to competitors, implanting spyware or other malicious software, making critical errors that would injure the system, or access sensitive records that can be leaked to outside sources.
According to the research traditional UNIX is not non-discretionary, but rather a version of a discretionary ACL. In this, there are options as to what users have access to sensitive security information from within the system design. Unlike non-discretionary systems, typical UNIX systems categorize users into…...

Linux Feasibility
Linux started around 1991 because students were not satisfied with Minix. Linux operating system provided an affordable alternative for the expensive UNIX operating system. Because of affordability, Linux became popular, and Linux distributors were created. Linux was built with networking in mind hence provides file sharing. Linux can work with most computers because it does what it is told and works gracefully as a server or workstation.
Workstation and servers
Workstation is where individuals use for their productivity tasks and servers exchange data with others over a network. Server software includes web servers like mail servers, login, time and news servers which can often be accessed remotely. Workstation software includes spreadsheets, word processors, graphic editors, web browsers and mail readers. Different vendors focus on servers while others eye the desktop market.
