UNIX Marketability Requirements
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 Resource Planning (ERP) integration, transaction management and databases management and administration (de Brulin, Bos, Bal, 2011). Where the highest growth opportunities are however for those with UNIX programming and software development skills is in the area Web application development and the creation of mobile applications for the Google Android operating system and Apple iOS operating system. Of these two, UNIX has had a far greater influence on the development and continual fine-turning of Android, as Google seeking to bring this operating system to tablets, smartphones and mini-tablets in the 2012 -- 2013 timeframes (Sen, Singh, Borle, 2012). For those more interested in the administration and management of enterprise systems, there's also the role of system administrator, which can over time become a career path to system manager and eventually IT Director of Infrastructure (Dobb, 2011). This analysis will evaluate the current state of UNIX and job marketability, specifically focusing on how Linux, Google Android and Apple iOS operating system development is one of the fastest growing areas of programming employment right now. These three areas, Linux, Android and Apple iOS, are also heavily based on the fundamental concepts of UNIX, as the creators of these applications are more focused on how to create scalable, secure and stable operating systems that will lead to mass adoption of the applications built on them.
UNIX and Job Marketability Career Paths
As the majority of enterprises today run on UNIX, the majority of jobs for those with UNIX administration and programming skills are in larger enterprise running distributed applications, the majority of the time in conjunction with complex enterprise-wise databases as well (MacInnis, 2006). Current UNIX skills that are the most marketable in these larger enterprises, who often have hundreds of millions of dollars invested in their enterprise systems, include SQL query and oracle database administration and management (de Brulin, Bos, Bal, 2011). Additional skills include the need for managing complex data structures and the ability to code and create them quickly, while also aligning data structures to business problems in these larger enterprises. The role of the UNIX developer in Fortune 1,000 companies (they are the largest companies listed annually in Fortune Magazine's list of top one thousand corporations) also require intensive levels of training with analytics, accounting and financial reporting application expertise to the data warehouse and data table levels (MacInnis, 2006). These skill sets are critical for UNIX developers in enterprises as they will often also have to create very specific transaction processing and order management systems and queues to streamline the integration between legacy, 3rd party and very large-scale enterprise systems (Dobb, 2011). In this regard the UNIX developer also acts as a system architecture, ensuring the overall complex of systems in an enterprise can integrate with each other in real-time while also giving the business units the agility and flexibility to accomplish their line-of-business goals and initiatives (de Brulin, Bos, Bal, 2011). UNIX developers are expected to have a high level of expertise in shell scripting including Korn and PERL scripting languages, with Python, the scripting language Google invented, also...
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
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
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
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. Because of a pre-existing anti-trust suit, AT&T -- the parent company of
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
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
