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 anyone can appear competent and experienced in the position. The catch, however, is that if an unexpected circumstance arises that the software manufacturers did not foresee, the system will not automatically make the changes necessary to continue functioning. This is when the difference between a real...
Simply put, if the current system administrator is unable to adapt to using Unix or not able to comprehend the Unix system, then it would be in the best interest of an employer to replace this person because, even if the company stayed with the non-Unix environment, the incompetence of this employee would eventually do harm.
When changing to a Unix platform, it will be necessary to replace at least some of the application software. Some application software that is used for standardized and simple server tasks can be taken from the old system onto the new one, if the software will run on the new platform and is stable and reliable enough to continue using. The more simple server tasks can either utilize software from the old server, or new software that is easy and inexpensive to locate. One example is the Apache web server, which runs the cast majority of web sites on both Unix and non-Unix platforms. (Wheeler) Some proprietary software, which is often used by servers, may not be able
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
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
Storage management, creating and maintaining a file system, and integrating them into networks also share a common set of functions that allow for programmer flexibility in terms of their use and sequencing through an application. These functions are specifically called as part of the kernel of the Linux operating system, and as a result they can be selectively updated very quickly. A full recompile of the entire operating system
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
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
Linux Security Technologies The continued popularity and rapid growth of open source software in general and the Linux operating system specifically are having a disruptive impact on proprietary software. The disruptive impacts of open source software are so pervasive that they are completely re-ordering the enterprise system strategies in many corporations globally today (Rooney, 2004). With this proliferation of open source software and the foundation being laid by the Linux operating
