ile Management Paper
For proper security and for the right groups or individuals to access certain files, permission has to be granted to a group or the individual user for UNIX or any other operating system to keep things secure. In order for any system to give permission to a user for access rights into a file, there has to be some kind of secure log-in to be placed on the file. Usually the file that has to be secure is set up by the owner of the data. In UNIX, the security is set up by using something called an ACL or Access Control List. The ACL gives a level of security that allows groups or individuals to access the files that you want to share with them. Classic UNIX security provides for two areas of security when it comes to file sharing. The two areas are read and write. However, if administrator wants to give certain individuals a read write security level and others just read security, the administrator will have to use the ACL because classic UNIX security does not allow this to happen.
Concerning an ACL there are several typical scenarios that make sense. The ACL will help to provide access to the file for a user that is not the owner or a member of the primary group for this file. The ACL will help to provide access to the file for a group other than the specified for this file group (owner-group). The ACL will help to exclude particular users who are a member of the owner-group from accessing the file or directory (Bezroukov, 2011).
ACL’s can also be configured so that the administrator can monitor who tries to access the files and folders. The administrator should monitor the systems for any unauthorized use of the setuid and setgid permissions to gain superuser privileges (Bezroukov, 2011). A suspicious listing would be one that grants ownership of a setuid or setgid program to a user other than bin or sys. In our world today security is highly coveted and especially of important data. The administrator can also check to see who has logged in. With the use of the command logins it will display the status of who has logged in. The administrator can disable a user’s login temporarily or even save the failed login attempts. Authentication is a way to restrict access to certain users. System administrators can restrict the ability to gain access to the system or even a network. Authorization after the user gets on the system makes restrictions to what they can do. There are two types of ACLs. The first is access ACLs and second is default ACLs. An access ACL is specifically an access control list for accessibility. A default ACL can be associated only with a directory. If a file within the directory does not have an access ACL it uses the rules of the default ACL for the directory (Bezroukov, 2012).
One thing is that permissions can be added or modified to a file that has already been made secure. The biggest problem of ACLs is their potential to
memory management, process management, file management, and security. In order to compare each OS, we will discuss and compare how each of the operating systems handles each of the operations. Memory Management Memory management is responsible for the monitoring, allocation, use, and management of a systems memory ("Techopedia", 2015). The effective distribution of memory allows an OS to perform at maximum performance levels. Each of the four main operating systems handle memory management functions…

but they also have some similarities too. Linux, Mac and Windows use memory management, process management, file management and security management to operate the computer systems correctly. The first management to compare and contrast between the three OS is memory management. Memory management is a process of handling computer memory to different programs to operate a system effectively. This type of management in computers involves storing physical data using RAM, chips, memory caches and virtual memory…
will provide a comparison of the following operating systems; UNIX, LINUX, MAC, and Microsoft Windows. Each section will provide details for each of the operating systems. The areas that will be reviewed include, History, Memory Management, Process Management, File management, Security, User Interface, Server Performance, Clustering, and Load Balancing. Before getting into the details of each system, brief history of each system will be provided. Platform History This section will provide a general…

systems available today and with technology growing every day and knowing what is available on the market will help you choose the right one. All these systems use several different complex algorithms of memory management and make the system run better with the available memory. Memory Management Mac® The Mac® operating system uses different types of memory; free, wired, active, and inactive, ("What Is Free, Wired, Active, And Inactive System Memory (ram)?," 2010). First of all is the free memory in…

File Access Paper Bruce Campbell University of Phoenix Introduction to Operating Systems POS/355 John Buono June 30, 2013 File Access Paper When working with UNIX file management there are two ways in which to secure your files and only allow access to the individuals that need it. Included in the base implementation of UNIX from a very early iteration is basic access control. “Each user is assigned a unique user identification number” (Stallings, 2012, p. 558), and then assigned to a…
Windows 8 POS/355 September, 16 2013 Windows 8 Windows 8 is a fast fluid operation systems that is optimized for touch screen hardware. User applications are organized into easy to touch tiles on the start menu and can be activated by a simple touch or mouse click. The tiled applications also update independently from each other on the start screen giving the user live updates in each app in a summarized view on the tiles. Windows 8 also has a full desktop tile that allows the user to switch…
