Protecting Operating Systems: Access Matrix, Language-Based, and Authentication
Abstract
Operating system refers to the computer applications vital in the operations and management of the software and hardware computer programs. There is a great increase in the need for protection with the aim of enhancing the integrity of the computer systems because of sophisticated and pervasive applications in the modern society. The main objective for protection of the operating system is to prevent mischief, intentional, and violating access in relation to restriction by users. This research exercise will focus on the utilization of the advantages and disadvantages of access matrix, language-based protection, and user authentication as protective mechanisms of the operating system

Icloud and Ios 6 Integration-
After having recently upgraded the family iPad2 to the Apple iOS6 operating system, the many new features that make integration to the iCloud needed to be configured across all family iPhones and the MacBook Air our family shares. Our family went to the local Apple Store and the Genius Bar there to have a member of the staff assist us in solving account conflicts as well. The picture to the left was taken in our local store.
Visiting the Apple Genius Bar in a Local Apple Store
As our family is entirely running Apple iPhones, iPads and MacBook Air PCs, we chose to visit the Genius Bar and determine how best to make the devices work together better. There had been conflicts across each specific account, with logins often being required for various application updates on certain family members' iPhones and not on others. Each device had been updated with iOS 6. The iCloud feature had kept all the data in the right accounts and even backed up everyone's iPhone, the family iPad2 and MacBook Air, all without any of the family specifically forcing it to. The staff at the Genius Bar explained that this is how the new operating system is configured, and that irrespective of authentication to get into the Apps Store the specific accounts for each device were still recognized by iCloud and used to back up each device. As our family routinely uses these devices for homework and outside projects, that was a welcome relief. The account authentication issue had been caused by the primary account owner's ID being the default login on all devices. The expert at the Genius Bar was able to solve the problem within five minutes and had it replicate across all the devices immediately on the store's Wi-Fi system.
The Genius Bar expert also showed how each iPad in the family is backed up and how the iCloud can be configured to store all e-mail archives as well. This was extremely useful for my parents, who run a business and need to have constant back-ups of all their correspondence.
