Handling user access

In this chapter, we consider the various aspects of files and the major directory structures. We also discuss the semantics of sharing files among multiple processes, users, and computers. Finally, we discuss ways to handle file protection, necessary when we have multiple users and we want to control who may access files and how files may be accessed.

In a cognitive radio network (CRN), a preempted secondary user (SU) is placed in a call level queue to wait for accessing another free channel. If the availability of channels is transparent to SUs, packets will be generated during their waiting time and the performance of the CRN will be influenced by which way to handle these packets. In this paper, the call level queue is departed into two parts, delay queue and discard queue.

Short Messaging Service (SMS) is popularly used to provide information access to people on the move. This has resulted in the growth of SMS based Question Answering (QA) services. However automatically handling SMS questions poses significant challenges due to the inherent noise in SMS questions. In this work we present an automatic FAQ-based question answering system for SMS users. We handle the noise in a SMS query by formulating the query similarity over FAQ questions as a combinatorial search problem.

The Internet creates one economy and one market. As large as the online higher education market is in the U.S., the global opportunity is significantly greater. Unlike the U.S. where post-secondary education is relatively available, access to world-class post-secondary institutions in many parts of the world is limited. Currently, there are 84 million students enrolled in higher education worldwide. Global demand for higher education is forecasted to reach 160 million by 2025 − if online learning captures even half of this growth, there would be 40 million students for online education.

Perimeter security solutions control access to critical network applications, data, and services so that only legitimate users and information can pass through the network. This access control is handled by routers and switches with access control lists (ACLs) and by dedicated firewall appliances. A firewall provides a barrier to traffic crossing a network’s “perimeter” and permits only authorized traffic to pass, according to a predefined security policy. Complementary tools, including virus scanners and content filters, also help control network perimeters.

Each function in MATLAB contains a set of variables specific to that function. Even in the same .m file, you don’t have (direct) access to variables created in other functions within the file. Global variables give you the ability to create/change a variable in one function and have that updated variable accessible elsewhere. This post will discuss two methods for handling (no pun intended) global variables, one of which is perfectly integrated into Graphical User Interfaces (GUIs).

There are many more ways to access Cisco routers than most network administrators realize. Each of these methods can have different authentication methods and can be set to allow various levels of privilege access. It is important that all methods of access are either secured or disabled.
