Authentication, ization and accounting (AAA) server By Authentication, ization and accounting server helps to harmonize QoE across technologies and networks as well as consolidating the authentication. Enterprises and service providers also benefit from lower TCO, simplified management and fast time to market. It is in enforcing policies, auditing usage, controlling access to computer resources and providing information necessary to bill for the services. The combined resources are considered essential for effective network security and management. One of the benefits of the servers is to enhance security (Lin, Cheng & Liao, 2009).
Authentication is suitable for user identification, typically by having the user enter a valid password and username before access is . The authentication process enables each user to have unique criteria for gaining access to the computer. The AAA compares other user credentials within the database to the authentication credentials. The user is only granted access when the credentials match with one another. Authentication fails when the credentials are at variance, and the access is (Choi, Jung & Jang, 2007).
After authentication, a user has to be authorized (authorization) to perform a certain task. The user may try to issue the command after logging into the system. Authorization is the process of determining the qualities or the types of resources, activities and services that a user is permitted to undertake. Accounting measures the resources that a user utilizes during access. It comprises the amount of data and time that a user has spends or used (Lopez-Fernandez et al., 2014). Bu is using the server the company can control access to information and data while at the same time keep record of the time and resources spent by the user.
The motive authentication, authorization and accounting server addresses roaming partnerships, complex resource sharing and integration of disparate technologies such as Wi-Fi, LTE, DSL, GPON and small cell. The server delivers extended functionality for the deployment of blended multimedia services, wireless LANs and other networks supporting fixed mobile roaming. The server is beneficial to the organization since it supports unlimited numbers of subscribers having many configurations (Zaghloul & Jukan, 2009).

... Server: Error Monitoring in SQL Server Error monitoring in a database management environment is vital for ensuring consistency in the data. The standard approach used to perform this task is reviewing error logs. However, as the volume of logs increases, it becomes challenging to a Database Administrator. As such, this paper will discuss how to monitor and capture errors in SQL Server using event notification and extended event. Event notification has an ERRORLOG event, which ensures that messages sent to the error log are also sent to the service broker queue for automatic processing. Figure 1 is a sample script for setting up an ERRORLOG event in SQL Server. However, a stored procedure must be added to the service broker queue... to...
