VPN and RADIUS
The boom in telecommuting and the need to support more remote workers is making life tough for IT managers.
Besides the normal tasks of maintaining remote-access server (RAS) equipment, managers often find their time consumed administering access rights and authentication privileges on several, geographically dispersed remote access servers at the same time.
Enter the Remote Authentication Dial In User Service (RADIUS), a commonly used authentication system. Most remote-access equipment vendors have supported RADIUS in their remote-access ser-vers. Many virtual private networking equipment companies also are supporting the use of a RADIUS server for user authentication.
For IT managers, the main attraction of RADIUS is that it allows them to simplify administration of user authentication by maintaining a centralized database of access rights.
IT managers who did not have RADIUS have had to maintain access rights on multiple pieces of equipment. This leads to a problem: If someone joins or leaves a company, a manager must add or change access rights for that person on every piece of access equipment.
RADIUS avoids such problems. IT managers can use a single RADIUS server to authenticate users dialing into multiple remote-access servers. With RADIUS, IT managers maintain a single authentication database. All users dialing into a network are authenticated against this database.
For such centralized authentication to work, a RAS and VPN equipment must securely communicate with a RADIUS server and verify that the user meets certain conditions before allowing the user to gain access to the network.
The process of authenticating users is transparent to the user dialing in. The way it works is that a user places a call into a remote-access server and a Point-to-Point Protocol session is initiated. The RAS or VPN takes authentication information, such as a user name and password, and passes this information to the RADIUS server.
If the user is in the database and has access privileges to the network, the RADIUS server signals the remote-access server that it is OK to continue the process.
At the same time, the RADIUS server also sends what is called profile information about the user to the remote-access server. The profile can include information such as the user's IP address, the maximum amount of time the user can remain connected to the network and the phone number the user is allowed to dial to access the network.
The Role-Based Zoning model is proposed using the concept of SAN Zoning and Role-Based Access Control (RBAC) model. Role-Based Zoning model provides the better security, flexibility, and reduce traffic overhead.
According to Tuncay Bayrak, in his paper, IT Support Services For Telecommuting Workforce, in new era of technology, organization faced many radical changes. The changes involved from traditional workplace into more technology ways. With the existence of various types of software that enable long-distance communication, telecommuting workforce has been evolved. Nowadays, the organization was transformed to become a network-based operating structure where employees are not tied to the workplace. Every day, the rank of telecommuter job continues to grow. Telecommuting job allows employees to work from home or remote locations across the world. The question is what is the different service support that was provided by the organization for telecommuter and traditionally employee in a regular office. The aims of this study are to explain many types of support service for telecommuting employee that can be provided and the different support service that needed for telecommuters and desktop computing. The goal of this paper is to provide a framework to help IT manager to solve the issues in increase their potential benefit of providing good support service.
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
Remote-control software is an application that you install on two PCs that permits one system (the guest) to connect with and control another (the host). Once you're connected, you can do just about anything as if you were sitting at the host PC. In addition, remote-control software lets you transfer files between PCs faster and more efficiently. The latest remote-control programs support a myriad of connection types including Internet connections, which are becoming increasingly important. The key advantage to Internet connections is that they let mobile users connect to a PC or server anywhere on the globe via an inexpensive local telephone call. So no matter where you are, you can always stay in touch.

...ks) each user connects to another user, only using a server to find other users.
In conclusion, a local area network is made up of computers and a myriad of devices, such as routers, servers, switches, and firewalls. In order for it to connect to the Internet, a router must be installed. Servers provide special functions such as printing, file sharing, etc. Switches connect the computers together from different parts of the network. Firewalls prevent unauthorized access. There are a host of other devices that may be used as well. These devices are hubs, gateways, repeaters, wireless access points,
This proposal is for a small office that will have users who are connected by Wi-Fi or cable. The network will include devices and resources that is shared among all the users. The network will need to have security measures in place to protect the entire network and keep the wireless access secure and available only to employees of the company.
While technological innovations can provide increased opportunities for organizations and give them a competitive advantage, not all employees respond well to changes in their everyday workflow. When an organization updates its systems, it can face some resistance from employees, especially when the employees do not feel properly trained and lack the confidence in using the new system. Employees may grow frustrated and become less productive and efficient. In some extreme cases, technology can also replace some of their duties and make their positions obsolete, leaving them out of a job. This ties back to the need for job security. Technology has come a long way in the past 50 years and the types of challenges just mentioned are a lot more common in this day and age than they were before. Therefore, managers need to adapt to this changes in the work environment and find a way to satisfy their employees’ needs while increasing work performance and
Telecommuting may be the movement of the future, which will allow more people to work away from the office. Many people see telecommuting as a way to be close to home or allow them to be connected to their organization while working abroad. While telecommuting might work for some people, telecommuting is not for everyone. There are many disadvantages; as well advantages to telecommuting which most people do not take into account. When considering telecommuting, the advantages fall for both employer and employee. The same can be said about the disadvantages of telecommuting.
The workplace today goes beyond just the walls and ceilings that surround an office environment or office building. According to the International Telework Association and Council, 44.4 million Americans worked from home at least part of the time in 2004, up 7.5% from just on year earlier (Earthweb, 2005). Though it may be very convenient to work from home, the choice can bring its own set of problems. There are financial reasons, efficiencies, and even managing time are just a few to name that bring about many challenges and issues that any remote employee would face in that type of work environment.
Studies show that the cost of setting up a potential telecommuting situation for an employee or employees is dependent upon the existing technology level of the employer and potential telecommuting employee(s), the type of security network required to safeguard the data transmitted between them and the size of the operation. If an employer has a preexisting computer infrastructure including base units and server capabilities it can decrease the startup costs of a telecommuting operation. For small businesses the investment could be as little...
With the rise of mobile working whereby companies employ from different regions without necessarily having employees enclosed in one building, they end up employing more skilled and qualified workers regardless of their location. This has been made possible by companies embracing virtual meetings and video conferencing where managers and

Database management systems also allow a business to be more secure. The database administrator can create the user permissions, which allows each employee access to different things. This is usually done by assigning different usernames and passwords. It can prevent employees from viewing certain documents that are meant only for cooperate, or preventing them from accidentally deleting
