It is a key objective that for an enterprise to operate efficiently, its accessibility should be unlimited and this is when remote access is introduced. As the volume of enterprise information and data is increasing exponentially, it is an expectation that this data is easily accessed and shared among each other. To enable this, smarter network access called Remote access was introduced to deliver various degrees of data efficiently through mobile devices, applications and machines in order to stimulate productivity. There are three main types of remote access, namely Basic, Advances and Enterprise. In this paper, we will focus on Enterprise Remote access. Some of the advantages of Enterprise Remote access are; Increased high availability required for different and high volume application Remote access maintains and controls the high usage of the network. It also consistently...

...involves authenticating users with a high level of protocol and promoting accountability within the information infrastructure. This approach may involve use of the organization assets, identification, authentication, authorization and the use of third party security systems or devices to protect data from unauthorized access. Security Authentication Process The security authentication process is the first step in information security and assurance. This process involves “binding a specific ID to a specific computer connection” (University of Phoenix, 2011) in order to authenticate access to the information system. During this process the user provides a user ID and password to the computer system or remote server to verify his or her identity. Authentication is accomplished when the system or server matches the user ID to a specific password and grants the user remote access to system resources. Identification The identification process is an access control element designed to match a user to a specific process. The identification process is performed the first time a user ID is issued to a specific user. User IDs have unique values and can only be mapped to one and only one particular individual. User identification works together with authentication and authorization to form a foundation for accountability. This process allows you to trace the activities of individual users or processes in the event of unauthorized access. Authentication The process...

...Computers, networks, and software are the heart and soul of the IT world today. Because of the availability of those systems, they are very vulnerable to malicious attacks and activity. It is of upmost importance that an organization takes security seriously and takes the proper measures to protect their systems. They can do this through a number of different ways, but one area of focus is through the authentication process and the related hardware and software to go along with it. Identification and Authentication Authentication is the process of the system or program recognizing the user and granting them access, which has been predetermined by access controls. It begins with two major parts; Identification and Authentication. Identification is the process in which the system recognizes the user and gives them access according to Abstract object that are controlled by the administrators of the files and systems. Privileges will be granted based on their user account having been verified. This process is usually a user ID. The system recognized the ID and knows the access right and privileges of that individual that have been verified. The Authentication begins once the user account ID has been identified. This is the process in which the user credentials are actually verified, meaning the specific attributes of their specific user account and authenticated and verified to make sure the access rights are correct. This process uses a password or some sort of credential such...

...Information Authentication is a very common aspect of today's technology world. Anyone that uses a computer or mobile device has most likely used some form of it when logging into school accounts, shopping online, using social media, or accessing systems at work. What most individuals do not realize is that there are differing forms of authentication and ways it is used. Additionally, most people will not have any idea what is going on behind the scenes during authentication. He or she only knows that a login ID and password are required to gain access to the system. What is Authentication? The authentication process and other considerations affect the entire design and development for information systems. This and other preventative measures are used for securing data over a variety of systems. In order to learn about the authentication process, first it must be understood what security authentication is. The commonly accepted definition of security authentication is, according to “The business Of Authentication” (n.d.) “…the process of determining if a user or identity is who they claim to be. Authentication is accomplished using something the user knows (e.g. password), something the user has (e.g. security token) or something of the user (e.g. biometric) (para. 1). The important terms here are something the user has and something the user knows. In early authentication processes like automated teller machines (ATM), this idea was used by giving the user a card with...

...Security Authentication Process CMGT/400 February 9, 2013 Anthony Seymour Security Authentication Process Like most people who are computer users, you do not simply turn on your computer and start accessing programs. There are systems put in place by the user, or the administrator of the network to ensure that the properly authorized people gain access to their information. Specific profiles are created to differentiate amongst the users that allow each unique user to create, delete, and print or any other process they have access to. The process needs to be thoroughly planned out, and there also has to be a determination how whether it will be managed locally, or by third party software. This management of access controls actually comes in four different steps. The steps are: Identification, Authentication, Authorization, and finally, Accountability. No administrator worth his salt will incorporate any sort of security authentication process without these four basic steps. A properly configure authentication process will protect your network from such threats as password cracking tools, brute force attacks, the abuse of system rights and outright impersonation of authenticated users. Identification is the first of the four steps of the security process. Anyone that wishes to gain access to a system is referred to as a supplicant, and the tool that they use to gain entry to the system is referred to as an Identifier. This identifier can be a myriad of different references...

...each branch office, since each office uses data, audio, video and graphic files that are shared by staff at each location. The SAN may incorporate NAS devices which we have evaluated with different vendors. As we conducted a further research in order to provide you with more detail specifications on SAN and NAS solutions, we were able to come up with the following information design in a form of questions and answers. What is required to implement a SAN and /or NAS? Storage-area networks (SANs) are composed of computers and remote storage devices. The computers are typically connected to the remote storage devices using SCSI over Fibre Channel (see Figure 1). Other implementations of SAN exist, but this is the most common. In a SAN, all the storage appears local, just as if the remote disk were directly connected to the computer and physically located inside the computer chassis. Network-attached storage (NAS) devices appear to the user as a remote drive letter or are named remote storage device. Typically, the operating system employs a protocol such as Network File System (NFS) or Common Internet File System (CIFS) to discover, log in, and transfer content to and from a storage device. NFS and CIFS both communicate over Ethernet. The user typically enters a username and password, and then is granted access to a particular device. Figure 1. SAN and NAS use different protocols and transports. Click here to see an enlarged diagram. Read more: http://broadcastengineering....
