Remote Access Strategy Vs Direct Access Strategy: A Comparison

Functionality Of Remote Access Strategy

Discuss About The Remote Access Strategy And Direct Strategy.

Remote access is the capability to have access to all computers or systems from remote location. It helps in the accessing of network even if the person is not present in the specific part (Rhodes-Ousley, 2013). Direct access is the capability to access any physical record, which is kept in the discrete location. Both remote access and direct access strategies have their distinct functions.

The following essay will outline a brief discussion on the two important strategies of memory allocation viz. remote access business strategy and direct access strategy in terms of their response time for any particular organization. A detailed comparison between the response times of each strategy for the company is provided in the essay.

Both the Remote Access Strategy and the Direct Access Strategy have unique functionalities (Chuang & Chen, 2014). These functions extremely important as well as relevant in managing any network and memory and also any company where there is a high demand to establish connections remotely. The main functions of the remote access strategy are given below:

1. i) Provides Allowances: This is the first and the foremost function of remote access strategy (Jones et al., 2014). It helps to provide allowances for the purpose that any single operator might have administrative overview on the various disparate systems, which are taken into consideration within the information of the organization.
2. ii) Acknowledges Interruption: This is the second functionality of remote access strategy (Melkonyan et al., 2014). It explicitly acknowledges any type of interruption, prevention, hijacking or capturing of remote access through the specific activities of any party that has security controls even after the communications are operated by system owner.

Builds Connection: This is the most important and significant functionality of remote access strategy. It helps to build the connection with the virtual private network or VPN, local area network or LAN and the wide area network or WAN (Maiti, Maxwell & Kist, 2014). This type of connection helps the user to access any type of network remotely and without any type of complexity.

1. iv) Excludes Communication: The fourth functionality of remote access strategy is to exclude the communication between the network areas that are protected.
2. v) Providing Common Environment: The remote access strategy is responsible for providing common environment, where all the different sources like clients, intermediaries and even the offsite employees could access information through emails and all types of web browsers (Maiti, Kist & Maxwell, 2015). Most of the organizations supply their own specific virtual private network connections
3. vi) Includes Communications over Equipments: Remote access strategy even includes communication over various equipments where the logical and physical security is not validated explicitly (Gill, Yang & Wang, 2013).

There are various functionalities of the Direct Access strategy as well. They are given below:

1. i) Provides Intranet Connectivity: The first and the foremost functionality of direct access strategy. The Direct Access provides intranet connectivity to the client computers as long as they are being connected to the Internet connection (Oberto, 2013). It helps to connect to the computer automatically and without any type of external connections.
2. ii) Establishes IPsec tunnels: The direct access strategy establishes IPsec tunnels to the server of Direct Access from the clients and thus utilizes IPv6 for reaching to the intranet resources or all clients of Direct Access (Brisaboa, Ladra & Navarro, 2013).

There are some of the most significant and important pros and cons of remote access and direct access strategies. The various pros and cons of remote access strategy are as follows:

1. i) The first advantage is that it responds well in every emergency situation, which needs immediate access (Li et al., 2014).
2. ii) The second significant benefit of remote access is that documentation could be done anywhere.

Connections to the local area network, wide area network and virtual private network are extremely easier in comparison to all other networks (Liyanage, Ylianttila & Gurtov, 2014).

1. iv) The fourth important advantage of remote access strategy is that the systems could be easily accessed.
2. v) The fifth advantage of the remote access strategy it helps to include communications over the equipments (Li et al., 2014).

In spite of having all these advantages, remote access strategies do comprise of various disadvantages. The most significant disadvantages of a remote access strategy are as follows:

1. i) Remote Access strategies are extremely costly and cannot be afforded by all. Since, remote access is costly or expensive to implement, it is evident that remote access strategies are expensive to be used (Chung et al., 2013).
2. ii) The second disadvantage of the remote access strategies is that the information is often hacked or often is inappropriately viewed by the unauthorized users.

The third significant disadvantage of the remote access strategies is that additional security is to be provided to the network so that the information is breached (Wang et al., 2013).

Direct Access Strategies do comprise of several advantages and disadvantages. The pros and cons of the direct access strategies are given below:

1. i) The most significant advantage of the direct access strategies is that it could be easily deployed to any site (Jain & Paul, 2013).
2. ii) The second important advantage of this direct access strategy is that it helps to enable for a secured and encrypted virtual private network.

Functionality Of Direct Access Strategy

The third significant advantage of the direct access strategy is that it helps in the maintenance of a secured network (Conti, Hasani & Crispo, 2013).

The fourth important advantage of direct access strategy includes automatic connectivity to the Internet connection.

However, few disadvantages are also present in the direct access strategies. They are as follows:

1. i) The first and the foremost disadvantage of the direct access strategies is that it runs over only on IPv6 (Rhodes-Ousley, 2013).
2. ii) The next significant disadvantage of the direct access is that it is only connected to the Windows Server 2008 SP2 or Windows Server 2008 R2.

The third important demerit of the direct access is that for the connectivity or communication on the Internet, protocols are needed to be bridged (Chuang & Chen, 2014).

These above mentioned pros and cons of the remote access strategies and direct access strategies clearly depicts the entire concept of remote access and direct access strategies.

Remote Access strategy and direct access strategy: both have their respective response times. When employed in any organization that has a large number of demands to establish the remote access (Melkonyan et al., 2014). The response times of remote access strategy and direct access strategy are completely different. There are few important differences between the response times of each strategy.

The response time of direct access strategy is much less than the response time in remote access strategy. In the direct access strategy, the connection is done automatically and without any type of complexities (Maiti, Maxwell & Kist, 2014). Direct access is also known as the unified remote access strategy which is similar to the technology of VPN or virtual private network. It provides the connectivity of Intranet to the client computers, the moment they are being connected to Internet connection. There is a dedicated user interface, which helps in the management and configuration purposes (Gill, Yang & Wang, 2013). Since, the connection is done automatically in the direct access strategy; the response time in the direct access is much less than the remote access. In the remote access strategy, the scenario is different. The connection is done with the help of a virtual private network or VPN in the remote access. Since, the connection is diverted through VPN and it is not done directly, the response time is much more when compared to the direct access (Oberto, 2013). In the remote access strategy, the connection cannot be done with the help of the virtual private network and hence, it is nearly impossible to improve the response time. This is the most significant difference between remote Access strategy and direct access strategy.

The second significant difference between the remote access strategy and direct access strategy is that in the direct access there is a strict restriction of Windows 2008 Server. It cannot work on any other versions of Windows (Jones et al., 2014). This particular type of restriction often becomes a major problem for the direct access and thus restriction is absent in the remote access strategy.

Pros And Cons of Remote Access Strategy

The third important difference between the two strategies of remote access and direct access is that the connections of the direct access are solely established by the machine and not by the user because of the response time (Maiti, Kist & Maxwell, 2015). However, the case is opposite in remote access strategy. The connections through the VPN are done by the users and not by the machines.

The fourth significant difference between the remote access strategy and direct access strategy is that the connection in direct access is bidirectional; whereas that in the remote access strategy is unidirectional for the response time.  

Security is the next important difference between the remote access strategy and direct access strategy. The connections of remote access strategy are not at all secured and there is a high chance that the information could be breached and the hackers would be able to track them easily; whereas, in the direct access strategy, the case is slightly different (Brisaboa, Ladra & Navarro, 2013). The connections of the direct access strategy are extremely safe, secured and authenticated. This makes it extremely popular and well accepted by all users.

Thus, for the higher security and lesser response time, direct access strategy is the best strategy in compared to the remote access strategy.

Conclusion

Therefore, from the above discussion, it can be concluded that, remote access can be defined as the capability of having accessing to any computer or system like the office network computer from the remote location. It eventually allows the employees or staffs to work offsite like in any other location. Remote access is eventually set up with the help of LAN or local area network, WAN or wide area network or a virtual private network or VPN for the purpose of accessing the resources remotely. Direct access, on the other hand is slightly different from the random access. It can be defined as the capability of accessing the physical records that is stored in the discrete locate and thus having a unique address. The above essay has outlined a detailed discussion on the two significant strategies of memory allocation viz. random access strategy and direct access strategy in terms of their response time for any particular organization. This organization has a higher demand of establishment of remote connection. The essay has even highlighted on the functionalities of these two strategies with relevant details. Moreover, the pros and cons of each of the two strategies will also be given here. The essay has also given a comparison between the two strategies.
