Wireless security beyond 802.1x Essay Example | Topics and Well Written Essays - 500 words

Wireless security beyond 802.1x - Essay Example However, many consider the IPsec an improvement on the 802.1x. However, to ascertain the truth, we need to carry out an analysis of the protection provided by the different technologies. The 802.1x assists in controlling access to a computer network. The technology is a port-based access control method that is defined by the Institute of Electrical and Electronics Engineering which can be configured to require mandatory authentication between the network and the client. Communications become impossible without the authentication. Many people consider the 802.1x technology as the foundation of wireless security. However, deploying the 802.1x technology has its challenges. The technology requires devices that are compatible with 802.1x . The technology has weakness in its protocol, as it only authenticates at the establishment of a connection. Further connection does not require authentication, resulting in security risks (Al-Shaer, 2014). Additionally, the technology does not have centralized management capability. As such, the IPsec VPN became introduced. The Virtual Private Networks based on IPsec allow a layer of security to become a part of the wireless network, allowing for the protection of all traffic that flows in and out of the network. The method has several advantages over 802.1x including; Invisibility - Since the technology is based at the network level, it remains invisible in its operations (Snader, 2014). The end users do not have to learn its existence, nor do they have to interact directly with it, which is different from the 802.1x technology that requires authentication from clients. Lack of dependence on applications - The IPsec technology does not depend on applications to become effective, as the s=entire system is operated at the network level. As such, it avoids compatibility issues, which are common in 802.1x systems. Broken algorithms - A number of key algorithms used by the IPsec have been cracked,

Drinking age - Essay Example Moderation will lead to results that are more realizable as compared to the minimum drinking-age restrictions. Certainly, under-age drinking is a prevalent problem especially among Americans. Different control measures have been taken to address the issue. However, each one of them has its advantages and disadvantages. I agree with the author that responsible drinking should be encouraged. This is even more important when dealing with a revolutionized society. The present youth develop in all aspects at a very fast rate as compared to the ages of our parents. Therefore, imposing stern legal restrictions regarding drinking may not realize the desired results. Instead, guidance and mentorship should be preferred. Provisional drinking license seems to be the best way forward. Introduction to drinking should be stepwise. This will eliminate dangerous drinking such as binge drinking. Hanson et al feels that prohibiting age is not a good solution. I agree with him since there are cases of adults experiencing irresponsible drinking. In fact, responsible drinking is also common among young adults who have not yet reached drinking age. Jenna Bush is a good example of responsible drinking among young adults. Although she was highlighted for under-age drinking, her drinking was responsible. Undeniably, responsible driving is gained through gradual introductory classes. The same case should be emulated for responsible drinking among young adults. However, one-sided approach cannot work effectively. Although the author advocates for drinking permit, the idea cannot work without rules and guidelines. The drinking permits ought to be followed by strict regulations to make them effective. For example, it would be good if the permits specified that an adult such as a parent be present at the time of drinking. This way, the parent, mentor, or the guide would be
