Wireless Security Technology

Introduction

Wireless network threats are passive and active. Passively, your network can be intercepted by other unauthorized users without even being connected if they install their card in "monitor" mode. Using tools such as Wireshark, they can then intercept email, listen to VOIP conversations, read instant messages as well as enjoy your network traffic, stealing cookies to validate themselves as the authorized user to web sites.

Actively, you can become vulnerable to "Man in the Middle" attacks, which enable a hacker to place themself between you and a web page you are accessing – one famous tool replaces all images loading on pages with those of sheep or even usurp the identity of the router altogether (Rittinghouse & Ransome, 2020). This enable them to intercept an aware user's banking sessions, access any sites using your address, and basically blackmailing users not to mention injecting hostile code on otherwise trusted pages which can then infect your computer with a more lasting lament.

One of the most basic things one can do to secure wireless network is to change the username and password of the router (Choong & Lim, 2019). Use of complex passwords will help you in being more secure. Activating Encryption is another important thing you should do. This can be done by changing the Router settings. Turning off guest networks can be the other option which will prevent anyone from using your network without username and password.

Problem Statement

In wireless networks, the most common issues are access to private networks via an open hot-spot or access to private information by sniffing wireless traffic at a public place, like those commercials where someone sitting at a local coffee-shop is sniffing everyone’s personal data. These strategies are obscure to common PCs users however among those with even a minor measure of information, those exercises can be performed with little trouble. Nearly anyone with the desire to do so could setup shop and sniff passwords or whatever information they’re looking for. This activity is limited by the normal utilization of VPNs and SSL.

Another normal security weakness is admittance to private organizations by means of the Internet. Additionally, Web page defacing has become normal for the most part since it's moderately simple to do by hackers. Data-communications over the internet if unsecured by a VPN have their most common security vulnerabilities, Man in the Middle, port-spanning (or tapping), and spoofing. Wireless devices security protocols is a nightmare. Manufacturers of this devices fail in developing a robust security protocol to their devices including routers and switches hence making them vulnerable to attacks.

Relevance and Significance

While setting up wireless network for a business, safety efforts ought to be on the first spot on the list. One of the biggest concern surrounding wireless network is ensuring that the network is secure from unauthorized access (Soyinka, 2019). Wireless network cannot be 100% secure but the following security measures must be put in place to enhance wireless security in any organization. Organizations should ensure that sufficient physical security controls are set up.

Extra physical safety efforts might be expected to ensure WLAN network components installed throughout the facility, like access point (AP) are protected from burglary, interference, as well as abuse. Organization likewise need ponder the scope of each AP concerning the workplaces' actual limits; communication that stretch past these limits are helpless against spying by external parties.

Organization worried about snooping threats should restrict legacy WLAN signal proliferation, at least with the goal that it doesn't go past the physical control limits of the organization’s facilities. In any case, there is dependably a probability that an attacker may use a high-gain antenna from a moderately long distance to listen stealthily, so only by using solid cryptographic means can any confirmation of security against spying be accomplished.

Wireless access point frequently have vulnerabilities and different shortcomings in their default configuration. Organizations ought to guarantee that access point management is configured appropriately. This incorporates configuring administrator access, controlling the access point reset feature, configuring network administration protocols, and activating logging. Organizations must also guarantee that APs are configured to enhance a safe WLAN setup.

Wireless networks is a first developing innovation and is set to keep on developing in the future. It is perceived that wireless networks could offer benefits to the community in the quest for its primary objectives (Nichols & Lekkas, 2018). The ongoing approval of 802.11 models for wireless access will keep on developing enthusiasm for the innovation which is by its inclination moderately clear to implement. While this might be valid and appropriate for some environment, wireless network form some portion of the greater infrastructure which comprise the wired network.

In order to secure the business needs of the wireless network must meet a similar dimension of security used by the rest of the infrastructure. Wireless network offers a suitable way for accessing client resources. Wireless innovation have turned out to be universal in the workplace environment. The arrival of wireless innovations adds more functionality but additionally introduce security threats and concerns that must be monitored and relieved.
