I. Vulnerability Assessments A wireless connection in the 20-people organization has the same vulnerabilities that other wireless network. A wireless network has the characteristic that virtually anyone inside the radius of the wireless network could have access to the network, have unauthorized access and create problems with the information flow. The information technicians of the company must consider the following risks and vulnerabilities of the network: Default Keys: They are the passwords that manufacturer brings into the router by default. Several administrators and final users forget to change the default password creating a risk for the organization. The NETGEAR ...

Part 1: Once physical access is obtained by an intruder all security is lost is true because physical access provides an entry even to a reasonable expert to hack and gain access to the network, unencrypted terminals and servers. Wireless networks have not completely decreased the need for hackers to gain physical intrusion as there are vulnerabilities as similar to the wired networks. The systems are exposed to negative forces due to the lack of proper safeguards, as in the case of wireless LANs . Comparing wireless vs. wired security, it is vital to secure a wireless network than to ...

The proposal of the network diagram is conceived to a typical organization which has a finite quantity of peer departments (clients), a department server, plotters and a router with firewall capabilities connected to the internet.

Description of the components of network diagram:

Peer departments (clients): Each department may have one or more terminals that receive service information from a department server. Each client may be a desktop or laptop computer connected to the network by local area network (LAN) of by wireless local access network (WLAN). Each client must have an assigned Internet Protocol (IP) that differentiates one client from another. The use of an ...

Implementation of Authentication Process

The project described focuses on the deployment of WLAN in the school environment as the key aspect of technology application in the education sector both in the primary and secondary schools. The potential user users of WLAN, in this case, are the school non-teaching staff, teachers, and the students.

Probable WLAN Risks

Likely WLAN attacks can be grouped into the passive and active attack. The passive attack will consist of unauthorized access to the network assets with the purpose of traffic analysis. This kind of attack is always not easy to detect because the data remains unaffected and this make the emphasis ...

Wireless LAN has various advantages including cost advantage, convenience and productivity. However, the radio waves subject the network to various risks which can lead to hacking. The three main security issues considered before implementing a Wireless LAN are highlighted hereunder.

Denial of Service

Here, the network intruder floods messages, either valid or invalid, into the network. These messages affect the availability of the resources of the network. WLAN are highly vulnerable against this kind of attack. WLAN has relatively low bit rates which can easily get overwhelmed, exposing them to denial of service attacks. During the implementation of a WLAN, powerful transceiver should be ...
