Penetration Testing

The WLAN devices are used nowadays in many universities, commercial buildings, and organisations which were developed by Wi-Fi alliance to provide interoperability, security and ease of use of wireless devices connected to everywhere, every time to the internet. The WPA2 standard (IEEE 802.11) defines security mechanisms for wireless networks. This paper describes possible attacks launched on Wireless LAN from pre-connection to gaining access to the system and it represents the effect of these attacks on the WLAN along with some mitigations to prevent the devices from the below-defined attacks.

Wardriving is the practice of searching wireless networks while moving. Originally, it was explicitly referred to as people searching for wireless signals by driving in vans, but nowadays it generally identifies people searching for wireless accesses while moving. Despite the legal aspects, this “quest for connectivity” spawned a quite productive underground community, which developed powerful tools, relying on cheap and standard hardware. The knowledge of these tools and techniques has many useful aspects. Firstly, when designing the security framework of a wireless LAN (WLAN), the knowledge of the vulnerabilities exploited at the basis of wardriving is a mandatory step, both to avoid penetration issues and to detect whether attacks are ongoing. Secondly, hardware and software developers can design better devices by avoiding common mistakes and using an effective suite for conducting security tests. Lastly, people who are interested in gaining a deeper understanding of wireless standards can conduct experiments by simply downloading software running on cost effective hardware. With such preamble, in this chapter we will analyze the theory, the techniques, and the tools commonly used for wardriving IEEE 802.11-based wireless networks.

Rapid Pace

Recently, mobile and wireless devices are being incorporated to the Internet at a rapid pace. This initiates the need for optimizing major applications to perform satisfactorily over wireless links. TCP performance over wireless networks is affected by high link errors, low bandwidth and large delay. Existing well established solutions like the Eifel algorithm, TCP I&RW, TCP SACK and D-SACK attempt to address these issues. However, Eifel or TCP I&RW suffer from ACK losses, while TCP SACK or D-SACK introduce overhead in addition to failure in the presence of multiple packet loss. In this paper, we propose a scheme that overcomes the above problems by introducing a concept of indirect acknowledgment. We name this scheme as TCP IACK. Our proposal exploits TCP timestamp option as an additional identifier to TCP segments for the purpose. Furthermore, it deploys one padding byte following TCP timestamp option to recover from ACK loss. Our proposal is therefore, lightweight, more efficient and robust than existing approaches. We also verify these performance implications through experiments.

The modern development of information technology provides the opportunity to use them in many areas of life, which also include medicine and pharmacy. The introduction of technologies such as an electronic prescription system, drug labeling, creates the prereq-uisites for the remote provision of services. Recently, legislative changes have legalized the distance trad-ing of OTC drugs. In this regard, soon the supply chain of the drug to the end user may include a mini-mum number of professionals. Thus, in these condi-tions, the role of information that users can receive via the Internet is significantly increasing. Such a term as the "usability" of the site, or its ease of use, appeared back in 1998 and every year is of increasing importance. In relation to online pharmacies, the usa-bility assessment is especially relevant in terms of both general functionality, which is typical for all services selling products via the Internet, and features specific to Internet pharmacies only. On May 8, 2020, an anal-ysis of the "usability" of 20 sites of pharmacy organi-zations was conducted. Some advantages were high-lighted (putting information on the quality of goods (declarations, certificates), warnings, contraindica-tions and storage conditions in a separate block), as well as disadvantages (some clutter of the site with elements, the presence of blank pages and a fuzzy warning about prescription drugs).

Commercial banks in Kenya have embraced alternative banking channels which represent a shift in delivery of banking and financial services since the alternative banking have become synonymous with commercial banks in Kenya. While banks have succeeded in leveraging available technology and provide alternative avenues to customers for banking services, the challenge it faces today is optimizing the usage of these channels so as to improve on their performance. The general objective of this study was to investigate the effects of financial innovations on the performance of commercial banks in Kenya. The specific objectives of the study were to examine the influence of internet banking, mobile banking, agency banking and ATM banking on the performance of commercial banks in Kenya. The study was guided by agency theory, balanced score card and diffusion of innovation theory. This study employed a descriptive research design. The study targeted44 commercial banks in Kenya as at 2017. The 16 banks which embrace all the four financial innovations from 2013 to 2017were selected using purposive sampling method. The sample size was 80 respondents who comprised of 5 senior management employees in each of the selected banks.This study used questionnaire to collect primary data from the respondents. Content analysis technique was used to analyze qualitative data collected from open ended questions in and reported in narrative form. Descriptive statistics such as mean and standard deviation were used to analyse the quantitative data. Multiple regression analysis was used to show the relationship between independent variables against dependent variable. The study revealed that internet banking, mobile banking, agency banking and ATM banking had a positive and significant effect on the performance of commercial banks. Thisstudy concludes that the banking industry has benefited tremendously from the development of the Internet. The Internet fundamentally changed the way in which banking networks are designed to meet the client demands and expectations. Mobile banking provides a good opportunity to commercial banks in Kenya to reach many mobile phone subscribers in Kenya who had remained unbanked and unreached due to limited access to bank branch networks in the country. The access to the large masses through mobile banking of the population gives banks the opportunity to grow by reaching the unbanked population. Agency banking has led to accessibility of financial service to many customer in remote areas and hence an increase in effectiveness and efficiency in service delivery. Customers are satisfied with the automated teller machine services because of ease of use, transaction cost and service security but not satisfy with automated teller machine dispense of cash. The study recommends that the public and businesses must be encouraged to use Internet banking in their daily activities, including deposits, payments and money transfers. Commercial banks in Kenya should ensure convenience and security of mobile banking through written guidelines on convenience and security of mobile banking. Commercial banks in Kenya should increase the number of agents in estates and in the rural areas. This can be done by reducing the requirements of becoming a bank agent. The banks should employ customized software that records relevant information on automated teller machine cards so that banks can establish whether unauthorized transaction has taken place or not.

The Internet Of Things

Latency-sensitive applications for the Internet of Things (IoT) often require performance guarantees that contemporary wireless networks fail to offer. Application scenarios involving real-time control of industrial machinery, robotics, or delay-sensitive actuation therefore typically still rely on cables: today's wireless networks cannot deliver messages in a sufficiently small and predictable amount of time. Drop-in wireless replacements for these cabled systems would nevertheless provide great benefit by eliminating the high cost and complexity associated with running cables in harsh industrial environments [1]. The symbolsynchronous bus, introduced in this article and embodied in a platform called Zero-Wire, is a novel wireless networking paradigm that addresses this gap. Using concurrent optical transmissions, it strives to bring low-latency deterministic networking to the wireless IoT.
