Outbreaks will continue to occur, and so the diseases' transmission method must be thoroughly understood in order to minimize their impact. Some infections, such as influenza, tuberculosis and measles, known to spread through droplets in the air. In a confined space, the concentration can grow as more droplets released. This study examined a simulated confined space modelled as a hospital waiting area, where people who could have underlying conditions congregate and mix with potentially infectious individuals. It further investigated the impact of the volume of the waiting area, the number of people in the room, the placement of them as well as their weight. The simulation is an agent-based model (ABM), a computational model with the purpose of analyzing a system through the actions and cumulative consequences of autonomous agents. The presented ABM features embodied agents with differing body weights that can move, breathe and cough in a ventilated room. An investigation into current epidemiological models lead to the hypothesis that one may implement as a corresponding ABM, where it could possibly, also be improved upon. In this paper, it has shown that, all parameters of the Gammaitoni and Nucci model, been taken into account, in an ABM via the MASON library. In addition, proof produced, suggested that some flaws of the epidemiological model, should be amended in the ABM. It was demonstrated, the constructed model, account for proximity between susceptible people and infectors, an expressed limitation of the original model.

In recent times hackers have been engaging in different string concept on login fields and phishing in order to intrude cloud accounts. This research is proposed to carry out effective security mechanisms on loopholes in cloud data storage. We intend to engage the use of the Advanced Encryption Standard (AES), security Algorithms like Secure Hash Algorithm 1 & 3 (SHA1, SHA 3) and Message-Digest Algorithm (MDS) and the Standard Authentication Scheme (AS) as sure guide against phishing which when implemented can provide various login stages and codes like OTP (One Time Password) to mitigate attacks. With the application of these methods towards securing cloud computing data there will be less intrusion in accounts and loss of files.

The quest for the application of tighter security measures to web, desktop and mobile applications developed has been a major concern to a lot of people. Faced with the challenges of poor security and vulnerability of users, resulting to applications being hacked by unauthorized people, this research delved into developing a more secured login application that sends a secret pass code to the registered phone number of a user for identification purpose. The aim of the application is basically to ensure that users are safe, and all logins are authorized. The application was developed with PHP, MYSQL, CSS, BOOTSTRAP, HTML technologies and WAMP Server.

Framing the Attacker in Organized Cybercrime

Advances in Multidisciplinary and Scientific Research Journal, Jan 30, 2022

When large values are at stake, the attacker and the attacker's motives cannot be easily modeled,... more When large values are at stake, the attacker and the attacker's motives cannot be easily modeled, since both the organization at stake and the possible attackers are unique and have complex motives. Hence, rather than using stereotypical attacker models, recent work proposes realistic profiling of the opponent by the use of usercentered design principles in form of the persona methodology. Today, cybercrime is often organized, i.e., attacks are planned and executed by an organization that has put together a tailor-made team consisting of the necessary skills for the task. The actual individuals taking part in the attack might not be aware of or interested in the overall organizational motives. Rather, taking motives behind espionage, fraud, etc., into account requires consideration of the attacking organization rather than the individuals. In this paper, based on interviews with IT security experts, we build on the attacker persona methodology and extend it with methodology to also handle organizational motives in order to tackle organized cybercrime. The resulting framework presented in the paper extends the attacker persona methodology by also using narratives in order to assess the own organization's security. These narratives give rise to intrigue sketches involving any number of attacker personas, which hence, make it possible to take organized cybercrime into account.

'While in some crimes, one component of the crime may have been committed using an electronic instrument, in other crimes, the crime as a whole is committed in the online or electronic environment. These crimes, known as cybercrimes, generally occur in the virtual community of the Internet or in cyberspace. As a result of this, all innocent internet users should inculcate the habit of continuously updating their knowledge about the ever changing nature of information technologies. We explore the various types of cybercrimes in Nigeria, their causes, effects and perception of cyber crimes and cyber security among users of the cyberspace

According to Gartner, while the hype grew exponentially during 2008 and continued since, it is clear that there is a major shift towards the cloud computing model and that the benefits may be substantial (Gartner Hype-Cycle, 2012). However, as the shape of cloud computing is emerging and developing rapidly both conceptually and in reality, the legal/contractual, economic, service quality, interoperability, security, and privacy issues still pose significant challenges. In this chapter, the authors describe various service and deployment models of cloud computing and identify major challenges. In particular, they discuss three critical challenges: regulatory, security, and privacy issues in cloud computing. Some solutions to mitigate these challenge...

In order to increase the efficiency of COVID- 19 detection, computer vision based systems can be used. However, a large set of training data is required for creating an accurate and reliable model, which is currently not feasible to be acquired considering the novelty of the disease. Other models are currently being used within the healthcare sector for classifying various diseases, one such model is for identifying pneumonia cases by using radiographs and it has achieved high enough accuracy to be used on patients [18]. With the background of having limited data for COVID-19 identification, this thesis evaluates the benefit of using transfer learning in order to augment the performance of the COVID-19 detection model. By using pneumonia dataset as a base for feature extraction the goal is to generate a COVID-19 classifier through transfer learning. Using transfer learning, an accuracy of 97% was achieved, compared to the initial accuracy of 32% when transfer learning was not used.COVID-19 är för närvarande en pågående pandemi och det är en stor efterfrågan på tester, Vilket har lett till att resurserna på sjukhusen inte räcker till. I syfte att öka effektiviteten för COVID-19 tester kan datorsynbaserade system användas. En datorsynsbaserad klassificerare kräver en stor uppsättning träningsdata för att kunna skapa en noggrann och pålitlig modell, vilket för närvarande inte är tillgängligt eftersom sjukdomen endast har existerat i några månader. Diverse modeller används inom sjukvårdssektorn för klassificering av olika sjukdomar. Klassificering av lunginflammationsfall med hjälp av röntgenbilder är ett av de områden där modeller används. Modellerna har uppnått tillräckligt hög noggrannhet för att kunna användas på patienter [18]. Eftersom datamängden är begränsad för identifiering av COVID-19 utvärderar detta arbete nyttan med att använda överföringsinlärning i syfte att förbättra prestandan i COVID-19-detekteringsmodeller. Genom att använda Lunginflammations bilder som en bas för extraktion av attribut, är målet att generera en COVID-19 klassificerare genom överföringsinlärning. Med användning av denna metod uppnåddes en noggrannhet på 97 % jämfört med den ursprungliga noggrannheten på 32 % när överföringsinlärning inte användes
