“…Chaudhary et al the. Worked on a short-lived threat model to gain acceptance against PC clients and performed an estimation impact analysis of two popular risk evocation frameworks, STRIDE and LINDDUN [18]. The results show that the machine developer wants to understand the adversary in the evolving context within the systems function and, more importantly, mitigate it by re-certifying the boundaries in such a way that those within the administrative boundaries cannot violate their protective and private properties.…”

Utilizing of the WhatsApp application in recent years, especially in the last ten years, is an increasing use and the way it is exponentially increasing. With the development of mobile phone generations and what the fifth generation technology (5G) is looking forward to, it become necessary to have a mechanism that controls the traffic in the WhatsApp application in the fifth generation technology (5G). In this article, a model called WhatsApp Traffic Control Time-Based (WTCTB) was proposed, which synchronizes with WhatsApp usage times and reduces traffic in secondary-priority applications as well as saving time consumption for traffic flow in addition to saving energy consumption in the phone battery in the sixth generation mobile networks. WhatsApp application is normally consuming more than 40% in almost smart phones of their battery energy, the proposed model WTCTB is reducing this consuming rate to be 35%.

“…That exposed users of desktop clients to various threats [85]. Particularly in the context of victims of intimate partner violence or users of managed devices [86]. This means that with the evolution of features to existing security mechanisms like MFA to enable wider participation of disadvantaged groups needs to be accompanied by appropriate scoping of emergent threats.…”

“…Communication of breaches and their subsequent recovery can be looked from the wider prism of security audit functions [87]. A scrutiny of the E2EE mechanisms reveal that some of them expect the user to detect and recover from breaches while some others leave the user out of the loop to detect such breaches and recover from them [86]. There needs to be mechanisms to communicate threats, breaches and recovery in a manner appropriate to the deprivations of the individuals they are meant to protect.…”

We inhabit a 'digital first' society, which is only viable if everyone, regardless of ability and capacity, is able to benefit from online offerings in a safe and secure way. However, disabled individuals, people living under oppressive regimes, elderly citizens and individuals fleeing conflict can be excluded, because they might not have the opportunity to implement cybersecurity hygiene measures. To reduce this potential exclusion, it is crucial to make all users' situated realities focal variables in policy debates and provisioning efforts. This requires a validated set of basic minimum capabilities which reflect individuals' diverse personal and social realities. In this paper, we report on a scoping literature review intended to reveal the state of play with respect to capabilities-related research in the cyber domain. We motivate our initial focus on the over 65s for this investigation. We used advice from online government cybersecurity advisories to arrive at a set of five recommended cybersecurity hygiene tasks. These fed into a survey with sixty senior citizens to elicit the barriers they could envisage someone of their age encountering, in acting upon cybersecurity hygiene advice. The final deliverable is a candidate list of basic capabilities (cybersecurity) for seniors. This enables us to start measuring security and privacy poverty, an essential step in recognising and mitigating exclusion, as well as informing threat modelling efforts.
