Recently, the security of an individual computer to large networks as a result of a dramatic growth of new devices connecting to the internet, has become one of the biggest challenges. Along with growing new types of security attacks, many protection mechanisms have taken to improve the privacy and security of sensitive information. Detection of abnormal behavior can help network administrators to identify intrusions but cannot prevent them from breaking into home network. Furthermore, using traditional methods which firewall and IDPS systems reside in different machines that results to low performance by filtering and checking traffic in multi points. This paper is providing an efficient and cost effective method of both detecting and preventing network threats. To achieve such goal, we are using a form Snort, Suricata, and Bro IDPS Systems.
Cloud-based Applications are suitable tools in the E-learning system, and they bring the most facilities in E-learning due to availability and on-demand self-services. During Covid-19 lockdown, while presential learning stopped and E-learning started. The Ministry of Higher Education has begun E-learning in public and private universities. Therefore, Afghanistan’s universities used Cloud-based Apps in E-learning, but these Apps are not identifying and ranking in the E-learning of Afghanistan. This study aims to identify and rank the Cloud-based Apps in terms of usefulness and effectiveness in E-learning using state-of-the-art, and its usage in public universities of Afghanistan. To get an accurate answer to the defined questions, mixed research was used. Therefore, an online questionnaire was distributed randomly to six public universities in six different parts of Afghanistan. The respondents were divided into two categories (lecturers and students) and asked to respond to Cloud-based Apps usage and effectiveness in E-learning. The responses were analySed using Chi-Square Tests. The result showed the most, low, and lowest useful Cloud-based Apps in E-learning. In conclusion, the research finding showed that Google Classroom was the most LMS, WhatsApp was the most mobile instant messaging, Gmail was the most E-mail server and Skype was the most video conferencing Cloud-based Apps in E-learning in most public universities of Afghanistan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
