Why is the internet important to security?
So, here the requirement is to ensure that the services are supplied to a legitimate user rather than bots to prevent service abuse. The present article provides such a security from bots with the help of a standard security mechanism called CAPTCHA. A new cognition-based design of CAPTCHA is produced overcoming the limitation of presently available CAPTCHA. Also, a new architecture for producing these CAPTCHA codes randomly is presented in this article so that the differentiation among a legitimate user and Bots can be made. Thus, the major objective of the article is to present an optimum security mechanism for differentiating among humans and Bots.
Why is the network important for education?
The key aim of education is to share data and knowledge, making the network important for education. In particular, it is essential to ensure the exchange of information; thus, no one can corrupt it. To safe and trustworthy transfers between users, integrity and reliability are crucial questions in all data transfer problems. Therefore, we have developed a secure campus network (SCN) for sending and receiving information among high-security end-users. We created a topology for a campus of multi networks and virtual local area networks (VLANs') using cisco packet tracer. We also introduced the most critical security configurations, the networking used in our architecture. We used a large number of protocols to protect and accommodate the users of the SCN scheme.

What is network information system?
Enterprise Network Information System is not only the platform for information sharing and information exchanging, but also the platform for Enterprise Production Automation System and Enterprise Management System working together. As a result, the security defense of Enterprise Network Information System does not only include information system network security and data security, but also include the security of network business running on information system network, which is the confidentiality, integrity, continuity and real-time of network business. According to the security defense of Enterprise Network Information System, this paper proposes the "network business security" concept. In this paper, the object of information security is defined in three parts - - data security, network system security and network business security, and the network business security model is described. The proposal of the concept "network business security" provides theoretical basis for security defense of enterprise automatic production system and enterprise management information system.
Why is mobility important in universities?
Mobility becomes a requirement in most universities especially after the enhancement that took place in the new technologies. Besides, the university must be fully linked to the Internet and network facilities available in the campus. The major factor that should be considered is the security of the university network. The current network security in the universities is still weak to be implemented; students still can break through the staff and faculty members' computers trying to hack the confidential information. This paper addresses the internal and the external security challenges in universities that implements wireless networks. Distributed security is designed to provide a more secure data communication among faculty members, staff, and students. A description of the technique used to protect and keep PC's up and running is illustrated with applications

What are the problems of remote labs?
Problems related to data security issues, information and access credibility are the main points encountered today for remote laboratories. Because of the use of an Internet connection, there is a need for an efficient mechanism to ensure secure and authenticated access to resources provided by the laboratories. The purpose of the research is to find solutions for the primary forms of attacks on remote labs since they are a much more efficient way in terms of accessibility and availability when compared to conventional labs. Defining which methods are adopted nowadays is the main objective that must be reached at the end of the work. Initially, a research of the current security methods of remote laboratories was carried out, which are the most frequent forms of attacks that occur today. As a result, there should be a new implementation of security-related issues. Thus, network security devices consist of one or more security functions, so that there is protection in any kind of attack. As a result, it is also expected the definition of which security methods can be adopted by remote laboratories, showing where security improvements should occur so that major attacks are avoided. Based on this context, this work intends to provide an advance in security practices to be adopted as well as ensure that the main attacks that currently occur will not affect the integrity of laboratories.

David Creelman, HR thought leader and the CEO of Creelman Research in Toronto, said that employers can try to ban the use of popular but not approved communication methods, "but we need to accept that humans will inevitably circumvent the policy. That means we need a second layer of defense: education. HR professionals need to be educated and reminded which data is so sensitive that they must never take a risk with it. If employees' compensation data or medical data or psychometric assessment data is revealed, that's very serious."
Can you use personal devices for cybersecurity?
Many workers will have no choice but to use personal devices and home networks to get their job done.
