How to use blockchain to enhance network protocol security?4 answersBlockchain can be used to enhance network protocol security in several ways. One approach is to use blockchain for secure routing in wireless sensor networks (WSNs) by implementing an improved blockchain-based encryption scheme. Another method is to utilize a distributed blockchain database to store authentication records and construct a secure overlay network in IoT networks. Additionally, blockchain technology can provide security for routing on the Internet by implementing a less centralized model. Furthermore, a blockchain-enabled trusted protocol can be designed to control user behavior and improve the security capability of the network. Finally, blockchain can be used to enable protected communication between Internet of Drones environments, enhancing the security of data transmission and storage.
What causes Credentials from Password Stores network protocol error?4 answersCredentials from password stores network protocol error can be caused by vulnerabilities in the authentication process and undetectable online attacks. One paper by Gesquiere et al. proposes a protocol where credentials are transferred in a network by encrypting them and transmitting encryption keys to the access point and new device. Another paper by Tsang et al. discusses a device that authenticates clients based on a comparison of password forms stored in a database and received from the client device. Tallapally's paper highlights the vulnerability of a three-party authenticated key exchange protocol to undetectable online attacks. Krivosheev et al. suggest using domain verification services to prevent fraudulent requests for login credentials. Lastly, Lee et al. identify vulnerabilities in an optimal strong password authentication protocol, specifically vulnerability to guessing attacks.
Why network security is important?4 answersNetwork security is important because it involves protecting data and computer systems from potential threats such as cyber attacks, malware, and data theft. With the increasing interconnectedness of the digital era, the need for robust network security has become critical. The introduction of the Internet has brought about numerous security issues, making network security even more important. It is necessary to safeguard the network architecture and protect against unauthorized access and cyberattacks. Without the right protection in place, data and personal information can fall into the wrong hands. Network security encompasses technology and policies that ensure the safety, integrity, and availability of data and personal information. Overall, network security is essential in the rapidly evolving digital environment to prevent disruptions, unauthorized access, and data breaches.
How does security help online courseware?5 answersOnline security helps in various ways to enhance the effectiveness and integrity of online courseware. Firstly, incorporating online security into the curriculum of higher education institutions can protect both students and institutions from risks to privacy and security, ensuring a safe learning environment. Secondly, implementing strategies to improve test security in online classrooms helps maintain academic integrity in student evaluation. Additionally, ensuring the security of courseware distribution is crucial to prevent unauthorized access and the spread of computer viruses. Lastly, focusing on data security in online courses is essential as more data are shared over the internet, protecting sensitive information from hacking incidents and loss. By addressing these security concerns, online courseware can provide a secure and trustworthy learning experience for students and educators.
