About

Internet security is the practice of protecting computers, networks, and data from unauthorized access, use, disclosure, disruption, modification, or destruction. It is a critical issue in today's world, as our reliance on computers and the internet continues to grow.

There are many different aspects to internet security, including:

  • Cryptography: The study of techniques for secure communication in the presence of third parties.
  • Network security: The protection of computer networks from unauthorized access, use, disclosure, disruption, modification, or destruction.
  • Application security: The protection of software applications from unauthorized access, use, disclosure, disruption, modification, or destruction.
  • Data security: The protection of data from unauthorized access, use, disclosure, disruption, modification, or destruction.
  • User awareness: The education of users about internet security risks and best practices.

The field of internet security is constantly evolving, as new threats emerge and new technologies are developed. Researchers in this field work to develop new security techniques and to improve the security of existing systems.

Open Access Policy refers to a set of principles and guidelines aimed at providing unrestricted access to scholarly research and literature. It promotes the free availability and unrestricted use of research outputs, enabling researchers, students, and the general public to access, read, download, and distribute scholarly articles without financial or legal barriers. In this response, I will provide you with an overview of the history and latest resolutions related to Open Access Policy.

Strengthening IoT Network Protocols: A Model Resilient Against Cyber Attacks
by Guy Leshem and Menachem Domb

The pervasive Internet of Things (IoT) integration has revolutionized industries such as medicine, environmental care, and urban development. The synergy between IoT devices and 5G cellular networks has further accelerated this transformation, providing ultra-high data rates and ultra-low latency. This connectivity ena...bles various applications, including remote surgery, autonomous driving, virtual reality gaming, and AI-driven smart manufacturing. However, IoT devices’ real-time and high-volume messaging nature exposes them to potential malicious attacks. The implementation of encryption in such networks is challenging due to the constraints of IoT devices, including limited memory, storage, and processing bandwidth. In a previous work [1], we proposed an ongoing key construction process, introducing a pivotal pool to enhance network security. The protocol is designed with a probability analysis to ensure the existence of a shared key between any pair of IoT devices, with the predefined probability set by the system designer. However, our earlier model faced vulnerabilities such as the “parking lot attack” and physical attacks on devices, as highlighted in the conclusion section. We present a complementary solution to address these issues, fortifying our previous protocol against cyber threats. Our approach involves the implementation of an internal Certification Authority (CA) that issues certificates for each IoT device before joining the network.Furthermore, all encryption keys are distributed by the primary IoT device using the Unix OS ‘passwd’ mechanism. If a device “disappears,” all encryption keys are promptly replaced, ensuring continuous resilience against potential security breaches. This enhanced protocol establishes a robust security framework for IoT networks, safeguarding against internal and external threats.
