The Internet Protocol (IP) defines the fundamental rules for transmitting data across networks. The two primary versions in use today are IPv4 (Internet Protocol version 4) and IPv6 (Internet Protocol version 6). These protocols differ not only in their addressing schemes but also in their data transmission methods. This article provides an in-depth comparison of … Read more

RBAC (Role-Based Access Control) is an access control model that assigns permissions to specific roles rather than individual users. Users are then assigned to roles, which determine their level of access to resources. This approach enhances both security and operational efficiency, making it widely used in organizations and enterprises. Key Concepts of RBAC Role: Represents … Read more

In network security, various attack techniques exist, and among them, Switch Jamming is known as a form of sniffing attack. This attack floods the network with forged MAC addresses, causing the switch’s MAC address table to overflow, rendering it unable to operate normally. In this article, we will explore the concept, working mechanism, attack tools, … Read more
