Cyber Midterm

Network Access Control (NAC) is a security mechanism that manages and restricts access to a network based on predefined policies. It ensures that only authorized users and devices can connect to the network, protecting it from unauthorized access or potential threats. NAC enforces rules like device authentication, security posture assessment, and user permissions. It helps maintain network security by controlling who can access resources and under what conditions.

Design vulnerabilities refer to weaknesses in the architecture or design of a system or application that can be exploited by attackers. These vulnerabilities arise from poor planning, improper security controls, or overlooked risk factors during the design phase. They can lead to issues like insufficient authentication, weak data validation, or lack of proper access control. Addressing design vulnerabilities early in development helps reduce the risk of security breaches and system failures.

White-box testing involves testing the internal structures or workings of an application, where testers have access to the source code and design documents. It focuses on verifying the logic, flow, and functionality of the code. Black-box testing, on the other hand, tests the software without knowledge of its internal workings. Testers focus on input-output behavior and validate whether the system meets user requirements and performs as expected. Gray-box testing is a hybrid approach, wher...
