The scenario described involves the use of a RADIUS (Remote Authentication Dial-In User Service) server. RADIUS is a client-server protocol that provides centralized network authentication12. In this case, the access point (client) forwards the connection request to the RADIUS server, which then sends authentication keys to both the access point and the user’s laptop (supplicant). This process helps the access point identify the wireless client12.

RADIUS servers are also known as AAA (Authentication, Authorization, and Accounting) servers because they provide these three services1. The authentication process begins when a user attempts to log into the network. Their device will request access either through the use of credentials or by presenting an X.509 digital certificate1. The RADIUS server then compares the user’s information with a list of users stored in a directory or IDP (Identity Provider)1.

Therefore, the authentication method demonstrated in the scenario is centralized authentication (Option D), where a central server (in this case, the RADIUS server) handles the authentication of users.

Morris exploited vulnerabilities in the programming logic of an application by employing input validation attacks such as XSS (Cross-Site Scripting). The presentation layer is responsible for handling user interfaces, rendering content, and managing interactions between users and the application. It deals with how data is presented to users and how user input is processed. By manipulating the presentation layer, Morris was able to compromise the application’s security. References: EC-Council Certified Security Specialist (E|CSS) documents and study guide 12.

Messy has deployed an anomaly-based Intrusion Detection System (IDS). This type of IDS observes and compares observed events with normal behavior, detecting deviations from the established patterns. It identifies anomalies that may indicate potential security threats. References: EC-Council Certified Security Specialist (E|CSS) course materials12.
