Badge access and access control vestibule are two of the best ways to ensure only authorized personnel can access a secure facility. Badge access requires the personnel to present a valid and authenticated badge to a reader or scanner that grants or denies access based on predefined rules and permissions. Access control vestibule is a physical security measure that consists of a small room or chamber with two doors, one leading to the outside and one leading to the secure area. The personnel must enter the vestibule and wait for the first door to close and lock before the second door can be opened. This prevents tailgating or piggybacking by unauthorized individuals. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, Chapter 4, pages 197-1981

The SMS OTP (One-Time Password) method is more vulnerable to interception compared to TOTP (Time-based One-Time Password) because SMS messages can be intercepted through various attack vectors like SIM swapping or SMS phishing. TOTP, on the other hand, generates codes directly on the device and does not rely on a communication channel like SMS, making it less susceptible to interception.

To minimize the impact of the increasing number of various traffic types during attacks, a security engineer is most likely to configure behavioral-based rules on a Next-Generation Firewall (NGFW). Behavioral-based rules analyze the behavior of traffic patterns and can detect and block unusual or malicious activity that deviates from normal behavior.

Behavioral-based: Detects anomalies by comparing current traffic behavior to known good behavior, making it effective against various traffic types during attacks.

Signature-based: Relies on known patterns of known threats, which might not be as effective against new or varied attack types.

URL-based: Controls access to websites based on URL categories but is not specifically aimed at handling diverse traffic types during attacks.

Agent-based: Typically involves software agents on endpoints to monitor and enforce policies, not directly related to NGFW rules.

The most likely way a rogue device was able to connect to the network is through a MAC cloning attack. In this attack, a personal device copies the MAC address of an authorized device, bypassing the 802.1X access control that relies on known hardware addresses for network access. The matching MAC addresses in the audit report suggest that this technique was used to gain unauthorized network access.
