Facial recognition is a type of biometric authentication that uses the unique features of a person’s face to verify their identity. Facial recognition is not something you know or have, but something you are, which is one of the three factors of authentication. Facial recognition can use various methods and technologies, such as 2D or 3D images, infrared sensors, machine learning and more, to capture, analyze and compare facial data. Facial recognition can provide a convenient and secure way to authenticate users on personal mobile devices, as it does not require any additional hardware or input from the user. Facial recognition can also be used in conjunction with other factors, such as passwords or tokens, to provide multi-factor authentication. Verified References:

The most likely cause of the issue is that the S/MIME plug-in is not enabled. S/MIME stands for Secure/Multipurpose Internet Mail Extensions, which is a standard that allows email users to encrypt and digitally sign their messages. S/MIME uses public key cryptography and certificates to ensure confidentiality, integrity, authenticity, and non-repudiation of email communications. However, S/MIME requires both the sender and the receiver to have compatible email clients and plug-ins that support S/MIME functionality. If the receiver does not have the S/MIME plug-in enabled, they will not be able to decrypt or verify the encrypted message.

A web application firewall (WAF) is a security solution that monitors and filters the traffic between a web application and the internet. It can prevent code injection attacks by blocking malicious requests that contain code snippets or commands that could compromise the web application. A WAF can also enforce input validation rules and sanitize user inputs to prevent code injection. References: CompTIA Security+ SY0-601 Certification Study Guide, Chapter 4: Implementing Secure Network Designs, page 194; 5 ways to prevent code injection in JavaScript and Node.js
