Multi-Factor Authentication (MFA) and patch management are both examples of preventative and technical controls. MFA prevents unauthorized access by requiring multiple forms of verification, and patch management ensures that systems are protected against vulnerabilities by applying updates. Both of these controls are implemented using technical methods, and they work to prevent security incidents before they occur.

An unknown environment in penetration testing, also known as a black-box test, simulates an actual external attack where the tester has no prior knowledge of the system. This type of penetration test is designed to mimic real-world attack scenarios, where an attacker has little to no information about the target environment. The tester must rely on various reconnaissance and attack techniques to uncover vulnerabilities, much like a real-world attacker would. This approach helps organizations understand their security posture from an external perspective, providing insights into how their defenses would hold up against a true outsider threat.

Software as a Service (SaaS) is the cloud model that best meets the goal of outsourcing the management, including patching, of firmware, operating systems, and applications to the cloud vendor. In a SaaS environment, the cloud provider is responsible for maintaining and updating the entire software stack, allowing the organization to focus on using the software rather than managing its infrastructure.

Risk threshold is the maximum amount of risk that an organization is willing to accept for a given activity or decision. It is also known as risk appetite or risk tolerance. Risk threshold helps an organization to prioritize and allocate resources for risk management. Risk indicator, risk level, and risk score are different ways of measuring or expressing the likelihood and impact of a risk, but they do not describe the maximum allowance of accepted risk. References: CompTIA Security+ Study Guide: Exam SY0-701, 9th Edition, page 34; Accepting Risk: Definition, How It Works, and Alternatives
