SC-100 Zero Trust & Threat Protection Solutions — Questions and Answers

Question 1: What is the core principle of the Zero Trust model?

Trust all internal users.
Trust only verified and continuously validated users and devices (Correct answer)
Disable user authentication.
Allow full access by default.

Correct answer: Trust only verified and continuously validated users and devices

The core principle of the Zero Trust model is 'never trust, always verify.' It assumes that no user or device, whether inside or outside the network perimeter, should be implicitly trusted. Instead, every access request must be explicitly verified, authenticated, and authorized based on context and policy before access is granted, and then continuously monitored.

Question 2: What is micro-segmentation in Zero Trust architecture?

A network design for internet access.
Allowing users to bypass firewalls.
Creating small, secure zones within the network (Correct answer)
Providing public IPs to all users.

Correct answer: Creating small, secure zones within the network

Micro-segmentation is a key component of Zero Trust architecture that involves dividing a network into isolated, granular security segments down to the workload level. This allows for fine-grained security policies to be applied to each segment, limiting lateral movement of threats even if one segment is compromised. It significantly reduces the attack surface and contains breaches.

Question 3: Why is continuous monitoring important in threat protection?

To block all users.
To update software only once a year.
To detect anomalies and respond to threats promptly (Correct answer)
To reduce internet speed.

Correct answer: To detect anomalies and respond to threats promptly

Continuous monitoring is crucial in threat protection because it provides real-time visibility into an organization's security posture, network traffic, and system behavior. By constantly analyzing data for anomalies and indicators of compromise, organizations can detect and respond to emerging threats and attacks quickly. This proactive approach minimizes the impact of security incidents.

Question 4: What is a key element of threat protection strategy?

Ignoring system logs.
Only using basic passwords.
Using proactive and reactive security tools (Correct answer)
Restricting all network traffic.

Correct answer: Using proactive and reactive security tools

A comprehensive threat protection strategy relies on a combination of proactive and reactive security measures. Proactive tools aim to prevent attacks, while reactive tools focus on detecting, responding to, and recovering from incidents that bypass initial defenses. This layered approach ensures robust defense against a wide range of cyber threats.

Question 5: Which tool helps detect advanced persistent threats (APTs)?

Firewall
Email client
Endpoint Detection & Response (EDR) (Correct answer)
Text editor

Correct answer: Endpoint Detection & Response (EDR)

Endpoint Detection & Response (EDR) tools are specifically designed to continuously monitor endpoint activity, collect and analyze data, and detect sophisticated threats like Advanced Persistent Threats (APTs). EDR goes beyond traditional antivirus by providing deeper visibility, behavioral analysis, and automated response capabilities to identify and contain stealthy attacks that might evade other defenses.

Question 6: What does 'assume breach' mean in Zero Trust?

No validation needed.
Design as if a breach has already occurred (Correct answer)
Trust all software updates.
Permit anonymous access.

Correct answer: Design as if a breach has already occurred

The 'assume breach' principle in Zero Trust means that organizations should design their security architecture and incident response plans with the mindset that a breach is inevitable or has already happened. This leads to implementing controls like micro-segmentation, strong authentication, and continuous monitoring to limit the damage and quickly detect and respond to an attacker who has gained initial access.

Question 7: Which type of attack is Zero Trust designed to limit?

DDoS
Lateral movement within networks (Correct answer)
Phishing
Spam

Correct answer: Lateral movement within networks

Zero Trust is specifically designed to limit lateral movement, which is when an attacker gains initial access to one part of a network and then moves horizontally to access other systems or data. By implementing strict authentication, authorization, and micro-segmentation for every access request, Zero Trust prevents attackers from easily spreading across the network, even if they compromise an endpoint.

Question 8: What is the purpose of identity verification in Zero Trust?

To simplify sign-up forms.
To provide access without checks.
To confirm users are who they claim to be (Correct answer)
To disable user roles.

Correct answer: To confirm users are who they claim to be

In a Zero Trust model, identity verification is paramount, as the core principle is 'never trust, always verify.' Every user and device attempting to access resources must be explicitly and continuously verified to confirm their identity and legitimacy. This typically involves strong authentication methods like MFA and continuous evaluation of contextual factors, ensuring that only authenticated and authorized entities gain access.

Question 9: How does threat intelligence contribute to Zero Trust?

It slows down the system.
It blocks all traffic.
It enhances situational awareness and threat response (Correct answer)
It removes security patches.

Correct answer: It enhances situational awareness and threat response

Zero Trust operates on the principle of "never trust, always verify." Threat intelligence provides crucial, real-time context about current and emerging threats, vulnerabilities, and attack patterns. This information enables Zero Trust systems to make more informed access decisions, detect anomalies, and respond proactively to potential breaches, thereby significantly enhancing an organization's security posture and resilience.
