A hacker wants to discover login names that may exist on a website. Which of the following responses to the login and password entries would aid in the discovery? (Choose two.)
Correct Answer:
A, C
Explanation
When a website responds differently to wrong passwords versus non-existent usernames, attackers can enumerate valid accounts. Responses like 'Your login attempt was unsuccessful' or 'That user does not exist' reveal which usernames are registered. This information helps attackers focus their efforts on known accounts for password attacks. Generic messages like 'Invalid credentials' prevent this enumeration by treating all failures the same way.
Accompany collects and stores sensitive data from thousands of IoT devices. The company's IoT security administrator is concerned about attacks that compromise confidentiality. Which of the following attacks is the security administrator concerned about? (Choose two.)
Correct Answer:
B, E
Explanation
Aggregation and inference attacks threaten confidentiality by exposing sensitive information through data analysis. Aggregation combines multiple data points to reveal patterns or secrets that individual pieces would not. Inference uses available data to deduce private information, like determining health conditions from device usage patterns. Both attacks compromise what IoT systems reveal about users even when individual data points seem innocuous.
Which of the following techniques protects the confidentiality of the information stored in databases?
Correct Answer:
D
Explanation
A hacker can forge a trusted certificate when they gain access to the certificate authority's private key. If that key is stored in unsecure flash memory on the IoT device instead of a hardware security module, an attacker who compromises the device can steal it. Once they have the private key, they can generate fake certificates that appear legitimate. Poor certificate storage directly enables certificate spoofing attacks. This is a firmware and software security issue.
Which of the following attacks utilizes Media Access Control (MAC) address spoofing?
Correct Answer:
B
Explanation
Rainbow tables are precomputed lists of password hashes that hackers use to crack passwords quickly. Role-based access control limits what actions each user can perform based on their role, but it doesn't stop someone from using a compromised password. The real mitigation is adding salt to passwords during hashing or implementing multi-factor authentication. However, role-based access does limit damage if an account is breached. The question asks what to do after the attack is discovered, making access control the best available answer.
A hacker wants to record a live session between a user and a host in hopes that parts of the datastream can be used to spoof the session. Which of the following attacks is this person attempting?
Correct Answer:
B
Explanation
IPSec with Authentication Headers detects when packets have been altered in transit. The AH component adds a cryptographic hash that changes if anyone modifies the packet data. If an attacker injects or modifies packets, the hash no longer matches and the packet is rejected. This makes it impossible to insert malicious packets without detection. Other technologies like firewalls or VPNs protect the network but don't specifically detect injection attacks the way authenticated encryption does.
Requiring randomly generated tokens for each connection from an IoT device to the cloud can help mitigate which of the following types of attacks?
Correct Answer:
D
Explanation
Two-factor authentication requires something you know (your password) plus something you have (like a phone or hardware token). Even if a hacker steals the password through phishing, they can't access the account without the second factor. Single sign-on or certificate pinning don't add a second authentication layer. Implementing 2FA directly prevents unauthorized access even when passwords are compromised, making it the proper defense against password-based account takeover.
A web administrator is concerned about injection attacks. Which of the following mitigation techniques should the web administrator implement?
Correct Answer:
B
Explanation
Injection attacks succeed when user input flows directly into commands or queries without checking. Parameter validation filters and validates all input before it gets processed, blocking malicious payloads. This stops SQL injection, command injection, and similar attacks that exploit unvetted data. Input encoding and escaping also help, but validation is the primary defense by ensuring only legitimate data enters the system.

FAQ
ITS-110 Exam FAQ
Common questions about the exam itself
What is the target job role for someone with an ITS-110 certification?
ITS-110 prepares you for roles as an IoT Security Practitioner. You will demonstrate the ability to design, implement, operate, and manage secure IoT ecosystems using vendor-neutral security principles.
How is ITS-110 different from the foundational ITP-110 exam?
ITP-110 covers IoT fundamentals like ecosystems, devices, and development. ITS-110 assumes you understand those basics and focuses specifically on security threats and countermeasures across all seven IoT security domains.
How long does it typically take to prepare for ITS-110?
Most candidates prepare for 4 to 8 weeks depending on prior experience with IoT and security concepts. If you already hold ITP-110 or have relevant cybersecurity experience, you may need less time.
Which ITS-110 objective area do candidates find most challenging?
Securing IoT Portals carries the highest weighting at 29% and combines web, cloud, and mobile interface security. It is challenging because it requires understanding threats across multiple platforms and implementing defenses for each.
What is the passing score for ITS-110 and how is it calculated?
You must score either 60% or 61% depending on the specific exam form you receive. The score is calculated as a percentage of your correct answers out of 100 questions.
Can I retake ITS-110 if I do not pass on the first attempt?
Yes. CertNexus allows retakes. You can reschedule your exam through Pearson VUE after your first attempt, though you must purchase a new exam voucher for each attempt.
What should I expect on exam day when taking ITS-110?
The exam takes 120 minutes of testing time. You will answer 100 multiple choice and multiple response questions. The full appointment may be longer when you factor in 5 minutes for agreement review and 5 minutes for the Pearson VUE tutorial.
How long does the CIoTSP certification credential stay valid after passing ITS-110?
CertNexus does not publish specific validity periods for ITS-110. Contact CertNexus directly or check the CertNexus certification page for current renewal and validity requirements.
Is there a prerequisite certification or experience requirement to take ITS-110?
No formal prerequisites exist. However, CertNexus recommends that candidates have foundational knowledge of IoT ecosystems, ideally from the ITP-110 certification or equivalent practical experience.
Where can I take the ITS-110 exam?
You can take ITS-110 online through Pearson OnVUE with live proctoring from anywhere, or in person at any Pearson VUE test centre. Both options use the same question bank and are equivalent in difficulty.
