ICS-SCADA PDF 75 Questions

What type of communication protocol does Modbus RTU use?

  1. UDP
  2. ICMP
  3. Serial
  4. SSTP

Answer(s): C

Explanation:

Modbus RTU (Remote Terminal Unit) is a communication protocol based on a master-slave architecture that uses serial communication. It is one of the earliest communication protocols developed for devices connected over serial lines. Modbus RTU packets are transmitted in a binary format over serial lines such as RS-485 or RS-232.


Reference:

Modbus Organization, "MODBUS over Serial Line Specification and Implementation Guide V1.02".



Which of the ICS/SCADA generations is considered monolithic?

  1. Second
  2. First
  3. Fourth
  4. Third

Answer(s): B

Explanation:

The first generation of ICS/SCADA systems is considered monolithic, primarily characterized by standalone systems that had no external communications or connectivity with other systems. These systems were typically fully self-contained, with all components hard-wired together, and operations were managed without any networked interaction.


Reference:

U.S. Department of Homeland Security, "Recommended Practice: Improving Industrial Control System Cybersecurity with Defense-in-Depth Strategies".



Which of the following components is not part of the Authentication Header (AH)?

  1. Replay
  2. Authentication
  3. Confidentiality
  4. Integrity

Answer(s): C

Explanation:

The Authentication Header (AH) is a component of the IPsec protocol suite that provides authentication and integrity to the communications. AH ensures that the contents of the communications have not been altered in transit (integrity) and verifies the sending and receiving parties (authentication). However, AH does not provide confidentiality, which would involve encrypting the payload data. Confidentiality is provided by the Encapsulating Security Payload (ESP), another component of IPsec.


Reference:

RFC 4302, "IP Authentication Header".



How many main score areas are there in the CVSS?2

  1. 2
  2. 4
  3. 3
  4. None of these

Answer(s): C

Explanation:

The Common Vulnerability Scoring System (CVSS) is a framework for rating the severity of security vulnerabilities. CVSS provides three main score areas: Base, Temporal, and Environmental. Base Score evaluates the intrinsic qualities of a vulnerability. Temporal Score reflects the characteristics of a vulnerability that change over time. Environmental Score considers the specific impact of the vulnerability on a particular organization, tailoring the Base and Temporal scores according to the importance of the affected IT asset.


Reference:

FIRST, "Common Vulnerability Scoring System v3.1: Specification Document".



Which of the following is NOT an exploit tool?

  1. Canvas
  2. Core Impact
  3. Metasploit
  4. Nessus

Answer(s): D

Explanation:

Among the options listed, Nessus is primarily a vulnerability assessment tool, not an exploit tool. It is used to scan systems, networks, and applications to identify vulnerabilities but does not exploit them. On the other hand, Canvas, Core Impact, and Metasploit are exploit tools designed to actually perform attacks (safely and legally) to demonstrate the impact of vulnerabilities.


Reference:

Tenable, Inc., "Nessus FAQs".

there is an incorrect word in the problem statement. for example, in question 1, there is the word "speci c". this is "specific. in the other question, there is the word "noti cation". this is "notification. these mistakes make this site difficult for me to use.

q47: intrusion prevention system is the correct answer, not patch management. by definition, there are no patches available for a zero-day vulnerability. the way to prevent an attacker from exploiting a zero-day vulnerability is to use an ips.
