NEW QUESTION # 180
What are the three main components of the ISASecure Integrated Threat Analysis (ITA) Program?
Available Choices (select all choices that are correct)
Answer: D
Explanation:
The ISASecure Integrated Threat Analysis (ITA) Program is a certification scheme that certifies off-the-shelf automation and control systems to the ISA/IEC 62443 series of standards1. The ITA Program consists of three main components2:
* Software Development Security Assurance (SDSA): This component evaluates the security lifecycle and practices of the product supplier, such as security requirements, design, implementation, verification, and maintenance. The SDSA certification is based on the ISA/IEC 62443-4-1 standard.
* Functional Security Assessment (FSA): This component verifies the security functions and features implemented in the product, such as identification and authentication, access control, encryption, audit logging, and security management. The FSA certification is based on the ISA/IEC 62443-4-2 standard.
* Communications Robustness Testing (CRT): This component tests the resilience of the product against network attacks, such as denial-of-service, fuzzing, spoofing, and replay. The CRT certification is based on the ISA/IEC 62443-4-2 and ISA/IEC 62443-3-3 standards .

NEW QUESTION # 181
Which of the following is an activity that should trigger a review of the CSMS?
Available Choices (select all choices that are correct)
Answer: A,B,D
Explanation:
According to the ISA/IEC 62443-2-1 standard, a review of the CSMS should be triggered by any changes that affect the cybersecurity risk of the industrial automation and control system (IACS), such as new technical controls, organizational restructuring, or security incidents1. Budgeting is not a trigger for CSMS review, unless it impacts the cybersecurity risk level or the CSMS itself2. References: 1: ISA/IEC 62443-2-1:2010, Section 4.3.3.3 2: A Practical Approach to Adopting the IEC 62443 Standards, ISAGCA Blog3
NEW QUESTION # 182
Which statement is TRUE reqardinq application of patches in an IACS environment?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
Patches are software updates that fix bugs, vulnerabilities, or improve performance or functionality. Patches are important for maintaining the security and reliability of an IACS environment, but they also pose some challenges and risks. Applying patches in an IACS environment is not as simple as in an IT environment, because patches may affect the availability, integrity, or safety of the IACS. Therefore, patches should not be applied blindly or automatically, but based on the organization's risk assessment. The risk assessment should consider the following factors: 1
* The severity and likelihood of the vulnerability that the patch addresses
* The impact of the patch on the IACS functionality and performance
* The compatibility of the patch with the IACS components and configuration
* The availability of a backup or recovery plan in case the patch fails or causes problems
* The testing and validation of the patch before applying it to the production system
* The communication and coordination with the stakeholders involved in the patching process
* The documentation and auditing of the patching activities and results References: ISA TR62443-2-3 - Security for industrial automation and control systems, Part 2-3: Patch management in the IACS environment
NEW QUESTION # 183
Under User Access Control (SP Element 6), which of the following is included in USER 1 - Identification and Authentication?
Answer: D
Explanation:
SP Element 6 in ISA/IEC 62443-2-1 covers User Access Control. Within this, USER 1 - Identification and Authentication includes controls such as:
Unique user identification
Password and credential management
Authentication mechanisms
"USER 1 defines policies for individual user identification and password protection to enforce accountability and prevent unauthorized access."
- ISA/IEC 62443-2-1:2010, Clause 4.3.4 - SP Element 6
"Password protection" is a core component of this control, while other options (like incident handling or backup) fall under different SP elements.
