NEW QUESTION # 22
What is the purpose of ICS-CERT Alerts?
Answer: D
Explanation:
ICS-CERT (Industrial Control Systems Cyber Emergency Response Team) issues alerts to inform critical infrastructure owners and operators about newly discovered vulnerabilities, threats, and mitigation strategies.
"ICS-CERT Alerts provide timely information to critical infrastructure owners and operators concerning current security issues, vulnerabilities, and exploits."
- ICS-CERT Advisory Documentation (now under CISA)
Alerts may be sector-wide or vendor-specific, and are part of the U.S. Department of Homeland Security's proactive cyber defense strategy.
Clarification of Options:
Not specific to the energy sector only (D is too narrow)
Not promotional in nature (eliminates A and B)
References:
ICS-CERT Alert Guidance (now under CISA)

NEW QUESTION # 23
In what step of the development process of the CSMS is "Establish purpose, organizational support, resources, and scope" taken care of?
Answer: D
Explanation:
The first step in the Cyber Security Management System (CSMS) development process is to "Initiate the CSMS program," which involves establishing its purpose, obtaining organizational support, allocating resources, and defining the program's scope. These foundational activities are required to ensure that the program is properly structured and supported before detailed risk assessments or architecture planning are performed.
Reference: ISA/IEC 62443-2-1:2009, Section 5.1 ("Initiate the CSMS program").
NEW QUESTION # 24
Which protocol is commonly used for managing the security of message transmission on the Internet via web browsers?
Answer: C
Explanation:
Transport Layer Security (TLS) is the standard protocol for securing web communications, including HTTP over TLS (HTTPS) in web browsers. TLS provides encryption, authentication, and data integrity, and has replaced SSL as the primary means of securing browser-based communications.
Reference: ISA/IEC 62443-3-3:2013, Section 4.2.3.7 ("Use of TLS for secure communication"); NIST SP
800-52 Rev. 2.
NEW QUESTION # 25
What is a frequent mistake made with cybersecurity management?
Answer: C
Explanation:
One of the most frequent mistakes in cybersecurity management-according to ISA/IEC 62443 guidance-is focusing only on technological solutions and neglecting other critical components such as people, process, and culture. Effective cybersecurity management must include policies, training, incident response, and continual improvement, not just technical controls. This holistic approach is emphasized throughout the standards, particularly in the sections describing CSMS program elements and organizational responsibilities.
Reference: ISA/IEC 62443-2-1:2009, Section 4.2.3 ("Cybersecurity is not just a technology problem"); Section 6.2.4 (Organizational awareness and training).
NEW QUESTION # 26
A company discovers malware on a portable USB device used within their IACS environment. According to the document, which SP Element and controls would be MOST relevant to address this issue?
Answer: D
Explanation:
According to ISA/IEC 62443-2-1, SP Element 4 is focused on system integrity and includes controls such as component hardening and managing dedicated portable media (e.g., USB drives). These controls help mitigate malware risks from removable devices.
"SP Element 4: System integrity. This element includes controls for system hardening and the use of dedicated, protected portable media to reduce infection risk and prevent unauthorized software installation."
- ISA/IEC 62443-2-1:2010, Clause 4.3.4 - SP Elements
While SP Element 7 (Incident Handling) may be involved post-discovery, the primary preventive control is under SP Element 4.
References:
ISA/IEC 62443-2-1:2010 - Clause 4.3.4, Table 2 - SP Element 4
