NEW QUESTION # 138
Which protocol is commonly used for managing the security of message transmission on the Internet via web browsers?
Answer: A
Explanation:
Transport Layer Security (TLS) is the primary cryptographic protocol used to secure web-based communications such as HTTPS in web browsers.
From ISA/IEC 62443-3-3 (System Security Requirements and Security Levels), Annex B:
"TLS provides confidentiality, integrity, and authentication for communications over untrusted networks. It is commonly used to secure HTTPS, SMTP, and other application protocols." TLS superseded SSL and is the backbone of secure data transmission over the Internet.
Incorrect Options:
B). L2TP - Used for VPNs; not typically browser-related.
C). PPTP - An older VPN protocol, not used for browser encryption.
D). IPsec - Used to secure IP traffic at the network layer; not directly used in browser-based communication.

NEW QUESTION # 139
Which organization manages the ISASecure conformance certification program?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
The ISASecure conformance certification program is managed by the Security Compliance Institute (ISCI), a non-profit organization established in 2007 by a group of industry stakeholders, including end users, suppliers, and integrators. ISCI's mission is to provide a common industry-accepted set of device and process requirements that drive device security, simplifying procurement for asset owners and device assurance for equipment vendors12.

NEW QUESTION # 141
A national standards body wants to represent its country's interests at an international level and adopt global standards locally. What role does this organization fulfill?
Answer: A
Explanation:
ISA/IEC 62443 is developed within the international standards system, where national participation is coordinated through National Standardization Bodies (NSBs). These organizations represent their country's interests in international standards committees and manage the adoption of international standards at the national level.
Step 1: Role of a National Standardization Body
An NSB acts as the official representative of a country within international standards organizations such as IEC and ISO. It coordinates national input, votes on standards, and nominates experts to technical committees.
Step 2: Adoption of international standards
NSBs are responsible for adopting international standards as national standards, often with minimal or no modification. This enables consistent global alignment while supporting local implementation.
Step 3: Why other options are incorrect
* Global SDOs develop standards internationally but do not represent individual countries.
* Regulatory agencies enforce laws, not standards.
* Industry consortia represent private-sector interests, not national positions.
Thus, the correct role is National Standardization Body.
NEW QUESTION # 142
Electronic security, as defined in ANSI/ISA-99.00.01:2007. includes which of the following?
Available Choices (select all choices that are correct)
Answer: B,C
Explanation:
In ANSI/ISA-99.00.01:2007, which is part of the ISA/IEC 62443 standards, electronic security encompasses both the technical and human aspects of cybersecurity within industrial automated and control systems (IACS). Option B correctly highlights components such as computers, networks, operating systems, applications, and other programmable configurable components which are intrinsic to the system's electronic security framework. Option C is also correct as it includes the personnel, policies, and procedures which play a crucial role in securing these systems. This emphasizes that security is not only about the technological solutions but also about managing human elements and organizational processes effectively.
ISA/IEC 62443 Cybersecurity Fundamentals References:
* ISA/IEC 62443 standards focus on the holistic nature of security which is clearly supported by including both the technological (Option B) and human elements (Option C) in the definition of electronic security.
