NEW QUESTION # 23
What is a commonly used protocol for managing secure data transmission over a Virtual Private Network (VPN)?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
IPSec is a commonly used protocol for managing secure data transmission over a VPN. IPSec stands for Internet Protocol Security and it is a set of standards that define how to encrypt and authenticate data packets that travel between two or more devices over an IP network. IPSec can operate in two modes: transport mode and tunnel mode. In transport mode, IPSec only encrypts the payload of the IP packet, leaving the header intact. In tunnel mode, IPSec encrypts the entire IP packet and encapsulates it in a new IP header. Tunnel mode is more secure and more suitable for VPNs, as it can protect the original source and destination addresses of the IP packet from eavesdropping or spoofing. IPSec uses two main protocols to provide security services: Authentication Header (AH) and Encapsulating Security Payload (ESP). AH provides data integrity and source authentication, but not confidentiality. ESP provides data integrity, source authentication, and confidentiality. IPSec also uses two protocols to establish and manage security associations (SAs), which are the parameters and keys used for encryption and authentication: Internet Key Exchange (IKE) and Internet Security Association and Key Management Protocol (ISAKMP). IKE is a protocol that negotiates and exchanges cryptographic keys between two devices. ISAKMP is a protocol that defines the format and structure of the messages used for key exchange and SA management.

NEW QUESTION # 24
Which NIST Special Publication focuses specifically on securing Industrial Control Systems (ICS)?
Answer: A
Explanation:
NIST SP 800-82 is the definitive guidance for securing Industrial Control Systems (ICS), including SCADA, DCS, and PLC-based systems.
"NIST Special Publication 800-82 provides guidance on how to secure ICS, including supervisory control and data acquisition (SCADA) systems, distributed control systems (DCS), and other control system configurations."
- NIST SP 800-82 Rev. 2, Executive Summary
While:
SP 800-30 focuses on risk assessment
SP 800-53 provides general security controls for federal systems
SP 800-171 targets controlled unclassified information (CUI) in non-federal systems Only SP 800-82 specifically addresses ICS/OT environments.

NEW QUESTION # 25
In the context of global frameworks, what does the acronym SDO stand for?
Answer: D
Explanation:
In the context of international standards and frameworks, SDO stands for "Standards Development Organization." SDOs are organizations like ISA, IEC, ISO, and NIST, which are responsible for developing, maintaining, and publishing standards used globally for industrial cybersecurity and other domains.
Reference: ISA/IEC 62443-1-1:2007, Section 3.1 (Abbreviations and terms); official definitions in standards literature.

NEW QUESTION # 27
What is defined as the hardware and software components of an IACS?
Available Choices (select all choices that are correct)
Answer: C
Explanation:
According to the ISA/IEC 62443-1-1 standard, an industrial automation and control system (IACS) is defined as a collection of personnel, hardware, and software that can affect or influence the safe, secure, and reliable operation of an industrial process. The hardware and software components of an IACS include the control system, which is the combination of control devices, networks, and applications that perform the control functions for the industrial process. The control system may consist of various types of devices, such as distributed control systems (DCS), programmable logic controllers (PLC), supervisory control and data acquisition (SCADA) systems, human-machine interfaces (HMI), remote terminal units (RTU), intelligent electronic devices (IED), sensors, actuators, and other field devices. The control system may also use commercial off-the-shelf (COTS) software and hardware, such as operating systems, databases, firewalls, routers, switches, and servers, to support the control functions and communication.
