NEW QUESTION # 15
Which is a common pitfall when initiating a CSMS program?
Available Choices (select all choices that are correct)
Answer: D
Explanation:
"A common pitfall is to attempt to initiate a CSMS program without at least a high-level rationale that relates cyber security to the specific organization and its mission." A CSMS program is a Cybersecurity Management System program that follows the IEC 62443 standards for securing industrial control systems (ICS)1. A common pitfall when initiating a CSMS program is D.
Immediate jump into detailed risk assessment. This is because a detailed risk assessment requires a clear definition of the system under consideration (SuC), the allocation of IACS assets to zones and conduits, and the identification of threats, vulnerabilities, and consequences for each zone and conduit2. These steps are part of the assess phase of the CSMS program, which is the first phase of the security program development process2. However, before starting the assess phase, it is important to have the management team's support to ensure the CSMS program will have sufficient financial and organizational resources to implement necessary actions2. Therefore, jumping into detailed risk assessment without having the management buy-in is a common mistake that can jeopardize the success of the CSMS program.
NEW QUESTION # 16
Which of the following is a recommended default rule for IACS firewalls?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
A recommended default rule for IACS firewalls is to block all traffic by default, and then allow only the necessary and authorized traffic based on the security policy and the zone and conduit model. This is also known as the principle of least privilege, which means granting the minimum access required for a legitimate purpose. Blocking all traffic by default provides a higher level of security and reduces the attack surface of the IACS network. The other choices are not recommended default rules for IACS firewalls, as they may expose the IACS network to unnecessary risks. Allowing all traffic by default would defeat the purpose of a firewall, as it would not filter any malicious or unwanted traffic. Allowing IACS devices to access the Internet would expose them to potential cyber threats, such as malware, phishing, or denial-of-service attacks.
Allowing traffic directly from the IACS network to the enterprise network would bypass the demilitarized zone (DMZ), which is a buffer zone that isolates the IACS network from the enterprise network and hosts services that need to communicate between them. References:

NEW QUESTION # 18
What is a feature of an asymmetric key?
Available Choices (select all choices that are correct)
Answer: D
Explanation:
An asymmetric key is a feature of asymmetric cryptography, also known as public-key cryptography, which is a method of encrypting and decrypting data using two different keys: a public key and a private key. The public key can be shared with anyone, while the private key must be kept secret by the owner. The public key and the private key are mathematically related, but it is computationally infeasible to derive one from the other. Asymmetric cryptography can be used for various purposes, such as digital signatures, key exchange, and encryption. For example, if Alice wants to send a message to Bob, she can use Bob's public key to encrypt the message, and only Bob can decrypt it using his private key. Alternatively, if Bob wants to prove that he is the author of a message, he can use his private key to sign the message, and anyone can verify it using his public key. Asymmetric cryptography has some advantages over symmetric cryptography, which uses the same key for both encryption and decryption. For instance, asymmetric cryptography does not require a secure channel to distribute the keys, and it can provide non-repudiation and authentication.
However, asymmetric cryptography also has some drawbacks, such as higher computational complexity, larger key sizes, and higher network overhead.

NEW QUESTION # 19
What does the abbreviation CSMS round in ISA 62443-2-1 represent?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
The abbreviation CSMS stands for Cyber Security Management System in ISA 62443-2-1. This standard defines the elements necessary to establish a CSMS for industrial automation and control systems (IACS) and provides guidance on how to develop those elements123. A CSMS is a collection of policies, procedures, practices, and personnel that are responsible for ensuring the security of IACS throughout their lifecycle24.
