NEW QUESTION # 39
What type of cyberattack was discussed in the Ukrainian power grid case study?
Answer: D
Explanation:
The Ukrainian power grid cyberattack (2015 and 2016 incidents) is widely documented as a "nation state" attack. It was attributed to a highly skilled, well-resourced group with nation-state backing, and demonstrated the ability to compromise, disrupt, and remotely control industrial systems in critical infrastructure. This attack is discussed in ISA/IEC 62443 training and guidance as an example of advanced persistent threat (APT) activity targeting industrial control systems.
Reference: ISA/IEC 62443-1-1:2007, Section 4.2.6; SANS ICS Analysis of the Ukraine Blackout; US-CERT Alert (IR-ALERT-H-16-056-01).
NEW QUESTION # 40
Authorization (user accounts) must be granted based on which of the following?
Available Choices (select all choices that are correct)
Answer: A
Explanation:
Authorization is the process of granting or denying access to a network resource or function. Authorization (user accounts) must be granted based on specific roles, which are defined as sets of permissions and responsibilities assigned to a user or a group of users. Roles should be based on the principle of least privilege, which means that users should only have the minimum level of access required to perform their tasks. Roles should also be based on the principle of separation of duties, which means that users should not have conflicting or overlapping responsibilities that could compromise the security or integrity of the system.
Authorization based on individual preferences or common needs for large groups is not recommended, as it could lead to excessive or unnecessary access rights, or to inconsistent or conflicting policies. Authorization based on system complexity is also not a good criterion, as it could result in overcomplicated or unclear roles that are difficult to manage or audit. References:

NEW QUESTION # 42
What is one challenge associated with firewalls?
Answer: A
Explanation:
A significant challenge with firewalls in industrial environments is deciding how they should be configured.
The complexity arises from needing to balance operational requirements (such as process data flow) with security needs (such as blocking unauthorized access). Misconfiguration can lead either to security gaps or to unnecessary operational disruptions. Firewalls can filter many types of traffic (not just HTTP) and while updates are important, configuration is the biggest ongoing challenge.

62443-2-1:2009, Section 6.3.2.
