NEW QUESTION # 133
Which service does an Intrusion Detection System (IDS) provide?
Answer: C
Explanation:
An Intrusion Detection System (IDS) is a passive monitoring tool that detects unauthorized or malicious activity in networked systems. It does not block traffic (like an IPS), but rather alerts administrators to potential breaches.
"An IDS monitors network or system activities for malicious actions or policy violations and produces alerts or logs for analysis."
- ISA/IEC 62443-3-3:2013, SR 3.2 - Detection of Security Events
It's a core component of security monitoring and response - often paired with an Incident Response Plan (IRP) as defined in ISA/IEC 62443-2-1.
Clarification of Options:
Option A is metaphorical and not technically accurate.
Option B is false; IDS does not protect against all vulnerabilities.
Option C is incorrect; IDS does not block, only detects.
Option D is correct - it detects unauthorized access or misuse.

NEW QUESTION # 134
What type of security level defines what a component or system is capable of meeting?
Available Choices (select all choices that are correct)
Answer: B
Explanation:
According to the IEC 62443 standard, a capability security level (SL-C) is defined as "the security level that a component or system is capable of meeting when it is properly configured and protected by an appropriate set of security countermeasures" 1. A component or system can have different SL-Cs for different security requirements, depending on its design and implementation. The SL-C is determined by testing the component or system against a set of security test cases that correspond to the security requirements. The SL-C is not dependent on the actual operational environment orconfiguration of the component or system, but rather on its inherent capabilities. References:

NEW QUESTION # 135
According to the scheme for cybersecurity profiles, which of the following is true about ISA/IEC 62443 security requirements when creating a security profile?
Answer: D
Explanation:
ISA/IEC TR 62443-1-5 describes how to create cybersecurity profiles tailored to specific sectors or applications. While the core structure of security requirements remains, modifications are allowed to align with sector-specific needs or regulatory requirements.
"Profiles can tailor existing security requirements to better fit sector-specific needs. Modification of requirement wording, priority, or applicability may be made in line with risk tolerance and context."
- ISA/IEC TR 62443-1-5:2018, Clause 5.3 - Profile Customization
This enables flexibility while retaining consistency across profiles.
