Mixed Deck — All ISA Topics Flashcards

What is the role of a SIEM (Security Information and Event Management) system?

Answer: To correlate and analyze security events in real-time.

A SIEM (Security Information and Event Management) system collects security logs and event data from various sources across an organization's IT infrastructure. Its primary role is to aggregate, correlate, and analyze this data in real-time to detect, prioritize, and respond to security incidents and threats. This provides comprehensive visibility into the security posture and aids in proactive threat management.

What is the relationship between Monitoring & Performance Optimization and ethical professional conduct?

Answer: Ethical considerations are integrated into all aspects of professional practice in this area

Ethical considerations are deeply integrated into Monitoring & Performance Optimization, as professional conduct and integrity underpin all aspects of practice in this field.

Which access control method allows owners to set permissions?

Answer: Discretionary Access Control (DAC)

Discretionary Access Control (DAC) is an access control model where the owner of a resource (e.g., a file or folder) can grant or revoke access permissions to other users. This means the owner has discretion over who can access their resources and what actions they can perform. While flexible, DAC can be less secure than other models as it relies on individual users to manage permissions correctly, potentially leading to misconfigurations.

Which best describes the scope of Disaster Recovery & Backup in professional practice?

Answer: A comprehensive area covering both theoretical foundations and practical applications

Disaster Recovery & Backup encompasses both theoretical foundations and practical applications that are essential to professional practice in this field.

In Information Security Analyst Certification practice, when should a patient's vital signs be reassessed?

Answer: Whenever there is a change in patient condition or as per established protocols

Vital signs should be reassessed whenever there is a change in patient condition, after interventions, or according to established facility protocols to ensure continuous monitoring.

In the context of Information Security Analyst Certification, what does "standard of care" refer to?

Answer: The level of care a reasonably competent professional would provide

Standard of care refers to the level of care that a reasonably competent professional with similar training would provide under similar circumstances.

What is the PRIMARY consideration when performing patient assessment in Information Security Analyst Certification practice?

Answer: Patient safety and accurate data collection

Patient safety and accurate data collection are always the top priorities during any patient assessment to ensure proper diagnosis and treatment planning.

What is 'anti-forensics' and why is it a concern for investigators?

Answer: Techniques used to destroy, hide, or falsify digital evidence to impede investigations

Anti-forensics encompasses techniques like log wiping, timestamp modification, steganography, and file encryption used by attackers to hinder or mislead forensic investigations.

What is the recommended first step when implementing security policies & procedures procedures in Information Security Analyst Certification?

Answer: Assess current practices and identify gaps against established standards

Assessing current practices against established standards identifies specific gaps that need to be addressed, enabling targeted and effective implementation.

What is the most important competency assessed in Disaster Recovery & Backup for professionals in this field?

Answer: Applied knowledge and practical problem-solving ability

Disaster Recovery & Backup assessment focuses on applied knowledge and practical problem-solving ability, ensuring professionals can effectively perform in real-world situations.

What is the recommended approach to staying current in Automation & Scripting?

Answer: Regular professional development, industry publications, and peer collaboration

Staying current in Automation & Scripting requires ongoing professional development, reading industry publications, and collaborating with peers to share knowledge and best practices.

What is the main goal of an Intrusion Detection System (IDS)?

Answer: To detect and alert on potential security breaches.

An Intrusion Detection System (IDS) continuously monitors network traffic or system activities for suspicious patterns or known attack signatures. Its main goal is to identify and alert security personnel to potential security breaches or policy violations. This allows for timely investigation and response, enhancing an organization's overall security posture.

What is the recommended approach to staying current in Disaster Recovery & Backup?

Answer: Regular professional development, industry publications, and peer collaboration

Staying current in Disaster Recovery & Backup requires ongoing professional development, reading industry publications, and collaborating with peers to share knowledge and best practices.

Which component of security architecture ensures systems can recover from failures?

Answer: Fault Tolerance

Fault tolerance is a design principle in security architecture that ensures a system can continue to operate without interruption even if one or more of its components fail. This is achieved by incorporating redundant hardware or software components. By having backup systems or components ready to take over, fault tolerance minimizes downtime and ensures business continuity in the event of a failure, thereby enhancing system reliability and resilience.

Which document defines an organization's approach to risk management?

Answer: Risk Management Framework (RMF)

A Risk Management Framework (RMF) is a structured approach that defines an organization's strategy for managing cybersecurity and privacy risks. It provides a systematic process for identifying, assessing, responding to, and monitoring risks, ensuring that security controls are implemented effectively and continuously managed. This framework guides an organization's overall risk posture and decision-making, aligning security efforts with business objectives.

What common challenge do professionals face when applying Emerging Technologies & Trends principles?

Answer: Balancing theoretical best practices with practical constraints and real-world conditions

Professionals commonly face the challenge of adapting theoretical best practices in Emerging Technologies & Trends to the practical constraints and varying conditions encountered in real-world settings.

In Information Security Analyst Certification, what is the PRIMARY purpose of network segmentation?

Answer: To limit the spread of security breaches and control access between network zones

Network segmentation limits the lateral movement of attackers and controls access between different network zones, reducing the potential impact of security breaches.

Which hashing algorithm is considered secure for current ISA implementations?

Answer: SHA-256 or SHA-3

SHA-256 and SHA-3 are considered cryptographically secure hashing algorithms, while MD5 and SHA-1 have known vulnerabilities.

What is the most important competency assessed in Monitoring & Performance Optimization for professionals in this field?

Answer: Applied knowledge and practical problem-solving ability

Monitoring & Performance Optimization assessment focuses on applied knowledge and practical problem-solving ability, ensuring professionals can effectively perform in real-world situations.

What is the primary goal of the eradication phase in incident response?

Answer: To eliminate the threat from the environment

The eradication phase in incident response focuses on removing the root cause of an incident and eliminating the threat from the environment. This involves actions like isolating infected systems, removing malware, patching vulnerabilities, and disabling compromised accounts. Its primary objective is to ensure the threat is completely gone before recovery begins, preventing further damage or reinfection.
