CYSA, Top Exam Questions and
answers, 100% Accurate. Graded A+
In the NIST Special Publication 800-53 Security and Privacy Controls for Federal Information Systems and
Organizations, security controls are categories into one of 18 families. What does a category of RA
mean?
Regular Access
Regulatory Administrative
Risk Assessment
Reduced Administration - ✔✔-Risk Assessment
Which security control functional type is used to identify and record any attempted or successful
intrusion?
Detective Control
Corrective Control
Preventative Control
Administrative Control - ✔✔-Detective Control
A detective control is a a type of security control that acts during an incident to identify or record that it
is happening. A detective control operates during the progress of an attack. Examples include logs and
security cameras which are used to maintain a record of actions taken by an attacker.
Which of the following automatically combines multiple disparate sources of information together to
form a complete picture of events for analysts to use during an incident response or when conducting
proactive threat hunting?
Machine Learning
Deep Learning
,Data Enrichment
Continuous integration - ✔✔-Data Enrichment
When data enrichment is occurring, it could combine a threat intelligence feed with a log of NetFlow.
This will allow the analyst to know if an IP address of interest is actually associated with a known APT.
Machine learning and deep learning are forms of artificial intelligence that may be used to conduct data
enrichment activities, but individually they are not sufficient to answer this question. Continuous
integration is a software development method in which code updates are tested and committed to a
development or build server/code repository rapidly, and is unrelated to this question.
In which phase of the security intelligence cycle is input collected from intelligence producers and
consumers to improve the implementation of intelligence requirements?
Feedback
Analysis
Dissemination
Collection - ✔✔-Feedback
The final phase of the security intelligence cycle is feedback and review, which utilizes the input of both
intelligence producers and intelligence consumers. The goal of this phase is to improve the
implementation of the requirements, collection, analysis, and dissemination phases as the life cycle is
developed.
Which of the following is an example of an open-source intelligence feed?
IBM X-Force Exchange
Recorded Future
FireEye
Malware Information Sharing Project - ✔✔-Malware Information Sharing Project
The Malware Information Sharing Project, or MISP, is an open-source intelligence feed. Other popular
open-source intelligence feeds are AT&T Security (Alien Vault Open Threat Exchange), Spamhaus, SANS
, ISC Suspicious Domains, VirusTotal, and NCAS by US0CERT. Closed-source or proprietary intelligence
sources include IBM X-Force Exchange, Recorded Future, and FireEye.
Which type of threat will patches NOT effectively combat as a security control?
Zero-day attacks
Known vulnerabilities
Discovered software bugs
Malware with defined indicators of compromise - ✔✔-Zero-day Attacks
Zero-day attacks have no known fix, so patches will not correct them. A zero-day vulnerability is a
computer-software vulnerability that is unknown to, or unaddressed by, those who should be interested
in mitigating the vulnerability (including the vendor of the target software). If a discovered software bug
or known vulnerability is found, there is normally a patch or mitigation available for it. If a piece of
malware has well-defined indicators of compromise, a patch or signature can be created to defend
against it, as well.
Which analysis framework provides the most explicit detail regarding how to mitigate or detect a given
threat?
Diamond Model of Intrusion Analysis
MITRE ATT&CK framework
OpenIOC
Lockheed Martin cyber kill chain - ✔✔-MITRE ATT&CK framework
The MITRE ATT&CK framework provides explicit pseudo-code examples for how to detect or mitigate a
given threat within a network and ties specific behaviors back to individual actors. The Diamond Model
provides an excellent methodology for communicating cyber events and allowing an analyst to implicitly
derive mitigation strategies. The Lockheed Martin cyber kill chain provides a general life cycle
description of how attacks occur but does not deal with the specifics of how to mitigate. OpenIOC
contains a depth of research on APTs but does not integrate the detections and mitigation strategy.
