Question No: 1

MultipleChoice

A security manager has decided to form a special group of analysts who participate in both penetration testing and defending the company's network infrastructure during exercises. Which option best teams should the group form in order to achieve this goal?

Options

ABlue team

BPurple team

CRed team

DGreen team

Answer
BExplanation

Comprehensive and Detailed Explanation From Exact Extract:

A purple team is specifically defined as a collaborative approach that combines the offensive focus of the red team (penetration testing/adversary emulation) with the defensive focus of the blue team (detection/response and defense). That matches the scenario: analysts participate in both pen testing and defending during exercises.

Exact extract (All-in-One Exam Guide):

''purple team A collaborative approach that combines the 'red team' and 'blue team.' The red team attempts to breach the organization's defenses, while the blue team responds to the simulated attacks from the red team.''

The Sybex Practice Tests also reinforce this definition:

Exact extract (Sybex Practice Tests):

''...the purple team combines elements of the red team and blue team.''

Reference (CompTIA CySA+ CS0-003 documents / study guides used):

Mya Heath et al., CompTIA CySA+ All-in-One Exam Guide (CS0-003): purple team combines red + blue

Chapple/Seidl, CompTIA CySA+ Practice Tests (CS0-003): purple team combines red + blue

MultipleChoice

The Chief Information Security Officer for an organization recently received approval to install a new EDR solution. Following the installation, the number of alerts that require remediation by an analyst has tripled. Which option best should the organization utilize to best centralize the workload for the internal security team? (Select two).

Options

ASOAR

BSIEM

CMSP

DNGFW

EXDR

FDLP

Answer
A, BExplanation

SOAR (Security Orchestration, Automation and Response) and SIEM (Security Information and Event Management) are solutions that can help centralize the workload for the internal security team by collecting, correlating, and analyzing alerts from different sources, such as EDR. SOAR can also automate and streamline incident response workflows, while SIEM can provide dashboards and reports for security monitoring and compliance. Reference: What is EDR?

Question No: 3

MultipleChoice

A user reports a message as suspicious to the IT security team. An analyst reviews the message and notices that the following text string becomes a hyperlink in an email:

%77%77%77%2e%69%63%65%2d%70%74%69%63%2e%63%6f%6d

Which of the following would most likely explain this behavior?

Options

AThe string contains obfuscated JavaScript shellcode

BThe text is encoded and designed to bypass spam filters.

CThe email client has a parsing error elsewhere in the message.

DThe sandboxed PC used for testing has non-default configurations.

Answer
BExplanation

The string provided is percent-encoded text, commonly used to obfuscate URLs. When decoded, it translates to www.ice-ptic.com. Such encoding is used to bypass email security filters and spam detectors, making the malicious link appear as benign or unreadable to the automated scanners.

Option A is incorrect: The string does not match JavaScript shellcode formats.

Option C and D are unlikely and unrelated to the actual behavior.

Question No: 4

MultipleChoice

The Chief Executive Officer (CEO) has notified that a confidential trade secret has been compromised. Which of the following communication plans should the CEO initiate?

Options

AAlert department managers to speak privately with affected staff.

BSchedule a press release to inform other service provider customers of the compromise.

CDisclose to all affected parties in the Chief Operating Officer for discussion and resolution.

DVerify legal notification requirements of PII and SPII in the legal and human resource departments.

Answer
AExplanation

The CEO should initiate an alert to department managers to speak privately with affected staff. This is because the trade secret is confidential and should not be disclosed to the public. Additionally, the CEO should verify legal notification requirements of PII and SPII in the legal and human resource departments to ensure compliance with data protection laws.

Question No: 5

MultipleChoice

A cybersecurity analyst has been assigned to the threat-hunting team to create a dynamic detection strategy based on behavioral analysis and attack patterns. Which of the following best describes what the analyst will be creating?

Options

ABots

BloCs

CTTPs

DSignatures

Answer
CExplanation

The analyst will be creating TTPs (Tactics, Techniques, and Procedures). TTPs describe the behavior, methods, and patterns used by attackers during a cyber attack. By focusing on TTPs, the analyst can develop a dynamic detection strategy that identifies malicious activities based on the observed behavior and patterns, rather than relying on static indicators like signatures or IOCs (Indicators of Compromise).

Question No: 6

MultipleChoice

An end-of-life date was announced for a widely used OS. A business-critical function is performed by some machinery that is controlled by a PC, which is utilizing the OS that is approaching the end-of- life date. Which of the following best describes a security analyst's concern?

Options

AAny discovered vulnerabilities will not be remediated.

BAn outage of machinery would cost the organization money.

CSupport will not be available for the critical machinery

DThere are no compensating controls in place for the OS.

Answer
AExplanation

A security analyst's concern is that any discovered vulnerabilities in the OS that is approaching the end-of-life date will not be remediated by the vendor, leaving the system exposed to potential attacks. The other options are not directly related to the security analyst's role or responsibility.

Question No: 7

MultipleChoice

A security team identified several rogue Wi-Fi access points during the most recent network scan. The network scans occur once per quarter. Which of the following controls would best all ow the organization to identity rogue devices more quickly?

Options

AImplement a continuous monitoring policy.

BImplement a BYOD policy.

CImplement a portable wireless scanning policy.

DChange the frequency of network scans to once per month.

Answer
AExplanation

The best control to allow the organization to identify rogue devices more quickly is

A) Implement a continuous monitoring policy. A continuous monitoring policy is a set of procedures and tools that enable an organization to detect and respond to unauthorized or anomalous activities on its network in real time or near real time. A continuous monitoring policy can help identify rogue access points as soon as they appear on the network, rather than waiting for quarterly or monthly scans.A continuous monitoring policy can also help improve the overall security posture and compliance of the organization by providing timely and accurate information about its network assets, vulnerabilities, threats, and incidents1.

Question No: 8

MultipleChoice

An employee is no longer able to log in to an account after updating a browser. The employee usually has several tabs open in the browser. Which of the following attacks was most likely performed?

Options

ARFI

BLFI

CCSRF

DXSS

Answer
CExplanation

The most likely attack that was performed is CSRF (Cross-Site Request Forgery). This is an attack that forces a user to execute unwanted actions on a web application in which they are currently authenticated1. If the user has several tabs open in the browser, one of them might contain a malicious link or form that sends a request to the web application to change the user's password, email address, or other account settings. The web application will not be able to distinguish between the legitimate requests made by the user and the forged requests made by the attacker. As a result, the user will lose access to their account.

To prevent CSRF attacks, web applications should implement some form of anti-CSRF tokens or other mechanisms that validate the origin and integrity of the requests2. These tokens are unique and unpredictable values that are generated by the server and embedded in the forms or URLs that perform state-changing actions. The server will then verify that the token received from the client matches the token stored on the server before processing the request. This way, an attacker cannot forge a valid request without knowing the token value.

Some other possible attacks that are not relevant to this scenario are:

RFI (Remote File Inclusion) is an attack that allows an attacker to execute malicious code on a web server by including a remote file in a script. This attack does not affect the user's browser or account settings.

LFI (Local File Inclusion) is an attack that allows an attacker to read or execute local files on a web server by manipulating the input parameters of a script. This attack does not affect the user's browser or account settings.

XSS (Cross-Site Scripting) is an attack that injects malicious code into a web page that is then executed by the user's browser. This attack can affect the user's browser or account settings, but it requires the user to visit a compromised web page or click on a malicious link. It does not depend on having several tabs open in the browser.

Question No: 9

MultipleChoice

A company brings in a consultant to make improvements to its website. After the consultant leaves. a web developer notices unusual activity on the website and submits a suspicious file containing the following code to the security team:

Which of the following did the consultant do?

Implanted a backdoor

Implemented privilege escalation

Implemented clickjacking

Patched the web server

Options

AImplanted a backdoor.
A backdoor is a method that allows an unauthorized user to access a system or network without the permission or knowledge of the owner. A backdoor can be installed by exploiting a software vulnerability, by using malware, or by physically modifying the hardware or firmware of the device. A backdoor can be used for various malicious purposes, such as stealing data, installing malware, executing commands, or taking control of the system.
In this case, the consultant implanted a backdoor in the website by using an HTML and PHP code snippet that displays an image of a shutdown button and an alert message that says ''Exit''. However, the code also echoes the remote address of the server, which means that it sends the IP address of the visitor to the attacker. This way, the attacker can identify and target the visitors of the website and use their IP addresses to launch further attacks or gain access to their devices.
The code snippet is an example of a clickjacking attack, which is a type of interface-based attack that tricks a user into clicking on a hidden or disguised element on a webpage. However, clickjacking is not the main goal of the consultant, but rather a means to implant the backdoor. Therefore, option C is incorrect.
Option B is also incorrect because privilege escalation is an attack technique that allows an attacker to gain higher or more permissions than they are supposed to have on a system or network. Privilege escalation can be achieved by exploiting a software vulnerability, by using malware, or by abusing misconfigurations or weak access controls. However, there is no evidence that the consultant implemented privilege escalation on the website or gained any elevated privileges.
Option D is also incorrect because patching is a process of applying updates to software to fix errors, improve performance, or enhance security. Patching can prevent or mitigate various types of attacks, such as exploits, malware infections, or denial-of-service attacks. However, there is no indication that the consultant patched the web server or improved its security in any way.

Question No: 10

MultipleChoice

The Chief Information Security Officer (CISO) wants the same level of security to be present whether a remote worker logs in at home or at a coffee shop. Which of the following should be recommended as a starting point?

Options

ANon-persistent virtual desktop infrastructures (VDI)

BPasswordless authentication

CStandard-issue laptops

DServerless workloads

Answer
AExplanation

Non-persistent Virtual Desktop Infrastructure (VDI) is the best solution because:

Users access a centrally managed, secure virtual desktop regardless of location.

No data is stored locally, preventing data theft on compromised devices.

Each session is reset upon logout, eliminating malware persistence.

Why Not Other Options?

B (Passwordless authentication) Improves security but does not ensure the same security level across different locations.

C (Standard-issue laptops) Helps with consistency but does not protect against untrusted networks.

D (Serverless workloads) Focuses on application infrastructure, not user security.

Question No: 11

MultipleChoice

A vulnerability scan shows several vulnerabilities. At the same time, a zero-day vulnerability with a CVSS score of 10 has been identified on a web server. Which of the following actions should the security analyst take first?

Options

AContact the web systems administrator and request that they shut down the asset.

BMonitor the patch releases for all items and escalate patching to the appropriate team.

CRun the vulnerability scan again to verify the presence of the critical finding and the zero-day vulnerability.

DForward the advisory to the web security team and initiate the prioritization strategy for the other vulnerabilities.

Answer
AExplanation

A CVSS 10 vulnerability represents a critical security risk, often leading to remote code execution or complete system compromise.

Option A (Shut down the asset) is the best immediate containment action for preventing exploitation.

Option B (Monitor patches) is important but should be done after containment.

Option C (Rescanning) is unnecessary when a high-confidence security advisory has been issued.

Option D (Forwarding advisory) is good practice but does not immediately mitigate the threat.

A company is aiming to test a new incident response plan. The management team has made it clear that the initial test should have no impact on the environment. The company has limited

resources to support testing. Which of the following exercises would be the best approach?

Options

ATabletop scenarios

BCapture the flag

CRed team vs. blue team

DUnknown-environment penetration test

Answer
AExplanation

A tabletop scenario is an informal, discussion-based session in which a team discusses their roles and responses during an emergency, walking through one or more example scenarios. A tabletop scenario is the best approach for a company that wants to test a new incident response plan without impacting the environment or using many resources. A tabletop scenario can help the company identify strengths and weaknesses in their plan, clarify roles and responsibilities, and improve communication and coordination among team members. The other options are more intensive and disruptive exercises that involve simulating a real incident or attack.

Which of the following is the best reason why organizations need operational security controls?

Options

ATo supplement areas that other controls cannot address

BTo limit physical access to areas that contain sensitive data

CTo assess compliance automatically against a secure baseline

DTo prevent disclosure by potential insider threats

Answer
AExplanation

Operational security controls are security measures that are implemented and executed by people rather than by systems. Operational security controls are needed to supplement areas that other controls, such as technical or physical controls, cannot address. For example, operational security controls can include policies, procedures, training, awareness, audits, reviews, testing, etc. These controls can help ensure that employees follow best practices, comply with regulations, detect and report incidents, and respond to emergencies. The other options are not specific to operational security controls or are too narrow in scope.
