NEW QUESTION 213
Two organizations are assessing a partnership to exchange security information and share resources in case an incident occurs. The assessment is in the pre-contract stage, and no detailed definitions have been made by management. Which of the following is the best artifact to formalize the agreement at the current stage?

MOU

SLA

SLO

NDA

A Memorandum of Understanding (MOU) is used during the early stages of a partnership to document the intent of the parties to cooperate and outline high-level roles, expectations, and objectives. It is appropriate when detailed contractual terms, service commitments, and operational definitions have not yet been established.

NEW QUESTION 214
Which of the following in the digital forensics process is considered a critical activity that often includes a graphical representation of process and operating system events?

Registry editing

Network mapping

Timeline analysis

Write blocking

Timeline analysis in digital forensics involves creating a chronological sequence of events based on system logs, file changes, and other forensic data. This process often uses graphical representations to illustrate and analyze how an incident unfolded over time, making it easier to identify key events and potential indicators of compromise. This approach is highlighted in CompTIA Cybersecurity Analyst (CySA+) practices as crucial for understanding the scope and sequence of a security incident. The other options do not involve chronological or graphical analysis to the extent that timeline analysis does.

NEW QUESTION 215
A security analyst has just received an incident ticket regarding a ransomware attack. Which of the following would most likely help an analyst properly triage the ticket?

Incident response plan

Lessons learned

Playbook

Tabletop exercise

A playbook provides a step-by-step guide for handling specific types of incidents like ransomware, making it invaluable during triage. It outlines predefined procedures, aiding consistent and fast decision-making.

NEW QUESTION 216
A systems administrator is reviewing the output of a vulnerability scan.
INSTRUCTIONS
Review the information in each tab.
Based on the organization’s environment architecture and remediation standards, select the server to be patched within 14 days and select the appropriate technique and mitigation.

see the explanation for step by step solution.
Explanation:
Step 1: Reviewing the Vulnerability Remediation Timeframes
The remediation standards require servers to be patched based on their CVSS score:
* CVSS > 9.0: Patch within 7 days
* CVSS 7.9 – 9.0: Patch within 14 days
* CVSS 5.0 – 7.9: Patch within 30 days
* CVSS 0 – 5.0: Patch within 60 days
Step 2: Analyzing the Output Tab
From the Output tab:
* Server 192.168.76.5 has a CVSS score of 9.2 for an unsupported Microsoft IIS version, indicating a critical vulnerability requiring a patch within 7 days.
* Server 192.168.76.6 has a CVSS score of 7.4 for a missing secure attribute on HTTPS cookies, which falls in the 5.0 – 7.9 range, requiring a patch within 30 days.
Since the question asks for the server to be patched within 14 days, we need to focus on servers with CVSS
7.9 – 9.0:
* None of the servers have a CVSS score that falls precisely in the 7.9 – 9.0 range.
* However, 192.168.76.5, with a CVSS score of 9.2, has a vulnerability that necessitates a quick response and fits as it must be patched within the shortest timeframe (7 days, which includes 14 days).
The server that fits within a 14-day urgency, based on standard practices, would be 192.168.76.5.
Step 3: Reviewing the Environment Tab
The Environment Tab provides additional context for 192.168.76.5:
* It’s in the dev environment, which is internal and not publicly accessible.
* MFA is required, indicating security measures are already present.
Step 4: Selecting the Appropriate Technique and Mitigation
For 192.168.76.5, with the Microsoft IIS unsupported version:
* Patch; upgrade IIS to the current release is the most suitable option, as upgrading IIS will resolve the unsupported software vulnerability by bringing it up-to-date with supported versions.
* This technique addresses the root cause, which is the unpatched, outdated software.
Summary
* Server to be patched within 14 calendar days: 192.168.76.5
* Appropriate technique and mitigation: Patch; upgrade IIS to the current release This approach ensures that the most critical vulnerabilities are addressed promptly, maintaining security compliance.

NEW QUESTION 217
The security analyst received the monthly vulnerability report. The following findings were included in the report
* Five of the systems only required a reboot to finalize the patch application.
* Two of the servers are running outdated operating systems and cannot be patched The analyst determines that the only way to ensure these servers cannot be compromised is to isolate them. Which of the following approaches will best minimize the risk of the outdated servers being compromised?

Compensating controls

Due diligence

Maintenance windows

Passive discovery

Compensating controls are the best approach to minimize the risk of the outdated servers being compromised, as they can provide an alternative or additional layer of security when the primary control is not feasible or effective. Compensating controls are security measures that are implemented to mitigate the risk of a vulnerability or an attack when the primary control is not feasible or effective. For example, if the servers are running outdated operating systems and cannot be patched, a compensating control could be to isolate them from the rest of the network, or to implement a firewall or an intrusion prevention system to monitor and block any malicious traffic to or from the servers. Compensating controls can help reduce the likelihood or impact of an exploit, but they do not eliminate the risk completely. Therefore, the security analyst should also consider upgrading or replacing the outdated servers as soon as possible.

NEW QUESTION 218
An analyst is evaluating a vulnerability management dashboard. The analyst sees that a previously remediated vulnerability has reappeared on a database server. Which of the following is the most likely cause?

The finding is a false positive and should be ignored.

A rollback had been executed on the instance.

The vulnerability scanner was configured without credentials.

The vulnerability management software needs to be updated.

A rollback had been executed on the instance. If a database server is restored to a previous state, it may reintroduce a vulnerability that was previously fixed. This can happen due to backup and recovery operations, configuration changes, or software updates. A rollback can undo the patching or mitigation actions that were applied to remediate the vulnerability. References: Vulnerability Remediation: It’s Not Just Patching, Section:
The Remediation Process; Vulnerability assessment for SQL Server, Section: Remediation

NEW QUESTION 219
The threat intelligence team is using the MITRE ATT & CK framework to map threat actors’ TTPs to the team’s internal reference library. Which of the following best describes the reason visualization and stage alignment are helpful for the incident response team?

Having a common framework provides structure for relaying the known indicators of concern to the security monitoring team.

Knowing the attack stage helps the incident response team determine how to structure custom SIEM alerts to detect security events of interest.

A visual mapping helps the incident response team identify the stage and relevant TTPs faster than a white paper for each threat actor.

Aligning an action to a specific stage in an incident allows the incident response team to better define intent and anticipate the next action.

The correct answer is D because MITRE ATT & CK maps adversary tactics, techniques, and procedures to stages or tactical goals of an attack. When the incident response team can align observed activity to a specific ATT & CK stage, the team can better understand the attacker’s intent, determine what has likely already happened, and anticipate what the attacker may try next.
The CySA+ All-in-One guide explains that attack frameworks break a cyberattack “from initial reconnaissance to final exfiltration of data” into steps or phases. It also states that studying attacker TTPs helps analysts “better anticipate and prepare for potential attacks” and develop stronger incident response plans.
The guide further explains that MITRE ATT & CK provides a structured methodology for modeling and understanding attacker TTPs, with tactics representing high-level goals and techniques representing the methods attackers use to achieve those goals.
It also states that in incident response, analysts can map observed attacker behavior to the appropriate ATT & CK technique to better understand the attacker’s goals and motivations, identify other potentially compromised areas, and prioritize remediation.
Why the other options are incorrect:
A is partially true, but it focuses more on communicating indicators to monitoring teams, not on why stage alignment helps incident responders.
B is too narrow because it focuses on SIEM alert creation rather than incident response decision-making.
C is partially true because visualization can improve speed, but the best reason is not simply that a visual map is faster than a white paper.
D is correct because stage alignment helps the IR team understand attacker intent and anticipate the next likely action.

NEW QUESTION 220
Which of the following are process improvements that can be realized by implementing a SOAR solution? (Choose two.)

Minimize setup complexity

Define a security strategy

Minimize security attacks

Generate reports and metrics

NEW QUESTION 221
A systems administrator is reviewing the output of a vulnerability scan.
INSTRUCTIONS
Review the information in each tab.
Based on the organization’s environment architecture and remediation standards, select the server to be patched within 14 days and select the appropriate technique and mitigation.

NEW QUESTION 222
A security administrator has found indications of dictionary attacks against the company’s external-facing portal. Which of the following should be implemented to best mitigate the password attacks?

Multifactor authentication

Password complexity

Web application firewall

Lockout policy

Dictionary attacks involve an attacker attempting to guess passwords by using a list of common passwords.
Implementing a lockout policy is effective because it limits the number of login attempts, thereby hindering the attacker’s ability to repeatedly attempt different passwords. Lockout policies are standard in cybersecurity practices to prevent brute-force and dictionary attacks by temporarily disabling an account after a certain number of failed login attempts. According to CompTIA Security+ standards, password complexity (option B) and multifactor authentication (option A) are helpful but are not as immediately effective in directly preventing repeated attempts as a lockout policy.

NEW QUESTION 223
The vulnerability analyst reviews threat intelligence regarding emerging vulnerabilities affecting workstations that are used within the company:

Which of the following vulnerabilities should the analyst be most concerned about, knowing that end users frequently click on malicious links sent via email?

Vulnerability A

Vulnerability B

Vulnerability C

Vulnerability D

To determine the correct vulnerability, you must map the specific threat intelligence (users clicking email links) to the CVSS Base Metrics provided in the table.
1. Analyze the Scenario:
* Threat Vector: ” End users frequently click on malicious links sent via email. “
* Attack Vector implication: The attack is coming from outside the organization (remote), meaning the Attack Vector must be Network.
* Interaction implication: The success of the attack relies on the user performing an action (clicking), meaning User Interaction must be Yes (Required).
2. Evaluate the Table:
Vulnerability
Attack Vector
Attack Complexity
Auth Required
User Interaction
Analysis
A
Network
Low
No
Yes
Perfect Match. This represents a remote exploit (e.g., a browser drive-by download or malicious site) that triggers when a user clicks a link. It requires no authentication and is easy to execute.
B
Local
Low
Yes
Yes
Incorrect. ” Local ” usually implies the attacker already has physical access or a foothold. ” Auth Required ” makes it harder to exploit than A.
C
Network
High
Yes
Yes
Incorrect. ” High ” complexity and ” Auth Required ” make this significantly less likely/severe than A for a mass phishing campaign.
D
Local
Low
No
No
Incorrect. ” Local ” vector and ” User Interaction: No ” do not align with the specific threat of users clicking links.
3. Conclusion:
Vulnerability A is the highest risk because it is Remotely Exploitable (Network), easy to perform (Complexity: Low), requires No Authentication (anyone who clicks is vulnerable), and directly targets the behavior identified in the threat intelligence (User Interaction: Yes).
* Attack Vector (AV:N): The context of ” email ” typically maps to Network because the payload is delivered over the internet/network stack.
* User Interaction (UI:R): CompTIA defines this metric as required when a user must perform an action (like clicking a link or opening an attachment) for the vulnerability to be successfully exploited.
* Risk Prioritization: Vulnerabilities with Network vectors and Low complexity are generally prioritized over Local/High Complexity ones because they are easier to scale and automate.

NEW QUESTION 224
A security administrator has found indications of dictionary attacks against the company’s external- facing portal. Which of the following should be implemented to best mitigate the password attacks?

Multifactor authentication

Password complexity

Web application firewall

Lockout policy

NEW QUESTION 225
An analyst received an alert regarding an application spawning a suspicious command shell process Upon further investigation, the analyst observes the following registry change occurring immediately after the suspicious event:

Which of the following was the suspicious event able to accomplish?

Impair defenses.

Establish persistence.

Bypass file access controls.

Implement beaconing.

The suspicious event was able to accomplish establishing persistence by creating a registry change that runs a command shell process every time a user logs on. The registry change modifies the Userinit value under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon key, which specifies what programs should run when a user logs on to Windows. By appending “cmd.exe,” to the existing value, the event ensures that a command shell process will be launched every time a user logs on, which can allow the attacker to maintain access to the system or execute malicious commands. The other options are not related to the registry change. Reference: CompTIA Cybersecurity Analyst (CySA+) Certification Exam Objectives (CS0-002), page 10; https://docs.microsoft.com/en-us/windows/win32/sysinfo/userinit-entry

NEW QUESTION 226
A cybersecurity team lead is developing metrics to present in the weekly executive briefs. Executives are interested in knowing how long it takes to stop the spread of malware that enters the network.
Which of the following metrics should the team lead include in the briefs?

Mean time between failures

Mean time to detect

Mean time to remediate

Mean time to contain

Mean time to contain is the metric that the cybersecurity team lead should include in the weekly executive briefs, as it measures how long it takes to stop the spread of malware that enters the network. Mean time to contain is the average time it takes to isolate and neutralize an incident or a threat, such as malware, from the time it is detected. Mean time to contain is an important metric for evaluating the effectiveness and efficiency of the incident response process, as well as the potential impact and damage of the incident or threat. A lower mean time to contain indicates a faster and more successful response, which can reduce the risk and cost of the incident or threat. Mean time to contain can also be compared with other metrics, such as mean time to detect or mean time to remediate, to identify gaps or areas for improvement in the incident response process.

NEW QUESTION 227
During an incident, analysts need to rapidly investigate by the investigation and leadership teams. Which of the following best describes how PII should be safeguarded during an incident?

Implement data encryption and close the data so only the company has access.

Ensure permissions are limited in the investigation team and encrypt the data.

Implement data encryption and create a standardized procedure for deleting data that is no longer needed.

Ensure that permissions are open only to the company.

The best option to safeguard PII during an incident is to ensure permissions are limited in the investigation team and encrypt the data. This is because limiting permissions reduces the risk of unauthorized access or leakage of sensitive data, and encryption protects the data from being read or modified by anyone who does not have the decryption key. Option A is not correct because closing the data may hinder the investigation process and prevent collaboration with other parties who may need access to the data. Option C is not correct because deleting data that is no longer needed may violate legal or regulatory requirements for data retention, and may also destroy potential evidence for the incident. Option D is not correct because opening permissions to the company may expose the data to more people than necessary, increasing the risk of compromise or misuse.

NEW QUESTION 228
Using open-source intelligence gathered from technical forums, a threat actor compiles and tests a malicious downloader to ensure it will not be detected by the victim organization ‘ s endpoint security protections.
Which of the following stages of the Cyber Kill Chain best aligns with the threat actor ‘ s actions?

Delivery

Reconnaissance

Exploitation

Weaponizatign

Weaponization is the stage of the Cyber Kill Chain where the threat actor creates or modifies a malicious tool to use against a target. In this case, the threat actor compiles and tests a malicious downloader, which is a type of weaponized malware. References: Cybersecurity 101, The Cyber Kill Chain: The Seven Steps of a Cyberattack

NEW QUESTION 229
Which of the following phases of the Cyber Kill Chain involves the adversary attempting to establish communication with a successfully exploited target?

Command and control

Actions on objectives

Exploitation

Delivery

Command and control (C2) is a phase of the Cyber Kill Chain that involves the adversary attempting to establish communication with a successfully exploited target. C2 enables the adversary to remotely control or manipulate the target system or network using various methods, such as malware callbacks, backdoors, botnets, or covert channels. C2 allows the adversary to maintain persistence, exfiltrate data, execute commands, deliver payloads, or spread to other systems or networks.

NEW QUESTION 230
A security analyst found the following vulnerability on the company’s website:
<INPUT TYPE=”IMAGE” SRC=”javascript:alert(‘test’);”>
Which of the following should be implemented to prevent this type of attack in the future?

Input sanitization

Output encoding

Code obfuscation

Prepared statements

This is a type of web application vulnerability called cross-site scripting (XSS), which allows an attacker to inject malicious code into a web page that is viewed by other users. XSS can be used to steal cookies, session tokens, credentials, or other sensitive information, or to perform actions on behalf of the victim.
Input sanitization is a technique that prevents XSS attacks by checking and filtering the user input before processing it. Input sanitization can remove or encode any characters or strings that may be interpreted as code by the browser, such as <, >, “, ‘, or javascript:. Input sanitization can also validate the input against a predefined format or range of values, and reject any input that does not match.
Output encoding is a technique that prevents XSS attacks by encoding the output before sending it to the browser. Output encoding can convert any characters or strings that may be interpreted as code by the browser into harmless entities, such as <, >, “, ‘, or javascript:. Output encoding can also escape any special characters that may have a different meaning in different contexts, such as , /, or ;.
Code obfuscation is a technique that makes the source code of a web application more difficult to read and understand by humans. Code obfuscation can use techniques such as renaming variables and functions, removing comments and whitespace, replacing literals with expressions, or adding dummy code. Code obfuscation can help protect the intellectual property and trade secrets of a web application, but it does not prevent XSS attacks.
