質問 # 40
A technician is analyzing output from a popular network mapping tool for a PCI audit:
Which of the following best describes the output?
- A. The Secure Shell port on this host is closed
- B. The host is running excessive cipher suites.
- C. The host is allowing insecure cipher suites.
- D. The host is not up or responding.
正解：C
解説：
Explanation
The output shows the result of running the ssl-enum-ciphers script with Nmap, which is a tool that can scan web servers for supported SSL/TLS cipher suites. Cipher suites are combinations of cryptographic algorithms that are used to establish secure communication between a client and a server. The output shows the cipher suites that are supported by the server, along with a letter grade (A through F) indicating the strength of the connection. The output also shows the least strength, which is the strength of the weakest cipher offered by the server. In this case, the least strength is F, which means that the server is allowing insecure cipher suites that are vulnerable to attacks or have been deprecated. For example, the output shows that the server supports SSLv3, which is an outdated and insecure protocol that is susceptible to the POODLE attack. The output also shows that the server supports RC4, which is a weak and broken stream cipher that should not be used.
Therefore, the best description of the output is that the host is allowing insecure cipher suites. The other descriptions are not accurate, as they do not reflect what the output shows. The host is not up or responding is incorrect, as the output clearly shows that the host is up and responding to the scan. The host is running excessive cipher suites is incorrect, as the output does not indicate how many cipher suites the host is running, only which ones it supports. The Secure Shell port on this host is closed is incorrect, as the output does not show anything about port 22, which is the default port for Secure Shell (SSH). The output only shows information about port 443, which is the default port for HTTPS.

An organization has experienced a breach of customer transactions. Under the terms of PCI DSS, which of the following groups should the organization report the breach to?
- A. Local law enforcement
- B. PCI Security Standards Council
- C. Federal law enforcement
- D. Card issuer
正解：D
解説：
Under the terms of PCI DSS, an organization that has experienced a breach of customer transactions should report the breach to the card issuer. The card issuer is the financial institution that issues the payment cards to the customers and that is responsible for authorizing and processing the transactions. The card issuer may have specific reporting requirements and procedures for the organization to follow in the event of a breach. The organization should also notify other parties that may be affected by the breach, such as customers, law enforcement, or regulators, depending on the nature and scope of the breach.

質問 # 44
The analyst reviews the following endpoint log entry:
Which of the following has occurred?
- A. New account introduced
- B. Registry change
- C. Privilege escalation
- D. Rename computer
正解：A
解説：
Explanation
The endpoint log entry shows that a new account named "admin" has been created on a Windows system with a local group membership of "Administrators". This indicates that a new account has been introduced on the system with administrative privileges. This could be a sign of malicious activity, such as privilege escalation or backdoor creation, by an attacker who has compromised the system.
質問 # 45
A virtual web server in a server pool was infected with malware after an analyst used the internet to research a system issue. After the server was rebuilt and added back into the server pool, users reported issues with the website, indicating the site could not be trusted. Which of the following is the most likely cause of the server issue?
- A. The digital certificate on the web server was self-signed
- B. The server was supporting weak TLS protocols for client connections.
- C. The malware infected all the web servers in the pool.
- D. The server was configured to use SSI- to securely transmit data
正解：A
解説：
Explanation
A digital certificate is a document that contains the public key and identity information of a web server, and is signed by a trusted third-party authority called a certificate authority (CA). A digital certificate allows the web server to establish a secure connection with the clients using the HTTPS protocol, and also verifies the authenticity of the web server. A self-signed certificate is a digital certificate that is not signed by a CA, but by the web server itself. A self-signed certificate can cause issues with the website, as it may not be trusted by the clients or their browsers. Clients may receive warnings or errors when trying to access the website, indicating that the site could not be trusted or that the connection is not secure. Official References:

質問 # 46
An incident response team found IoCs in a critical server. The team needs to isolate and collect technical evidence for further investigation. Which of the following pieces of data should be collected first in order to preserve sensitive information before isolating the server?
- A. Static IP address
- B. Routing table
- C. Primary boot partition
- D. Hard disk
- E. Malicious tiles
正解：D
解説：
Explanation
The hard disk is the piece of data that should be collected first in order to preserve sensitive information before isolating the server. The hard disk contains all the files and data stored on the server, which may include evidence of malicious activity, such as malware installation, data exfiltration, or configuration changes. The hard disk should be collected using proper forensic techniques, such as creating an image or a copy of the disk and maintaining its integrity using hashing algorithms.
質問 # 47
A security analyst has found the following suspicious DNS traffic while analyzing a packet capture:
* DNS traffic while a tunneling session is active.
* The mean time between queries is less than one second.
* The average query length exceeds 100 characters.
Which of the following attacks most likely occurred?
- A. DNS spoofing
- B. DNS exfiltration
- C. DNS poisoning
- D. DNS zone transfer
正解：B
解説：
Explanation
DNS exfiltration is a technique that uses the DNS protocol to transfer data from a compromised network or device to an attacker-controlled server. DNS exfiltration can bypass firewall rules and security products that do not inspect DNS traffic. The characteristics of the suspicious DNS traffic in the question match the indicators of DNS exfiltration, such as:
DNS traffic while a tunneling session is active: This implies that the DNS protocol is being used to create a covert channel for data transfer.
The mean time between queries is less than one second: This implies that the DNS queries are being sent at a high frequency to maximize the amount of data transferred.
The average query length exceeds 100 characters: This implies that the DNS queries are encoding large amounts of data in the subdomains or other fields of the DNS packets.

質問 # 49
A security analyst receives an alert for suspicious activity on a company laptop An excerpt of the log is shown below:
Which of the following has most likely occurred?
- A. An Office document with a malicious macro was opened.
- B. A web browser vulnerability was exploited.
- C. A credential-stealing website was visited.
- D. A phishing link in an email was clicked
正解：A
解説：
Explanation
An Office document with a malicious macro was opened is the most likely explanation for the suspicious activity on the company laptop, as it reflects the common technique of using macros to execute PowerShell commands that download and run malware. A macro is a piece of code that can automate tasks or perform actions in an Office document, such as a Word file or an Excel spreadsheet. Macros can be useful and legitimate, but they can also be abused by threat actors to deliver malware or perform malicious actions on the system. A malicious macro can be embedded in an Office document that is sent as an attachment in a phishing email or hosted on a compromised website. When the user opens the document, they may be prompted to enable macros or content, which will trigger the execution of the malicious code. The malicious macro can then use PowerShell, which is a scripting language and command-line shell that is built into Windows, to perform various tasks, such as downloading and running malware from a remote URL, bypassing security controls, or establishing persistence on the system. The log excerpt shows that PowerShell was used to download a string from a URL using the WebClient.DownloadString method, which is a common way to fetch and execute malicious code from the internet. The log also shows that PowerShell was used to invoke an expression (iex) that contains obfuscated code, which is another common way to evade detection and analysis.
The other options are not as likely as an Office document with a malicious macro was opened, as they do not match the evidence in the log excerpt. A credential-stealing website was visited is possible, but it does not explain why PowerShell was used to download and execute code from a URL. A phishing link in an email was clicked is also possible, but it does not explain what happened after the link was clicked or how PowerShell was involved. A web browser vulnerability was exploited is unlikely, as it does not explain why PowerShell was used to download and execute code from a URL.
質問 # 50
Which of the following best describes the document that defines the expectation to network customers that patching will only occur between 2:00 a.m. and 4:00 a.m.?
- A. KPI
- B. MOU
- C. LOI
- D. SLA
正解：D
解説：
SLA (Service Level Agreement) is the best term to describe the document that defines the expectation to network customers that patching will only occur between 2:00 a.m. and 4:00 a.m., as it reflects the agreement between a service provider and a customer that specifies the services, quality, availability, and responsibilities that are agreed upon. An SLA is a common type of document that is used in various industries and contexts, such as IT, telecom, cloud computing, or outsourcing. An SLA typically includes metrics and indicators to measure the performance and quality of the service, such as uptime, response time, or resolution time. An SLA also defines the consequences or remedies for any breaches or failures of the service, such as penalties, refunds, or credits. An SLA can help to manage customer expectations, formalize communication, improve productivity, and strengthen relationships. The other terms are not as accurate as SLA, as they describe different types of documents or concepts. LOI (Letter of Intent) is a document that outlines the main terms and conditions of a proposed agreement between two or more parties, before a formal contract is signed. An LOI is usually non-binding and expresses the intention or interest of the parties to enter into a future agreement. An LOI can help to clarify the key points of a deal, facilitate negotiations, or demonstrate commitment. MOU (Memorandum of Understanding) is a document that describes a mutual agreement or cooperation between two or more parties, without creating any legal obligations or commitments. An MOU is usually more formal than an LOI, but less formal than a contract. An MOU can help to establish a common ground, define roles and responsibilities, or outline expectations and goals. KPI (Key Performance Indicator) is a concept that refers to a measurable value that demonstrates how effectively an organization or individual is achieving its key objectives or goals. A KPI is usually quantifiable and specific, such as revenue growth, customer satisfaction, or employee retention. A KPI can help to track progress, evaluate performance, or identify areas for improvement.
質問 # 51
A company that has a geographically diverse workforce and dynamic IPs wants to implement a vulnerability scanning method with reduced network traffic. Which of the following would best meet this requirement?
- A. Credentialed
- B. Agent-based
- C. External
- D. Non-credentialed
正解：B
解説：
Agent-based vulnerability scanning is a method that involves installing software agents on the target systems or networks that can perform local scans and report the results to a central server or console. Agent-based vulnerability scanning can reduce network traffic, as the scans are performed locally and only the results are transmitted over the network. Agent-based vulnerability scanning can also provide more accurate and up-to-date results, as the agents can scan continuously or on-demand, regardless of the system or network status or location.
質問 # 52
Which of the following is the best reason why organizations need operational security controls?
- A. To supplement areas that other controls cannot address
- B. To prevent disclosure by potential insider threats
- C. To limit physical access to areas that contain sensitive data
- D. To assess compliance automatically against a secure baseline
正解：A
解説：
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.

質問 # 53
A security analyst who works in the SOC receives a new requirement to monitor for indicators of compromise. Which of the following is the first action the analyst should take in this situation?
- A. Develop a new signature to block the indicators of compromise.
- B. Develop a query to search for the indicators of compromise.
- C. Develop a new signature to alert on the indicators of compromise.
- D. Develop a dashboard to track the indicators of compromise.
正解：B
解説：
Developing a query to search for the indicators of compromise is the first action the analyst should take in this situation. Indicators of compromise (IOCs) are pieces of information that suggest a system or network has been compromised by an attacker. IOCs can include IP addresses, domain names, file hashes, URLs, or other artifacts that are associated with malicious activity. Developing a query to search for IOCs can help to identify any potential incidents or threats in the environment and initiate further investigation or response .
質問 # 54
A security analyst is performing vulnerability scans on the network. The analyst installs a scanner appliance, configures the subnets to scan, and begins the scan of the network. Which of the following would be missing from a scan performed with this configuration?
- A. IP address
- B. Open ports
- C. Registry key values
- D. Operating system version
正解：C
解説：
Explanation
Registry key values would be missing from a scan performed with this configuration, as the scanner appliance would not have access to the Windows Registry of the scanned systems. The Windows Registry is a database that stores configuration settings and options for the operating system and installed applications. To scan the Registry, the scanner would need to have credentials to log in to the systems and run a local agent or script.
The other items would not be missing from the scan, as they can be detected by the scanner appliance without credentials. Operating system version can be identified by analyzing service banners or fingerprinting techniques. Open ports can be discovered by performing a port scan or sending probes to common ports. IP address can be obtained by resolving the hostname or using network discovery tools.

質問 # 55
Which of the following lines from this output most likely indicates that attackers could quickly use brute force and determine the negotiated secret session key?
- A. TLS_DHE_RSA_WITH_AES_128_CBC_SHA 128 DH (1024 bits)
- B. TLS_DHE_RSA_WITH_AES_256_GCM_SHA256 DH (2048 bits)
- C. TLS_RSA_WITH_AES_256_CBC_SHA 256
- D. TLS_RSA_WITH_DES_CBC_SHA 56
正解：A
解説：
The line from this output that most likely indicates that attackers could quickly use brute force and determine the negotiated secret session key is TLS_DHE_RSA_WITH_AES_128_CBC_SHA 128 DH (1024 bits). This line indicates that the cipher suite uses Diffie-Hellman ephemeral (DHE) key exchange with RSA authentication, AES 128-bit encryption with cipher block chaining (CBC) mode, and SHA-1 hashing. The DHE key exchange uses a 1024-bit Diffie-Hellman group, which is considered too weak for modern security standards and can be broken by attackers using sufficient computing power. The other lines indicate stronger cipher suites that use longer key lengths or more secure algorithms.

A new prototype for a company's flagship product was leaked on the internet As a result, the management team has locked out all USB drives Optical drive writers are not present on company computers The sales team has been granted an exception to share sales presentation files with third parties Which of the following would allow the IT team to determine which devices are USB enabled?
- A. Device encryption
- B. SIEMIogs
- C. Data loss prevention
- D. Asset tagging
正解：B
解説：
A security information and event management (SIEM) system is a tool that collects and analyzes log data from various sources and provides alerts and reports on security incidents and events. A SIEM system can help the IT team to determine which devices are USB enabled by querying the log data for events related to USB device insertion, removal, or usage. The other options are not relevant or effective for this purpose.

While reviewing web server logs, a security analyst found the following line:<IMG SRC='vbscript:msgbox("test")'> Which of the following malicious activities was attempted?
- A. Server-side request forgery
- B. XML injection
- C. Cross-site scripting
- D. Command injection
正解：C
解説：
XSS is a type of web application attack that exploits the vulnerability of a web server or browser to execute malicious scripts or commands on the client-side. XSS attackers inject malicious code, such as JavaScript, VBScript, HTML, or CSS, into a web page or application that is viewed by other users. The malicious code can then access or manipulate the user's session, cookies, browser history, or personal information, or perform actions on behalf of the user, such as stealing credentials, redirecting to phishing sites, or installing malware12 The line in the web server log shows an example of an XSS attack using VBScript. The attacker tried to insert an <IMG> tag with a malicious SRC attribute that contains a VBScript code. The VBScript code is intended to display a message box with the text "test" when the user views the web page or application. This is a simple and harmless example of XSS, but it could be used to test the vulnerability of the web server or browser, or to launch more sophisticated and harmful attacks3

Joe, a leading sales person at an organization, has announced on social media that he is leaving his current role to start a new company that will compete with his current employer. Joe is soliciting his current employer's customers. However, Joe has not resigned or discussed this with his current supervisor yet. Which of the following would be the best action for the incident response team to recommend?
- A. Reimage the PC based on standard operating procedures
- B. Initiate a remote wipe of Joe's PC using mobile device management
- C. Perform no action until HR or legal counsel advises on next steps
- D. Isolate Joe's PC from the network
正解：C
解説：
The best action for the incident response team to recommend in this scenario is to perform no action until HR or legal counsel advises on next steps. This action can help avoid any potential legal or ethical issues, such as violating employee privacy rights, contractual obligations, or organizational policies. This action can also help ensure that any evidence or information collected from the employee's system or network is admissible and valid in case of any legal action or dispute. The incident response team should consult with HR or legal counsel before taking any action that may affect the employee's system or network.
質問 # 59
A cybersecurity analyst is concerned about attacks that use advanced evasion techniques. Which of the following would best mitigate such attacks?
- A. Updating the antivirus software
- B. Installing a proxy server
- C. Applying network segmentation
- D. Keeping IPS rules up to date
正解：D
解説：
Keeping IPS rules up to date is the best way to mitigate attacks that use advanced evasion techniques. An IPS (intrusion prevention system) is a security device that monitors network traffic and blocks or prevents malicious activity based on predefined rules or signatures. Advanced evasion techniques are cyberattacks that combine various evasion methods to bypass security detection and protection tools, such as IPS. Keeping IPS rules up to date can help to ensure that the IPS can recognize and block the latest advanced evasion techniques and prevent them from compromising the network .
質問 # 60
A company's user accounts have been compromised. Users are also reporting that the company's internal portal is sometimes only accessible through HTTP, other times; it is accessible through HTTPS. Which of the following most likely describes the observed activity?
- A. An error was caused by BGP due to new rules applied over the company's internal routers
- B. The web server cannot handle an increasing amount of HTTPS requests so it forwards users to port 80
- C. An on-path attack is being performed by someone with internal access that forces users into port 80
- D. There is an issue with the SSL certificate causinq port 443 to become unavailable for HTTPS access
正解：C
解説：
Explanation
An on-path attack is a type of man-in-the-middle attack where an attacker intercepts and modifies network traffic between two parties. In this case, someone with internal access may be performing an on-path attack by forcing users into port 80, which is used for HTTP communication, instead of port 443, which is used for HTTPS communication. This would allow the attacker to compromise the user accounts and access the company's internal portal.
質問 # 61
A managed security service provider is having difficulty retaining talent due to an increasing workload caused by a client doubling the number of devices connected to the network. Which of the following would best aid in decreasing the workload without increasing staff?
- A. SIEM
- B. SOAR
- C. EDR
- D. XDR
正解：B
解説：
SOAR stands for Security Orchestration, Automation and Response, which is a set of features that can help security teams manage, prioritize and respond to security incidents more efficiently and effectively. SOAR can help decrease the workload without increasing staff by automating repetitive tasks, streamlining workflows, integrating different tools and platforms, and providing actionable insights and recommendations. SOAR is also one of the current trends that CompTIA CySA+ covers in its exam objectives. Official Reference:

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?
- A. Mean time between failures
- B. Mean time to remediate
- C. Mean time to detect
- D. Mean time to contain
正解：D
解説：
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.
質問 # 64
Which of the following best describes the process of requiring remediation of a known threat within a given time frame?
- A. MOU
- B. Organizational governance
- C. Best-effort patching
- D. SLA
正解：D
解説：
Explanation
An SLA (Service Level Agreement) is a contract or agreement between a service provider and a customer that defines the expected level of service, performance, quality, and availability of the service. An SLA also specifies the responsibilities, obligations, and penalties for both parties in case of non-compliance or breach of the agreement. An SLA can help organizations to ensure that their security services are delivered in a timely and effective manner, and that any security incidents or vulnerabilities are addressed and resolved within a specified time frame. An SLA can also help to establish clear communication, expectations, and accountability between the service provider and the customer12 An MOU (Memorandum of Understanding) is a document that expresses a mutual agreement or understanding between two or more parties on a common goal or objective. An MOU is not legally binding, but it can serve as a basis for future cooperation or collaboration. An MOU may not be suitable for requiring remediation of a known threat within a given time frame, as it does not have the same level of enforceability, specificity, or measurability as an SLA.
Best-effort patching is an informal and ad hoc approach to applying security patches or updates to systems or software. Best-effort patching does not follow any defined process, policy, or schedule, and relies on the availability and discretion of the system administrators or users. Best-effort patching may not be effective or efficient for requiring remediation of a known threat within a given time frame, as it does not guarantee that the patches are applied correctly, consistently, or promptly. Best-effort patching may also introduce new risks or vulnerabilities due to human error, compatibility issues, or lack of testing.
Organizational governance is the framework of rules, policies, procedures, and processes that guide and direct the activities and decisions of an organization. Organizational governance can help to establish the roles, responsibilities, and accountabilities of different stakeholders within the organization, as well as the goals, values, and principles that shape the organizational culture and behavior. Organizational governance can also help to ensure compliance with internal and external standards, regulations, and laws. Organizational governance may not be sufficient for requiring remediation of a known threat within a given time frame, as it does not specify the details or metrics of the service delivery or performance. Organizational governance may also vary depending on the size, structure, and nature of the organization.
