Which of the following most accurately describes the result of the scan?
- A. An output of characters > and " as the parameters used m the attempt
- B. The vulnerable parameter ID hccp://l72.31.15.2/1.php?id-2 and unfiltered characters returned
- C. The vulnerable parameter and characters > and " with a reflected XSS attempt
- D. The vulnerable parameter and unfiltered or encoded characters passed > and " as unsafe
Answer: C
Explanation:
Explanation
A cross-site scripting (XSS) attack is a type of web application attack that injects malicious code into a web page that is then executed by the browser of a victim user. A reflected XSS attack is a type of XSS attack where the malicious code is embedded in a URL or a form parameter that is sent to the web server and then reflected back to the user's browser. In this case, the Nmap scan shows that the web server is vulnerable to a reflected XSS attack, as it returns the characters > and " without any filtering or encoding. The vulnerable parameter is id in the URL http://172.31.15.2/1.php?id=2.
NEW QUESTION # 62
An organization implemented an extensive firewall access-control blocklist to prevent internal network ranges from communicating with a list of IP addresses of known command-and-control domains A security analyst wants to reduce the load on the firewall. Which of the following can the analyst implement to achieve similar protection and reduce the load on the firewall?
- A. DNS sinkholing
- B. A DLP system
- C. An inline IDS
- D. IP address allow list
Answer: A
Explanation:
DNS sinkholing is a mechanism that can prevent internal network ranges from communicating with a list of IP addresses of known command-and-control domains by returning a false or controlled IP address for those domains. This can reduce the load on the firewall by intercepting the DNS requests before they reach the firewall and diverting them to a sinkhole server. The other options are not relevant or effective for this purpose. Reference: CompTIA Cybersecurity Analyst (CySA+) Certification Exam Objectives (CS0-002), page 9; https://www.enisa.europa.eu/topics/incident-response/glossary/dns-sinkhole
NEW QUESTION # 63
A security analyst discovers an LFI vulnerability that can be exploited to extract credentials from the underlying host. Which of the following patterns can the security analyst use to search the web server logs for evidence of exploitation of that particular vulnerability?
- A. cat /proc/self/
- B. curl localhost
- C. /etc/ shadow
- D. ; printenv
Answer: C
Explanation:
Explanation
/etc/shadow is the pattern that the security analyst can use to search the web server logs for evidence of exploitation of the LFI vulnerability that can be exploited to extract credentials from the underlying host. LFI stands for Local File Inclusion, which is a vulnerability that allows an attacker to include local files on the web server into the output of a web application. LFI can be exploited to extract sensitive information from the web server, such as configuration files, passwords, or source code. The /etc/shadow file is a file that stores the encrypted passwords of all users on a Linux system. If an attacker can exploit the LFI vulnerability to include this file into the web application output, they can obtain the credentials of the users on the web server.
Therefore, the security analyst can look for /etc/shadow in the request line of the web server logs to see if any attacker has attempted or succeeded in exploiting the LFI vulnerability. Official References:

A security analyst is monitoring a company's network traffic and finds ping requests going to accounting and human resources servers from a SQL server. Upon investigation, the analyst discovers a technician responded to potential network connectivity issues. Which of the following is the best way for the security analyst to respond?
- A. Report this activity as a false positive, as the activity is legitimate.
- B. Recommend network segmentation to the management team as a way to secure the various environments.
- C. Isolate the system and begin a forensic investigation to determine what was compromised.
- D. Implement host-based firewalls on all systems to prevent ping sweeps in the future.
Answer: A
Explanation:
Reporting this activity as a false positive, as the activity is legitimate, is the best way for the security analyst to respond. A false positive is a condition in which harmless traffic is classified as a potential network attack by a security monitoring tool. Ping requests are a common network diagnostic tool that can be used to test network connectivity issues. The technician who responded to potential network connectivity issues was performing a legitimate task and did not pose any threat to the accounting and human resources servers .

EDR can help to ensure that all devices are patched and running some sort of protection against malicious software by providing continuous visibility, threat detection, incident response, and remediation capabilities. EDR can also help to enforce security policies and compliance requirements across all devices .
NEW QUESTION # 69
An incident response team is working with law enforcement to investigate an active web server compromise.
The decision has been made to keep the server running and to implement compensating controls for a period of time. The web service must be accessible from the internet via the reverse proxy and must connect to a database server. Which of the following compensating controls will help contain the adversary while meeting the other requirements? (Select two).
- A. Comment out the HTTP account in the / etc/passwd file of the web server
- B. Move the database from the database server to the web server.
- C. Deploy EDR on the web server and the database server to reduce the adversaries capabilities.
- D. Drop the tables on the database server to prevent data exfiltration.
- E. Stop the httpd service on the web server so that the adversary can not use web exploits
- F. use micro segmentation to restrict connectivity to/from the web and database servers.
Answer: C,F
Explanation:
Explanation
Deploying EDR on the web server and the database server to reduce the adversaries capabilities and using micro segmentation to restrict connectivity to/from the web and database servers are two compensating controls that will help contain the adversary while meeting the other requirements. A compensating control is a security measure that is implemented to mitigate the risk of a vulnerability or an attack when the primary control is not feasible or effective. EDR stands for Endpoint Detection and Response, which is a tool that monitors endpoints for malicious activity and provides automated or manual response capabilities. EDR can help contain the adversary by detecting and blocking their actions, such as data exfiltration, lateral movement, privilege escalation, or command execution. Micro segmentation is a technique that divides a network into smaller segments based on policies and rules, and applies granular access controls to each segment. Micro segmentation can help contain the adversary by isolating the web and database servers from other parts of the network, and limiting the traffic that can flow between them. Official References:

NEW QUESTION # 70
Which of the following phases of the Cyber Kill Chain involves the adversary attempting to establish communication with a successfully exploited target?
- A. Delivery
- B. Actions on objectives
- C. Command and control
- D. Exploitation
Answer: C
Explanation:
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 # 71
A company is in the process of implementing a vulnerability management program. no-lich of the following scanning methods should be implemented to minimize the risk of OT/ICS devices malfunctioning due to the vulnerability identification process?
- A. Non-credentialed scanning
- B. Passive scanning
- C. Agent-based scanning
- D. Credentialed scanning
Answer: B
Explanation:
Explanation
Passive scanning is a method of vulnerability identification that does not send any packets or probes to the target devices, but rather observes and analyzes the network traffic passively. Passive scanning can minimize the risk of OT/ICS devices malfunctioning due to the vulnerability identification process, as it does not interfere with the normal operation of the devices or cause any network disruption. Passive scanning can also detect vulnerabilities that active scanning may miss, such as misconfigured devices, rogue devices or unauthorized traffic. Official References:

NEW QUESTION # 72
After identifying a threat, a company has decided to implement a patch management program to remediate vulnerabilities. Which of the following risk management principles is the company exercising?
- A. Accept
- B. Transfer
- C. Mitigate
- D. Avoid
Answer: C
Explanation:
Explanation
Mitigate is the best term to describe the risk management principle that the company is exercising, as it means to reduce the likelihood or impact of a risk. By implementing a patch management program to remediate vulnerabilities, the company is mitigating the threat of cyberattacks that could exploit those vulnerabilities and compromise the security or functionality of the systems. The other terms are not as accurate as mitigate, as they describe different risk management principles. Transfer means to shift the responsibility or burden of a risk to another party, such as an insurer or a contractor. Accept means to acknowledge the existence of a risk and decide not to take any action to reduce it, usually because the risk is low or the cost of mitigation is too high. Avoid means to eliminate the possibility of a risk by changing the plans or activities that could cause it, such as cancelling a project or discontinuing a service.
NEW QUESTION # 73
The Chief Executive Officer of an organization recently heard that exploitation of new attacks in the industry was happening approximately 45 days after a patch was released. Which of the following would best protect this organization?
- A. Third-party application testing
- B. A mean time to detect of 45 days
- C. A mean time to respond of 15 days
- D. A mean time to remediate of 30 days
Answer: D
Explanation:
Explanation
A mean time to remediate (MTTR) is a metric that measures how long it takes to fix a vulnerability after it is discovered. A MTTR of 30 days would best protect the organization from the new attacks that are exploited 45 days after a patch is released, as it would ensure that the vulnerabilities are fixed before they are exploited
NEW QUESTION # 74
Given the Nmap request below:
Which of the following actions will an attacker be able to initiate directly against this host?
- A. A brute-force attack
- B. Password sniffing
- C. An SQL injection
- D. ARP spoofing
Answer: A
Explanation:
The Nmap command given in the question performs a TCP SYN scan (-sS), a service version detection scan (-sV), an OS detection scan (-O), and a port scan for ports 1-1024 (-p 1-1024) on the host 192.168.1.1. This command will reveal information about the host's operating system, open ports, and running services, which can be used by an attacker to launch a brute-force attack against the host. A brute-force attack is a method of guessing passwords or encryption keys by trying many possible combinations until finding the correct one. An attacker can use the information from the Nmap scan to target specific services or protocols that may have weak or default credentials, such as FTP, SSH, Telnet, or HTTP.

- A. Focus on common attack vectors first.
- B. Focus on incidents that have a high chance of reputation harm.
- C. Focus on incidents that may require law enforcement support.
- D. Focus on incidents that affect critical systems.
Answer: D
Explanation:
An incident response plan should cover the most important and likely scenarios that could compromise the security and operations of an organization. According to various sources of best practices123, an incident response plan should start by conducting a risk assessment to identify potential threats and vulnerabilities, and prioritize the critical systems that need to be protected and restored in case of an incident. Focusing on incidents that affect critical systems ensures that the incident response plan covers the most severe and impactful situations that could harm the organization's mission, reputation, or legal obligations.
