NEW QUESTION 3
A company recently implemented a patch management policy; however, vulnerability scanners have still been flagging several hosts, even after the completion of the patch process. Which of the following is the most likely cause of the issue?
- A. The vendor firmware lacks support.
- B. Zero-day vulnerabilities are being discovered.
- C. Third-party applications are not being patched.
- D. Code development is being outsourced.
Third-party applications are applications that are developed and provided by external vendors or sources, rather than by the organization itself. Third-party applications may introduce security risks if they are not properly vetted, configured, or updated. One of the most likely causes of vulnerability scanners flagging several hosts after the completion of the patch process is that third-party applications are not being patched. Patching is the process of applying updates or fixes to software to address bugs, vulnerabilities, or performance issues. Patching third-party applications is essential for maintaining their security and functionality, as well as preventing attackers from exploiting known flaws.

NEW QUESTION 4
A company wants to modify its current backup strategy to modify its current backup strategy to minimize the number of backups that would need to be restored in case of data loss. Which of the following would be the BEST backup strategy
- A. Incremental backups followed by differential backups
- B. Full backups followed by incremental backups
- C. Delta backups followed by differential backups
- D. Incremental backups followed by delta backups
- E. Full backup followed by different backups
The best backup strategy for minimizing the number of backups that need to be restored in case of data loss is full backups followed by incremental backups. This strategy allows for a complete restoration of data by restoring the most recent full backup followed by the most recent incremental backup.

NEW QUESTION 5
An engineer recently deployed a group of 100 web servers in a cloud environment. Per the security policy, all web-server ports except 443 should be disabled. Which of the following can be
used to accomplish this task?
- A. Application allow list
- B. Load balancer
- C. Host-based firewall
- D. VPN
A host-based firewall is a software application that runs on each individual host and controls the incoming and outgoing network traffic based on a set of rules. A host-based firewall can be used to block or allow specific ports, protocols, IP addresses, or applications.
An engineer can use a host-based firewall to accomplish the task of disabling all web-server ports except 443 on a group of 100 web servers in a cloud environment. The engineer can configure the firewall rules on each web server to allow only HTTPS traffic on port 443 and deny any other traffic. Alternatively, the engineer can use a centralized management tool to deploy and enforce the firewall rules across all web servers.
NEW QUESTION 6
A security team suspects that the cause of recent power consumption overloads is the unauthorized use of empty power outlets in the network rack Which of the following options will mitigate this issue without compromising the number of outlets available?
- A. Adding a new UPS dedicated to the rack
- B. Installing a managed PDU
- C. Using only a dual power supplies unit
- D. Increasing power generator capacity
A managed Power Distribution Unit (PDU) allows you to monitor and control power outlets on the rack. This will allow the security team to identify which devices are drawing power and from which outlets, which can help to identify any unauthorized devices. Moreover, with a managed PDU, you can also control the power to outlets, turn off outlets that are not in use, and set up alerts if an outlet is overloaded. This will help to mitigate the issue of power consumption overloads without compromising the number of outlets available.

NEW QUESTION 7
A Security engineer needs to implement an MDM solution that complies with the corporate mobile device policy. The policy states that in order for mobile users to access corporate resources on their devices, the following requirements must be met:
Mobile device OSs must be patched up to the latest release.
A screen lock must be enabled (passcode or biometric).
Corporate data must be removed if the device is reported lost or stolen.
Which of the following controls should the security engineer configure? (Select two).
- A. Disable firmware over-the-air
- B. Storage segmentation
- C. Posture checking
- D. Remote wipe
- E. Full device encryption
- F. Geofencing
Posture checking and remote wipe are two controls that the security engineer should configure to comply with the corporate mobile device policy. Posture checking is a process that verifies if a mobile device meets certain security requirements before allowing it to access corporate resources. For example, posture checking can check if the device OS is patched up to the latest release and if a screen lock is enabled. Remote wipe is a feature that allows the administrator to erase all data from a mobile device remotely, in case it is lost or stolen. This can prevent unauthorized access to corporate data on the device.
NEW QUESTION 8
A web server log contains two million lines. A security analyst wants to obtain the next 500 lines starting from line 4,600. Which of the following commands will help the security analyst to achieve this objective?
- A. cat webserver.log | head -4600 | tail +500 |
- B. cat webserver.log | tail -1995400 | tail -500 |
- C. cat webserver.log | tail -4600 | head -500 |
- D. cat webserver.log | head -5100 | tail -500 |
the cat command displays the contents of a file, the head command displays the first lines of a file, and the
tail command displays the last lines of a file. To display a specific number of lines from a file, you can use a
minus sign followed by a number as an option for head or tail. For example, head -10 will display the first 10 lines of a file.
To obtain the next 500 lines starting from line 4,600, you need to use both head and tail commands. https://www.professormesser.com/security-plus/sy0-601/sy0-601-video/file-manipulation-tools/
NEW QUESTION 9
Which of the following would help ensure a security analyst is able to accurately measure the overall risk to an organization when a new vulnerability is disclosed?
- A. A full inventory of all hardware and software
- B. Documentation of system classifications
- C. A list of system owners and their departments
- D. Third-party risk assessment documentation
A full inventory of all hardware and software would help ensure a security analyst is able to accurately measure the overall risk to an organization when a new vulnerability is disclosed, as it would allow the analyst to identify which systems and applications are affected by the vulnerability and prioritize the remediation efforts accordingly. A full inventory would also help the analyst to determine the impact and likelihood of a successful exploit, as well as the potential loss of confidentiality, integrity and availability of the data and services.

NEW QUESTION 10
The Chief Executive Officer (CEO) of an organization would like staff members to have the flexibility to work from home anytime during business hours, including during a pandemic or crisis. However, the CEO is concerned that some staff members may take advantage of the flexibility and work from high-risk countries while on holiday or outsource work to a third-party organization in another country. The Chief Information Officer believes the company can implement some basic controls to mitigate the majority of the risk. Which of the following would be best to mitigate the CEO's concerns? (Select two).
- A. Geolocation
- B. Time-of-day restrictions
- C. Certificates
- D. Tokens
- E. Geotagging
- F. Role-based access controls
Geolocation and time-of-day restrictions would be best to mitigate the CEO’s concerns about staff members working from high-risk countries while on holiday or outsourcing work to a third-party organization in another country. Geolocation is a technique that involves determining the physical location of a device or user based on its IP address, GPS coordinates, Wi-Fi signals, or other indicators. Time-of-day restrictions are policies that limit the access or usage of resources based on the time of day or week. Geolocation and time-of-day restrictions can help to enforce access control rules, prevent unauthorized access, detect anomalous behavior, and comply with regulations.

A company is developing a new initiative to reduce insider threats. Which of the following should the company focus on to make the greatest impact?
- A. Social media analysis
- B. Least privilege
- C. Nondisclosure agreements
- D. Mandatory vacation
Least privilege is a security principle that states that users and processes should only have the minimum level of access and permissions required to perform their tasks. This reduces the risk of insider threats by limiting the potential damage that a malicious or compromised user or process can cause to the system or data.

NEW QUESTION 14
A user reports constant lag and performance issues with the wireless network when working at a local coffee shop A security analyst walks the user through an installation of Wireshark and gets a five-minute pcap to analyze. The analyst observes the following output:
Which of the following attacks does the analyst most likely see in this packet capture?
- A. Session replay
- B. Evil twin
- C. Bluejacking
- D. ARP poisoning
An evil twin is a type of wireless network attack that involves setting up a rogue access point that mimics a legitimate one. It can trick users into connecting to the rogue access point instead of the real one, and then intercept or modify their traffic, steal their credentials, launch phishing pages, etc. In this packet capture, the analyst can see that there are two access points with the same SSID (CoffeeShop) but different MAC addresses (00:0c:41:82:9c:4f and 00:0c:41:82:9c:4e). This indicates that one of them is an evil twin that is trying to impersonate the other one.
NEW QUESTION 15
Which of the following must be in place before implementing a BCP?
- A. SLA
- B. AUP
- C. NDA
- D. BIA
A Business Impact Analysis (BIA) is a critical component of a Business Continuity Plan (BCP). It identifies and prioritizes critical business functions and determines the impact of their disruption. References: CompTIA Security+ Study Guide 601, Chapter 10
NEW QUESTION 16
A security analyst is reviewing SIEM logs during an ongoing attack and notices the following:
.42 F..42F.. $2Fetct2Fshadow
http: //company.com/../../../ ../etc/passwd
Which of the following best describes the type of attack?
- A. SQLi
- B. CSRF
- C. API attacks
- D. Directory traversal
Directory traversal (also known as file path traversal) is a web security vulnerability that allows an attacker to read arbitrary files on the server that is running an application. This might include application code and data, credentials for back-end systems, and sensitive operating system files1. In some cases, an attacker might be able to write to arbitrary files on the server, allowing them to modify application data or behavior, and ultimately take full control of the server1.
Directory traversal in its simplest form uses the …/ pattern, which means to step up one level in the directory structure. By repeating this pattern, an attacker can traverse to the root directory and then access any file or folder on the server. For example, the following request attempts to read the Unix password file /etc/passwd from the server:
Some web applications may implement some defenses against directory traversal attacks, such as filtering out
…/ patterns or percent-decoding the user input before validating it. However, these defenses can often be bypassed by using variations or encoding techniques. For example, the following requests use different ways to represent …/ or / characters:
These requests may still result in directory traversal attacks if the web application does not properly handle them12.
* A. SQLi. This is not the correct answer, because SQLi stands for SQL Injection, which is an attack that exploits a vulnerability in a web application’s database layer, where malicious SQL statements are inserted into an entry field for execution3. The requests in the question do not contain any SQL statements or commands.
* B. CSRF. This is not the correct answer, because CSRF stands for Cross-Site Request Forgery, which is an attack that exploits the trust a web server has in a user’s browser, where malicious requests are sent to the web server using the user’s credentials4. The requests in the question do not indicate that they are forged or sent by another website.
* C. API attacks. This is not the correct answer, because API stands for Application Programming Interface, which is a set of rules and specifications that allow software components to communicate and exchange data. API attacks are attacks that target the vulnerabilities or weaknesses of APIs, such as authentication, authorization, encryption, rate limiting, or input validation5. The requests in the question do not target any specific API functionality or feature.
* D. Directory traversal. This is the correct answer, because directory traversal is an attack that exploits insufficient security validation or sanitization of user-supplied file names, such that characters representing “traverse to parent directory” are passed through to the operating system’s file system API12. The requests in the question contain various patterns of …/ or / characters that attempt to access restricted files and directories on the server.

- A. High availability
- B. Application security
- C. Segmentation
- D. Integration and auditing
High availability refers to the ability of a system or service to remain operational and available to users with minimal downtime. By ensuring high availability, the company can maintain good performance and ensure that users have access to the network services they need. High availability can also improve security, as it helps to prevent disruptions that could potentially be caused by security incidents or other issues.
