NEW QUESTION 2
During a recent security assessment, a vulnerability was found in a common OS. The OS vendor was unaware of the issue and promised to release a patch within the next quarter. Which of the following best describes this type of vulnerability?
- A. Legacy operating system
- B. Weak configuration
- C. Zero day
- D. Supply chain
A zero-day vulnerability is a security flaw that is unknown to the vendor and the public, and therefore has no patch or fix available. A zero-day attack is an exploit that takes advantage of a zero-day vulnerability before the vendor or the security community becomes aware of it. A zero-day attack can cause serious damage to a system or network, as there is no defense against it until a patch is released. References:

NEW QUESTION 6
A company recently suffered a breach in which an attacker was able to access the internal mail servers and directly access several user inboxes. A large number of email messages were later posted online. Which of the following would bast prevent email contents from being released should another breach occur?
- A. Implement S/MIME to encrypt the emails at rest.
- B. Enable full disk encryption on the mail servers.
- C. Use digital certificates when accessing email via the web.
- D. Configure web traffic to only use TLS-enabled channels.
S/MIME stands for Secure/Multipurpose Internet Mail Extensions, which is a standard for encrypting and digitally signing email messages. S/MIME can provide confidentiality, integrity, authentication and
non-repudiation for email communications. S/MIME can encrypt the emails at rest, which means that the
email contents are protected even if they are stored on the mail servers or the user inboxes. S/MIME can prevent email contents from being released should another breach occur, as the attacker would not be able to decrypt or read the encrypted emails without the proper keys or certificates.

NEW QUESTION 12
An organization experiences a cybersecurity incident involving a command-and-control server. Which of the following logs should be analyzed to identify the impacted host? (Select two).
- A. Application
- B. Authentication
- C. Error
- D. Network
- E. Firewall
- F. System
Network and firewall logs should be analyzed to identify the impacted host in a cybersecurity incident involving a command-and-control server. A command-and-control server is a central server that communicates with and controls malware-infected devices or bots. A command-and-control server can send commands to the bots, such as downloading additional malware, stealing data, or launching attacks. Network logs can help to identify any suspicious or anomalous network traffic, such as connections to unknown or malicious domains, high-volume data transfers, or unusual protocols or ports. Firewall logs can help to identify any blocked or allowed traffic based on the firewall rules, such as connections to or from the command-and-control server, or any attempts to bypass the firewall.

- A. Content filter
- B. SIEM
- C. Firewall rules
- D. DLP
A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. The systems analyst can use firewall rules to block connections from the ten IP addresses in question, or from the entire network block in the specific country. This would be a quick and effective way to address the issue of high connections to the web server initiated by these IP addresses.

- A. Whaling
- B. Spam
- C. Invoice scam
- D. Pharming
A social engineering attack that relies on an executive at a small business visiting a fake banking website where credit card and account details are harvested is known as whaling.

NEW QUESTION 15
A security analyst is reviewing the output of a web server log and notices a particular account is attempting to transfer large amounts of money:
Which of the following types of attacks is most likely being conducted?
- A. SQLi
- B. CSRF
- C. Spear phishing
- D. API
CSRF stands for Cross-Site Request Forgery, which is an attack that forces an end user to execute unwanted actions on a web application in which they are currently authenticated1. In this case, the attacker may have tricked the user into clicking a malicious link or visiting a malicious website that sends forged requests to the web server of the bank, using the user’s session cookie or other credentials. The web server then performs the money transfer requests as if they were initiated by the user, without verifying the origin or validity of the requests.
* 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 execution2. The output of the web server log does not show any SQL statements or commands.
* B. CSRF. This is the correct answer, because CSRF 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 credentials1. The output of the web server log shows multiple GET requests with different account numbers and amounts, which may indicate a CSRF attack.
* C. Spear phishing. This is not the correct answer, because spear phishing is an attack that targets a specific individual or organization with a personalized email or message that contains a malicious link or attachment3. The output of the web server log does not show any email or message content or headers.
* D. API. 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 is not an attack method, but rather a way of designing and developing software applications.
