Implementing application execution in a sandbox for unknown software is the best defense against this scenario. A sandbox is a isolated environment that can run applications or code without affecting or being affected by other processes or systems. A sandbox can prevent malicious software from accessing or modifying sensitive data or resources, as well as limit its network communication and system privileges. A sandbox can also monitor and analyze the behavior and output of unknown software to determine if it is benign or malicious.

The attacker in this scenario is using "Vishing" (Option D). Vishing stands for "voice phishing," and it involves a social engineering attack where an attacker makes phone calls, impersonates someone they are not, and tries to manipulate the victim into revealing sensitive information or taking specific actions, such as purchasing gift cards. In this case, the attacker is posing as the CEO and attempting to trick the employee over the phone.

A company purchased cyber insurance to address items listed on the risk register. This represents a transfer strategy. A transfer strategy involves transferring or sharing some or all of the responsibility or impact of a risk to another party, such as an insurer, a supplier, or a partner. A transfer strategy can help to reduce the financial liability or exposure of the company in case of a security incident or breach.

The web server logs are records of the requests and responses that occur between a web server and a web client, such as a browser. The web server logs can show where the malware originated by indicating the source IP address, the destination URL, the date and time, the HTTP status code, the user agent, etc., of each request and response. The web server logs can help the incident response team to trace back the malicious website that infected the host with malware.

The security engineer is an example of a data custodian. A data custodian is a person who is responsible for implementing and maintaining the security controls for the data, such as encryption, backup, access control, etc. A data custodian acts on behalf of the data owner, who is the person who has the authority and accountability for the data. A data controller is a person who determines the purposes and means of processing the data, such as a company or an organization. A data processor is a person who processes the data on behalf of the data controller, such as a service provider or a vendor1.

A program that allows individuals to security test the company’s internet-facing application and compensates researchers based on the vulnerabilities discovered is best described as a bug bounty program. A bug bounty program is an incentive-based program that rewards ethical hackers for finding and reporting security flaws in software or systems6.

Security awareness training is an administrative control that educates users on the best practices and policies for protecting the organization’s data and systems from various threats, such as malware, phishing, social engineering, etc. Security awareness training can reduce the occurrence of malware execution by increasing the users’ ability to recognize and avoid malicious links, attachments, downloads, or websites.

An employee receiving a gift card request in an email that has an executive’s name in the display field to the email describes a possible business email compromise attack. Business email compromise (BEC) is a type of phishing attack that targets employees who have access to financial or sensitive information, such as accounting, human resources, or executive staff. The attacker impersonates a trusted person, such as a manager, vendor, or client, and requests a fraudulent payment, wire transfer, gift card purchase, or personal information. The attacker may spoof the email address or display name, use a look-alike domain, or compromise a legitimate email account to make the request seem authentic.

The log files show that the attacker was able to access files and directories that were not intended to be accessible by web users, such as “/etc/passwd” and “/var/log”. This indicates that the attacker was able to exploit a vulnerability in the web server or application that allowed them to manipulate the file path and access arbitrary files on the server. This is a type of attack known as directory traversal, which can lead to information disclosure, privilege escalation, or remote code execution3.
