NEW QUESTION 8
The following are the logs of a successful attack.
Which of the following controls would be BEST to use to prevent such a breach in the future?
- A. Password history
- B. Account expiration
- C. Password complexity
- D. Account lockout
Answer: C
Explanation:
To prevent such a breach in the future, the BEST control to use would be Password complexity.
Password complexity is a security measure that requires users to create strong passwords that are difficult to guess or crack. It can help prevent unauthorized access to systems and data by making it more difficult for attackers to guess or crack passwords.
The best control to use to prevent a breach like the one shown in the logs is password complexity. Password complexity requires users to create passwords that are harder to guess, by including a mix of upper and lowercase letters, numbers, and special characters. In the logs, the attacker was able to guess the user's password using a dictionary attack, which means that the password was not complex enough. References:

- A. A red-team test
- B. A white-team test
- C. A purple-team test
- D. A blue-team test
Answer: A
Explanation:
A red-team test is a type of security assessment that simulates a real-world attack on an organization’s network, systems, applications, and people. The goal of a red-team test is to evaluate the organization’s security posture, identify vulnerabilities and gaps, and test the effectiveness of its detection and response capabilities. A red-team test is usually performed by a group of highly skilled security professionals who act as adversaries and use various tools and techniques to breach the organization’s defenses. A red-team test is often conducted without the knowledge or consent of most of the organization’s staff, except for a few senior executives who authorize and oversee the exercise.

NEW QUESTION 13
An incident has occurred in the production environment.
Analyze the command outputs and identify the type of compromise.
Solution:
Command Output1 = Logic Bomb
A logic bomb is a type of malicious code that executes when certain conditions are met, such as a specific date or time, or a specific user action1. In this case, the logic bomb is a script that runs every minute and checks if there is a user named john in the /etc/password file. If there is, it drops the production database using a MySQL command3. This could cause severe damage to the system and the data.
To prevent logic bombs, you should use antivirus software that can detect and remove malicious code, and also perform regular backups of your data. You should also avoid opening suspicious attachments or links from unknown sources, and use strong passwords for your accounts1.
Command Output2 = backdoorA backdoor is a type of malicious code that allows an attacker to access a system or network remotely, bypassing security measures1. In this case, the backdoor is a script that runs every time the date command is executed and prompts the user to enter their full name. Then, it opens a reverse shell connection using the nc command and downloads a virus file from a malicious website using the wget command2. This could allow the attacker to execute commands on the system and infect it with malware.
To prevent backdoors, you should use antivirus software that can detect and remove malicious code, and also update your system and applications regularly. You should also avoid executing unknown commands or scripts from untrusted sources, and use firewall rules to block unauthorized connections
Does this meet the goal?
- A. Yes
- B. Not Mastered
Answer: A

- C. Risk acceptance
- D. Risk matrix
Answer: A
Explanation:
A risk control self-assessment (RCSA) is a process that allows an organization to identify, evaluate, and mitigate the risks associated with its activities, processes, systems, and products. A RCSA involves asking relevant questions to assess the effectiveness of existing controls and identify any gaps or weaknesses that need improvement. A RCSA also helps to align the risk appetite and tolerance of the organization with its strategic objectives and performance.
The application development teams have been asked to answer questions related to their applications’ security posture, such as whether they receive patches from an external source, contain open-source code, are accessible by external users, or meet the corporate password standard. These questions are part of a RCSA process that aims to evaluate the potential risks and vulnerabilities associated with each application and determine how well they are managed and mitigated.
