CySA+ Knowledge Areas Covered 1 — Questions and Answers
Question 1: Which of the following is primarily responsible for identifying vulnerabilities in an organization’s IT infrastructure?
- Incident response team
- Security operations center (SOC)
- Vulnerability management team (Correct answer)
- Digital forensics team
Correct answer: Vulnerability management team
The vulnerability management team is specifically tasked with systematically identifying, assessing, and prioritizing security weaknesses within an organization's IT infrastructure. They use tools and processes like vulnerability scanning and penetration testing to discover flaws before attackers can exploit them.
Question 2: What is the purpose of implementing security information and event management (SIEM) in a security operations center (SOC)?
- To encrypt sensitive data
- To monitor and respond to incidents in real-time (Correct answer)
- To conduct penetration testing on internal networks
- To patch software vulnerabilities automatically
Correct answer: To monitor and respond to incidents in real-time
Security Information and Event Management (SIEM) systems aggregate and analyze security logs and events from various sources across an organization's network. Their primary purpose in a SOC is to provide real-time monitoring, detect suspicious activities, and facilitate rapid incident response by alerting security analysts to potential threats.
Question 3: Which of the following best describes the concept of "least privilege" in security operations?
- Granting users only the minimal access necessary to perform their duties (Correct answer)
- Allowing administrative access to all users for troubleshooting
- Giving users access to all systems within the network
- Using the same password across multiple systems for simplicity
Correct answer: Granting users only the minimal access necessary to perform their duties
The principle of least privilege is a fundamental security concept that dictates users and systems should only be granted the minimum level of access required to perform their legitimate functions. This minimizes the potential damage if an account is compromised, as an attacker would only gain limited access.
Question 4: What should be the first step in the incident response process after identifying a potential security breach?
- Eradicate the malware
- Contain the incident to prevent further damage (Correct answer)
- Notify senior management
- Rebuild the affected systems
Correct answer: Contain the incident to prevent further damage
After identifying a security breach, the immediate priority in incident response is containment. This involves taking steps to limit the scope and impact of the incident, such as isolating affected systems or blocking malicious traffic, to prevent further damage or spread before full eradication and recovery can begin.
Question 5: A company is implementing an encryption solution to protect sensitive customer data. Which type of encryption would be most appropriate to secure data stored in the company’s database?
- Transport Layer Security (TLS)
- Full Disk Encryption (FDE)
- Database encryption (Correct answer)
- Public key infrastructure (PKI)
Correct answer: Database encryption
To protect sensitive customer data stored within a company's database, database encryption is the most appropriate solution. This method specifically encrypts data at rest within the database itself, providing a layer of security that protects information even if the underlying server or storage is compromised.
