Question # 1 An attacker recently gained unauthorized access to a financial institution's database, which contains confidential information. The attacker exfiltrated a large amount of data before being detected and blocked. A security analyst needs to complete a root cause analysis to determine how the attacker was able to gain access. Which of the following should the
analyst perform first?
A. Document the incident
and any findings related to the attack for future reference. B. Interview employees
responsible for managing the affected systems. C. Review the log files
that record all events related to client applications and user access. D. Identify the immediate actions that need to be taken to contain the incident and minimize
damage.
Click for Answer
C. Review the log files
that record all events related to client applications and user access.
Answer Description In a root cause analysis following unauthorized access, the initial step is usually to review relevant log files. These logs can provide critical information about how and when the attacker gained access. The first step in a root cause analysis after a data breach is typically to review the logs. This helps the analyst understand how the attacker gained access by providing a detailed record of all events, including unauthorized or abnormal activities. Documenting the
incident, interviewing employees, and identifying immediate containment actions are important steps, but they usually follow the initial log review.
Question # 2 A SOC analyst recommends adding a layer of defense for all endpoints that will better protect against external threats regardless of the device's operating system. Which of the following best meets this requirement?
A. SIEM B. CASB C. SOAR D. EDR
Click for Answer
D. EDR
Answer Description Explanation:
EDR stands for Endpoint Detection and Response, which is a layer of defense that monitors endpoints for malicious activity and provides automated or manual response capabilities. EDR can protect against external threats regardless of the device’s operating system, as it can detect and respond to attacks based on behavioral analysis and threat intelligence. EDR is also one of the tools that CompTIA CySA+ covers in its exam objectives. Official References:

C. All new employees must take a test about the company security policy during the
cjitoardmg process
D. All new employees must sign a user agreement to acknowledge the company security
policy
Click for Answer
D. All new employees must sign a user agreement to acknowledge the company security
policy
Answer Description The best action that the SOC manager can recommend to help ensure new employees are accountable for following the company policy is to require all new employees to sign a user agreement to acknowledge the company security policy. A user agreement is a document that defines the rights and responsibilities of the users regarding the use of the company’s systems, networks, or resources, as well as the consequences of violating the company’s security policy. Signing a user agreement can help ensure new employees are aware of and agree to comply with the company security policy, as well as hold them accountable for any breaches or incidents caused by their actions or inactions.

Question # 6 An organization has experienced a breach of customer transactions. Under the terms of PCI DSS, which of the following groups should the organization report the breach to? A. PCI Security
Standards Council B. Local law enforcement C. Federal law
enforcement D. Card issuer
Click for Answer
D. Card issuer
Answer Description Under the terms of PCI DSS, an organization that has experienced a breach of customer transactions should report the breach to the card issuer. The card issuer is the financial institution that issues the payment cards to the customers and that is responsible for authorizing and processing the transactions. The card issuer may have specific reporting requirements and procedures for the organization to follow in the event of a breach. The organization should also notify other parties that may be affected by the breach, such as customers, law enforcement, or regulators, depending on the nature and scope of the breach.

C. CSRF
Question # 8 An organization was compromised, and the usernames and passwords of all em-ployees were leaked online. Which of the following best describes the remedia-tion that could reduce the impact of this situation?
A. Multifactor
authentication B. Password changes C. System hardening D. Password encryption
Click for Answer
A. Multifactor
authentication
Answer Description Multifactor authentication (MFA) is a security method that requires users to provide two or more pieces of evidence to verify their identity, such as a password, a PIN, a fingerprint, or a one-time code. MFA can reduce the impact of a credential leak because even if the attackers have the usernames and passwords of the employees, they would still need another factor to access the organization’s systems and resources. Password changes, system hardening, and password encryption are also good security practices, but they do not address the immediate threat of compromised credentials.
