Question 21

A financial institution is implementing a User and Entity Behavior Analytics (UEBA) system to enhance its security posture. The system is designed to analyze user behavior patterns and detect anomalies that may indicate potential insider threats or compromised accounts. During the initial phase, the UEBA system collects baseline data from 1,000 users over a period of 30 days, focusing on metrics such as login times, access frequency to sensitive data, and transaction volumes. After the baseline is established, the system identifies that 5% of users exhibit behavior that deviates significantly from the established norms. If the institution decides to investigate these anomalies further, what is the expected number of users that will require deeper analysis, and what considerations should the security team take into account regarding the implications of false positives and regulatory compliance?

Accepted Answer

50 users; the team should ensure compliance with GDPR and consider the potential impact of false positives on user trust and operational efficiency.

Question 22

In a corporate environment, an organization implements a Safe Links feature to protect its employees from malicious URLs in emails. The IT department needs to evaluate the effectiveness of this feature by analyzing the number of malicious links detected over a month.

Question 25

In a corporate environment, a security analyst is tasked with evaluating the effectiveness of an Advanced Threat Analytics (ATA) system that utilizes machine learning algorithms to detect anomalies in network traffic. The analyst observes that the system has flagged 150 out of 10,000 network events as potential threats. Upon further investigation, it is found that 120 of these flagged events were indeed true positives, while 30 were false positives. The analyst needs to calculate the precision and recall of the ATA system to assess its performance. What is the correct interpretation of these metrics in the context of the ATA system\'s effectiveness?

Accepted Answer

The precision is 0.8 and the recall is 0.8, indicating a balanced performance in identifying true threats while minimizing false alarms.

Question 26

In a corporate environment, an organization is implementing a multi-factor authentication (MFA) system to enhance security for accessing sensitive data. The system requires users to provide two or more verification factors to gain access. If the organization decides to use a combination of something the user knows (password), something the user has (a smartphone app for generating time-based one-time passwords), and something the user is (biometric verification), what is the minimum number of factors required for the MFA system to be considered compliant with the NIST SP 800-63 guidelines for identity assurance?

Accepted Answer

Question 27

A financial institution is implementing a Security Configuration Management (SCM) program to ensure compliance with the Payment Card Industry Data Security Standard (PCI DSS). The institution has identified several systems that require configuration hardening. The systems include a web server, a database server, and an application server. Each server has a different baseline configuration requirement based on its role. The web server must have specific ports closed, the database server must have encryption enabled for data at rest, and the application server must have logging enabled for all access attempts. If the institution conducts a risk assessment and determines that the likelihood of a security breach is 0.2 (20%) for the web server, 0.1 (10%) for the database server, and 0.15 (15%) for the application server, what is the overall risk score for the institution if the impact of a breach on the web server is rated at 5, the database server at 8, and the application server at 6?

The institution has scored 28 points in Risk Management, 20 points in Reporting and Recordkeeping, and 25 points in Customer Due Diligence. What is the institution\'s overall compliance score, and how does it compare to the minimum compliance threshold of 70 points?

Accepted Answer

73 points

Question 29

A large organization is implementing Privileged Identity Management (PIM) to enhance its security posture. The organization has 500 users, of which 50 are designated as privileged users who require elevated access to critical systems. The PIM solution is designed to enforce just-in-time (JIT) access, meaning that privileged access is granted only when necessary and for a limited duration. If the organization decides to implement a policy that allows each privileged user to request access for a maximum of 4 hours per session, and each user can request access up to 3 times a week, what is the maximum number of hours of privileged access that can be granted to all privileged users in a single week?

Accepted Answer

600 hours
