CIA IIA-CIA-Part3 Release Date

Authorization controls ensure that users have appropriate access levels based on their roles and responsibilities. The primary concern arises when all users have uniform access, as it violates the principle of least privilege (PoLP) and increases the risk of unauthorized access and data breaches.

(A) Users can only see certain screens in the system.

Incorrect. This is a good security practice, as it limits user access based on job roles, preventing unauthorized access to sensitive information.

(B) Users are making frequent password change requests.

Incorrect. Frequent password resets might indicate poor password management but are not directly related to authorization controls.

(C) Users input incorrect passwords and get denied system access.

Incorrect. This indicates authentication issues, not an authorization control concern. If users are denied access due to incorrect passwords, the system’s authentication mechanisms are working correctly.

(D) Users are all permitted uniform access to the system. ✅

Correct. Authorization should be role-based, meaning different users should have different levels of access depending on their responsibilities. Uniform access violates security best practices and increases the risk of fraud, data misuse, and compliance violations.

IIA GTAG "Identity and Access Management" emphasizes that authorization controls should be based on job functions to prevent unnecessary exposure to sensitive data.

IIA Standard 2120 – Risk Management highlights the importance of access control policies to mitigate cybersecurity risks.

Analysis of Answer Choices:IIA References:Thus, the correct answer is D, as uniform access across all users is a major security concern in authorization control.

Understanding Spear Phishing Attacks:

Spear phishing is a targeted cyberattack where attackers send personalized emails to trick individuals into providing sensitive data (e.g., passwords, financial information).

Unlike regular phishing, which casts a wide net, spear phishing is highly customized and often appears to come from a trusted source.

Why Option C Is Correct?

The scenario describes a highly personalized email (related to a golf membership) that tricks the recipient into clicking a malicious hyperlink and entering sensitive data.

This matches the definition of a spear phishing attack, where an attacker tailors a scam specifically for an individual.

IIA GTAG 16 – Data Analytics and ISO 27001 emphasize the need for security awareness training to mitigate such threats.

Why Other Options Are Incorrect?

Option A (Website attack causing a server crash):

This describes a Denial-of-Service (DoS) attack, not spear phishing.

Option B (Generic recorded message requesting password data):

This is vishing (voice phishing), not spear phishing. Spear phishing relies on personalized emails.

Option D (Fake social media investment opportunity):

This describes mass phishing, which targets multiple users, unlike spear phishing, which is highly targeted.

Spear phishing is a targeted attack that uses personal details to deceive individuals, making option C the best choice.

IIA GTAG 16 and ISO 27001 emphasize cybersecurity awareness to prevent such attacks.

Definition of Predictive Analytics:

Predictive analytics uses historical data, machine learning, and statistical algorithms to forecast future outcomes.

In the healthcare sector, it is used to predict patient readmission rates and identify those at high risk of needing additional treatment.

How Predictive Analytics Applies to Hospitals:

Hospitals analyze patient histories, symptoms, treatments, and recovery rates to determine the likelihood of readmission.

Predictive models help healthcare providers take proactive measures, such as tailored post-discharge care plans, to reduce readmission risks.

This leads to better patient outcomes and cost savings.

Why Other Options Are Incorrect:

B. Prescriptive analytics:

Prescriptive analytics goes beyond prediction and provides recommendations for action. In this case, the hospital is only determining which patients are likely to require additional treatment, not recommending treatments.

C. Descriptive analytics:

Descriptive analytics focuses on summarizing past data without making predictions. It would be used to report on past patient admissions but not to predict future readmissions.

D. Diagnostic analytics:

Diagnostic analytics analyzes the causes of past events but does not forecast future patient readmissions.

IIA’s Perspective on Data Analytics in Decision-Making:

IIA GTAG (Global Technology Audit Guide) on Data Analytics emphasizes the role of predictive analytics in risk assessment and operational efficiency.

COSO ERM Framework supports predictive modeling as part of strategic risk management.

Importance of Secure Protocols for Web Server Management:

Web servers handle sensitive data, including user credentials, financial information, and confidential communications.

Using secure protocols like HTTPS, SFTP, and TLS-encrypted SMTP ensures data is encrypted and protected from cyber threats.

Risks of Clear-Text Protocols (HTTP & FTP):

HTTP (Hypertext Transfer Protocol) and FTP (File Transfer Protocol) transmit data in plaintext, making them vulnerable to man-in-the-middle (MITM) attacks, packet sniffing, and unauthorized access.

SFTP (Secure File Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) encrypt data, mitigating these risks.

Why Other Options Are Incorrect:

A. The file transfer protocol (FTP) should always be enabled – Incorrect.

FTP is not secure, and enabling it can expose the server to unauthorized file access and cyberattacks.

B. The simple mail transfer protocol (SMTP) should be operating under the most privileged accounts – Incorrect.

SMTP should operate with minimal privileges to reduce security risks in case of a breach.

C. The number of ports and protocols allowed to access the web server should be maximized – Incorrect.

Minimizing open ports and protocols reduces the attack surface and limits unauthorized access.

IIA’s Perspective on IT Security and Web Server Management:

IIA Standard 2110 – Governance requires organizations to establish secure IT practices, including encryption and secure protocols.

IIA GTAG (Global Technology Audit Guide) on IT Risks emphasizes minimizing security vulnerabilities by using encrypted communication.

ISO 27001 Security Standard recommends secure transmission protocols for protecting sensitive data.

ISO 27001 Security Standard – Data Encryption and Secure Transmission

Thus, the correct and verified answer is D. Secure protocols for confidential pages should be used instead of clear-text protocols such as HTTP or FTP.
