Ensuring the confidentiality of transmitted information is crucial to protect data from unauthorized access during transmission. Here ' s an analysis of the provided options:

A. Firewall:

A firewall monitors and controls incoming and outgoing network traffic based on predetermined security rules. While it helps prevent unauthorized access to or from a private network, it doesn ' t encrypt the data being transmitted. Therefore, it doesn ' t ensure the confidentiality of the data during transmission.

B. Antivirus Software:

Antivirus software is designed to detect, prevent, and remove malicious software. It protects the system from malware but doesn ' t play a role in securing the confidentiality of data during transmission.

C. Passwords:

Passwords are used to authenticate users and control access to systems and data. While they help ensure that only authorized users can access certain information, they don ' t protect data during transmission from interception or eavesdropping.

D. Encryption:

Encryption involves converting plaintext data into a coded form (ciphertext) that is unreadable to unauthorized parties. Only those possessing the correct decryption key can convert the data back into its original form. By encrypting data before transmission, even if the data is intercepted, it remains unintelligible without the decryption key, thereby ensuring confidentiality. Encryption is widely recognized as one of the most effective methods for protecting data confidentiality during transmission.

In conclusion, among the options provided, encryption is the most effective control for ensuring the confidentiality of transmitted information, making option D the correct answer.

The auditor likely omitted the data normalization step, which is crucial when integrating multiple datasets from different sources (e.g., human resources (HR) and payroll). Without normalization, inconsistencies in formatting, naming conventions, or unique identifiers (e.g., employee ID vs. full name) can result in incorrect mismatches.

Standardization of Data Formats:

Employee names or IDs may be stored differently across systems (e.g., " John A. Doe " in HR vs. " Doe, John " in payroll).

Normalization ensures uniform formatting to enable accurate comparisons.

Removal of Duplicates & Inconsistencies:

Employee records could have multiple variations due to typos, abbreviations, or missing fields.

Proper cleaning and transformation of data ensures better accuracy.

Use of Unique Identifiers:

Instead of matching by name, the auditor should have used a unique identifier (e.g., Employee ID), which remains constant across systems.

A. Data analysis (Incorrect)

Reason: The auditor did attempt data analysis (matching employee records) but without proper preparation (normalization), the results were flawed.

B. Data diagnostics (Incorrect)

Reason: Data diagnostics refers to evaluating data quality issues, but it does not involve transforming data to a common format, which was the missing step.

C. Data velocity (Incorrect)

Reason: Data velocity relates to the speed at which data is processed, which is not relevant to the issue of incorrect matching.

Why is Data Normalization Important?Analysis of Incorrect Answers:IIA References:Thus, the correct answer is D. Data normalization.

Remote wipe is a security feature used in mobile device management (MDM) that allows an organization to erase data from a device remotely. This is critical in cases where a device is lost, stolen, or compromised, ensuring that sensitive corporate data is protected.

(A) It can restore default settings and lock encrypted data when necessary.

Partially correct but not the best answer. Remote wipe does erase data but does not necessarily lock encrypted data unless additional security features are enabled.

(B) It enables the erasure and reformatting of secure digital (SD) cards.

Incorrect. Many remote wipe solutions do not erase external SD cards due to hardware limitations. Users often need separate encryption for SD card data.

(C) It can delete data backed up to a desktop for complete protection if required.

Incorrect. Remote wipe only affects the device itself; it cannot erase backups stored on a desktop or local drives.

(D) It can wipe data that is backed up via cloud computing. ✅

Correct. Many MDM solutions offer the ability to remove access to corporate cloud data, revoke credentials, and remotely erase cloud-stored business files (such as OneDrive, Google Drive, or iCloud backups).
