Data Integrity

5 minutes 5 Questions

Data Integrity refers to the assurance that data remains accurate, consistent, and reliable during its entire life cycle. This security concept is crucial because compromised data integrity may lead to incorrect decision-making or unauthorized modifications to the data, causing serious consequences for an organization. Data integrity can be achieved through several methods, including access controls, error detection and correction algorithms, hashing, checksums, and digital signatures. Ensuring data integrity not only offers protection from unauthorized changes but also validates the reliability and credibility of the data. Data integrity is an important aspect of overall data security, as it helps maintain trust in the organization's information and systems.

Guide on Data Integrity for CompTIA Security Plus Exam

Data Integrity is a crucial concept in the field of Information Security. It refers to the accuracy, consistency, and reliability of data during any operation (creation, update, transmission etc). Here is what you need to know:
Importance:
- Data integrity ensures information has not been altered during its lifecycle.
- It preserves the consistency & trustworthiness of data over its entire lifecycle.
- It safeguards data quality and prevents unauthorized access or modification.
How it works:
1. Data should remain consistent and unchanged during transit.
2. Data should not be altered or corrupted by unauthorized entities.
3. Use of checksums, hashing algorithms, digital signatures, and other means for verification.
Exam Tips: Answering Questions on Data Integrity
- Understand the concept deeply instead of just remembering the definition.
- Know the difference between data integrity and data security.
- Understand the role of hashing, checksums, and digital signatures in maintaining data integrity.
- Look for any signs of data alteration or damage in given scenarios.
- Practice lots of questions to gain a better understanding of the concept and how it works in practice.

Question 1

An attacker manipulates a database to reflect a different balance for their account in an online banking system. Which aspect of data integrity has been compromised?

Non-repudiation Availability Accuracy Authenticity

Correct Answer: Accuracy

Accuracy, the correct answer, is compromised when an attacker manipulates data to reflect false information. The other options deal with different aspects of data integrity, but none specifically address misleading data that results from malicious manipulation.

Question 2

A company is moving their operations to the cloud, and they want to ensure the integrity of their data. Which of the following would be the BEST choice?

Disable multi-factor authentication for cloud services. Avoid encryption when data is in transit between their servers and the cloud. Use plaintext passwords for easier maintenance. Implement a cloud-access security broker (CASB) and configure file integrity monitoring.

Correct Answer: Implement a cloud-access security broker (CASB) and configure file integrity monitoring.

The correct answer, implementing a cloud-access security broker (CASB) and configuring file integrity monitoring, ensures that data integrity is consistently maintained. The other choices either promote poor security practices or neglect data integrity.

Question 3

An employee receives an unexpected email containing a signed invoice for services that were never provided. Which security mechanism failed in ensuring data integrity?

Hashing Non-repudiation Encryption Multi-factor authentication

Correct Answer: Non-repudiation

Non-repudiation prevents a party from denying the authenticity of their actions, such as sending an invoice for services never provided. The incorrect answers involve protecting data from unauthorized access or ensuring that data is not tampered with or leaked.
