Q & A

What are the four main principles of information security discussed in the video?

The four main principles of information security are: Availability, Integrity, Confidentiality, and Authenticity.

What does the principle of Availability mean in the context of information security?

The principle of Availability ensures that information and systems are accessible and operational whenever needed to support business processes.

How does Integrity protect data in information security?

Integrity ensures that information is protected from unauthorized changes and alterations, maintaining its accuracy as originally stored.

What is the main focus of the Confidentiality principle in information security?

Confidentiality focuses on ensuring that information is only accessible to authorized individuals, protecting it from unauthorized access or disclosure.

What does the Authenticity principle guarantee in information security?

Authenticity guarantees that the information is genuine, trustworthy, and comes from a reliable source, ensuring the data has not been tampered with.

How is Cryptography related to the principles of information security?

Cryptography helps protect information by using algorithms, hashes, and digital signatures. It supports the principles of confidentiality, integrity, and authenticity by securing data during storage, transmission, and processing.

What is meant by 'data in transit' and how does cryptography protect it?

'Data in transit' refers to data being exchanged or communicated between parties. Cryptography protects this data by ensuring it remains confidential, untampered, and authentic during transmission.

In what way does the principle of Integrity ensure data accuracy?

Integrity ensures that data remains unchanged during storage, transmission, or processing, meaning it is delivered exactly as it was originally intended, without unauthorized modifications.

What are the potential consequences of breaching the principle of Confidentiality?

A breach of confidentiality can lead to unauthorized access to sensitive information, resulting in privacy violations, financial loss, legal consequences, and damage to an organization's reputation.

Why is it important to understand the relationship between the four principles of information security?

Understanding the relationship between the four principles—Availability, Integrity, Confidentiality, and Authenticity—is crucial for implementing effective security measures that protect data from threats and ensure the smooth operation of business processes.
