Hey Tech Tobé family! This is part 3 of our 4 part series. I'm back this week with a four part series to test your understanding of what Cybersecurity is and to introduce it to those who are yet to be familiar with it.

Part three of our series introduces the CIA Triad—Confidentiality, Integrity, and Availability. These three principles form the foundation of cybersecurity practices. We’ll break down each component, explaining how they work together to secure digital environments.

Key Topics:

Confidentiality:

Ensuring that sensitive information is only accessible to those authorized to view it.

Examples: Encryption, access controls.

Integrity:

Maintaining the accuracy and trustworthiness of data by preventing unauthorized changes.

Examples: Checksums, version control systems.

Availability:

Guaranteeing that information and systems are accessible when needed by authorized users.

Examples: Redundancy, disaster recovery plans.

Practice Questions:

Which component of the CIA Triad ensures that data is not accessed by unauthorized individuals?

A) Confidentiality
B) Integrity
C) Availability
D) Authenticity

What does integrity in the CIA Triad ensure?

A) Data is available to authorized users when needed.
B) Data is not altered by unauthorized individuals.
C) Data is encrypted to prevent unauthorized access.
D) Data is backed up regularly.

Which of the following is an example of ensuring availability in the CIA Triad?

A) Using encryption to protect sensitive information.
B) Implementing access controls to restrict unauthorized users.
C) Setting up redundancy systems to ensure continuous access to data.
D) Using version control systems to maintain data accuracy.

Answers:

A) Confidentiality
B) Data is not altered by unauthorized individuals.
C) Setting up redundancy systems to ensure continuous access to data.
