Understanding Security and Encryption

What is a security procedure?

• A set of established protocols and practices to protect assets and information from security threats.

• A framework for financial auditing and reporting.

• A guideline for marketing strategies and promotions.

• A method for training employees on customer service.

How can data be protected effectively in a school project where Prabakaran and Akmal are collaborating?

• Implement strong encryption and access controls.

• Disable all access controls for easier data retrieval.

• Store data in plain text without any security measures.

• Use weak passwords and share them widely.

Prabakaran is explaining encryption to his classmates. He describes it as a method of transforming data into a secure format that is unreadable without a decryption key. How would you define encryption in your own words?

• Encryption is the method of transforming data into a secure format that is unreadable without a decryption key.

• Encryption is the process of compressing data to save space.

• Encryption is the act of making data publicly accessible.

• Encryption is a technique used to speed up data transfer.

During a class discussion, Hanif asked, "What does decryption mean?"

• Decryption refers to the act of compressing data for storage.

• Decryption is the process of deleting data permanently.

• Decryption means creating encrypted data from its original form.

• Decryption means converting encrypted data back to its original form.

During a cybersecurity class, Akmal asked his teacher to explain asymmetric encryption.

• Asymmetric encryption is a technique that does not involve any keys for data security.

• Asymmetric encryption is a cryptographic technique that uses a pair of keys (public and private) for secure data transmission.

• Asymmetric encryption is a method that relies solely on symmetric keys.

• Asymmetric encryption uses a single key for both encryption and decryption.

In a secure messaging app, how does symmetric encryption work when juherna and danush send messages to each other?

• Symmetric encryption is a type of encryption that uses the same key for both encryption and decryption.

• Symmetric encryption uses different keys for encryption and decryption.

• Symmetric encryption is a type of encryption that only encrypts data but does not allow decryption.

• Symmetric encryption is a method that encrypts data without any keys.

How does encryption help in preventing data alteration in a school project where Faudzul and Zaid are collaborating on a sensitive document?

• Encryption makes data easier to access for everyone.

• Encryption helps prevent data alteration by making data unreadable and ensuring that unauthorized changes can be detected.

• Encryption allows anyone to modify data without detection.

• Encryption is only used for data storage, not for preventing changes.

During a class discussion, Izzul mentioned one advantage of using asymmetric encryption. Can you identify what he meant?

• It is faster than symmetric encryption for large data.

• It requires a shared secret key for encryption.

• It can only be used for encrypting small amounts of data.

• It enables secure key exchange without needing to share a secret key.

During a group project, Izzul, Kommala, and Zaid are discussing how to protect sensitive information shared online. What is a common use case for symmetric encryption?

• Storing passwords securely.

• Generating random keys for encryption.

• Encrypting data in transit.

• Securing data at rest.

Why is it important for Izzul and Jane to apply security procedures in their online project?

• To comply with outdated regulations that no longer apply.

• To ensure faster internet speeds for all users.

• It is important to apply security procedures to protect sensitive information and prevent unauthorized access.

• To make the system more user-friendly and accessible.
