In a tech startup, Kabir is responsible for implementing security measures for their cloud service. He decides to use public-key cryptography for key exchange and symmetric cryptography for bulk encryption. Why is this approach preferred?

In a cloud application, Arnav receives data that is encrypted but is actually sent by an impostor pretending to be his colleague. This situation demonstrates the failure of authentication but not confidentiality. Which option best describes this scenario?

Myra is sending a confidential document to Tara that requires both integrity and non-repudiation. In digital signatures, which combination should she use to ensure these requirements are met?

Rohan and Ishika are conducting an online transaction for a service. To ensure that neither of them can deny the transaction later, they rely on a financial institution that guarantees this protection. What service is being enforced?

In a digital communication scenario, Sanya sends a confidential report to Nikita. To ensure that the report has not been altered during transmission, which of the following pairs best differentiates Integrity from Authentication?

Aashi is tasked with encrypting large cloud datasets for her company's new project. She needs to choose the most efficient encryption method to ensure data security. Which option should she select?

Avyaan is trying to secure his online messages and wants to use a cryptographic function that is one-way and non-reversible. Which function should he choose?

In a cloud storage system, Aditi has stored sensitive encrypted data. One day, she notices that the data has been altered. How will the system detect this alteration?

A cloud provider implements TLS 1.3 with ECDHE and AES-GCM. This combination ensures:

Which scenario shows authentication without confidentiality?

Saisha is sending a confidential report to her manager via email. If confidentiality is ensured but authentication fails, what is the risk?

Which scenario best demonstrates the failure of integrity in cloud security?

Aisha is developing a cloud application that uses only symmetric-key encryption to secure communication between clients and the server. She is aware of various security challenges that come with this approach. Which of the following is the MOST significant security challenge she might face?

Imagine Riyaan sends a confidential message to Asher using a cloud service that only implements message authentication codes (MACs). What limitation remains in this scenario?

A healthcare SaaS provider, HealthSecure, stores sensitive healthcare records for various clinics. They encrypt the records with AES-256 and use RSA only during login to exchange the session key. Which security service is MOST directly dependent on RSA in this system?

In a modern tech company, Shreya is implementing a cloud authentication system that uses digital signatures for login verification instead of traditional passwords. Which advantage does this provide over password-based login?

Dr. Aditi uploads a patient’s report to a cloud data-sharing system. To ensure that she cannot later deny uploading it, which cryptographic method is MOST suitable?

A cloud API requires that only applications signed by the developer can interact with sensitive services. In a real-world scenario, Ananya is developing a mobile application that needs to access sensitive user data stored in the cloud. To ensure that only her application can access this data, she implements a security measure that mandates all interactions with the cloud API must be signed with her developer credentials. Which combination of security services is achieved here?

During a data transmission between a cloud provider and a client, the provider uses asymmetric encryption exclusively, without integrating symmetric encryption. What is the MAIN drawback of this approach?
