10 Questions

Which property ensures that data has not been altered without authorization?

A. Confidentiality B. Integrity C. Availability D. Non-repudiation

A system must encrypt a large amount of data efficiently, and both parties can securely share a secret key. Which approach is generally appropriate?

A. Symmetric encryption using a modern approved cipher B. Hashing the plaintext only C. Encoding with Base64 D. Using a digital signature as the only encryption method

Which key should a sender use to verify a digital signature created by a recipient?

A. The recipient's private key B. The sender's private key C. The signer's public key D. A shared database password

Why is a cryptographic hash useful for verifying a downloaded file?

A. It encrypts the file so nobody can read it B. It provides a digest that can be compared with a trusted reference C. It guarantees the file is harmless D. It replaces access control

What is a strong practice for protecting encryption keys?

A. Store keys alongside plaintext with broad access B. Use a controlled key-management system with restricted access, rotation, and audit C. Email private keys to all employees D. Reuse the same key indefinitely for every purpose

What is the primary role of a certificate authority in a public key infrastructure?

A. Issue and manage certificates that bind identities to public keys B. Store every user's plaintext password C. Encrypt all network traffic by itself D. Replace endpoint patching

A client receives a TLS certificate with a hostname mismatch. What should it do?

A. Ignore the mismatch and continue B. Reject or safely fail the connection unless the identity issue is resolved C. Disable certificate validation permanently D. Send credentials before checking the certificate

Which security objective is a digital signature primarily designed to support?

A. Authenticity and integrity, with potential non-repudiation depending on context B. Guaranteed availability C. Compression D. Anonymous network routing

Why should cryptographic keys be generated with a cryptographically secure random number generator?

A. Predictable keys are easier to remember B. Unpredictable keys reduce the chance that attackers can guess them C. Randomness removes the need for key storage controls D. It makes all algorithms quantum-proof

How should an application store user passwords?

A. As plaintext B. With a unique salt and a suitable password-hashing function such as Argon2id, scrypt, or bcrypt C. With reversible encryption using one shared key only D. In application logs
