Cybersecurity is the confidentiality, reliability, and availability of an

information.

T F $2.$ Cybersecurity and network security are subsets of Information security.

T F $3.$ Encrypted version of cyphertext is a plaintext.

T F $4.$ Asymmetric Cryptography is also called Private key Cryptography.

T F $5.$ Integrity is provided with two$-$way hash functions and digital signatures.

T F $6.$ Diffusion is an approach to encryption by spreading out the influence of one

cleartext letter over many ciphertext letters.

T F $7.$ Ciphertext is the scrambled and unreadable output of encryption

T F $8.$ Cryptographic process involves algorithms and increasingly complex keys.

T F $9.$ The main objective of Cryptography is to protect the integrity and

Availability of data.

T F $10.$ Steganography is the hiding of a secret message within an ordinary message

and the extraction of it at its destination.
