Security Principles and Practices

True / False:

1. It is difficult to crack the Caesar cipher with a brute force attack
2. Spyware collects personal information about users without their knowledge
3. Symmetric encryption is faster than asymmetric encryption
4. Digital Signatures are used for securing a message

Answer 1

1. False. Caesar cipher can be cracked using brute force method.

2. True. A spyware collects information about a person or organization without their knowledge.

3. True. Symmetric encryption is faster than asymmetric encryption because it uses the same key for both encryption and decryption and hence takes less time to perform computations at the sender's and receiver's end.

4. True. Digital Signatures provide an additional layer of security by confirming the identity of sender and providing assurance to the receiver that sender is authentic and not an imposter.
