D Correct answer
Multiple choice

RSA is

  1. symmetric cryptosystem

  2. asymmetric cryptosystem

  3. block cypher

  4. digital signature
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

RSA is a widely used public-key cryptosystem that utilizes two different keys, a public key for encryption and a private key for decryption, making it an asymmetric cryptosystem.

Multiple choice

Verification of a login name and password is known as

  1. configuration

  2. accessibility

  3. authentication

  4. logging in
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Authentication is the process of verifying a user's identity, typically through login credentials like username and password. It's different from authorization (what permissions an authenticated user has) or accessibility (making systems usable by people with disabilities). Configuration refers to system settings, not identity verification.

Multiple choice

Verification of a login name and password is known as

  1. configuration

  2. accessibility

  3. authentication

  4. logging in

  5. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Authentication is the security process of verifying a user's identity before granting system access, typically through credentials like usernames and passwords. It's a critical first step in security, distinct from authorization which determines what an authenticated user can do.

Multiple choice

Firewalls are used to protect against

  1. unauthorised attacks

  2. virus attacks

  3. data driven attacks

  4. fire attacks

  5. all of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Firewalls are network security devices that monitor and control incoming and outgoing network traffic based on predetermined security rules. Their primary function is to protect against unauthorized access attempts and malicious network intrusions, not specifically viruses or data-driven attacks.

Multiple choice

Public key cryptography uses

  1. public and private keys

  2. public and shared keys

  3. internal and external keys

  4. open and closed keys
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Public key cryptography uses two keys: public key and private key. Information is encrypted by private key and decrypted by public key.

Multiple choice

How can we achieve information security in a network?

  1. By cryptography

  2. By addressing

  3. By layering

  4. By grade of service
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cryptography is a science of securing information in the network. It converts information into some other format which would not be understood by an unauthorized person.
