Answer 17

Metasploit is an open-source platform that provides a collection of tools and exploits to simulate real-world attacks and assess the security of systems and networks.

Question 18

What is the difference between symmetric and asymmetric cryptography?

Answer 18

Symmetric cryptography uses a single key for both encryption and decryption, while asymmetric cryptography uses a pair of keys (public and private) for encryption and decryption.

Question 19

What are the advantages of elliptic curve cryptography (ECC) over RSA?

Answer 19

ECC provides stronger security with shorter key lengths, resulting in faster computations, lower power consumption, and reduced storage and transmission requirements.

Question 20

What is the purpose of a key exchange protocol, such as Diffie-Hellman?

Answer 20

Key exchange protocols allow two parties to establish a shared secret key over an insecure communication channel without prior knowledge of each other.

Question 21

What is the difference between a stream cipher and a block cipher?

Answer 21

A stream cipher encrypts data one bit or byte at a time, while a block cipher encrypts fixed-size blocks of data (e.g., 64 or 128 bits) at a time.

Question 22

What is the purpose of a message authentication code (MAC) in cryptography?

Answer 22

A MAC ensures the integrity and authenticity of a message by generating a small piece of data that is computed using a secret key and appended to the message.

Question 23

What is the difference between collision and preimage resistance in cryptographic hash functions?

Answer 23

Collision resistance means it is computationally infeasible to find two different inputs that produce the same hash output, while preimage resistance means it is computationally infeasible to find an input that produces a given hash output.

Question 24

What is the purpose of a hardware security module (HSM) in cryptographic key management?

Answer 24

An HSM is a physical device that safeguards and manages digital keys, performs cryptographic operations, and provides tamper resistance and detection features.

Question 25

What is the concept of defense in depth in physical security?

Answer 25

Defense in depth involves using multiple layers of security controls, such as perimeter protection, access control, surveillance, and intrusion detection, to create a comprehensive security posture.

Question 26

What are the three main types of physical access control systems?

Answer 26

Discretionary access control (DAC), mandatory access control (MAC), and role-based access control (RBAC).

Question 27

What is the purpose of a mantrap in physical security?

Answer 27

A mantrap is a physical access control system that consists of two interlocking doors, allowing only one person to pass through at a time and preventing tailgating.

Question 28

What are the advantages of using biometric authentication for physical access control?

Answer 28

Biometric authentication provides a high level of security, eliminates the need for physical tokens or passwords, and offers non-repudiation.
