Information Security Questions

Multiple choice

Which cloud security control is primarily used to detect and respond to security incidents?

  1. Encryption

  2. Multi-factor authentication

  3. Intrusion detection and prevention systems

  4. Data loss prevention
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Intrusion detection and prevention systems (IDPS) are cloud security controls that are used to detect and respond to security incidents. They monitor network traffic and system activity for suspicious or malicious behavior, and can take actions such as alerting security personnel, blocking malicious traffic, or isolating compromised systems.

Multiple choice

What is the purpose of implementing multi-factor authentication (MFA) in cloud security?

  1. To restrict unauthorized access to cloud resources

  2. To ensure data integrity and availability

  3. To detect and respond to security incidents

  4. To prevent sensitive data from being leaked or accessed by unauthorized individuals
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Multi-factor authentication (MFA) is a cloud security control that aims to restrict unauthorized access to cloud resources by requiring users to provide multiple forms of identification. This adds an extra layer of security, making it more difficult for attackers to gain access to cloud resources even if they have obtained one form of identification.
