✍️ Sample Cyber Security Questions & Answers

1. What does the term 'dwell time' refer to in a security incident?
✓ The duration an attacker remains undetected inside a compromised network

Dwell time is the period between initial compromise and detection, during which attackers can freely operate.

2. What does the principle of separation of duties prevent in access management?
✓ A single individual from having enough access to commit and conceal fraud

Separation of duties requires multiple people to complete sensitive tasks, preventing any one person from both initiating and approving a transaction.

3. What is an access token in OAuth 2.0 used for?
✓ Authorizing an application to access resources on behalf of a user

An OAuth 2.0 access token grants an application permission to access specific resources without exposing user credentials.

4. What is memory forensics used to uncover during incident response?
✓ Running processes, injected code, and encryption keys in volatile RAM

Memory forensics analyzes a RAM dump to find running processes, malware artifacts, and data that never touches disk.

5. What is Cross-Site Request Forgery (CSRF)?
✓ An attack that tricks authenticated users into unknowingly submitting malicious requests

CSRF tricks an authenticated user's browser into sending an unintended request to a trusted site, exploiting the site's trust in the user's session.

6. What does the principle of least privilege mean in cloud IAM?
✓ Grant users only the minimum permissions needed to perform their job functions

Least privilege limits the blast radius of compromised accounts by granting only the permissions necessary for a user's role.
