PCIP Encryption Standards — Questions and Answers
Question 1: What is defense in depth in the context of PCIP security?
- Using one strong security control
- Implementing multiple layers of security controls (Correct answer)
- Focusing only on perimeter security
- Relying solely on encryption
Correct answer: Implementing multiple layers of security controls
Defense in depth uses multiple layers of security controls so that if one layer fails, additional layers continue to provide protection.
Question 2: Which principle states that users should only have access necessary for their role?
- Separation of duties
- Principle of least privilege (Correct answer)
- Need to share
- Defense in depth
Correct answer: Principle of least privilege
The principle of least privilege ensures users only have the minimum access rights needed to perform their job functions, limiting potential damage.
Question 3: In PCIP practice, what is the purpose of vulnerability scanning?
- To exploit systems
- To identify weaknesses before attackers do (Correct answer)
- To replace firewalls
- To slow down network traffic
Correct answer: To identify weaknesses before attackers do
Vulnerability scanning proactively identifies security weaknesses in systems and applications so they can be remediated before exploitation.
Question 4: What is the recommended response when a security incident is detected in an PCIP environment?
- Delete all logs immediately
- Follow the incident response plan: contain, eradicate, recover (Correct answer)
- Ignore minor incidents
- Immediately shut down all systems
Correct answer: Follow the incident response plan: contain, eradicate, recover
Following a structured incident response plan ensures containment of the threat, eradication of the cause, and recovery to normal operations.
Question 5: Which authentication factor is classified as "something you are"?
- Password
- Security token
- Biometric data (Correct answer)
- Smart card
Correct answer: Biometric data
Biometric data such as fingerprints, facial recognition, or retinal scans represents the "something you are" authentication factor.
Question 6: What is the primary purpose of encryption in PCIP security?
- To make data transfer slower
- To protect data confidentiality during storage and transmission (Correct answer)
- To compress data
- To organize data more efficiently
Correct answer: To protect data confidentiality during storage and transmission
Encryption protects data confidentiality by converting information into an unreadable format that can only be decoded with the proper key.
