Which AWS service helps manage access to AWS services and resources securely?
- A) AWS IAM
- B) AWS S3
- C) AWS RDS
- D) AWS EC2
Answer: A) AWS IAM
Explanation: AWS Identity and Access Management (IAM) enables secure control access to AWS services and resources.
True or False: It is not necessary to limit who can access PII within your organization.
- True
- False
Answer: False.
Explanation: Access to PII should be limited to those within the organization who have a necessary and legitimate business need to access the data.
Which of the following AWS services is commonly used for secure and compliance-friendly storage of PII data?
- A) AWS Glacier
- B) AWS Key Management Service
- C) AWS Macie
- D) AWS Identity and Access Management
Answer: C) AWS Macie
Explanation: AWS Macie uses machine learning to recognize sensitive data such as PII and provides dashboards and alerts that give visibility into how this data is being accessed or moved.
True or False: When destroying PII data in AWS, it is enough to simply delete the data.
- True
- False
Answer: False.
Explanation: To properly destroy PII data in AWS, you should implement secure deletion practices to ensure that the data cannot be restored or reconstructed.
You should use ___________ to protect data in transit.
- A) HTTP
- B) FTP
- C) URL encoding
- D) SSL/TLS
Answer: D) SSL/TLS
Explanation: SSL/TLS encrypts data in transit, helping to protect PII from potential eavesdropping or tampering during transmission.
Which AWS service can be used to monitor and log events in AWS environments for auditing purposes?
- A) AWS CloudTrail
- B) AWS KMS
- C) AWS IAM
- D) AWS S3
Answer: A) AWS CloudTrail
Explanation: AWS CloudTrail logs, continuously monitors and retains account activity related to actions across your AWS infrastructure, aiding in auditing and PII security.
True or False: In AWS Redshift, data is encrypted at rest by default.
- True
- False
Answer: True.
Explanation: In AWS Redshift, all data is encrypted and secure by default using hardware-accelerated AES-
When it comes to work with PII, what does the principle of “Least Privilege” mean?
- A) Giving users access to all data
- B) Only key personnel should have access privileges
- C) Users should have minimal privileges necessary to perform their job
- D) None of the above
Answer: C) Users should have minimal privileges necessary to perform their job.
Explanation: The principle of Least Privilege suggests that PII access within the organization should be limited to only those individuals who need access to perform their job.
Interview Questions
What is Personally Identifiable Information (PII)?
PII is information that can be used to identify, contact, or locate a single person, or to identify an individual in context.
How can PII be protected on AWS?
AWS provides several mechanisms to protect PII, including encryption at rest and in transit, access controls, identity and access management (IAM), and secure key management.
What is the importance of encrypting PII in AWS?
Encrypting data converts it into a format that can’t be read without the decryption key. This protects the data, including PII, from unauthorized access and is a key aspect of data security in AWS.
What role does access control play in protecting PII in AWS?
Access control decides who has access to PII, reducing the probability of unauthorized access. AWS provides IAM, which can be used to tightly control access to PII.
How does secure key management enhance the protection of PII in AWS?
AWS Key Management Service (KMS) creates and manages cryptographic keys. These keys are used to encrypt and decrypt PII stored in AWS services, effectively preventing unauthorized access.
What role does monitoring and logging play in the protection of PII on AWS?
Monitoring and logging provide visibility into access and usage patterns of PII. This allows detection of any unauthorized access or suspect activities, and helps in auditing for compliance purposes.
How can AWS S3 policies help protect PII?
AWS S3 policies can restrict who can access the data stored in a bucket. They can also enforce encryption of data at rest, providing another level of protection for PII.
What AWS service can be used for real-time analysis and alerting of suspicious activities related to PII?
This can be accomplished using Amazon GuardDuty. It continuously monitors for malicious activities and unauthorized behavior to protect PII and other sensitive data.
What AWS service can be used for compliance audits related to PII?
AWS CloudTrail can be used for the purpose. It provides event history of AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, and command-line tools.
How does AWS CloudHSM help protect PII?
AWS CloudHSM is a cloud-based hardware security module that enables key storage and cryptographic operations within a tamper-resistant hardware device. This further enhances the security of PII.
Can PII be identified using machine learning services provided by AWS?
Yes. AWS provides Amazon Macie, a security service that uses machine learning to automatically discover, classify, and protect sensitive data like PII.
How does data anonymization help protect PII on AWS?
Data anonymization makes it difficult to associate information with a particular individual, hence protecting PII. This can be done using data masking or tokenization.
Are there any certifications related to data protection on AWS that a Data Engineer can pursue?
Yes, certifications such as the AWS Certified Security – Specialty certification can be pursued for specialized knowledge in securing data on AWS.
What are the best practices for securing PII on AWS?
Common best practices include encrypting data at rest and in transit, managing access control via IAM, regularly rotating encryption keys, and regularly auditing and monitoring access patterns.
What service does AWS offer for secure document shredding?
While AWS does not offer document shredding, it does offer secure deletion services. AWS S3 objects, for example, can be securely deleted with the multi-factor authentication delete feature.
