Final answer:
AWS Web Application Firewall (WAF) is a web application firewall, and AWS Shield is a managed DDoS protection service with two tiers: Standard and Advanced. They are distinct services that provide different levels of protection. AWS WAF allows customizable web security rules, while AWS Shield offers DDoS protection.
Step-by-step explanation:
The correct statements that describe the main roles of AWS Web Application Firewall (WAF) and AWS Shield are not specified in the provided options. However, there is key information about these services that can be addressed:
- AWS WAF is a web application firewall that helps protect web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources.
- AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that is intended to safeguard applications running on AWS.
AWS Shield comes in two tiers: Standard and Advanced. AWS Shield Standard provides basic DDoS protection for all AWS customers at no extra charge and includes protection against most common, frequently occurring network and transport layer DDoS attacks. On the other hand, AWS Shield Advanced provides additional protection against more sophisticated and larger DDoS attacks and offers access to advanced support teams.
AWS WAF and AWS Shield Advanced can be used together to provide a more comprehensive security solution. AWS WAF gives you control over which traffic to allow or block to your web applications by defining customizable web security rules, while AWS Shield Advanced provides extra DDoS protection for those applications on top of the capabilities offered by AWS Shield Standard.
- AWS WAF and AWS Shield are typically separate services with integrated functionalities that can be used in tandem for enhanced security.
- Statement E incorrectly identifies AWS WAF as including AWS Shield, but in fact, they are distinct services with different purposes and applications.
