Your company hosts multiple web applications in AWS EC2 and the AWS WAF service is used to protect the applications against the attacks in the HTTP(S) layer 7
To meet the company's security policies, you need to ensure that the same protection rules are applied for all the WAF ACLs.
Which of the following would help to achieve this requirement?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer - B.
Option A is incorrect because there is no need to purchase rules in AWS Marketplace.
This is not a cost-efficient method.
Option B is CORRECT because rule groups in AWS WAF can be created with the required conditions that are used for all the WAF ACLs.
Option C is incorrect because AWS WAF does not have the concept of the template.
Rule groups should be used in this scenario.
Option D is incorrect because WAF rule groups should be created with the required conditions.
For any WAF ACL, you can apply the rule groups.
The requirement is to ensure that the same protection rules are applied to all the AWS WAF ACLs protecting multiple web applications hosted in AWS EC2. AWS WAF is a web application firewall service that helps protect web applications from attacks by inspecting the incoming web traffic and applying rules to block or allow the traffic based on the rules defined.
To meet the requirement, the recommended approach is to use a centrally managed set of rules that can be applied to all the WAF ACLs protecting the web applications.
Let's look at the options provided:
A. Purchase managed rule groups in AWS Marketplace and configure all WAF ACLs to use the rule groups. This option suggests purchasing managed rule groups from AWS Marketplace and configuring all WAF ACLs to use the same rule groups. This would ensure that the same set of rules are applied to all WAF ACLs, and any updates or changes made to the rule groups would be applied consistently across all ACLs. This is a good option, but the cost and effectiveness of the managed rule groups would depend on the specific needs of the organization.
B. Create custom rule groups in AWS WAF and configure all WAF ACLs to use the rule groups. This option suggests creating custom rule groups in AWS WAF and configuring all WAF ACLs to use the same custom rule groups. This option would also ensure that the same set of rules are applied to all WAF ACLs, and any updates or changes made to the rule groups would be applied consistently across all ACLs. This is a good option if the organization has specific rules that are unique to its applications.
C. Create a WAF template that contains the required rules. Use the template for the WAF ACLs. This option suggests creating a WAF template that contains the required rules and using the template for all WAF ACLs. This option would also ensure that the same set of rules are applied to all WAF ACLs, and any updates or changes made to the template would be applied consistently across all ACLs. This is a good option if the organization wants to ensure consistent configuration across all its AWS WAF instances.
D. Create the WAF conditions that include the required rules. Apply the conditions in all the WAF ACLs. This option suggests creating WAF conditions that include the required rules and applying the conditions to all WAF ACLs. This option would also ensure that the same set of rules are applied to all WAF ACLs, but any updates or changes made to the conditions would need to be applied to all ACLs separately. This option is not as efficient as the other options provided.
In summary, options A, B, and C are all viable options for meeting the requirement of ensuring that the same protection rules are applied to all AWS WAF ACLs. Depending on the specific needs of the organization, any of these options could be used to achieve the desired outcome.
