In this short series, I outline the notes that I took while preparing for the AWS Cloud Practitioner exam.
These are my personal notes that I have made while working through the A Cloud Guru exam practitioner course. They are in no way official notes from AWS.
I would advise you that if you do use my notes to help you revise for this exam, that you use them as a supplement to the most recent information in the White Papers, Exam Guide and go over your knowledge with practice exam papers.

AWS Web Application Firewall (WAF) & AWS Shield
What is AWS WAF?
Helps protect your web application firewall from common web exploits that could affect your:
- Application availability
- Compromise security
- Consume excessive resources
- Will inspect the traffic coming into your application at layer 7
- It is placed in front of your firewall and will determine what goes through to your load balancer
What is AWS Shield?
- A managed Distributed Denial of Service (DDoS) mitigation (protection) service that safeguards web applications running on AWS
- Provides always-on detection and automatic inline mitigations that minimize application downtime and latency
- No need to engage AWS Support to benefit from DDoS protection
- Two tiers of AWS Shield:
- Standard (comes with all AWS accounts)
- Advanced – £3000 per month
- With the advanced tier, if you experience a DDoS attack, AWS will reimburse related charges Route 53, CloudFront, and ELB DDoS
