I recently passed the AWS Certified Security — Specialty Exam. I’d like to share my thoughts on what I did to pass and some notes I kept along the way. Before beginning, it’s worth considering what this exam is about.
AWS Certified Security – Specialty is intended for individuals who perform a security role and have at least two years of hands-on experience securing AWS workloads.
Earning AWS Certified Security – Specialty validates expertise in securing data and workloads in the AWS Cloud. This exam helps organizations identify and develop talent with critical skills for implementing cloud initiatives.
This article gives you an overview which content and training material I used to prepare myself for the AWS SCS-C01 exam.
Before you take this exam, AWS recommends you have:
- Five years of IT security experience in designing and implementing security solutions and at least two years of hands-on experience in securing AWS workloads
- Working knowledge of AWS security services and features of services to provide a secure production environment and an understanding of security operations and risks
- Knowledge of the AWS shared responsibility model and its application; security controls for workloads on AWS; logging and monitoring strategies; cloud security threat models; patch management and security automation; ways to enhance AWS security services with third-party tools and services; and disaster recovery controls, including BCP and backups, encryption, access control, and data retention
- Understanding of specialized data classifications and AWS data protection mechanisms, data-encryption methods and AWS mechanisms to implement them, and secure internet protocols and AWS mechanisms to implement them
- Ability to make tradeoff decisions with regard to cost, security, and deployment complexity to meet a set of application requirements

How did I prepare ?
I spend a considerable amount of time learning AWS before attempting to take the Certification Exam. It is important that you spend time with AWS for you to be good at it. The Resources I used while preparing I am linking them below one by one.
1) 📚 Courses I took: Initially, I enrolled in a course on Udemy called “AWS Certified Security Specialty” by Zeal Vora which is a very good course and covers all the most important aspects of the AWS and You will be able to Master the Security aspect of AWS.
👉 More Information on the udemy course can be found here
2)🛠️ hands-on projects: Learning only theory won’t help , you must work on some hands-on AWS projects. I would recommend you to practice some of the AWS projects from here or you can practice them from skills builder learning Center.
👉some of the projects I practiced are mentioned in my github repository. I have some AWS security related projects as well.
3)📋 AWS Ramp-Up Guides: Your guides to learning the AWS Cloud.
- AWS Ramp-Up Guides offer a variety of resources to help you build your skills and knowledge of the AWS Cloud. Each guide features carefully selected digital training, classroom courses, videos, whitepapers, certifications, and more. Explore the guides below by role, solution, or industry area.
👉 more details can be found here
👉 Focus more on Security Solution
4) 🤝 being part of a Study Groups: I also recommend you to be part of a study groups. it helps you stay focused, probably having study groups with people studying for the same exam is an added benefit.
Study Groups I was part of:
Cloud and DevOps Babies are a global group of babies with curious minds to learn/decode Cloud, DevOps and Microservices tech stacks.
👉 more details can be found here
- Tech Study Slack:
TechStudySlack is a Slack for people studying Tech

5)✍️ practice tests: Lastly I recommend all of you to pass these practice exams before attending the real exam. It provides simulated questions that are very similar to the actual exam.
One of the selling points of this practice exam is that each question contains detailed explanations that will help you gain a deeper understanding of AWS services. It not just explains what the correct answer is, but also explains why other answers are wrong. It is extremely helpful to make you recognize the difference between similar services.

6)📝 Notes: I outlined the resources I would use and a rough guideline of how I would approach studying. You should find something that works for you but have structure and commit to it.
Useful Study tips and tricks
As usual, more study tips and tricks to help you with the exam:
- This exam is available through online proctoring so that you don’t have to travel to the nearby testing center to take this exam.
- Additional handicap of 30 minutes for non-native English speakers is still available, so make sure that you have requested that.
- Make sure you will use the flagging mechanism and reiterate the questions if you have time.
- There is no penalty for guessing.
- You can and should apply the same rules as in the other exams look here for more details regarding how to read a question and answers.
I hope this will help you to prepare and evaluate your knowledge.
