AWS Certified Security – Specialty Exam Study Path
The AWS Specialty certification exams are intended for people who handle more specific responsibilities in AWS Cloud. Since these responsibilities demand a more advanced skill set with prior experience from a person, these AWS specialty exams are built so that they could reinforce and validate a person’s eligibility for that role. There are no associate and professional levels in a specialty learning path, so the exams serve as the whole package already. And since they are made that way, expect no less from the specialty certification exams, as they will be as tough as the professional exams.
The name of the certificate immediately points out what to focus on — AWS Security. Although we mentioned earlier that specialty exams tackle more specific roles, security in AWS is very broad and extensive. There are a lot of topics involved when we speak about AWS security, whether it be native AWS services or other third-party tools. If you need a comprehensive review material for learning these topics then this study guide is for you.
Having prior knowledge and experience in handling (cloud) security will allow you to understand the concepts and strategies that appear in AWS reference materials. You will also find it easier to comprehend scenario type questions in your exam. To know more about the AWS Security specialty exam, check out the official AWS Exam Blueprint here.
