Remediate compromised containers across ECS, Docker on EC2, and EKS by isolating tasks and updating images. Review Kubernetes config map, service accounts, and rotate access keys; redeploy with CI/CD.
Learn to set up a CloudWatch alarm for low disk space using the CloudWatch agent and System Manager automation to safely halt batch processing when space runs low.
Discover how CloudWatch Logs organize data into log groups and streams, view storage size, and access log data, highlighting the centralized logging approach used by AWS services and applications.
Explore dns resolver logs in Amazon Route 53, including resolver query logging and log destinations such as CloudWatch, s3, or kinesis, and how caching affects log records.
Block direct user access to the load balancer and permit only CloudFront by using a secret header in CloudFront origins and a routing rule with a default 403 response.
Learn to configure rate limiting in a web application firewall with a rate-based rule that caps requests at ten per minute by source ip or api key, with debugging logs.
Explore how to connect VPCs using a Transit Gateway, compare with VPC peering, and learn to attach VPCs, update route tables, and test cross-VPC connectivity at scale.
Learn to set up an Amazon Cognito user pool for web app authentication, obtaining access and id tokens, and retrieving temporary AWS credentials.
Block public access in S3 to prevent public bucket access, protecting data from breaches. For new accounts, enable account-wide block; if public objects are needed, use an alternative method.
Learn to enforce TLS for Amazon RDS MySQL by using a CA bundle, installing the MySQL client, and configuring parameter groups to require secure transport and verify identity.

Create an AWS organization with a management account, invite subaccounts, and implement IAM Identity Center for cross-account access and centralized account management.
Set up and govern an Atlas multi-account AWS environment with Control Tower, enforcing guardrails and CloudTrail across accounts. Configure landing zones, organizational units, account factory, and IAM Identity Center.
Service control policies act as guardrails that limit permissions across member accounts, deny tampering with control tower resources, and enforce regional and service-level restrictions.
Test the services and concepts yourself to prepare for the ALS exam, compare solutions to understand the business case, and consult the recommended documentation and blogs.
If you're looking to prepare for the AWS Certified Security Specialty exam, look no further! I took the exam earlier and passed it without any preparation. This is because of my years of security experience and working with AWS since 2015.
In this course, I want to share my knowledge about security and AWS to help you understand how to manage security in AWS. I don't use slides with bullet points but rather try to explain the why, not only the how. This should make it easier for you to retain the knowledge and, with some extra studying, pass the exam! The course contains many demos showing me how to use AWS security services, and how they work together.
In the last 8 years, I have been publishing courses to Udemy in Cloud & DevOps technologies I'm very familiar with, using them on a day-to-day basis. This course is no different. Have a look at the preview lectures to see if you like my teaching style. Enroll in my course, and you can contact me through the Q&A or direct message. Up to now, I have personally answered every single question asked to me on Udemy!
See you in the course!
