Key AWS Services You Must Master
To pass the exam, you must deeply understand these services:
IAM (Identity and Access Management)
IAM is the backbone of AWS security. You should understand:
- Users, groups, roles, policies
- Trust relationships
- Cross-account access
- Temporary credentials
AWS KMS
KMS is used for encryption key management.
You should know:
- Key policies vs IAM policies
- Customer-managed keys (CMK)
- Automatic key rotation
- Integration with S3, RDS, EBS
AWS CloudTrail
CloudTrail records API activity.
Important topics:
- Management events vs data events
- Organization trails
- Log file integrity validation
- Multi-region logging
Amazon GuardDuty
GuardDuty is a threat detection service.
It analyzes:
- VPC Flow Logs
- DNS logs
- CloudTrail events
It helps detect:
- Unauthorized access attempts
- Credential compromise
- Malware activity
AWS Security Hub
Security Hub aggregates findings from multiple services.
It helps:
- Centralize security alerts
- Automate compliance checks
- Track security posture
Hands-On Skills You Should Practice
Reading alone is not enough. You need practical experience.
1. IAM Policy Creation
Practice writing:
- Inline policies
- Managed policies
- Role-based policies
2. KMS Encryption Setup
Try:
- Encrypting S3 buckets
- Using KMS keys for RDS
- Managing key rotation
3. CloudTrail Setup
Configure:
- Organization-wide logging
- Log storage in S3
- CloudWatch integration
4. GuardDuty Activation
Enable GuardDuty and simulate:
- Suspicious login activity
- Unauthorized API calls
5. Multi-Account Security Setup
