4. AWS Security by Design Approach
Identify
Requirements
Build a “Secure
Environment”
Enforce Use
of Templates
Perform Validation
Activities
PHASE 1 PHASE 2 PHASE 3 PHASE 4

5. Phase 1: Identify Requirements
• Document requirements
• Map AWS’ and your controls
• Decide what security rules you
want to enforce in the
environment
• Get GRC/security team involved
at the beginning
• Plan how you will perform
security-related operational tasks

7. Phase 2: Build a “Secure Environment”
• Reference Architectures
o Understand pattern/anti-patterns &
security templates
• Things to keep in mind:
o Access Management
o Network Segmentation
o Resource Constraints & Monitoring
o Encryption
• Enforce requirements with
automation
• Take advantage of security built
into AWS services

8. Phase 2: AWS CloudFormation Fundamentals
• Build network foundation
• Configure gateways and access points
• Install management services, like Puppet
• Allocate Amazon S3 buckets
• Attach encrypted volumes
• Control and manage access though IAM
• Register DNS names with Amazon
Route 53
• Configure log shipping and retention

11. Phase 2: Configuration Management
The goal of configuration management is to
create and maintain system configurations.
• “One-Two Punch” to configure environment
• Every instance gets configured in same way
• Encourages the adoption of evolving security standards
• Ability to enforce state
• New tools from AWS SSM

12. Phase 2: Build Process
Every instance follows the same process.
No “snowflake” systems.

13. Phase 3: Enforce the Use of Templates
• Enable agility but decrease risk
• Use AWS Service Catalog
• Appropriate access controls to
make sure only approved IT assets
are launched

14. Phase 3: AWS Service Catalog

15. Phase 4: Perform Validation Activities
• Enable the right monitoring
o AWS CloudTrail
o AWS Config
• Analyze your security data
at scale
• Automation enabled audit
evidence

16. 3 Key Takeaways
1) Better planning, no ad hoc environments that lead to an
unknown risk profile.
2) Get from heavyweight manpower & repeated tasks to software
orchestrating security.
3) Overwhelmed? Start with configuration management.
Throw people and money
at security.
• More hardware
• More engineers
• More complex processes
Develop software to
orchestrate security.
• Automated controls
• Repeatable templates
• Less manual work
