Region
An independent collection of AWS
resources in a defined geography
A solid foundation for meeting location-
dependent privacy and compliance
requirements

Availability Zone
Designed as independent failure zones
Physically separated within a typical
metropolitan region

7. AWS Global Footprint

8. AWS Global Footprint
Edge Location
collections of servers in geographically
dispersed data centers
deliver content to end users with lower latency

9. AWS Global Footprint

10. AWS Global Footprint
12 Regions
33 Availability Zones
54 Edge locations
Over 1 million active customers
Every day, AWS adds enough new server
capacity to support Amazon.com when it was a
$7 billion global enterprise.

11. Data Locality
Customer chooses where to place data
AWS regions are geographically isolated by
design
Data is not replicated to other AWS regions
and doesn’t move unless you choose to move it

12. Data Locality in practice
Block level storage
Instance Storage (Elastic Cloud Compute - EC2)
Elastic Block Storage (EBS)
Object level storage
Simple Storage Service (S3)
Database storage
Relational Database Service (RDS)
NoSQL (DynamoDB)
Columnar (Redshift)
Caching (Elasticache)

13. Shared Responsibility
Who manages which parts?

14. AWS Foundation Services
Compute Storage Database Networking
AWS Global
Infrastructure Regions
Availability Zones
Edge Locations
Client-side Data
Encryption
Server-side Data
Encryption
Network Traffic
Protection
Platform, Applications, Identity & Access Management
Operating System, Network & Firewall Configuration
Customer content
Customers
AWS Shared Responsibility Model
Customers are
responsible for
their security and
compliance IN
the Cloud
AWS is
responsible for
the security OF
the Cloud

15. Interacting with AWS (common protocols)
Management
SSH
RDP
Database
MySQL
MS SQL
Oracle
File Transfer
FTP, etc…..

16. Interacting with AWS
Application Program Interface (API)
API Endpoints per Service
API Endpoints per Region
Service Interaction
AWS Management Console
AWS SDKs (Java, Python, PHP, .NET, Ruby,
Go)
AWS Unified CLI
Service Interaction Examples:
aws ec2 describe-instances
aws ec2 start-instances –instance-ids <value>
aws ec2 stop-instances –instance-ids <value>
aws s3 ls
aws s3 mb s3://mybucket --region eu-west-1
aws s3 cp object.file s3://mybucket/object.file
aws s3 sync s3://mybucket ./localfolder/

25. Shared Responsibility
What about security OF the cloud?

26. Security Shared Responsibility Model
AWS is responsible
for the security OF
the cloud

27. Auditing - Comparison
on-prem vs on AWS
Start with bare concrete
Functionally optional – you can build a secure
system without it
Audits done by an in-house team
Accountable to yourself
Typically check once a year
Workload-specific compliance checks
Must keep pace and invest in security innovation
on-prem
Start on base of accredited services
Functionally necessary – high watermark of
requirements
Audits done by third party experts
Accountable to everyone
Continuous monitoring
Compliance approach based on all workload
scenarios
Security innovation drives broad compliance
on AWS

28. What this means
You benefit from an environment built for the most security
sensitive organizations
AWS manages 1,800+ security controls so you don’t have to
You get to define the right security controls for your workload
sensitivity
You always have full ownership and control of your data

29. AWS Assurance Programs

30. AWS Foundation Services

Meet your own security objectives
Customer scope and
effort is reduced
Better results through
focused efforts
Built on AWS
consistent baseline
controls
Your own
external audits
Customers
Your own
accreditation
Your own
certifications

31. Navigating Shared Responsibility
Achieving accreditation or certification on
AWS is possible but how can we help?

32. Industry Best Practices for
Securing AWS Resources
CIS Amazon Web Services Foundations
Architecture agnostic set of security configuration
best practices
