Through Automation

Compliance & Accreditation
 How do I architect for compliance in AWS?
 How can I make architecting for compliance repeatable?
 How can I validate that my architecture is compliant before
deployment?
 How can I ensure continuous compliance in production?
 How can I simplify my accreditation process and get to ATO faster?

3.
Compliance Frameworks
 NIST SP 800-53
 DoD CSM Levels 1-2
 DIACAP/FISMA
 FedRAMP
 PCI DSS
 HIPAA
 MPAA
 CJIS

4.
Shared Responsibility Model
Customers are responsible for how they use AWS components in AWS
Customer Data
Platform, Applications,
Identity & Access Management
Operating System, Network &
Firewall Configuration

Customer Challenges
 Meeting compliance requirements (NIST, PCI, HIPAA, CJIS, etc.)
 Taking advantage of new services and features when designing for the
Cloud
 Making many critical decisions to ensure a secure application when
using the AWS Shared Responsibility Model
 Mapping security controls to numerous AWS services
− Example: 400 NIST 800-53 Security Controls to 42 AWS services
Common Challenges in Compliance

6.
Shared Responsibility Model
Compliance in the Cloud: Examples
Framework Control Description Implementation in AWS Architecture (Example)
NIST 800-53 AU-9 The information system protects
audit information and audit tools from
unauthorized access, modification,
and deletion
AWS CloudTrail and/or log files in S3 buckets which have
S3 bucket policies to prevent modification or deletion (write
once read many)
PCI DSS Requirement 4 Encrypt transmission of cardholder
data
Elastic load balancers must enforce HTTPS encryption
using strong security policies enforcing TLS
HIPAA - Tenancy requirement Requirement to use “dedicated” tenancy for EC2 instances
storing or processing PHI data
CJIS Policy Area 7 Configuration management Enforce use of hardened EC2 instance operating systems
and/or pre-approved Amazon Machine Images (AMIs)
DoD CSM Levels 4-5 No direct access from VPC to the
Internet
Amazon VPCs for Impact Levels 4-5 data require VPN
connection, no Internet gateway (IGW)

7.
Simplifying Compliance: Key Concepts
 Know your compliance framework(s)
− Translate compliance controls to technical implementation
− Create and manage a pre-approved common security controls mapping (SCTM,
CRM, etc.) to use when architecting for security and compliance
 Distinguish between inherited controls vs. customer controls
− Establish (in advance) which controls are inherited by the global infrastructure
 Take advantage of capabilities the Cloud provides
− Infrastructure as Code
− AWS services (CloudTrail, AWS Config, Amazon Inspector, etc.)
− Partner solutions
 Automate standard implementations

8.
Automation
 Why automate compliance?
− Reduced time to ATO
− Lower cost
− Fewer resources required
− Less human error
− Consistency
− Reproducible

9.
Automating Compliance in AWS
 Infrastructure As Code
− Managed and controlled like software
− Validate pre-deployment
− Test-driven development (TDD) for security and compliance
 Standardization
− Predefined guidelines, mapped to security controls
− Consistent, reusable architecture and configuration
 Compliance at scale
− Enforce policies across accounts, workloads, systems
− Shared services for security, logging, monitoring, access control
 Transparency
− Everything is an API call!
− Auditability, logging
− Continuous monitoring (CM) for both applications and infrastructure

Pre-Development
 Understand your compliance requirements
− Compliance type(s): NIST 800-53, ICD 503, DoD CSM,
PCI, HIPAA, etc.
− Workload-specific: DoD CSM Levels 1-2, FedRAMP High,
etc.
 Architect for compliance
− Map security controls to technical implementation
 Predefine baselines
− Examples: VPC configuration, connectivity, AWS Identity
and Access Management (IAM) configuration,
logging/monitoring
− Baselines align with governance model

Development
 Deploy predefined baseline environment
− Service Catalog
 Manage all AWS components as code
− Version Control (AWS CodeCommit, Git, SVN)
 Take advantage of AWS services
− AWS CodeDeploy/AWS CodePipeline
− Elastic Beanstalk
− OpsWorks
 Submit for IATT (prepare for ATO)
− Simplify the process of security controls

Testing
 Unit testing
− Validate before deployment
− Check AWS CloudFormation templates for
non-compliant configurations
 Integration testing
− Deploy infrastructure code into AWS account
− Run tests for validation (Config, Inspector,
HBSS, partner products, etc.)
 Prepare for ATO
− Submit predefined security controls mapping
for simplified ISSO/ISSM approval

Testing Infrastructure Code
 Identify resource configurations in
code that violate compliance
− Example tools:
https://github.com/stelligent/cfn_nag
 Common points of compliance
validation
− Security group rules
− Network Access Control List (network ACL)
rules
− IAM policies
− S3 bucket policies
− Elastic Load Balancing security policies
"sg": {
"Type":
"AWS::EC2::SecurityGroup",
"Properties": {
"SecurityGroupIngress": {
"CidrIp": “0.0.0.0/0",

}
}
}
Example: AWS CloudFormation template

unrestricted access to SSH

16.
Production
 Authority to Operate (ATO)
− …but compliance doesn’t end with ATO
 Continuous monitoring
− Security-relevant changes to configuration
 Non-compliance
− Continuously monitor for changes that violate
compliance
− Immediate notifications
− Event-driven, automated remediation

EXCEPTION: The information
system at managed interfaces
denies network communications
traffic by default and allows network
communications traffic by exception
(that is, deny all, permit by
exception).

control and takes
corrective action if a

Requirement: Rules with
“ALL TRAFFIC” not

If security group changes,
Config rule immediately
