3 PREAMBLE SECURITY IS NOT A BARRIER, RATHER AN ENABLER ROOT CAUSE OF SECURITY BREACHES: People: Phishing, key usage Services: Web applications Configuration: Platform, systems ACADEMIC PRAGMATIC 4

4 Platform Risks

5 VENDOR MANAGEMENT Inherited compliance and certifications o Scope matters Indemnification and Liability Limits o Differ amongst hyper-scalers Privacy (NDA, privacy policies) Data storage & data sovereignty (DPA, Privacy Shield) Compliance Restrictions o Dedicated tenancy hosts 6

6 CUSTOMERS SHARED RESPONSIBILITY MODEL CUSTOMER CONTENT Platform, Applications, Identity & Access Management Operating System, Network & Firewall Configuration Customers are responsible for their security and compliance IN the Cloud Client-side Data Encryption Server-side Data Encryption Network Traffic Protection FOUNDATION SERVICES Compute Storage Database Networking GLOBAL INFRASTRUCTURE Availability Zones Regions Edge Locations AWS is responsible for the security OF the Cloud 7

7 PLATFORM SECURITY SETTINGS Numerous user controllable options governing cloud security. Define a corporate policy around appropriate settings, and ideally leverage tools which automatically check and report on a continual basis. USER SECURITY SETTINGS Root account Root API Password Policy MFA VPC Encryption Insecure SGs / NACLs IAM Policies Object Storage Permissions 8

8 IDENTITY AND FEDERATION External identity management provides: Unified identity for cloud and on premise users Integration into existing starters/leavers process Integration into corporate RBAC process (map to Roles) Sign-Sign On (MFA, UBA, etc..) 9

9 PaaS & SaaS

10 WISHFUL THINKING In a perfect world there would be a SaaS for every business function you need, customized precisely how you need it, that you trusted and complied with all regulations. Life would be easy. 11

11 AS-A-SERVICE DIFFERENTIATION SAAS Presentation Modality Data Integration & middleware APIs Core connectivity & delivery Abstraction RFP / CONTRACT IT IN Meta data Hardware Facilities Content PAAS Integration & middleware APIs Core connectivity & delivery Abstraction Hardware Facilities The lower down the stack the Cloud provider stops, the more security the consumer is tactically responsible for implementing & managing. IAAS APIs Core connectivity & delivery Abstraction Hardware Facilities BUILD IT IN 12

12 PLATFORM-AS-A-SERVICE SAAS + PLATFORM + DEVELOPERS Training Contract Platform specific security settings SSDLC Security Training Documented Security Requirements Integrated Security in Cloud Architecture Design CI/CD push from Dev to Prod Automated & Manual Testing Test SSDLC Secure Software Development Life Cycle Define SAST / DAST Code review with emphasis on critical components Develop Design 13

13 Instance Security (IaaS)

14 CHANGE INFRASTRUCTURE MATURITY STEADY STATE DATACENTER HIGH-VELOCITY CLOUD DEPLOYMENTS Generally labeled as Mode 1 Slowly changing applications with larger sets of changes per deployment Less time-critical, business-focused need to change Often seen in back-office applications Generally labeled as Mode 2 Also labeled as DevOps in popular press Key feature is smaller, more rapid deployments driven by need to provide direct business value Often necessary due to competitive landscape in a line of business + - MODE 1 MODE 2 Systems of Innovation Systems of Differentiation Systems of Record - + GOVERNANCE 15

15 MODE 1: SECURITY Manual Deployments Manual Patch Management & App Updates Governed Under Change Control 1 System Hardening Agent Based Security Virtual Network Appliances 16

16 MODE 2: SECURITY Immutable workloads AMI builds / image factory / container registry User-data bootstrapping 2 Auto-inheritence of security policies Auto-discovery via API and network No network chokepoints Identifiers should not be IP address based 17

17 Best Practices

18 ACCESS CONTROL API KEY MANAGEMENT Source code Servers Temporary Keys USER BASED Active Directory SSH Keys

19 GOVERNANCE Tagging Account & VPC segregation Continuous Integration / Continuous Deployment Cloud Access Security Broker (CASB) SaaS encryption, User Behavior Analytics / Compromised Credentials, Data Leak Protection 20

20 ARCHITECTURAL PATTERNS Management VPC Bastion Hosts NACLs & Security Groups VPN 21

21 NATIVE OR BRING YOUR OWN Key / Encryption Management Platform / Customer Managed Keys IAM Integration vs. Separate Identities HSM Network Management Scale or visibility? Centralized vs. distributed control
