3. Cloud Security = Shared Responsibility
3
• Know Your Role and Responsibilities!
• Responsibility dependent on:
• Type of service
• Delivery model
• Service provider

5. Physical Security
5
• Not “our” problem!

6. Host Infrastructure
6
• Secure the virtual device like it’s
“within your walls”
• AV & threat protection
• Patching
• Application updates
• Host encryption

7. Network Controls
7
• What can we expect from CSP?
• Provide the infrastructure
• Protect their infrastructure
• Basic built-in tools for customer

8. Network Controls
8
• CSP Provides
• Virtual Networking
• Load Balancing
• DNS
• Gateway
• VPN
• Network Security Groups (group of ACLs)
• Basic NAT or PAT
• Basic port open port closed
• Logical Network Segmentation

9. Network Controls
9
• Customer Responsibility
• Next Generation Firewall (NGFW)
• Web Application Firewall (WAF)
• Route all traffic through NGFW
• Access Management
• Consider 2FA
• Interrogate/Inspect traffic
• AV/Malware/IPS/DLP
• Log and monitor traffic
• Encrypt traffic

10. Application Level Controls
10
• Infrastructure as a Service (IaaS)
• We install the applications, we must
security them!
• Platform as a Service (PaaS)
• SQL
• Web Services
• PaaS protection through
• Application level “firewall” settings
• Identity management
• SAML
• Azure Active Directory
“Because you’re building systems on top of the AWS
cloud infrastructure, the security responsibilities will
be shared: AWS manages the underlying
infrastructure, and you secure anything you put on
the infrastructure or connect to the infrastructure.”
- Amazon Web Services
“Sharing the Security Services”

11. Identity & Access Management
11
• Access and authorization
• Identity protection
• Service management through user access
• Tools
• Multi Factor Authentication
• Same sign on / Single sign on
• Identity providers / SAML
• Roles
• Auditing and alerting
• Conditional access

12. Single Sign On and Identity Management
12
• More password = less secure passwords
• Identity providers – OKTA, Duo,
Microsoft, OneLogin
• Regardless of Identity Solution
• Every business needs to be setup in
Microsoft Azure Active Directory
• Most businesses should be federated
with Azure Active Directory
• Enables
• Windows Store for Business
• Identity management
• Keeps users away from consumer
accounts!

13. Client & End-point Protection
13
• End-points are always our responsibility
• How end point connects determines risk
• PaaS is probably connected to my network
• IaaS same risks as on-prem
• SaaS more likely app or browser based
devices won’t directly access systems
• Device has access to data flowing through it!
• Advanced threat protection
• Microsoft Defender and Intune
• Cylance
• Carbon Black

14. Data Classification & Accountability
14
• Compliance obligations
• Distinguish - and potentially secure - sensitive
data
• SaaS - capabilities aren’t meaningful without
classification – Digital Loss Prevention
• PaaS & IaaS – Data management fully your
responsibility
• Backups
• Encryption
