Definitions – Cloud ComputingCloud Computing is:

A model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications & services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

This cloud model promotes availability and is composed of:

5 essential characteristics 3 service models 4 deployment models

Cloud Definitions Cont’dCloud Characteristics

1. On-demand Self-Service – User provisions their services

2. Ubiquitous Network Access – Standard network or mobile access

3. Resource Pooling – Shared resources and location independence

4. Elasticity – Capabilities scaled or released “rapidly”

5. Measured Service – Metered, monitored and billed as utility

5

Cloud Definitions Cont’dCloud Service Models

1. Software as a Service (SaaS) – User access to the application

layer

2. Platform as a Service – User deployment using providers’ tools

3. Infrastructure as a Service (IaaS)– User access to IT

infrastructure

6

Cloud Definitions Cont’dCloud Deployment Models

1. Private Cloud – Deployed for a single organization or company

2. Community Cloud – Shared by organizations with similar needs

3. Public Cloud – Cloud services available to all and shared

4. Hybrid Cloud – Two or more clouds with operational relationship

Approach to Security in the CloudGovernance

• Assessing the Risk

• Managing and Measuring Posture and Response

Compliance

• Direct policy and technology requirements to meet regulations

Architecture

• The technical components and their inherent strength and weaknesses

Resiliency

• The ability to withstand and/or recover from an incident

Process

• Established, regular, IT practices that ensure policy adherence

Access

• Identity and authentication

Identity and Access Management

• Authentication tie-ins to customer, stand alone

Data Protection

• Backups and Recovery

• Data Location and Encryption

• Physical Security

A Few Words On EncryptionEncryption Built into Cloud Service vs Encrypting at the Source

• SaaS and PaaS:

• SSL based transfer prior to encryption in the cloud

• Read and Understand the Privacy Policy

• Cloud Storage

• Encrypt locally, then store in the cloud (e.g. DropBox)

o Viivo, Sookasa, BoxCryptor, CloudFogger

• Use an integrated hybrid cloud storage solution

o Wualu, SpiderOak, Tresorit

• Use Appliance Based Backups & BC

o Walker/Datto

13

Encryption (cont’d)

Cloud Storage features to Look for:

• Granularity: File vs Container vs Volume

• Key Management

• Administrative Features to meet your needs (e.g. compliance)

• Does it work with the service(s) you use?

• Dropbox, Box.com, Google Drive, Microsoft SkyDrive, Amazon S3
