Cyber Security Breaking Down Cloud Security

Breaking Down Cloud Security

Cloud security can be analysed by each segments.

Overview of Cloud Computing:

We are going to see below

• Security Implication
• Five Essential Characteristics Of Cloud
• Four Deployment Models
• Cloud service Models
• NIST Guidelines On Cloud Security

Security Implications:

• Data confidentiality and privacy are important for cloud network.
• Classification and marking data based on Cloud.
• Cloud network guarantees available resources.

Five Essential Characteristics Of Cloud:

• On demand self service
• Broad network access
• Resource pooling
• Rapid elasticity
• Measured services

Four Deployment models:

Public Cloud Network:

Public cloud network is used by general public over the Internet system exists with cloud providers

Private Cloud Network:

Private cloud used by single organisation systems and infrastructure will be on premises or with third party control.

Hybrid Cloud Network:

Hybrid cloud network services uses two or more distinct cloud infrastructure by the combination of public and private cloud.

Community Cloud:

Community cloud is a collection of organisations that share an affiliation operated by organisations or third party.

Cloud Services Model:

IAAS:Infrastructure as a service 

IAAS is a service provider will give infrastructure as a service.
Servers/Network/Storage devices.

PAAS:Platform as a service

PAAS is a service provider will give platform as a service. Support O/S - middleware/dev tools/hypervisors.

SAAS:Software as a service 

SAAS is a service provide will give software as a service. Salesforce.com/VDI/VX11/Google Docs/Drive/HCS.

NIST: National Institute Of Standards And Technology:

• NIST is a cloud computing Public security work group, which will used standard for security.
• NIST SP 500-292,NIST SP 500-293, NIST SP 500-299 for vol 1,2,3.NIST cloud computing reference architecture.
• NIST SP 800-144,NIST SP 800-145,NIST SP 800-146  are the guidelines for security in cloud environments.
