Section 15.133 Security Architecture: On Premise vs The Cloud Flashcards
Objective 3.1 Compare and contrast security implications of different architecture models. Objectives 4.1 Given a scenario, apply common security techniques to computing resources
Security Architecture
Design, structure, and behavior of an organisations information security environment
On-premise versus the Cloud
Cloud Computing
Delivery of computing services over the internet, including servers, storage, databases, networking, software, analytics, and intelligence
Cloud Computing Advantages
● Faster innovation
● Flexible resources
● Economies of scale
Responsibility Matrix
Outlines the division of responsibilities between the cloud service provider and the customer
Example: A service Model Business
Cloud service provider = Manages the infrastructure
Customer (Netflix) = Handles everyting esle like Operating system, Middleware, Runtime, Data and Application
Third-Party Vendors
Provides specialised services to enhance functionality, security, and efficiency of cloud solutions
Hybrid Solutions
Combined on-premise, private cloud, and public cloud services, allowing
workload flexibility
Considerations:
● Sensitive data is protected
● Regulatory requirements are met
● Systems can communicate with each other
● The solution is cost-effectiveness
On-Premise Solutions
Computing infrastructure physically located on-site at a business
Key Considerations in Cloud Computing
1 Availability
System’s ability to be accessed when needed
Key Considerations in Cloud Computing
2 Resilience
System’s ability to recover from failures
Key Considerations in Cloud Computing
3 Cost
Consider both upfront and long-term costs
Key Considerations in Cloud Computing
4 Responsiveness
Speed at which the system can adapt to demand
Key Considerations in Cloud Computing
5 Scalability
System’s ability to handle increased workloads
Key Considerations in Cloud Computing
6 Ease of Deployment
Cloud services are easier to set up than on-premise solutions
Key Considerations in Cloud Computing
7 Risk Transference
Some risks are transferred to the provider, but customers are responsible for security
Key Considerations in Cloud Computing
8 Ease of Recovery
Cloud services offer easy data recovery and backup solutions
