- B . lower total cost
- C . ideal for large projects
- D . reduced risk in the design process
A private cloud is accessed over the private IT network infrastructure that is potentially vulnerable to violations, data leaks, and man-in- the-middle attacks.
The security team is evaluating the following solutions to address the challenges:
• Encrypt data at rest and in transition.
• Use strong identity and access management (IAM) capabilities.
• Communicate the inherent data security risks to your customers and end-users.
Assuming that adoption of a hybrid cloud model is likely to occur within the next 12 months, which two solutions can also help provide protection in a hybrid cloud environment? (Choose two.)
- A . Avoid automating the scanning and remediation of security controls using open-source tooling
- B . Practice SSH network protocols for data communication between unsecured network connections
- C . Implement a common protective methodology for the same information at rest or motion at different points of time
- D . Provide distributed management and visibility across the infrastructure instead of centralized management
- E . Apply cryptographic protocols to secure data transmission over the network
