How to create an effective multi-cloud strategy
1. Classify data
The first thing to start is to identify all the clouds where the data is "residing" and ensure the organization has a powerful data management program - a complete picture of the data, the services, as well as the IT assets related to various types of information. Having such basic measures in place is becoming more important than ever, as data is gradually moving to the cloud and spread across many different cloud platforms.
Statistics show why having a strong security base is important. A 2018 report on the cloud threats from KPMG and Oracle, which surveyed over 450 IT and security experts, resulted that 90% of businesses classified half of their cloud-based data as sensitive. The report also found out 82% of respondents feared that their employees did not comply with cloud security policies, and 38% had problems detecting and responding to security incidents on the cloud.
To combat such situations, businesses should classify information to create multiple layers of security. This tells us that not all data requires the same level of trust and verification to access or lock.
2. Tighten security
Security experts also advise businesses to implement other common security measures on the foundation layers needed to protect the multi-cloud environment. In addition to the data classification policy, you can use encryption, identity and access management (IAM) solutions such as two-factor authentication (2FA), or standardization and automation…
Businesses need to standardize policies and structures to ensure consistent application and automation as much as possible, to help limit deviations from those security standards.
The level of effort a company poses will depend on the risks and sensitivity of the data. So, if you are using the cloud to store or handle non-confidential data, you don't need the security method as for a cloud holding important information.
Standardization and automation are also very effective. These measures not only reduce the total cost, but also allow security leaders to direct more resources for difficult tasks with higher value.
According to experts, such fundamental factors could be part of a larger and more coherent strategy. Businesses will do everything better if they apply a framework to manage security-related jobs.
3. Set expectations for cloud vendors
The chosen frameworks orient not only businesses but also cloud vendors. What we need to do is combine those frameworks with cloud service providers. You will then be able to build control measures around the data and services that you are trying to protect.
Security experts say negotiations with cloud vendors and subsequent service agreements will solve data isolation and how data is stored. They will cooperate and coordinate with other cloud providers, then provide services to businesses.
You need to understand the services you are getting from each provider and whether they are able to manage and run the service. At the same time, be specific about what you expect and how to get there.
However, do not entrust all the security issues to your cloud computing service providers. Cloud vendor often sell their services by emphasizing what they can do on behalf of business customers and often include security services. But that is not enough. Remember that these companies are in the cloud computing business, not in the security field.
Businesses' security leaders should build their own detailed security plans, such as who has access to what, when and how. Then give them to each cloud vendor for a better implementation of those plans.
