For organizations in all sectors, migration to the public cloud from the private cloud has been quick and inexorable. Cost savings, ease of use, and efficiency have made cloud adoption a no-brainer for today’s businesses, which have decreased errors, been more flexible, and improved customer experiences over time by shifting their data to public cloud platforms.
Organizations have revamped their IT strategies in recent years, transferring a large percentage of their apps and data to public-cloud infrastructure and platforms. Migrating from a private to a public cloud, on the other hand, goes against established cybersecurity models that businesses have been following for years. Businesses should upscale their cybersecurity strategy to use cloud services securely while fully using the speed and agility that these services offer, given the growing thirst for public cloud.
Concerns about security when migrating from a private to a public cloud
Many organizations find it difficult to effectively manage the security and compliance of public cloud deployments. This could be due to a lack of standard language for distinct public cloud components.
Aside from terminology, a number of factors have a role in the challenges of deploying and sustaining highly secure public cloud infrastructures. Before moving to the public cloud, there are a few security issues to keep in mind.
Adhere to the model of shared responsibility
A shared security responsibility regime is followed by cloud service providers. The security team retains some security responsibilities when firms move apps, data, and workloads to the cloud. The provider, on the other hand, assumes some but not all of them. To decrease the potential of introducing problems into the public cloud, it’s necessary to clarify the boundary between provider and user responsibilities.
While a Software as a Service (SaaS) deployment reduces the number of elements for which a public cloud user is responsible, responsibilities increase when employing a Platform as a Service (PaaS) deployment and continue to grow with Infrastructure as a Service (IaaS) deployments.
After enterprises understand the aspects they are responsible for protecting and have completely updated visibility into their cloud resources and linked assets, the next crucial duty is to build, maintain, and implement authorized configurations. In such contexts, in addition to existing industry standards, privately established compliance and security measures should be included. After such allowed configurations are produced and deployed, it’s critical that the assets and related resources deployed inside public clouds are regularly examined and their permitted configurations maintained.
Cloud settings do not have the security silos that exist in on-premises data centers, which is a major benefit. It allows security teams to assess risk across identities, data, networks, and workloads, allowing them to quickly understand and reduce the attack surface.
Examine the apps and how they are affecting workflow
Before embarking on a cloud migration project, organizations should conduct an audit of their applications and evaluate workload behaviors to ensure that the cloud deployment does not inherit any undesirable or privileged access permissions. Furthermore, applications and workloads that are migrated to the cloud should be hardened according to NIST standards and regularly reviewed for compliance with these best practice guidelines, including settings and file integrity controls. All application activity should be monitored after migration to ensure that apps and workloads continue to behave as expected. In the meantime, new application requirements or changes should be recorded and updated for cloud monitoring.
