A Complete Guide on Hybrid Cloud Security for 2021

Introduction

Cloud computing can be defined as the use of various services like software development platforms, servers, storage, and software over the Internet, which is often referred to as ‘cloud.’ Instead of buying, owning, and maintaining physical data centres and servers, you can access technology services such as computing power, storage, and databases on a need-basis, from a cloud provider like Amazon Web Services.

Organizations of every type, size, and industry are using the cloud for a wide variety of uses like data backup, disaster recovery, software development, and testing, etc.

1. Types of clouds

Public clouds – They are made available to the general public or a large industry group. It further allows the organization to deliver highly scalable and reliable applications at a faster and affordable rate.

Private clouds – They reside within the boundaries of an organization and are used for the organization’s benefits, like enables an enterprise to manage the infrastructure and have more control.

Community clouds – In this cloud, computing infrastructure is shared between organizations of the same community.

Hybrid clouds – It is a composition of two or more clouds (public, private, or community). They have to maintain their unique identity but are bound together by standardized data and application portability.

2. What is Hybrid Cloud security?

It is maintained by both internal and external providers. IT professionals in complex enterprise organizations prefer hybrid cloud as it provides support and flexibility in sharing data and reducing workload for thousands of employees or multiple software development teams.

3. Hybrid Cloud security issues and challenges

Some of the security issues faced by this model are:

Compliance issues – In this model, the data traverses between high secured private cloud and less secured private cloud networks, which often causes threats to data and compliance standards.

Data Privacy – This model demands flexibility in data movement between public and private clouds, which means that there is a high chance of data falling prey to intruder attacks. 

Service level agreements –  Here, data governance and accountability are handed over to a public cloud service provider, which further can be a serious issue in cases of any security compromise leading to critical data loss.

Many challenges are also faced by hybrid cloud security as system administrators are faced with the need to choose third-party vendor software to arrange the network from the existing solutions available in the global marketplace. Also, a basic understanding of the goals and outcomes of the organization is needed as to how proper scaling of data shall be done, so that cloud capacity is maintained while maintaining security. 

4. Hybrid Cloud security best practices

Apply the principle of least privilege – This allows only selected users to have access to resources and data, which helps prevent users from accessing privileged data and can limit the damage caused.

Continuous audit of systems – Audit can help you uncover any changes or misconfiguration and correct any issues.

 Create backup and disaster recovery strategies – This will protect your source data or data loss from any attack. 

5. Hybrid Cloud architecture

Each of the environments that make up the hybrid cloud architecture has its own benefits and uses. The organization gains greater control over data safety, accessibility, privacy, authenticity for both your IT infrastructure and for your customer’s data, applications, and systems.

6. Components of Hybrid Cloud security

Mesh is an important feature in all layers of service of this cloud. At the webserver partition layer, the company primarily deploys hybrid cloud architecture using either hypervisor virtualization or container virtualization.

7. Technical Controls of Hybrid Control Security

The centralized management of hybrid cloud security makes technical controls easier to implement. Such controls include encryption, automation, orchestration, access control, and endpoint security.

Conclusion

Hybrid Clouds are a complex environment that requires special care during every step – from configuration to monitoring and data protection. It does not mean that you should avoid hybrid environments because by adopting best practices, you can properly configure and secure your hybrid cloud.
