Overcoming Hybrid Cloud Security Issues Using Tactics

Companies adoption of hybrid cloud spiked during the work from home period

Hybrid cloud computing allows organizations to take advantage of both public and private cloud models. A hybrid environment brings with it the promises of choice and flexibility, allowing IT leaders to keep data in whichever environment that works best for that data from both a compute and security perspective. However, one of the primary concerns that prevent cloud migration is the security of data in the cloud.

Since the Covid-19 pandemic broke out, and employees started working remotely, companies adopted the hybrid cloud system to share and store important information. Hybrid cloud slowly became a part of an everyday working system for many organizations. As the usage increased, more people juggled business with personal engagements at times. With employees working outside business hours, they began using the mobile business laptop, as well as a plethora of additional wireless mobile devices. This has increased the security demands on the hybrid cloud.

Here are some of the hints business could consider in order to increase the security of a hybrid cloud environment.


Careful analysis of complex hybrid cloud 

Cloud environments are a composite of legacy applications hosted in the data centre and newer applications hosted on the public cloud. This produces a mix of multiple authentication systems and various forms of access control. The procedure might require federated security or legacy integrations through anti-corruption design patterns. The hybrid cloud security model requires careful analysis of all components residing on platforms with different characteristics in such situations. For example, if a mainframe application program is hosted in a data centre, it is extended to support mobile devices access through service running on the public cloud. The strict security control with the original program could potentially be bypassed or defeated as the mainframe program is extended into supporting cloud-hosted services.

The mishap could be prevented by conducting careful analysis and testing to ensure new security vulnerabilities, which are not introduced during the process of application modernization.


Mapping the methodical flow of data

Data is basically categorized into security levels ranging from ‘highly sensitive’ to ‘public.’ Various policies are created for accessing and updating the data in the data security classification policy. This leverages the extend of data that could be accessed by anyone according to their position. However, hybrid cloud data resides on multiple platforms. Often, the same data is distributed to various levels and might not be fully aligned with the security characteristics of the original data. For example, an intranet search crawler can index data with restricted access along with public data. A security breach could result if the restricted data index contents are returned during a search by an unauthorized user.

The only way out from this is to use methodical data flow mapping to ensure data security constraints when the hybrid cloud is handling sensitive data.


Comprehending endpoint security strategy for mobile access

The usage of mobile devices to deal with hybrid cloud has increased during the work from the home period. Earlier, accessing intranet applications from the corporate network on the secure office premise was followed as a routine. However, it is slowly vanishing due to the Covid-19 situation. This spikes the vulnerability footprint due to interactions with mobile devices of varying capabilities that might be in potentially insecure locations.

A comprehensive endpoint security strategy is necessary to address the issue. The strategy should have other security controls such as limiting certain operations from mobile devices. To add more encryption, companies can include fingerprint access to perform certain operations and a robust security monitoring capability to detect unauthorized usage quickly.
