What is Hybrid Cloud Security?

Hybrid Cloud Security describes the unique process of applying cybersecurity tactics and methods to environments that are split across multiple types of cloud resources. Typically, hybrid cloud environments include are a private cloud, which a company generally operates and hosts on-premise, and a public cloud, for which a third party is engaged.

A hybrid cloud can allow for different types of data deployment and can make companies’ operations more flexible and dynamic, but this type of network is not without its challenges. This is where Hybrid Cloud Security comes in.


Jargon Buster

Before we get started, let’s break down some of the key terms related to Hybrid Cloud Security, so you can easily differentiate between them.

  • Private Cloud: An in-house or on-premises cloud on which a company or organization stores their data and systems.
  • Public Cloud: Third-party services such as Amazon Web Services or Microsoft Azure that allow users to purchase space on their servers.
  • Hybrid Cloud: Using multiple cloud solutions, typically a mix of private and public clouds, to store, manage, and retrieve data.
  • Hybrid Cloud Security: Tools, procedures, and capabilities that contribute to the security of a Hybrid Cloud network.
  • Hybrid Cloud Security Orchestration: Processes that enable multiple security tools to act together to secure a network.
  • Hybrid Cloud Security Automation: Actions by security tools that respond to threats with predetermined actions and workflows that require little-to-no human involvement.
  • Hybrid SOAR: A security orchestration, automation and response tool that supports Hybrid Cloud environments.
  • MultiCloud: A system using any combination of two or more types of cloud. Also known as Polycloud.
  • Cloud-Native: An approach to building applications, networks, and services specifically for a cloud-based environment.


Hybrid Cloud Challenges

In increasing the number of locations where data is stored, organizations are also increasing the number of access points to that data.

A multitude of cybersecurity products must act in concert to secure the network, and any weakness in any one of these, be they Endpoint, Firewall or SIEM, may provide the weak link a hacker needs to gain access. In many cases, distinct tool sets are needed for the private and public cloud instances, creating two security stacks that are not designed to share data and workflows between them.

As these security products multiply, so too do their analytics and the security alerts they produce. Over time, analysts may become fatigued to these alerts, and the potential for an incident to go unnoticed will increase.


Hybrid Cloud Advantages

If it can be made appropriately secure, a Hybrid Cloud network offers major benefits to business. With essential and confidential information kept secure on the Private Cloud, non-essential operations can be relocated to the Public Cloud, conserving resources and bandwidth. Organizations that see fluctuations or spikes in the use of their networks may benefit from a Hybrid System in this way. For example, Big Data companies utilizes Hybrid Cloud by running tasks on their private cloud and storing the datasets in the public cloud.

A Hybrid Cloud network, also gives a company more options for how to deploy its data and architecture, making them adaptable to shifting priorities.


D3 Security and Your Hybrid Cloud Security Strategy

To manage the security complications of Hybrid Clouds, a single pane of glass solution is optimal. D3’s SOAR platform is uniquely qualified to provide this, seamlessly acting as a hub between on-premise, private cloud, and public cloud environments.

For example, D3 can ingest alerts from both an on-premise SIEM and a public cloud SIEM, such as Microsoft Azure Sentinel, and orchestrate an automation-powered playbook that acts across cloud and on-premise security tools, such as endpoint protection, firewall, and email security. This keeps security teams focused on a unified queue of alerts, instead of bouncing between multiple interfaces and workflows.

D3 utilizes a codeless visual playbook editor to automate cybersecurity responses. This means there is no need for costly code development or scripting to integrate security tools, and response playbooks can be altered rapidly to suit changing conditions. Scaled up over a enterprise-scale Hybrid Cloud infrastructure, the savings from this quickly become immeasurable.

D3 has also embedded the MITRE ATT&CK matrix into its SOAR platform, so that security events can be automatically enriched with information drawn from MITRE’s vast database of adversary tactics, techniques, and procedures. D3 uses ATT&CK to find related events that are part of the same larger incident. This is especially valuable in a Hybrid Cloud security environment, because adversaries might move between clouds during an attack, making their movements harder to track using siloed security stacks.
