Hybrid cloud security management:
Best practices + solution

Hybrid cloud security describes the coordinated implementation of tools, processes, and technical know-how that an organization uses to protect its infrastructures, applications, and data across multi-cloud environments (public, private) and on-premises network devices.

The building blocks of hybrid cloud security highlight how demanding it is to safeguard these interconnected resources–and the data that travels between them. From policy design to harmonizing security controls, managing cloud providers, and automating workflows to keep up with business needs, the process can stretch security and IT teams to their limits.

What Is hybrid cloud security?

Many businesses struggle to manage an incompatible and time-consuming patchwork of tools to protect their hybrid environment. Because conventional security solutions work for either on-premise or public cloud assets, this creates security gaps and expands their attack surface.


Private cloud security


A private cloud platform can be a smart investment for some organizations, especially those in highly regulated sectors. It offers unparalleled protection for sensitive data, customizable cybersecurity, and powerful access control.

However, a private cloud setup compels organizations to take full responsibility for physical and network security, encryption, and data storage techniques, while also ensuring scalability and flexibility. Given the magnitude of this challenge, enterprises often choose a hybrid cloud architecture.


Public cloud security


Public cloud systems, such as SaaS (software-as-a-service), IaaS (infrastructure-as-a-service), or PaaS (platform-as-a-service), offer limited visibility into the provider’s security tools and processes.

Despite their heavy investment in security, the biggest public cloud service providers (Amazon AWS, Google Cloud, Microsoft Azure, Cisco, VMware) can’t fully protect against all threats. This makes the shared responsibility for cloud security model crucial.

What are the 2 other categories of cloud security?

A well-managed hybrid cloud architecture offers great security benefits despite its increased complexity.


Greater control over data security


Hybrid cloud flexibility grants businesses greater security control. They can store highly confidential data in on-premise data centers for greater protection and use the public cloud to handle less sensitive data.

Hybrid cloud architecture also allows plug-and-play security solutions to extend visibility and management across the entire estate using automation.


Access to cutting-edge security technologies


Reputable cloud service providers hire top talent and use advanced tools to remain essential to their clients. Internal teams can elevate their skills and knowledge by tapping into the resources they offer.

Companies can also layer cutting-edge tech onto hybrid cloud security setups to become vendor-neutral and preserve the security posture as their IT infrastructure evolves.


Stronger business continuity and disaster recovery


The hybrid cloud model helps DevSecOps improve operational availability. Backup options at multiple sites simplify data consistency and make it easier to recover from failure. Also, portable applications that run on both on-premise and public cloud infrastructure ensure continuous application connectivity.

These and other capabilities support the company’s disaster recovery strategy, minimize downtime, and reduce costly business impact.


Improved security and risk management


Hybrid cloud architecture improves attack surface management because organizations can operate their security controls in a consistent and centralized manner. However, that’s only possible with technology that extends across providers.

This is why organizations prioritize proactive risk detection and automation when choosing a hybrid cloud security solution. Enterprises often end up working with companies like AlgoSec to also overcome challenges like staff shortages and keeping up with the changing cloud environment.

There’s no underestimating how complex hybrid cloud security is. Specialized research shows that fragmented security due to insufficient staff, manual management, unclear ownership, and lack of expertise is the main issue. And those are not the only obstacles.


Compliance and governance


Hybrid cloud architecture is under regulatory scrutiny given the volumes of sensitive data that pass through it. Data protection and compliance standards (e.g. HIPAA, PCI DSS, GDPR, ISO/IEC 27001, NIST, etc.) constantly evolve, pushing organizations to expand their security capabilities.

Cloud providers‘ certifications help with cloud compliance, but the “shared responsibility” model requires companies to assume more responsibility for risk management across their on-premises and multi-cloud network environments.


Visibility and control


Security owners face constant pressure to manage multiple vendors and security controls, understand network structures, track assets, and identify misconfigurations in real-time.

Since cloud providers‘ native security controls often fall short, organizations need a solution that can orchestrate security and give them full visibility and control.


Staff shortages


With scarce resources and limited specialized know-how, protecting each component of the cloud computing environment is a sizable challenge.

Since finding skilled security experts is often a struggle, enterprises must get creative with either recruitment or a technical solution that can ease the burden.


Access management


Access management is more complicated in the hybrid cloud. Each provider has different authentication methods and access policies. Users with different roles and devices request access from various locations.

It’s challenging to reduce risks such as unauthorized access, data leaks, and non-compliance by coordinating dissimilar, incompatible tools and platforms.


Supply chain security


Cybercriminals take advantage of multi-vendor hybrid cloud environments because they know companies lack visibility and control over the entire supply chain. So they target vulnerabilities and inadequate security controls to reach high-value enterprises.

Managing security risks associated with each vendor and partner remains crucial, especially since it is notoriously difficult to detect and mitigate supply chain attacks.

Security benefits of a hybrid cloud solution

Executives may believe security and IT professionals have excessive risk aversion, but their fears are valid for hybrid cloud security. Hybrid cloud environments provide attackers with multiple possible entry points to gain unauthorized access, move laterally, and steal data.


Incomplete attack surface mapping


Mapping the attack surface of hybrid workload inventories is challenging without a solution that bridges multiple environments. Limited visibility leaves organizations overexposed to bad actors who scrutinize publicly available workloads.

Without close management of every cloud asset, even unused resources can become a gateway for attackers and security threats.


Exploitable misconfiguration


Cloud security misconfigurations are a main cause of cloud-related incidents and a major concern for security and IT professionals. Left unchecked, they create security gaps that can quickly escalate and lead to full compromise.

Realistically, without smart automation, it is almost impossible to identify misconfigurations in real-time.


Data leakage


It takes a lot of heavy lifting to prevent sensitive data loss. Security teams must ensure safe storage and access to confidential information, prevent developers from circumventing approvals, curb unsanctioned API use, and avoid vulnerabilities introduced by cloud security changes.

Without a trusted solution that automates the bulk of this, their work remains taxing.


Human error


Business pressure for rapid digitalization and growth strains security experts, diverting their attention from data security. The ease of use of cloud-based apps also increases the risk of outsiders accessing assets.

Enterprises need to implement processes and technology to help employees make the right decisions, rather than blaming them for mishaps.


Security controls incompatibilities


Legacy on-premise security controls often do not work with cloud-specific ones. This makes it impossible to run a coherent policy across both sets. On top of that, cumbersome manual processes add friction and can result in connectivity failures for the entire hybrid cloud environment.

This makes it imperative to find a hybrid cloud security solution that reconciles and eliminates these differences.


Lack of operational workflows


Securing hybrid clouds often lags behind adoption, leaving the security team to struggle with overexposure and unsanctioned public cloud use.

The top contributing factors include limited resources to develop comprehensive strategies before adopting hybrid cloud architecture, steep learning curves, missing expertise, and lack of proper tooling.


Data breaches


Cybercriminals are adept at monetizing access and data, so they focus on getting both. Misconfigurations and mismanagement often give them a way into the system. Cloud security breaches also result from targeted attacks that use zero-day vulnerabilities and from hijacking accounts with weak credentials.

Without a way to quickly identify assets that violate security controls, enterprises cannot move fast enough to limit risk or potential damage.


Sharing data with external, unauthorized parties


Cloud apps make access sharing easy and unlimited, but revoking it in a centralized way is often impossible. This is why unmonitored sharing can easily spiral into uncontrolled access and data leakage.

This exposure takes a long time to detect, making it a critical threat to organizations.

What are the risks in hybrid cloud security?

Any modern security strategy for the hybrid cloud follows an automation-driven approach that combines controls that plug into physical, technical, and administrative layers.

This helps internal teams coordinate security controls and avoid errors and synchronization issues. It also provides global visibility and helps organizations monitor environments, manage data security rules, run compliance checks, roll out patches, and more.

Ultimately, this strategy enables enterprises to stay ahead of risks rather than react to them.


Physical security


Organizations handle physical security for on-premise infrastructure but lose control when working with public cloud providers. While SLAs (Service Level Agreements) also enforce physical security standards, most details remain out of their grasp. That’s why many enterprises invest in technical controls to reduce hybrid cloud risks.


Technical controls


The bulk of hybrid cloud security work involves orchestrating encryption, access control, micro-segmentation, vulnerability scanning, workload security, configuration management, and endpoint security. Automation comes into play here to ensure these technical controls meet compliance demands and keep up with business needs, keeping this intricate system compatible and effective.


Administrative controls


Training, disaster recovery, and incident response plans are fundamental administrative controls. These protocols guide internal security experts in both ongoing activities and in crisis situations.

Automation offers crucial support here too, enabling teams to quickly identify risk and use the audit trail for compliance and forensics.
