Challenges of Multicloud Solution Management and Security

November 6, 2019

Not all clouds are created equal, at least not in terms of security.

Companies switching cloud services or adopting cloud services must be fully aware of the capabilities and risks of every cloud services software available to them.  

Multicloud environments are incredibly popular today; according to a
survey conducted by IBM, 85% of companies use multicloud environments. The same survey revealed 98% of companies plan to adopt multiple hybrid clouds by 2021. 

While multicloud environments are elastic and customizable, multicloud requires additional scrutiny and dedicated management. Companies must configure and integrate various cloud services properly to avoid attacks, data leaks, and security breaches.

There’s good reason so many companies are considering multicloud solutions, most obviously, to avoid putting all their eggs in one basket. In other words, companies are looking to multicloud to boost their overall efficiency and cut spending. That holds true for the most part; however, a properly secured multicloud environment requires additional effort and technology. 

While nearly half (48%) of corporate data is stored in the cloud, only 32% of organizations admit they employ a security-first approach to data storage in the cloud, according to a report from the Thales Group

This is concerning. 

Companies must prioritize security above everything for the sake of their business and their customers. Without it, cloud services open businesses up to unlimited threats that can result in data loss, steep fines, or theft of proprietary information. 

Multicloud vs. other cloud environments

Before we dive in to the challenges associated with multicloud environments, let’s differentiate multicloud systems from other common cloud services. 

Public cloud — The public cloud is utilized through cloud service providers like AWS, Microsoft Azure, or Google Cloud. These various services run on the provider’s infrastructure and typically use a pay-per-use model. They eliminate the need for businesses to manage infrastructure and shared resources.

Private cloud — Private clouds are the simplest cloud environments one can imagine, operating within a company’s own network. Private clouds require localized infrastructure and management. Many cloud services providers offer virtual private clouds, which are isolated, virtualized cloud environments running on public cloud infrastructure.

Hybrid cloud — Hybrid cloud environments combine aspects of public and private cloud environments. Businesses typically utilize public cloud resources for major operations, but store sensitive data on local, private infrastructure. Hybrid clouds can be some of the most flexible solutions, but can also be some of the most difficult to manage.

Multicloud — Multicloud environments utilize multiple cloud environments for specific tasks and operations. Unlike hybrid cloud environments, multicloud environments might use multiple public or private clouds, or a combination of the two. These individual clouds typically operate independently. For example, a multicloud environment might run all computing activities from one cloud service provider, databases from another service provider, and utilize local infrastructure to store sensitive data. 

The Case for Multicloud Adoption: Vendor lock-in reduction, best of breed-driven innovation, improved data security, compliance adherence, latency reduction.

Common issues with multicloud security

While multicloud environments provide a myriad of benefits, there are numerous threats and issues that may arise as a result of multicloud adoption.

Access control — One of the simplest ways for someone to obtain sensitive information is by misusing permissions granted by an administrator. Social engineering makes stealing credentials as easy as sending a phishing email. Proper network access control management across multiple cloud environments requires continuous monitoring of permissions and user behavior. Companies must ensure only approved parties interact with sensitive data while certifying no data is moved from a secure location to a vulnerable environment.

Authentication — Even with access control and identity management, companies should still enforce multiple layers of authentication on every cloud service that stores sensitive data. The easiest way to do this is utilizing multi-factor authentication (MFA) tools that require secondary verification via SMS code, key generator, or email. Additionally, risk-based solutions take multiple risk factors such as location, behavior, or permissions into account. These types of software are becoming more common as they consider numerous variables to mitigate risk. 

Compliance — With multiple cloud environments interacting with business information, it can be difficult to ensure every piece of sensitive data is properly labeled and secured. Various municipalities have specific regulations that pertain to data privacy and security compliance. A company must ensure the information they store is compliant in every location they conduct business. 

Vulnerability management — Applications and networks require frequent testing and scanning for vulnerabilities. Otherwise, firewalls or other security mechanisms could be easily bypassed with something as simple as SQL injection. In addition to traditional vulnerability scanners, companies should utilize threat intelligence software to ensure their cloud resources are protected from the most advanced threats on the internet. 

Best practices for multicloud security systems

Centralized visibility — Multicloud environments have numerous moving parts and siloed systems. This makes it difficult for businesses to paint a full picture of every cloud service they use, how they are connected, and who has access to them. Numerous tools have been introduced in recent years that enable companies to gain visibility into their multicloud environments. Cloud management platforms are the easiest way for companies to centralize control of various clouds and enforce compliance across multicloud environments. 

Workload protection — Workloads are the functions and resources that run in a cloud environment. In a multicloud scenario, these often operate independently and require individual attention. Cloud workload protection platforms help ensure each individual workload is properly configured and vulnerabilities are accounted for. They also assist in behavior monitoring to detect misuse and intrusions. 

Data governance — Because 21% of files in the cloud contain sensitive data, it’s incredibly important to maintain continuous visibility of datastores. If you don’t use them already, consider data-centric security solutions to simplify the discovery and tagging of sensitive information. Cloud compliance software can also help manage security and compliance policies across cloud workloads. 

Policy enforcement — Policy enforcement and configuration management are some of the most difficult tasks associated with managing a multicloud environment. These policies include a combination of security measures to facilitate access control, protect environments, secure sensitive data, and prevent misuse. Each security mechanism that protects various cloud environments requires specific configurations for its individual cloud service and use case. Misconfigurations can expand the likelihood of an attack; furthermore, poor security policies and misconfigurations open up cloud environments to a plethora of threats.
