Organizations are rapidly evolving into their digital transformation journey, and these organizations often have a multi-cloud strategy. Multi-cloud gives companies the ability to use many different clouds for better flexibility, resilience, scalability, and performance. Through the use of multiple clouds, companies can prevent being locked into a single vendor, manage costs more effectively, and ensure that workloads are deployed where they can operate the best.
However, with a multi-cloud environment comes many new challenges for cybersecurity. Ensuring that an organization has consistent security across multiple platforms results in significant complexities, increasing the chances of experiencing misconfigurations, gaps in visibility, difficulties with compliance and regulatory requirements, etc.
To keep an organization secure, they must first get a clear understanding of the specific risks associated with operating in a multi-cloud environment and take appropriate action to mitigate or eliminate those risks.
Multi-cloud is the term that describes when a company utilizes at least two different providers’ hosted services to run applications, keep data, or perform business operations.
As a result of this approach, organizations have greater diversity in their operational ability; they have more choices regarding who provides their infrastructure, storage, analytics, disaster recovery, and other specialized functions. While multi-cloud increases operational flexibility, organizations will likely find themselves needing to manage more than one set of security functions and, as such, will need to monitor and protect them all at the same time.
Maintaining visibility into various clouds in a multi-cloud environment is one of the most difficult tasks. The cloud provider’s monitoring tool, security controls, and management interfaces are all unique to that particular provider. A lack of a centralized way to view all the cloud providers’ clouds will make it difficult for the security team to identify potential threats, track user activity, and detect unusual activity throughout the entire environment. This leads to extended detection times due to these blind spots which can create a higher potential for a successful attack.
Cloud misconfigurations remain one of the leading causes of cloud security incidents. In multi-cloud environments, managing security settings across multiple platforms becomes increasingly complex. Incorrectly configured storage services, overly permissive access controls, exposed APIs, and unsecured workloads can create vulnerabilities that attackers actively exploit. As cloud environments grow, maintaining consistent security configurations becomes even more challenging.
Identity/permissions management in multi-cloud environments can be challenging because providers tend to have different identity management frameworks, policies, and access controls. Lack of governance can lead to excessive user privileges, orphan accounts, inconsistent authentication policies, and risks of unauthorized access. Compromised credentials are a significant risk factor in multi-cloud environments.
Organizations in regulated sectors need to always protect their data irrespective of the location of their storage / processing. Multi-cloud environments create additional challenges on the regulatory side due to multiple variations in security controls, data residency requirements, and the ability to report compliance issues. To remain compliant across multiple Cloud Providers, organizations will need to have strong governance, continuous monitoring, and regular security evaluations.
Business and customer information that is sensitive can be stored in a number of different cloud services. If you do not have sufficient controls in place, your business will lose visibility over how the information is accessed, shared, and stored. Thus, it is critical for you to implement safeguards against unauthorized access and/or breaches by enabling some method of encrypting your data, using appropriate and effective access, access logging, monitoring, and proper ways to manage the lifecycle of that data.
When security incidents occur in multi-cloud environments, investigation and response efforts can become more complicated. Security teams may need to collect logs, analyze events, and coordinate responses across several cloud platforms simultaneously. Without centralized monitoring and incident response processes, organizations may face longer response times and reduced effectiveness during security incidents.
Having a strong governance framework is very important to support multi-cloud environments. Organizations need to put into place standardized security policies, access control methodologies, monitoring practices and risk management protocols that are consistently applied across each of their cloud service providers' services. Well-defined governance frameworks will provide a reduction of complexity in multi-cloud environments, improve visibility across all clouds, and ensure that security is aligned with business objectives.
Organizations can benefit from a flexible and scalable multi-cloud environment; however, using multiple cloud services creates significant security risks and must be managed appropriately. Organizations face risk from several major areas of concern: gaps in visibility; incorrect configuration of cloud services; and complexities related to identity; in addition, many organizations must comply with local, regional and/or federal standards for data protection. Organizations can use multi-cloud technologies with confidence by implementing effective governance; centrally monitoring all assets, applications, and services; and using proactive, effective, and adaptive security controls to maintain a secure and resilient environment throughout their use of multi-cloud services.
Organizations to secure their multi cloud environments can obtain several cloud security assessments from Ancrew Global Services which include; security monitoring, identity and access management, compliance support, and vulnerability assessment services. Because of this, businesses have increased visibility and decreased risk across complicated cloud environments. Thus, ensuring that all an organization's applications delivered from various cloud providers are similarly secured.
