Multicloud and hybrid cloud environments have become increasingly common in various industries. Organizations may choose to work with multiple cloud service providers (CSPs) for enhanced flexibility, or they may find themselves in a multicloud setup due to a merger or acquisition. However, these complex environments come with their own set of security challenges that need to be addressed.
One of the major security concerns in multicloud and hybrid cloud environments is the issue of “security at the seams.” While individual clouds may have strong security measures in place, vulnerabilities can emerge at the edges where the clouds connect to each other or to local servers and remote services. In order to fully benefit from the advantages of a multicloud setup, data must be able to move smoothly and securely, and applications that connect to multiple clouds need to be designed and built with security in mind. This includes considerations such as encrypting data during transit and effective privilege management.
Furthermore, the use of multiple CSPs adds an additional layer of complexity. Acquiring skills to manage a single cloud environment can be challenging enough, but mastering multiple private and public clouds requires a broader range of expertise. Each cloud environment has its own unique set of security practices and quirks, and any interaction between distinct clouds must be carefully managed. To ensure the security of sensitive data flowing through a complex multicloud environment, organizations must have a team of security specialists with deep knowledge of the technology stacks used by each CSP. This requires prioritizing training and hiring decisions to ensure expertise in the relevant specialties for the multicloud environment.
In securing multicloud environments, it is crucial to utilize cloud-native tools whenever possible. While legacy tools may have been sufficient in the past, they are often inadequate for securing a single cloud environment and fall short when it comes to multicloud setups. The major cloud service providers offer specialized tools designed to protect their own clouds, and leveraging these tools is essential for properly securing the multicloud environment. Cloud-native security tools should be an integral part of any organization’s cloud migration plan, as they offer cost-efficiency, easier management, and higher reliability compared to legacy security tools used across multiple clouds.
Open source technologies also play a significant role in enabling multicloud environments. They facilitate efficient workflows and data movement, reducing dependence on a limited number of third-party providers. Implementing a multicloud-based open source strategy can enhance an organization’s compliance posture by providing strong data governance and mobility capabilities.
As multicloud and hybrid cloud environments become the new standard for modern businesses, security tools are continually advancing to meet the evolving needs. The zero-trust security model, for example, is highly suitable for defending complex cloud networks. It focuses on limiting the scope and damage of potential intrusions by assuming that no device or user should be trusted by default. This principle helps organizations identify and mitigate vulnerabilities in their cloud environment and provides a more robust defense against malicious actors.
The integration of artificial intelligence (AI) and machine learning into security tasks is another significant development in multicloud security. AI-powered security tools contribute to the concept of “invisible security,” where data and networks are protected with minimal human involvement. These automated tools can monitor and defend systems round the clock, freeing up security teams to focus on higher-level tasks such as assessing and auditing security measures, professional development, and promoting security awareness across the organization.
In conclusion, as multicloud and hybrid cloud environments become increasingly prevalent, organizations must pay close attention to the unique security considerations that come with these setups. By addressing “security at the seams,” leveraging cloud-native security tools, and staying updated with advancements in multicloud security, businesses can ensure the protection of their valuable data and maintain a secure cloud environment.
