How to protect yourself in a multi cloud environment?

As companies expect to be more agile and flexible while saving money by moving their workloads to the cloud, the trend towards multi cloud is gaining ground. Initially, 86% of IT administrators already use multiple clouds. While the vast majority of the rest plan to adopt it in the next few years. Either way, security remains a major challenge in this decision. It is still possible to find a solution based on best practices related to improving security in the cloud age.

Ensure safety at the workload level

Separating cloud-stored workloads from underlying hardware is a fundamental change in protection. This is because containers and virtual machines can move freely between on-premises infrastructures and the public network. Specifically, workloads share physical hosts and internal network resources with unknown third parties. Therefore, this phenomenon constitutes a real danger for the notion of network perimeter.


To guarantee security in this type of architecture, it is essential to protect the equipment. Protection measures must be defined at the software level, among others, application firewalls and intrusion prevention systems. They must also be registered at the workload, container, or virtual machine level. Other than that, ensuring data protection regardless of operating system requires decoupling security from hardware and workloads.


Play in the balance between control and cyber hygiene

In cyber security, the balance between security and ease of use is well known. There are, for example, the blocking of TCP ports, the blocking of the image of the workstation or the denial of administrator rights to users that allow to avoid actions that could compromise security. You should know that these static measurements cannot be adapted to the multi cloud era. In addition to interfering with the user experience, they are insufficient against possible threats since the environment is more complex. Therefore, it is important to find a complex compromise such as a cyber-hygiene-focused approach. This is aimed at continuously monitoring and evaluating all technology services and the IT environment.


Conduct an internal audit from the start

The notion of multi-vendor controlled infrastructure is sometimes incompatible with the control efforts of a company's IT department. However, during internal audits, it is critical that a company justifies compliance of external vendor operations with requirements as well as internal security standards. Therefore, this obstacle can damage the reputation of the department, but especially IT security. Therefore, it is important to conduct an internal audit in advance to define the selection and design process. This decision can prevent all kinds of problems in the future.
