However, there are a few endemic security issues that cybersecurity teams are often faced with, as follows:
Enterprises purchase SaaS or IaaS services from different vendors for different business functions. When this happens, cybersecurity teams are unable to apply a unified set of data use policies. They are unable to set access control protocols to execute across all the cloud applications purchased from different vendors. As a result, when critical data passes from one cloud to another, the security rules governing it may change, leading to potential data leaks and misuse. And conventional cybersecurity solutions are often unable to provide network-wide protection to multiple cloud solutions.
A key reason why enterprises adopt multi-cloud -- or cloud in general -- is to enable employees the freedom to access business applications and data from anywhere and any device. This allows the employees to have greater flexibility and productivity. However, the use of a multi-cloud approach leads to the inability to have total visibility over the different applications and devices that may be introduced into the enterprise network by users. Even if each separate cloud service is secure, the combined whole of different clouds that makes up the enterprise network cannot be secure. That is unless a single, uniform security system is used to govern the entire network.
Thus, it is vital for enterprises to use a next-generation firewall solution with Cloud Access Security Broker (CASB) functionality. CASB is a scalable and secure way of protecting all your cloud applications under a single set of security policies. It offers a unified platform that brings together all your cloud data and services to provide total visibility into the enterprise network. CASB solutions can help you mitigate multi-cloud security risks by notifying cybersecurity professionals about potential risks as they emerge. They can even prevent harmful cybersecurity incidents such as hacks and data leaks before they happen, regardless of the complexity of the enterprise’s IT architecture.
