Cross-Container Data Leakage
Cross-Container Data Leakage is a cyber security concern which arises when data is shared between multiple computing containers in a system. Containers are like virtual compartments that hold different software applications or processes. In a system that uses multiple containers, data can flow between them, and if not properly controlled, one container can access data from another container that it shouldn’t be able to access. This can happen due to flaws in the container management software or if the user improperly configures the containers.
For example, say you have a system with two containers; one running your email application and another running your banking application. If the containers are properly configured, the email container can’t access data from the banking container. However, if there is a cross-container data leakage vulnerability, the email container could theoretically access data from the banking container, which could result in the theft of sensitive banking information.
To prevent cross-container data leakage, proper security practices need to be implemented, such as segmenting the containers, controlling data access permissions, and regularly updating and patching the software.
