Enterprise Interest in Zero Trust is Growing Ransomware and breaches are top of the news cycle and a major concern for organizations big and small. So, many are now looking at the Zero Trust architecture and its primary principle "never trust, always verify" to provide greater protection.
According to Report Linker, the Zero Trust security market is projected to grow from USD 15.6 billion in 2019 to USD 38.6 billion by 2024 and that sounds right based on the large number of companies pitching their Zero Trust wares at RSA 2020.
The enterprise was well represented at the conference and there was a tremendous amount of interest in Zero Trust. Interestingly, even though Zero Trust environments are often made up of several solutions from multiple vendors it hasn't prevented each of the vendors from evangelizing their flavors of Zero Trust. This left the thousands of attendees to attempt to cut through the Zero Trust buzz and noise and make their own conclusions to the best approach.

DYNAMIC GROUP
Dynamic groups allow you to group Oracle Cloud Infrastructure instances as principal actors, similar to user groups. You can then create policies to permit instances in these groups to make API calls against Oracle Cloud Infrastructure services. Membership in the group is determined by a set of criteria you define, called matching rules. https://docs.cloud.oracle.com/en-us/iaas/Content/Identity/Tasks/callingservicesfrominstances.htm
