Overview of Cloud Native Security Services from AWS

Security plays an important role for any industry as every day there is news of another massive data breach in many places. Security is a core functional requirement to protect critical information, manage the access, logging and monitoring. Hence organization spend significant amount of resources to manage the security of their resources whether it is in physical or virtual (in-cloud).
