☁️ Cloud infrastructure has benefits such as flexibility, scalability, high performance, and affordability. Once you subscribe to a service, such as the Google Cloud Platform (GCP), you do not have to worry about the high capital and maintenance costs of an equivalent in-house data center and associated infrastructure. However, traditional on-premise security practices do not provide sufficient and prompt security for virtual environments.
Unlike an on-premise data center where perimeter security protects the entire installation and resources, the nature of the cloud environment, with diverse technologies and locations, requires a different approach. Usually, the decentralized and dynamic nature of the cloud environment leads to an increased attack surface.
In particular, misconfigurations on the cloud platforms and components expose the assets while increasing the hidden security risks. Sometimes, developers may open a data store when developing a piece of software but then leave it open when releasing the application to the market.
As such, in addition to following security best practices, there is a need to ensure proper configurations as well as the ability to provide continuous monitoring, visibility, and compliance.
Luckily, there are several tools to help you improve security by detecting and preventing misconfigurations, providing visibility into the security posture of the GCP as well as identifying and addressing other vulnerabilities.
Update: for the AWS security scanner, check out this post.
