Cloud Security Groups
Cloud Security Groups are a fundamental network security feature in cloud computing platforms that act as virtual firewalls to control inbound and outbound traffic for cloud resources, such as virtual machines or containers. They operate at the instance level by defining rules that allow or deny traffic based on protocols, ports, and IP addresses, providing a stateful and dynamic way to enforce security policies in cloud environments.
Developers should learn and use Cloud Security Groups when deploying applications in cloud platforms like AWS, Azure, or Google Cloud to secure their infrastructure by restricting unauthorized access and preventing data breaches. They are essential for implementing the principle of least privilege in network security, such as allowing only specific ports for web servers or database connections, and are commonly used in scenarios like microservices architectures, multi-tier applications, and compliance-driven deployments.
