Description: A network security group is a set of security rules that control incoming and outgoing traffic to cloud infrastructure resources, such as those found in various cloud environments. These rules allow defining what type of traffic is permitted or denied based on criteria such as IP addresses, protocols, and ports. Security groups are fundamental for protecting cloud resources, acting as a virtual firewall that regulates access to instances and services. In the context of containers and orchestration, security groups are essential to ensure that only authorized traffic can communicate with the containers, thus ensuring the integrity and confidentiality of data. Additionally, when using Infrastructure as Code (IaC) with tools like Pulumi, security groups can be defined and managed programmatically, facilitating the implementation and maintenance of consistent security policies in cloud environments. In summary, network security groups are a critical tool for managing security in the cloud, allowing organizations to protect their applications and data from unauthorized access.
