Description: A Security Group is a collection of user accounts that can be managed as a single entity for security purposes. This grouping allows administrators to apply security policies more efficiently and consistently, facilitating the management of permissions and access to resources within an IT infrastructure. Security Groups are fundamental in various IT environments, including cloud and virtualization, where managing multiple users and their permissions can become complex. By using Security Groups, rules can be defined that apply to all group members, simplifying administration and enhancing the overall security of the system. Additionally, these groups can be used to segment access to different resources, ensuring that only authorized users have access to sensitive information or critical system functions. In summary, Security Groups are an essential tool for managing security in modern IT environments, allowing for more effective administration and better protection of digital assets.
