Security Groups

Security groups can be used to control access to resources and data, and to manage network traffic:

Control access

Security groups can be used to grant users access to applications, actions, and data. For example, in Active Directory, you can assign user rights to security groups (RBAC) to determine what members of that group can do.

Manage network traffic

Security groups can be used to control the traffic that can reach and leave resources. For example, in AWS, you can create security groups with inbound and outbound rules to control traffic to and from an EC2 instance.

Protect against threats

Security groups can be used to protect against threats like credential theft, fraud, and brand impersonation.

Here are some examples of how security groups can be used:

Google Admin console

You can add the Security label to a group in the Google Admin console to make it a security group.

Azure application security groups

You can group virtual machines and define network security policies based on those groups.

AWS security groups

You can create security groups with inbound and outbound rules to control traffic to and from an EC2 instance (Virtual Machine).
