A security group is a set of rules that controls the network traffic going in and out of your virtual machines (VMs). It decides:
- What kind of incoming traffic is allowed to reach your VM.
- What kind of outgoing traffic is allowed from your VM.
Every project automatically has a default security group that allows all traffic on all ports and can’t be deleted.
You can create custom security groups with specific rules and apply them to your VMs. Any changes you make to the rules take effect right away.
Note: These rules only apply to IPv4 traffic, not IPv6.
