chmod 400 key-pair-name.pem
```
# Create a security group
:::info
- Security groups act as a firewall for associated instances, controlling both inbound and outbound traffic at the instance level.
- You must add rules to a security group that enable you to connect to your instance from your IP address using SSH.
- If you plan to launch instances in multiple Regions, you'll need to create a security group in each Region.

- Use the following rules for a web server that accepts HTTP and HTTPS traffic.
- Adding following rules for **Inbound rules**
| Type | Source |
| ----- | -------- |
| HTTP | Anywhere |
