Working with Security Group​

The following sections describe how you can use Security Group.

  • Inbound Rules: By default, a security group includes an inbound rule that allows all inbound traffic. We recommend that you remove this default rule and add inbound rules that allow specific inbound traffic only.

  • Outbound Rules: By default, a security group includes an outbound rule that allows all outbound traffic. We recommend that you remove this default rule and add outbound rules that allow specific outbound traffic only.

  • Name: Security group name must contain only alphabetic characters (a–z, A–Z). Spaces, numbers, and special characters are not allowed. Maximum length: 128 characters.

  • Protocol: Defines the type of network traffic to allow, such as TCP for reliable connections, UDP for fast data transfer, and ICMP for network diagnostics. Options include All, All TCP, All UDP, Custom TCP, Custom UDP, and ICMP.

  • Port Range: For Custom TCP or Custom UDP, specify the ports to allow. You can enter a single port (e.g., 22, 443) or a range (e.g., 1000–2000) based on the service requirements.

  • Network: The Network field determines where traffic is allowed from (inbound) or to (outbound).

    • Any Network: Allows traffic from/to all IP addresses (0.0.0.0/0).
    • Manual Network: Manually specify an IP address and CIDR size (e.g., 192.168.1.0/24).
    • VPC Network: Restrict traffic to/from a selected VPC.
