Security
Adds the specified outbound (egress) rule to a security group. An outbound rule permits instances to send traffic to the specified IPv4 or IPv6 address range, the IP addresses that are specified by a prefix list, or the instances that are associated with a destination security group. For more information, see Security group rules. You must specify exactly one of the following destinations: an IPv4 address range, an IPv6 address range, a prefix list, or a security group. You must specify a protocol for each rule (for example, TCP). If the protocol is TCP or UDP, you must also specify a port or port range. If the protocol is ICMP or ICMPv6, you must also specify the ICMP/ICMPv6 type and code. To specify all types or all codes, use -1. Rule changes are propagated to instances associated with the security group as quickly as possible. However, a small delay might occur.

Properties
The IPv4 address range, in CIDR format. You must specify exactly one of the following: `CidrIp`, `CidrIpv6`, `DestinationPrefixListId`, or `DestinationSecurityGroupId`. For examples of rules that you can add to security groups for specific access scenarios, see Security group rules for different use cases in the User Guide.
The IPv6 address range, in CIDR format. You must specify exactly one of the following: `CidrIp`, `CidrIpv6`, `DestinationPrefixListId`, or `DestinationSecurityGroupId`. For examples of rules that you can add to security groups for specific access scenarios, see Security group rules for different use cases in the User Guide.
The description of an egress (outbound) security group rule. Constraints: Up to 255 characters in length. Allowed characters are a-z, A-Z, 0-9, spaces, and ._-:/()#,@[]+=;{}!$*
The prefix list IDs for an AWS service. This is the AWS service to access through a VPC endpoint from instances associated with the security group. You must specify exactly one of the following: `CidrIp`, `CidrIpv6`, `DestinationPrefixListId`, or `DestinationSecurityGroupId`.
The ID of the security group. You must specify exactly one of the following: `CidrIp`, `CidrIpv6`, `DestinationPrefixListId`, or `DestinationSecurityGroupId`.
The IP protocol name (`tcp`, `udp`, `icmp`, `icmpv6`) or number (see Protocol Numbers). Use `-1` to specify all protocols. When authorizing security group rules, specifying `-1` or a protocol number other than `tcp`, `udp`, `icmp`, or `icmpv6` allows traffic on all ports, regardless of any port range you specify. For `tcp`, `udp`, and `icmp`, you must specify a port range. For `icmpv6`, the port range is optional; if you omit the port range, traffic for all types and codes is allowed.
