CfnSecurityGroupPropsMixin

class aws_cdk.mixins_preview.aws_ec2.mixins.CfnSecurityGroupPropsMixin(props, *, strategy=None)

Bases: Mixin

Specifies a security group.

You must specify ingress rules to allow inbound traffic. By default, no inbound traffic is allowed.

When you create a security group, if you do not add egress rules, we add egress rules that allow all outbound IPv4 and IPv6 traffic. Otherwise, we do not add them. After the security group is created, if you remove all egress rules that you added, we do not add egress rules, so no outbound traffic is allowed.

If you modify a rule, CloudFormation removes the existing rule and then adds a new rule. There is a brief period when neither the original rule or the new rule exists, so the corresponding traffic is dropped.

This type supports updates. For more information about updating stacks, see AWS CloudFormation Stacks Updates . .. epigraph:

To cross-reference two security groups in the ingress and egress rules of those security groups, use the `AWS::EC2::SecurityGroupEgress <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-security-group-egress.html>`_ and `AWS::EC2::SecurityGroupIngress <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-security-group-ingress.html>`_ resources to define your rules. Do not use the embedded ingress and egress rules in the ``AWS::EC2::SecurityGroup`` . Doing so creates a circular dependency, which CloudFormation doesn't allow.

Bases: object

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 address ranges 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.

Rule changes are propagated to instances associated with the security group as quickly as possible. However, a small delay might occur.

Parameters:

cidr_ip (Optional[str]) – 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 Amazon EC2 User Guide .
cidr_ipv6 (Optional[str]) –
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 Amazon EC2 User Guide .
description (Optional[str]) – A description for the security group rule. Constraints: Up to 255 characters in length. Allowed characters are a-z, A-Z, 0-9, spaces, and ._-:/()#,@[]+=;{}!$*
destination_prefix_list_id (Optional[str]) – The prefix list IDs for the destination AWS service. This is the AWS service that you want 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 .
destination_security_group_id (Optional[str]) – The ID of the destination VPC security group. You must specify exactly one of the following: CidrIp , CidrIpv6 , DestinationPrefixListId , or DestinationSecurityGroupId .
from_port (Union[int, float, None]) – If the protocol is TCP or UDP, this is the start of the port range. If the protocol is ICMP or ICMPv6, this is the ICMP type or -1 (all ICMP types).
ip_protocol (Optional[str]) – 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.
to_port (Union[int, float, None]) – If the protocol is TCP or UDP, this is the end of the port range. If the protocol is ICMP or ICMPv6, this is the ICMP code or -1 (all ICMP codes). If the start port is -1 (all ICMP types), then the end port must be -1 (all ICMP codes).
