methodpublicauthorizeGroup( string $name, string $groupName, string $ownerId ) : boolean

Adds permissions to a security group

When authorizing a user/group pair permission, GroupName, SourceSecurityGroupName and SourceSecurityGroupOwnerId must be specified.

Permission changes are propagated to instances within the security group as quickly as possible. However, depending on the number of instances, a small delay might occur.

Parameters
Name Type Description
$name string Name of the group to modify.
$groupName string

methodpublicauthorizeIp( string $name, string $ipProtocol, integer $fromPort, integer $toPort, string $cidrIp ) : boolean

Adds permissions to a security group

Permissions are specified by the IP protocol (TCP, UDP or ICMP), the source of the request (by IP range or an Amazon EC2 user-group pair), the source and destination port ranges (for TCP and UDP), and the ICMP codes and types (for ICMP). When authorizing ICMP, -1 can be used as a wildcard in the type and code fields.

Permission changes are propagated to instances within the security group as quickly as possible. However, depending on the number of instances, a small delay might occur.

Parameters
Name Type Description
$name string Name of the group to modify.
$ipProtocol string IP protocol to authorize access to when operating on a CIDR IP.
$fromPort integer Bottom of port range to authorize access to when operating on a CIDR IP. This contains the ICMP type if ICMP is being authorized.
$toPort integer Top of port range to authorize access to when operating on a CIDR IP. This contains the ICMP code if ICMP is being authorized.
$cidrIp string CIDR IP range to authorize access to when operating on a CIDR IP.
Returns
Type Description
boolean

As the owner of instances you can grant or revoke specific permissions using the {@link authorizeIp}, {@link authorizeGroup}, {@link revokeGroup} and {$link revokeIp} operations.

Parameters

For example, if security group B has a rule that allows access from security group A, security group A cannot be deleted until the allow rule is removed.

Parameters
Name Type Description
