Overview

A security rule is one of the items in a NetworkSecurityGroup. It is a virtual firewall rule for the VNICs in the network security group. A rule can be for either inbound (direction= INGRESS) or outbound (direction= EGRESS) IP packets.

Instance Attribute Details

#description ⇒ String

An optional description of your choice for the rule.

Returns:

  • (String) 


37
38
39
 
# File 'lib/oci/core/models/security_rule.rb', line 37

def description
  @description
end

#destination ⇒ String

Conceptually, this is the range of IP addresses that a packet originating from the instance can go to.

Allowed values:

  • An IP address range in CIDR notation. For example: 192.168.1.0/24 or 2001:0db8:0123:45::/56 Note that IPv6 addressing is currently supported only in certain regions. See IPv6 Addresses.

  • The cidrBlock value for a OCI::Core::Models::Service, if you're setting up a security rule for traffic destined for a particular Service through a service gateway. For example: oci-phx-objectstorage.

  • The OCID of a NetworkSecurityGroup in the same VCN. The value can be the NSG that the rule belongs to if the rule's intent is to control traffic between VNICs in the same NSG.

Returns:

  • (String) 


57
58
59
 
# File 'lib/oci/core/models/security_rule.rb', line 57

def destination
  @destination
end

#destination_type ⇒ String

Type of destination for the rule. Required if direction = EGRESS.

Allowed values:

  • CIDR_BLOCK: If the rule's destination is an IP address range in CIDR notation.

  • SERVICE_CIDR_BLOCK: If the rule's destination is the cidrBlock value for a OCI::Core::Models::Service (the rule is for traffic destined for a particular Service through a service gateway).

  • NETWORK_SECURITY_GROUP: If the rule's destination is the OCID of a NetworkSecurityGroup.

Returns:

  • (String) 


73
74
75
 
# File 'lib/oci/core/models/security_rule.rb', line 73

def destination_type
  @destination_type
end

#direction ⇒ String

[Required] Direction of the security rule. Set to EGRESS for rules to allow outbound IP packets, or INGRESS for rules to allow inbound IP packets.

Returns:

  • (String) 


77
78
79
 
# File 'lib/oci/core/models/security_rule.rb', line 77

def direction
  @direction
end

#icmp_options ⇒ OCI::Core::Models::IcmpOptions

Optional and valid only for ICMP and ICMPv6. Use to specify a particular ICMP type and code as defined in: - ICMP Parameters - ICMPv6 Parameters

If you specify ICMP or ICMPv6 as the protocol but omit this object, then all ICMP types and codes are allowed. If you do provide this object, the type is required and the code is optional. To enable MTU negotiation for ingress internet traffic via IPv4, make sure to allow type 3 ("Destination Unreachable") code 4 ("Fragmentation Needed and Don't Fragment was Set"). If you need to specify multiple codes for a single type, create a separate security rule for each.

Returns:



91
92
93
 
# File 'lib/oci/core/models/security_rule.rb', line 91

def icmp_options
  @icmp_options
end

#id ⇒ String

An Oracle-assigned identifier for the security rule. You specify this ID when you want to update or delete the rule.

Example: 04ABEC

Returns:

  • (String) 


99
100
101
 
# File 'lib/oci/core/models/security_rule.rb', line 99

def id
  @id
end

#is_stateless ⇒ BOOLEAN

A stateless rule allows traffic in one direction. Remember to add a corresponding stateless rule in the other direction if you need to support bidirectional traffic. For example, if egress traffic allows TCP destination port 80, there should be an ingress rule to allow TCP source port 80. Defaults to false, which means the rule is stateful and a corresponding rule is not necessary for bidirectional traffic.

Returns:

  • (BOOLEAN) 


108
109
110
 
# File 'lib/oci/core/models/security_rule.rb', line 108

def is_stateless
  @is_stateless
end

#is_valid ⇒ BOOLEAN

Whether the rule is valid. The value is True when the rule is first created. If the rule's source or destination is a network security group, the value changes to False if that network security group is deleted.

Returns:

  • (BOOLEAN) 


115
116
117
 
# File 'lib/oci/core/models/security_rule.rb', line 115

def is_valid
  @is_valid
end

#protocol ⇒ String

[Required] The transport protocol. Specify either all or an IPv4 protocol number as defined in Protocol Numbers. Options are supported only for ICMP ("1"), TCP ("6"), UDP ("17"), and ICMPv6 ("58").

end

#source ⇒ String

Allowed values:

  • An IP address range in CIDR notation. For example: 192.168.1.0/24 or 2001:0db8:0123:45::/56 Note that IPv6 addressing is currently supported only in certain regions. See IPv6 Addresses.

  • The cidrBlock value for a OCI::Core::Models::Service, if you're setting up a security rule for traffic coming from a particular Service through a service gateway. For example: oci-phx-objectstorage.

  • The OCID of a NetworkSecurityGroup in the same VCN. The value can be the NSG that the rule belongs to if the rule's intent is to control traffic between VNICs in the same NSG.

Returns:

  • (String)

# File 'lib/oci/core/models/security_rule.rb', line 143

def source
  @source
end

#source_type ⇒ String

Type of source for the rule. Required if direction = INGRESS.

  • CIDR_BLOCK: If the rule's source is an IP address range in CIDR notation.

  • SERVICE_CIDR_BLOCK: If the rule's source is the cidrBlock value for a OCI::Core::Models::Service (the rule is for traffic coming from a particular Service through a service gateway).

  • NETWORK_SECURITY_GROUP: If the rule's source is the OCID of a NetworkSecurityGroup.

#udp_options ⇒ OCI::Core::Models::UdpOptions

Optional and valid only for UDP. Use to specify particular destination ports for UDP rules. If you specify UDP as the protocol but omit this object, then all destination ports are allowed.
