The 5-tuple criteria for AWS Network Firewall to use to inspect packet headers in stateful traffic flow inspection.

Traffic flows that match the criteria are a match for the corresponding stateful rule.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_networkfirewall as networkfirewall } from 'aws-cdk-lib';
const headerProperty: networkfirewall.CfnRuleGroup.HeaderProperty = {
  destination: 'destination',
  destinationPort: 'destinationPort',
  direction: 'direction',
  protocol: 'protocol',
  source: 'source',
  sourcePort: 'sourcePort',
};

Properties

NameTypeDescription
destinationstringThe destination IP address or address range to inspect for, in CIDR notation.
destinationPortstringThe destination port to inspect for.
directionstringThe direction of traffic flow to inspect.
protocolstringThe protocol to inspect for.
sourcestringThe source IP address or address range to inspect for, in CIDR notation.
sourcePortstringThe source port to inspect for.

destination

Type: string

The destination IP address or address range to inspect for, in CIDR notation.

To match with any address, specify ANY .

Specify an IP address or a block of IP addresses in Classless Inter-Domain Routing (CIDR) notation. Network Firewall supports all address ranges for IPv4 and IPv6.

Examples:

  • To configure Network Firewall to inspect for the IP address 192.0.2.44, specify 192.0.2.44/32 .
  • To configure Network Firewall to inspect for IP addresses from 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24 .
  • To configure Network Firewall to inspect for the IP address 1111:0000:0000:0000:0000:0000:0000:0111, specify 1111:0000:0000:0000:0000:0000:0000:0111/128 .
  • To configure Network Firewall to inspect for IP addresses from 1111:0000:0000:0000:0000:0000:0000:0000 to 1111:0000:0000:0000:ffff:ffff:ffff:ffff, specify 1111:0000:0000:0000:0000:0000:0000:0000/64 .

For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing .


destinationPort

Type: string

The destination port to inspect for.

You can specify an individual port, for example 1994 and you can specify a port range, for example 1990:1994 . To match with any port, specify ANY .


direction

Type: string

The direction of traffic flow to inspect.

If set to ANY , the inspection matches bidirectional traffic, both from the source to the destination and from the destination to the source. If set to FORWARD , the inspection only matches traffic going from the source to the destination.


protocol

Type: string

The protocol to inspect for.

To specify all, you can use IP , because all traffic on AWS and on the internet is IP.


source

Type: string

The source IP address or address range to inspect for, in CIDR notation.

To match with any address, specify ANY .

Specify an IP address or a block of IP addresses in Classless Inter-Domain Routing (CIDR) notation. Network Firewall supports all address ranges for IPv4 and IPv6.

Examples:

  • To configure Network Firewall to inspect for the IP address 192.0.2.44, specify 192.0.2.44/32 .
  • To configure Network Firewall to inspect for IP addresses from 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24 .
  • To configure Network Firewall to inspect for the IP address 1111:0000:0000:0000:0000:0000:0000:0111, specify 1111:0000:0000:0000:0000:0000:0000:0111/128 .
  • To configure Network Firewall to inspect for IP addresses from 1111:0000:0000:0000:0000:0000:0000:0000 to 1111:0000:0000:0000:ffff:ffff:ffff:ffff, specify 1111:0000:0000:0000:0000:0000:0000:0000/64 .

sourcePort

Type: string

The source port to inspect for.

You can specify an individual port, for example 1994 and you can specify a port range, for example 1990:1994 . To match with any port, specify ANY .
