bigip_firewall_dos_vector – Manage attack vector configuration in an AFM DoS profile

New in version 2.8.

Synopsis

Manage attack vector configuration in an AFM DoS profile. In addition to the normal AFM DoS profile vectors, this module can manage the device-configuration vectors. See the module documentation for details about this method.

Requirements

The below requirements are needed on the host that executes this module.

BIG-IP >= v13.0.0

Parameters

Parameter		Choices/Defaults	Comments
allow_advertisement boolean		Choices: no yes	Specifies that addresses that are identified for blacklisting are advertised to BGP routers
attack_ceiling string			Specifies the absolute maximum allowable for packets of this type. This setting rate limits packets to the packets per second setting, when specified. To set no hard limit and allow automatic thresholds to manage all rate limiting, set this to `infinite`.
attack_floor string			Specifies packets per second to identify an attack. These settings provide an absolute minimum of packets to allow before the attack is identified. As the automatic detection thresholds adjust to traffic and CPU usage on the system over time, this attack floor becomes less relevant. This value may not exceed the value in `attack_floor`.
auto_blacklist boolean		Choices: no yes	Automatically blacklists detected bad actors. To enable this parameter, the `bad_actor_detection` must also be enabled. This parameter is not supported by the `dns-malformed` vector. This parameter is not supported by the `qdcount` vector.
bad_actor_detection boolean		Choices: no yes	Whether Bad Actor detection is enabled or disabled for a vector, if available. This parameter must be enabled to enable the `auto_blacklist` parameter. This parameter is not supported by the `dns-malformed` vector. This parameter is not supported by the `qdcount` vector.
blacklist_detection_seconds integer			Detection, in seconds, before blacklisting occurs.
blacklist_duration integer			Duration, in seconds, that the blacklist will last.
detection_threshold_eps string			Lists how many packets per second the system must discover in traffic in order to detect this attack. aliases: rate_threshold
detection_threshold_percent string			Lists the threshold percent increase over time that the system must detect in traffic in order to detect this attack. The `tcp-half-open` vector does not support this parameter. aliases: rate_increase
mitigation_threshold_eps string			Specify the maximum number of this type of packet per second the system allows for a vector. The system drops packets once the traffic level exceeds the rate limit. aliases: rate_limit
name string		Choices: ext-hdr-too-large hop-cnt-low host-unreachable icmp-frag icmpv4-flood icmpv6-flood ip-frag-flood ip-low-ttl ip-opt-frames ipv6-frag-flood opt-present-with-illegal-len sweep tcp-bad-urg tcp-half-open tcp-opt-overruns-tcp-hdr tcp-psh-flood tcp-rst-flood tcp-syn-flood tcp-syn-oversize tcp-synack-flood tcp-window-size tidcmp too-many-ext-hdrs udp-flood unk-tcp-opt-type a aaaa any axfr cname dns-malformed ixfr mx ns other ptr qdcount soa srv txt ack bye cancel invite message notify options other prack publish register sip-malformed subscribe uri-limit	Specifies the name of the vector to modify.

partition string		Default: "Common"	Device partition to manage resources on.
password string / required			The password for the user account used to connect to the BIG-IP. You may omit this option by setting the environment variable `F5_PASSWORD`. aliases: pass, pwd
per_source_ip_detection_threshold string			Specifies the number of packets per second to identify an IP address as a bad actor.
per_source_ip_mitigation_threshold string			Specifies the rate limit applied to a source IP that is identified as a bad actor.
profile string / required			Specifies the name of the profile to manage vectors in. The name `device-config` is reserved for use by this module. Vectors can be managed in either DoS Profiles, or Device Configuration. By specifying a profile of 'device-config', this module will specifically tailor configuration of the provided vectors to the Device Configuration.
provider dictionary added in 2.5			A dict object containing connection details.
	password string / required		The password for the user account used to connect to the BIG-IP. You may omit this option by setting the environment variable `F5_PASSWORD`. aliases: pass, pwd

	server_port integer	Default: 443	The BIG-IP server port. You may omit this option by setting the environment variable `F5_SERVER_PORT`.
	ssh_keyfile path		Specifies the SSH keyfile to use to authenticate the connection to the remote device. This argument is only used for cli transports. You may omit this option by setting the environment variable `ANSIBLE_NET_SSH_KEYFILE`.
	timeout integer	Default: 10	Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error.
	transport string	Choices: cli rest ←	Configures the transport connection to use when connecting to the remote device.
	user string / required		The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You may omit this option by setting the environment variable `F5_USER`.

server string / required			The BIG-IP host. You may omit this option by setting the environment variable `F5_SERVER`.
server_port integer added in 2.2		Default: 443	The BIG-IP server port. You may omit this option by setting the environment variable `F5_SERVER_PORT`.
simulate_auto_threshold boolean		Choices: no yes	Specifies that results of the current automatic thresholds are logged, though manual thresholds are enforced, and no action is taken on automatic thresholds. The `sweep` vector does not support this parameter.
state string / required		Choices: mitigate detect-only learn-only disabled	When `state` is `mitigate`, ensures that the vector enforces limits and thresholds. When `state` is `detect-only`, ensures that the vector does not enforce limits and thresholds (rate limiting, dopping, etc), but is still tracked in logs and statistics. When `state` is `disabled`, ensures that the vector does not enforce limits and thresholds, but is still tracked in logs and statistics. When `state` is `learn-only`, ensures that the vector does not "detect" any attacks. Only learning and stat collecting is performed.
threshold_mode string		Choices: manual stress-based-mitigation fully-automatic	The `dns-malformed` vector does not support `fully-automatic`, or `stress-based-mitigation` for this parameter. The `qdcount` vector does not support `fully-automatic`, or `stress-based-mitigation` for this parameter. The `sip-malformed` vector does not support `fully-automatic`, or `stress-based-mitigation` for this parameter.
user string / required			The username to connect to the BIG-IP with. This user must have administrative privileges on the device. You may omit this option by setting the environment variable `F5_USER`.
validate_certs boolean added in 2.0		Choices: no yes ←	If `no`, SSL certificates are not validated. Use this only on personally controlled sites using self-signed certificates. You may omit this option by setting the environment variable `F5_VALIDATE_CERTS`.

Notes

Note

For more information on using Ansible to manage F5 Networks devices see https://www.ansible.com/integrations/networks/f5.
Requires BIG-IP software version >= 12.
The F5 modules only manipulate the running configuration of the F5 product. To ensure that BIG-IP specific configuration persists to disk, be sure to include at least one task that uses the bigip_config module to save the running configuration. Refer to the module’s documentation for the correct usage of the module to save your running configuration.
