Configuring Attack Detection Exemption; Applying An Attack Defense Policy To The Device - HPE Moonshot 45Gc Security Configuration Manual

Configuring an HTTP flood attack defense policy
Step
1. Enter system view.
2. Enter attack defense policy
view.
3. Enable global HTTP flood
attack detection.
4. Set the global trigger
threshold for HTTP flood
attack prevention.
5. (Optional.) Specify the
global ports to be protected
against HTTP flood attacks.
6. Specify global actions
against HTTP flood attacks.
7. Configure IP
address-specific HTTP
flood attack detection.

Configuring attack detection exemption

The attack defense policy uses the ACL to identify exempted packets. The policy does not check the
packets permitted by the ACL. You can configure the ACL to identify packets from trusted hosts. The
exemption feature reduces the false alarm rate and improves packet processing efficiency.
To configure attack detection exemption:
Step
1. Enter system view.
2. Enter attack defense policy
view.
3. Configure attack detection
exemption.

Applying an attack defense policy to the device

An attack defense policy applied to the device itself detects packets destined for the device and
prevents attacks targeted at the device.
A switch uses hardware to implement packet forwarding and uses software to process packets if the
packets are destined for the switch. The software does not provide any attack defense features, so
you must apply an attack defense policy to the switch to prevent attacks aimed at the switch.
To apply an attack defense policy to the device:
Command
system-view
attack-defense policy
policy-name
http-flood detect non-specific
http-flood threshold

http-flood port port-list
http-flood action { drop |

http-flood detect { ip ip-address
| ipv6 ipv6-address }
[ vpn-instance

port-list ] [ threshold

Command
