Action Detail

From "Policy Settings" in the navigation menu, you can view and configure security policies for devices and the UnAuth Group.
You can also view and add actions from this menu.

#### About Security Policies

Each security policy consists of the following attributes.

- Network
  A tagged VLAN to which devices are assigned to.
  A registered device is assigned to the VLAN subnet specified by a Network attribute of the matched security policy when the device gets connected to an OpenFlow Switch or an AMF Member (Edge Node).
  If the device's security policy does not specify a Network, it is assigned to the untagged VLAN (a subnet without VLAN) on the OpenFlow Switch or the VLAN configured on the Edge Node.
  AMF Security achieved this VLAN assignment by instructing the switch to add VLAN tags with the specified VLAN ID when the switch forwards packets from the device out of their upstream port.

  > Note

  > > If a device can access untagged VLAN, depending on the switch settings, the device may be able to connect to devices on the control plane.

  > Note

  > > If the device with the registered MAC Address is connected to the TQ of AMF Application Proxy, it depends on the TQ setting. Refer to Quick Tour / What is AMF Security > TQ's AMF Application Proxy / Behavior when using TQ dynamic VLAN.

- Location
  A physical location where a device can access the network.
  If you specify a Location for a device, the device can access the network only from the OpenFlow Switches or Edge Nodes in the location.
  If you do not specify a Location, a device can access the network from any switches.
- Schedule
  A time period during a device can access the network (Start Date / Time, and End Date / Time).
  If you specify a Schedule for a device, the device can access the network only when the schedule is effective. If you do not specify a schedule, a device can always access the network.
  A quarantined device may be able to communicate after the configured End Date / Time of a Schedule because a flow lifetime for the Quarantine VLAN precedes the Schedule End Date / Time. The value of "Flow Lifetime" on the System Settings > OpenFlow Settings page is used for this timeout.

When a device has multiple security policies attached, a matching policy with the lowest priority value is used.
When a security policy has a specific schedule, AMF Security determines what action to take based on the date and time when a device gets connected.
This section describes an example in which the security policies shown in the following table:

Table 1: A security policy for a registered device
Priority | Schedule Start Date / Time | Schedule End Date / Time | Network
--- | --- | --- | ---
10 | 20XX-04-01 00:00:00 | 20XX-09-30 23:59:59 | VLAN10
20 | 20XX-01-01 00:00:00 | 20XX-12-31 23:59:59 | VLAN20

When a device gets connected to a network at "20XX-03-30 10:00:00", the device is assigned to the VLAN20 because it matches the security policy with the priority value of 20.
As the time goes on, the device is re-assigned to the VLAN10 at "20XX-04-01 00:00:00" because the time suddenly goes into the valid range of the security policy with the higher priority value of 10.

#### About the start date and time and end date and time of the schedule

The Start Date / Time and End Date / Time to be set are the date and time of the timezone currently set on the System Settings /Date > Time Settings page.
If the timezone is changed after registering the schedule, the Start Date / Time and End Date / Time of the schedule is changed according to the changed timezone.
As an example, if you register the schedule with the timezone set to "UTC" and then change the timezone to "Asia/Tokyo", the Start Date / Time of the schedule is "UTC + 9 hours".

Table 2: Set the following with the timezone set to "UTC"
Schedule Start Date / Time | Schedule End Date / Time
--- | ---
20XX-04-01 08:00:00 | 20XX-09-30 23:59:59

Table 3: Timezone changed from "UTC" to "Asia / Tokyo"
Schedule Start Date / Time | Schedule End Date / Time
--- | ---
20XX-04-01 17:00:00 | 20XX-10-01 08:59:59

Therefore, when performing operations related to schedule settings such as the following, make sure that the timezone used is set in advance.

- Add / update schedule in Policy Settings
- Export / Import Authentication Data on the System Settings > System Information page
- Registration of Authentication Data by AMF Security linked application (API)

> Note

> > The system settings exported on the System Settings > System Information page include timezone settings. The default timezone for AMF Security is UTC. If you want to import the backed up System Settings and Authentication Data after initializing AMF Security or performing a new installation, Import "System Settings" → Restart AMF Security → Import "Authentication Data".

### Add Network

This page lets you create a new network with its VLAN ID.
Networks are used for specifying which VLAN to put an allowed device in.
AMF Security achieves this by telling switches to add appropriate VLAN tags to the packet originating from the allowed devices.

Action
OpenFlow/TQ Action | An action of the OpenFlow/TQ's AMF Application Proxy to be applied to the target device. ・Pass(Permit): Permit traffic from the device. ・Quarantine: Move the device to the quarantine network. ・Drop(Block): Block traffic from the device. ・Log-Only: AMF Security does not notify you of the action and does not control the communication of the device. Output only the log of the applicable device.
Pass/Quarantine VLAN ID | A VLAN ID on which the device is allowed to transmit packets. This item is displayed when the OpenFlow/TQ Action is Pass(Permit) and Quarantine.
AMF Action | Contents of the action when instructing the communication interruption of the corresponding device using AW+ AMF Application Proxy. ・AMF Dependency: AMF Security does not specify an action and lets AMF devices determine its action. ・Quarantine: Move the device to the quarantine VLAN. ・Drop Packets: Block traffics from the device at the layer two (MAC) level. ・Link-Down: Shutdown the port where the device is connected. ・IP-Filter: Block traffics from the device at the layer 3 (IP) level. ・Log-Only: AMF Security does not specify an action and records the device information.

> Note

> > The behavior of the "Quarantine" action depends on the firmware version of your AlliedWare Plus device (Edge Nodes).
> > ・Version 5.5.0-2.x or later when using multiple dynamic VLANs with port authentication (including AMF Application Proxy Whitelist) and AMF Application Proxy Blacklist: Move only the MAC address of the affected device to the quarantine VLAN
> > ・Otherwise: Move the port to which the affected device is connected to the quarantine VLAN

> Note

> > Prior to version 5.5.0-2.x, dynamic VLANs cannot be used when using quarantine action and port authentication (including AMF Application Proxy Whitelist) on the same port.
