Anonymity Networks and Groups

An anonymity network is used to hide one’s network identity, and is typically used by malware to hide its originating IP address. Enterprise network traffic should not be originating from or destined to Anonymity network.

When FortiSIEM discovers traffic destined to or originating from anonymity networks, it triggers these rules:

Inbound Traffic from Tor Network

Outbound Traffic to Tor Network

Inbound Traffic from Open Proxies

Outbound Traffic to Open Proxies

Adding an Anonymity Network

  1. Log into your Supervisor node.
  2. Go to CMDB > Anonymity Networks.
  3. Create a group to add the new network to if you are not adding it to an existing group.
  4. Select the group where you want to add the anonymity network.
  5. Click New.
  6. Enter IP, Port, and Country information about the anonymity network.
  7. Click the Calendar icon to enter the date you created or updated this entry.

Setting Up an External Data Source for Anonymity Networks

This topic describes how to import anonymity networks information into FortiSIEM from external threat feed websites. Anonymity networks are used by malware to hide their own identity. Two prominent examples of anonymity networks are Open Proxies and TOR Nodes.

Prerequisites

Procedure

Websites with built in support

Custom websites – CSV data – one-time manual import

Custom websites – CSV data – programmatic import

New Websites – non-CSV data – programmatic import

Prerequisites

Before proceeding gather the following information about a threat feed web site.

The website URL

Credentials required to access the website (optional)

If the website is not supported by FortiSIEM, you may need to understand the format of the data returned by the URL. if the data is in the comma separated value format (the separator need not be a comma but could be any separator, then a simple integration is possible.

If the data is any other format, e.g. XML, then some code needs to be written for integration using the FortiSIEM provided framework

FortiSIEM Categorization of Devices and Applications

Leave a reply
Categorization of Devices and Applications

FortiSIEM uses four methods to identify and categorize devices and applications in the CMDB.

From Discovery – Network Devices

When FortiSIEM discovers a device, it looks for keywords in the SNMP sysDescr attribute and also probes for the SNMP sysObjectID attribut e. Internal tables are then used to map a discovered device to one or more CMDB device groups based on these attributes.

Keywords from the sysDescr attribute are matched against the system table Device Vendor and Model

Keywords from the sysObjectID attribute are matched against the system table Device Vendor and Model

Matches from the Device Vendor and Model table are then matched against the ApprovedDeviceVendor.csv table that is used to create the categories in the CMDB Devices/Applications.

From Discovery – Applications

FortiSIEM discovers applications by discovering the processes that are running on a server. The table AppMapping.csv maps process names to Applications, Application Groups, and application folders in the CMDB.

From Logs

FortiSIEM includes a large number of log parsers, each of of which is associated with a Device Vendor/Model and Application Vendor/Model. When the log is parsed by FortiSIEM, the Device/Application/Vendor information is matched against the table ApprovedDeviceVendor.csv, which then assigns the application or device to the appropriate CMDB Device/Application folder.

Special Cases

There are some special cases that cannot be categorized using discovery or log information. An example is Microsoft Active Directory. It is an application, but there is no explicit process for i.t as it is part of the kernel or big system service. In this case, specific logs are used: Windows Security logs 672, 673 to detect Microsoft Domain Controller 2000, 2003, and  Windows Security logs 4768, 4769 to detect Microsoft Windows Domain Controller 2008, 2012.

Examples

Categorizing a Cisco IOS Router/Switch

This is an example of categorizing a device using discovery. In this case, the Cisco IOS substring in the SNMP sysDescr attribute is used to detect a Cisco IOS device,

Then this entry in ApprovedDeviceVendor.csv maps the Device Vendor/Model Cisco IOS to the Router/Switch category in the CMDB. PH_ SYS_DEVICE_ROUTER_SWITCH is the internal ID of the category.

Categorizing Fortinet Firewalls

This is also an example of categorizing a device by discovery. In this case, the SNMPv2-SMI::enterprises.12356 substring in the SNMP sy sObjectId attribute is used to detect a Fortinet Firewall device.

Then this entry in the ApprovedDeviceVendor.csv table maps the Device Vendor/Model Fortinet FortiOS to the Firewall and Network IOS categories in the CMDB, since Fortinet is a UTM device. PH_SYS_DEVICE_FIREWALL and PH_SYS_DEVICE_NETWORK_IPS are the internal IDs of the categories.

Categorizing Microsoft IIS

This is an example of categorizing an application based on a running process. In this case, SNMP discovers a process svchost.exe with the

This entry in the AppMapping.csv table is then used to map the process name svchost.exe with the path name -k iissvcs to a Microsoft IIS application.

Categorizing Cisco ASA

This is an example of categorizing a device based on logs. The Cisco ASA parser has has a Device Vendor/Model associated with it, and when a log from the Cisco ASA device is parsed by FortiSIEM, this entry in ApprovedDeviceVendor.csv maps the Device Vendor/Model Cisco ASA to the Firewall and VPN Gateway categories in the CMDB. PH_SYS_DEVICE_FIREWALL and PH_SYS_DEVICE_VPN_GATEWAY are the internal IDs of these categories.

Categorizing Microsoft IIS

This is an example of categorizing an application based on logs. The Microsoft IIS (via Snare) parser has a Device Vendor/Model associated with it, and when a log from Microsoft IIS is processed by FortiSIEM, this entry in ApprovedDeviceVendor.csv maps the Device Vendor/Model Mi crosoft to the Windows Server and Web Server categories in the CMDB. PH_SYS_DEVICE_WINDOWS_SERVER and PH_SYS_APP_WEB_SER

VER are the internal IDs of these categories.
