Configure Static File Reputation Host or an Alternate File Reputation Cloud Server Pool on ESA

Introduction

This document describes how to configure a Cisco Email Security Appliance (ESA) to communicate and use a static host or an alternative reputation cloud server pool for File Reputation with the use of Advanced Malware Protection (AMP).

Background Information

A File Reputation query is the first of two layers for AMP on the ESA.  File Reputation captures a fingerprint of each file as it traverses the ESA and sends it to AMP’s cloud-based intelligence network for a reputation verdict. Given these results, ESA administrators can automatically block malicious files and apply administrator-defined policies.  The File Reputation cloud service is hosted on Amazon Web Services (AWS). When you perform DNS queries against the hostname(s) described in this document, you will see ".amazonaws.com" listed.

The second layer of AMP on the ESA is File Analysis.  That is not covered in this document.

SSL communication for File Reputation traffic uses port 32137 by default. At the time of the configuration of the service, port 443 might be used as an alternative. Consult the ESA User Guide, "File Reputation Filtering and File Analysis" section for complete details. ESA and Network administrators might wish to verify connectivity to the pool for IP address(es), IP location, and also port communication (32137 vs. 443) before they proceed with the configuration.

Default AMERICAS(Legacy) reputation cloud server pool (cloud-sa.amp.sourcefire.com)

Once File Reputation is licensed, enabled, and configured on an ESA, by default it will be set for this reputation cloud server pool:

• AMERICAS(Legacy) (cloud-sa.amp.sourcefire.com)

The hostname "cloud-sa.amp.sourcefire.com" is a DNS Canonical Name record (CNAME).  A CNAME is a type of resource record in DNS used to specify that a domain name is an alias for another domain, which is the "canonical" domain. Associated hostnames in the pool tied to this CNAME might be similar to:

• ec2-107-22-180-78.compute-1.amazonaws.com (107.22.180.78)
• ec2-54-225-142-100.compute-1.amazonaws.com (54.225.142.100)
• ec2-23-21-208-4.compute-1.amazonaws.com (23.21.208.4)
• ec2-54-83-195-228.compute-1.amazonaws.com (54.83.195.228)

There are two additional file reputation servers choices that may be selected:

• AMERICAS (cloud-sa.amp.cisco.com)
• EUROPE (cloud-sa.eu.amp.cisco.com)

Both of these servers are covered in the "Static File Reputation server hostnames (.cisco.com)" section of this document.

You might verify the hosts that are associated to the AMERICAS cloud-sa-amp.sourcefire.com CNAME from your network at anytime when you run this dig or nslookup query:

╰─$ dig cloud-sa.amp.sourcefire.com +short
cloud-sa-589592150.us-east-1.elb.amazonaws.com.
107.22.180.78
54.225.208.214
23.21.208.4
54.83.195.228

╰─$ nslookup cloud-sa.amp.sourcefire.com
Server: 208.67.222.222
Address: 208.67.222.222#53

Non-authoritative answer:
cloud-sa.amp.sourcefire.com canonical name = cloud-sa-589592150.us-east-1.elb.amazonaws.com.
Name: cloud-sa-589592150.us-east-1.elb.amazonaws.com
Address: 54.225.208.214
Name: cloud-sa-589592150.us-east-1.elb.amazonaws.com
Address: 54.83.195.228
Name: cloud-sa-589592150.us-east-1.elb.amazonaws.com
Address: 107.22.180.78
Name: cloud-sa-589592150.us-east-1.elb.amazonaws.com
Address: 23.21.208.4

Note: These hosts are NOT static and it is recommended to NOT restrict ESA File Reputation traffic based to only these hosts. The results of your query might vary, as the hosts in the pool will change without notice.

You can verify the IP geographical location from this 3rd party tool:

• http://geoiplookup.net/ip/54.83.195.228

Static File Reputation server hostnames (.cisco.com)

Cisco began to provide ".cisco.com" based hostnames for the File Reputation service for AMP in 2016.  There are static hostnames and IP addresses available for File Reputation from this:

• cloud-sa.amp.cisco.com (North America - USA)
• cloud-sa.eu.amp.cisco.com (Europe – Republic of Ireland)
• cloud-sa.apjc.amp.cisco.com (Asia Pacific – Japan)

You might verify the hosts and associated IP addresses from your network and run a dig or nslookup query:

North America (US):

╰─$ dig cloud-sa.amp.cisco.com +short
52.21.117.50

Europe (Republic of Ireland):

╰─$ nslookup cloud-sa.eu.amp.cisco.com
Server: 208.67.222.222
Address: 208.67.222.222#53

Non-authoritative answer:
Name: cloud-sa.eu.amp.cisco.com
Address: 52.30.124.82

Asia Pacific (Japan):

 ╰─$ dig cloud-sa.apjc.amp.cisco.com +short
52.69.39.127

You can verify the IP geographical location from this 3rd party tool:

• http://geoiplookup.net/ip/52.21.117.50

• http://geoiplookup.net/ip/52.30.124.82

• http://geoiplookup.net/ip/52.69.39.127

At this time, there are no plans to decommission the ".sourcefire.com" hostnames.

Alternative EUROPE reputation cloud server pool (cloud-sa.eu.amp.sourcefire.com)

For European Union (EU) based customers that are required to send specific traffic to EU-based only servers and data centers, administrators can configure the ESA to point to either the EU static host or to the EU reputation cloud server pool:

• cloud-sa-eu.amp.cisco.com
• cloud-sa.eu.amp.sourcefire.com

Like the default hostname "cloud-sa.amp.sourcefire.com", the hostname "cloud-sa.eu.amp.sourcefire.com" is also a CNAME. Associated hostnames in the pool tied to this CNAME might be similar to:

• ec2-54-217-245-97.eu-west-1.compute.amazonaws.com (54.217.245.97)
• ec2-54-247-186-153.eu-west-1.compute.amazonaws.com (54.247.186.153)
• ec2-176-34-122-245.eu-west-1.compute.amazonaws.com (176.34.122.245) 

You might verify the hosts that are associated to the EUROPEAN cloud-sa.eu.amp.sourcefire.com CNAME from your network and run a dig or nslookup query::

╰─$ dig cloud-sa.eu.amp.sourcefire.com +short
cloud-sa-162723281.eu-west-1.elb.amazonaws.com.
54.217.245.97

Configure Static File Reputation Host or an Alternate File Reputation Cloud Server Pool on ESA

File Reputation can be configured from either the GUI or CLI on the ESA. The configuration steps listed in this document will demonstrate the CLI configuration. However, the same steps and information can be applied via the GUI (Security Services > File Reputation and Analysis > Edit Global Settings... > Advanced Settings for File Reputation).

AsyncOS 10.x and Newer

New features of AsyncOS 10.x allow the ESA to be configured to use a private reputation cloud (On-Premises File Reputation Server) or cloud-based file reputation server. With this change, AMP configuration no longer prompts for the hostname with the "Enter reputation cloud server pool" step. You must choose to setup the additional file reputation server as a private reputation cloud and provide the public key for that hostname.

For 10.0.x and newer, when you configure an alternative AMP reputation server, you might be required to enter a public key associated to that hostname.

All of the AMP reputation servers use the same public key:

-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEchIap1VqPuGibM2n3wjfhqQZdzC9
WI1Z7QZ2Q7VesLe+A53TxYujeo7fCDKJEQKrPjU6kI36PSZusObr9Cur/g==
-----END PUBLIC KEY-----

This example will help you set up the alternative file reputation server to cloud-sa.eu.amp.sourcefirce.com:

On-Premises File Reputation Server (FireAMP Private Cloud)

Use of an on-premises file reputation server, also known as a FireAMP Private Cloud, was introduced that starts with AsyncOS 10.x for Email Security.

If you have deployed a Cisco AMP Virtual Private Cloud appliance on your network, you can now query the file reputation of message attachments without sending them to the public reputation cloud. To configure your appliance to use an on-premises file reputation server, see the “File Reputation Filtering and File Analysis” chapter in the ESA User Guide or online help.

  

Verify

Use this section in order to confirm that your configuration works properly.

In order to see File Reputation traffic passing to the configured static host or reputation cloud server pool, perform a packet capture from the ESA with specified filter to capture port 32137 or port 443 traffic.

For this example, use the cloud-sa.eu.amp.sourcefire.com cloud server pool and SSL communication with the use of port 443...

This is logged to the ESA in the AMP logs:

You see that the traffic communicates over port 443. From our ESA (my11esa.local), it communicates to the hostname ec2-176-34-122-245.eu-west-1.compute.amazonaws.com. This hostname is tied to the IP address 176.34.122.245:

╰─$ dig ec2-176-34-122-245.eu-west-1.compute.amazonaws.com +short
176.34.122.245

The IP address of 176.34.122.245 is a pool member of the CNAME for cloud-sa.eu.amp.sourcefire.com:

╰─$ dig cloud-sa.eu.amp.sourcefire.com +short
cloud-sa-162723281.eu-west-1.elb.amazonaws.com.
54.217.245.200
54.247.186.153
176.34.122.245

For this example, communication was directed and accepted by the configured reputation cloud server pool, cloud-sa.eu.amp.sourcefire.com.

Troubleshoot

This section provides information you can use in order  to troubleshoot your configuration.

Use Telnet to Test Connectivity

In order to verify port level connectivity to the File Reputation cloud, use the hostname for the configured reputation cloud server pool, and test with telnet to port 32137, or port 443, as configured.

You can test telnet to the direct IP or hostnames behind the CNAME for the reputation cloud server pool with the same telnet test method, with the use of port 32137 or port 443. If you are not able to successfully telnet to the hostname and port, you might need to check network connectivity and firewall settings external to the ESA.

Verification of telnet sucess to an on-premise file reputation server will be done by the same process as shown.

Input of the Public Key

When you enter the public key on an ESA running AsyncOS 10.x and newer, assure that you were successful in pasting or loading the public key. Any errors in the public key will be displayed to the configuration output:

Do you want to input new public key? [N]> y

Paste the public key followed by a . on a new line
-----BEGIN PUBLIC KEY-----
MEAwEAYHKoZIzj0CAQYFK4EEAAEDLAAEAIHPMkqCH057gxeQK6aUKqmpqk+1AW0u
vxOkpuI+gtfLICRijTx3Vh45
-----END PUBLIC KEY-----
.
Failed to save public key

If you receive an error, retry the configuration. For persistent errors, contact Cisco Support.

Review AMP logs

When you view the AMP log on the ESA, ensure that you see "file reputation query from Cloud" specified at the time of file reputation query:

Sun Mar 26 11:28:13 2017 Info: File reputation query initiating. File Name = 'billing_fax_271934.doc', MID = 458, File Size = 143872 bytes, File Type = application/msword
Sun Mar 26 11:28:14 2017 Info: Response received for file reputation query from Cloud. File Name = 'billing_fax_271934.doc', MID = 458, Disposition = MALICIOUS, Malware = W32.50944E2888-100.SBX.TG, Reputation Score = 0, sha256 = 50944e2888b551f41f3de2fc76b4b57cb3cd28e718c9265c43128568916fe70f, upload_action = 2

If you see this, the query pulled the response from local ESA cache and NOT from the configured reputation cloud server pool :

Sun Mar 26 11:30:18 2017 Info: File reputation query initiating. File Name = 'billing_fax_271934.doc', MID = 459, File Size = 143872 bytes, File Type = application/msword

Additional Errors and Alerts

An ESA administrator might receive this notice. If this is received, re-step through the configuration and verification process.

The Warning message is:
