Extended-UTM-Log Enable Error

I received the following question through my consulting form:

Question: when configuring application list, setting the “extended-utm-log” the I got the following error:

burgfg01 (list) $ edit “RogersStandard”
new entry ‘RogersStandard’ added

set extended-utm-log enable
burgfg01 (RogersStandard) $ set extended-utm-log enable

command parse error before ‘extended-utm-log’
Command fail. Return code -61

Please advise.

Answer: Chances are the user is utilizing FortiOS 5.2 or later which no longer has the extended-utm-log enable feature.

Fortinet Acquires AccelOps

In case you guys didn’t know already Fortinet has bought, or acquired, or whatever we want to call it,AccelOps. Here is an excerpt from their blog post.

One of the biggest security challenges organizations face is being able to see enough of the network to identify today’s most advanced, multi-vector threats. Ideally, you need to be able to see across the distributed network, including cloud deployments and devices from multiple network and security vendors, correlate detected local activity with global threat intelligence and expected behaviors, and coordinate a response across the entire portfolio of installed security solutions.

This becomes increasingly challenging as networks continue to expand beyond the perimeter and embrace increasing numbers of devices and applications. As the network expands, the attack surface naturally expands with it. At the same time, new threats are targeting this distributed network architecture. Mobility, IoT, virtualization, big data, and the cloud aren’t only transforming businesses. They are being specifically targeted, which is a game changer for security as well. For example, it is estimated that by 2020 over 25% of attacks on enterprises will involve IoT.

A Wrap Up Of HITB Amsterdam 2016 Conference

23 May 2016 marked the first day of the annual security conference organized by Hack In the Box. As usual, the event took place in Amsterdam, Netherlands. This year I had the privilege to attend. HITB is one of the top-notch technical conferences, where elite security researchers from around the world gather to share their research. Not to mention that it is also a great place to hang out with these people to exchange ideas offstage. There were so many great talks in this conference. I am pleased to share a couple of talks here that I feel were particularly interesting.

One of my favorite, and most anticipated talks, was Go Speed Tracer: Guided Fuzzing presented by Richard Johnson. Richard is an expert in fuzzing technology, particularly emphasizing on how to optimize the performance of traditional fuzzers to make them scale extensively. Of course, traditional fuzzing methodologies, such as dump fuzzing, which use simple sample-based mutation still work in most cases. However, they are often limited to discovering minor security issues, and eventually lead to bottlenecking, an issue many security researchers come across when writing their own fuzzer. Feedback driven fuzzing is an evolutionary fuzzing methodology, made possible by the introduction of American Fuzzy Lop (AFL), an approach that is able to enhance the coverage of a fuzzer, thereby increasing the chances that the user can discover more security issues, or even uncover severe security vulnerabilities. After thoroughly studying various open source fuzzers like AFL, Richard shed some light in his presentation on how to customize your own, optimal performance guided fuzzer using existing binary instrumentation technologies like Pin, DynamoRIO, and DynInst. He also performed a couple of demos that showed the performance overhead between Pin and DynamoRIO, which showed that DynamoRIO seems to outperform Pin in term of binary code instrumentation. Unfortunately, he wasn’t able to show the demo of AFL with full support for Windows binary, along with hardware tracing using Intel Processor Tracer via Windows driver, as the prototype has not been completed yet. Nevertheless, it was an inspirational talk for researchers who are interested in developing their own fuzzer.

FortiClient Monitoring and Quarantine

FortiClient Monitoring and Quarantine

FortiClient monitoring and quarantine is currently only supported by FortiClient 5.4 for Windows.

FortiSandbox uses a single signature to identify tens of thousands of variations of viral code. A FortiSandbox can send frequent, dynamic signature updates to a FortiGate and FortiClient, which allows files to be blocked before they are sent to the FortiSandbox.

With FortiSandbox, FortiClient, and FortiGate integration, you can configure a FortiGate to send files to FortiSandbox for scanning.

When FortiSandbox determines that a file is infected, it will notify the FortiGate of this event. Then, from

FortiView, the administrator can take action to quarantine the endpoint which downloaded the infected file. FortiGate administrators can quarantine endpoints from FortiView.

To support this, the FortiClient now supports host-level quarantine, which cuts off other network traffic from the endpoint directly, preventing it from infecting or scanning the local network.

When a device is under quarantine, FortiClient cannot be shutdown or uninstalled. A user is also unable to unregister from the FortiGate that quarantined them, or register to another FortiGate unit.

Alternately, FortiGate can release the file to the client before receiving the FortiSandbox scan results, and then have FortiClient quarantine the device when the scan results are available if required.

Pushing signatures to AntiVirus

Pushing signatures to AntiVirus

When a FortiSandbox discovers a malicious file, it can create a signature that is sent to the FortiGate, to supplement the AntiVirus signature database. This signature can be used to block that file from entering the network again, and to prevent duplicates of the file being sent to the FortiSandbox in the future. This feature is enabled in an AntiVirus profile.

CLI Syntax

config antivirus profile edit “default”

set ftgd-analytics {everything | suspicious}

set analytics-db {enable | disable}


Files blocked by a FortiSandbox signature can be viewed and filtered for in the FortiSandbox dashboard.

In FortiOS 5.4 Beta 2, the URL feature is only available for proxy-based Web Filter profiles.

Information on the current database for both malware signatures and blocked URLs can be found by going to

System > External Security Devices.


FortiSandbox Integration

FortiSandbox Integration

The following improvements have been made to how sandboxing, using either a FortiSandbox Appliance or

FortiCloud Sandboxing, integrates with a FortiGate unit.

See the Cookbook recipe Sandboxing with FortiSandbox and FortiClient.

Connecting to a FortiSandbox

1. Go to System > External Security Devices and select Enable Sandbox Inspection.

2. You can either select FortiSandbox Appliance or FortiSandbox Cloud.

3. If you select FortiSandbox Appliance, add the Server IP address.

4. Select Test Connectivity to verify that you can connect to FortiSandbox.

5. Then edit an AntiVirus profile by going to Security Profiles > AntiVirus and selecting Send Filter to

FortiSandbox Appliance for Inspection.

6. You can also select to send Suspicious Files, Executable files or all supported files.

7. Select Use FortiSandbox Database to add signatures for suspicious files found by FortiSandbox to your

FortiGate antivirus signature database.

8. Then select this Antivirus profile in a firewall policy to send files in traffic accepted by the firewall policy to


9. You can also go to Security Profiles > Web Filter and select Block malicious URLs discovered by


Pushing malicious URLs to Web Filtering

The malicious URL database contains all malicious URLs active in the last month. The FortiSandbox can add the URLs where any malicious files originated to a URL filter, to block these files from being downloaded again from that URL.

This feature is enabled in a Web Filter profile under Security Profiles > Web Filter > Block malicious URLs discovered by FortiSandbox.

CLI Syntax

config webfilter profile edit <profile>

config web

set blacklist [enable | disable]

… end

Files blocked by a FortiSandbox signature can be viewed and filtered for in the FortiSandbox dashboard. Information on the current database for both malware signatures and blocked URLs can be found by going to System > External Security Devices.

FortiSandbox Dashboard in FortiView

The FortiSandbox dashboard is available from FortiView > FortiSandbox. The dashboard shows all samples submitted for sandboxing. Information on the dashboard can be filtered by checksum, file name, result, source, status, and user name. Each entry also offers a drilldown view to show more details about a particular sample.

Web Application Firewall

Web Application Firewall

Go to Security Profiles > Web Application Firewall. From here you can customize the default Web Application Firewall profile, or create new profiles, to protect against a variety of web-based threats. Web Application Firewall profiles can be created with a variety of options (Signatures and Constraints), similar to other security profiles.

You can set the Web Application Firewall to use an External Security Device, such as FortiWeb, by setting

Inspection Device to External.

Web Application Firewall

Selecting External in the Web Application Firewall profile adds the following configuration to the CLI:

config waf profile edit default

set external enable end

You must add the Web Application Firewall profile to a firewall policy in order for that traffic to be offloaded to the

External Security Device for processing.

If your FortiGate or VDOM Inspection mode is set to flow-based you must use the CLI to set a Web Application Firewall profile to external mode and add the Web Applic- ation Firewall profile to a firewall policy.




To be able to offload Anti-Spam processing to a FortiMail device you should.

1. Go to System > Feature Select and turn on AntiSpam Filter.

2. Go to System > External Security Devices, enable SMTP Service – FortiMail and add the IP address of your FortiMail device.

3. Go to Security Profiles > Anti-Spam and edit an Anti-Spam profile and set Inspection Device to External.

4. Go to Policy & Objects > IPv4 Policy, add or edit a Firewall policy, enable AntiSpam and select the profile for which you set Inspection Device to External.

When you add this Anti-Spam profile to a firewall policy, email traffic accepted by the policy is offloaded to the

FortiMail device for processing.

If your FortiGate or VDOM inspection mode is set to flow-based you must use the CLI to set an Anti-Spam profile to external mode and add the Anti-Spam profile to a fire- wall policy.

Enabling FortiMail on the External Security Devices page adds the following configuration to the CLI:

config system wccp set service-id 52

set router-id (the IP address of the FortiGate interface that communicates with the FortiMail)

set group address

set server-list (the IP address of the FortiMail)

set authentication disable set forward-method GRE

set return-method GRE

set assignment-method HASH



Selecting External in the Anti-Spam profile adds the following configuration to the CLI:

config spamfilter profile edit default

set external enable end
