Why Talk about Advanced Threat Protection
“New Studies Reveal Companies are Attacked an
Average of 17,000 Times a Year.”
“Companies like J.P. Morgan Plan to Double
Spending on Cyber security…”
“Cybercrime Will Remain a Growth Industry for the
Foreseeable Future.”
“The Reality of the Internet of Things is the
Creation of More Vulnerabilities.”
“43% of firms in the United States have experienced
a data breach in the past year.”

Hello. Today we are going to talk about advanced attacks and advanced threat protection from Fortinet. We’ll also go into some detail on FortiSandbox, a key element of Fortinet’s complete advanced threat protection solution.
The threat landscape just keeps escalating and these days there is a lot of scrutiny over IT security because a successful data breach can be headline news. Certainly we’ve seen many very high profile companies and brands in the news with massive data breaches.
The risk environment has made a lot of organizations start to pay more attention to their security measures.
Viruses and hackers are not new, so what’s changed?
There are many more different types of devices attacked to the network than ever before. And this Internet of Things includes many devices that do not have the ability to maintain regular security updates and it includes many devices and applications made for consumer use that are now being used within the enterprise.
The cybercrime economy has matured and is a profitable industry that is more accessible than ever to black hat entrepreneurs.
There is much higher awareness of the risk due to laws requiring public disclosure of a breach and the subsequent press coverage some breaches get.
Hackers are getting even more sophisticated in how they orchestrate attacks in order to get around existing security coverage.
You may have any number of excellent security technologies in place already in your organization – things such as firewalls, VPNs, authentication, antivirus, web filtering, IPS, and antispam. This is good and these solutions will prevent a lot of threats from ever impacting your organization. However, nothing is 100% and sometimes advanced attacks will find a way to get through these prevention techniques. You need to be ready to deal with these types of advanced targeted attacks.
In recent breaches it took 229 days on average to detect an attack that’s gotten on the network if it has managed to slip past existing defenses. And in 67% of the time the victim organizations only learned about the breach from an external entity.
Clearly no organization wants to be part of this statistic.
The goal behind advanced threat detection is to prevent what attacks you can and then, accepting that some things will get through, to reduce the time to find and detect an attack. And once youv’e identified an attack, reduce the time it takes to investigate and analyze the threat. Finally, with this intelligence in hand you can more quickly remediate any impact on your organization.
So how does an advanced attack work? Here’s a snapshot of a typical kill chain for an advanced attack and the typical security technologies that are in play in order to block that attack and break the kill chain.
The number one, most popular method for initiating an advanced attack is to send a malicious email to the target. This email may have a malicious file attachment or a URL that connects to a malicious web site. You hope your anti-spam will stop this email from ever reaching an end user target. However there are ways to get around antispam and other email gateway security techniques. For example Bots may leverage legitimate (but compromised) IPs from which to send the email or they may use targeted spear phishing techniques and social engineering to get through filters and to entice an end users to click on a URL. They may encrypt a malicious attachment to hide it from AV scanning.
If an email with a malicious URL gets through and an end user clicks on that URL link, you hope your web filtering protection will stop the user from ever connecting to that malicious web site and in many cases this will work. However, some attackers use a fast flux approach, only using a site for a few days or a few hours – harvesting what they can before moving on to another URL.
If the end user connects with the malicious web site, that site will launch exploits at the user and you hope your Intrusion prevention will block the attack. However exploits can slip through by taking advantage of zero-day vulnerabilities, new variants, and encryption.
If an exploit gets through, you hope you will catch any malware it tries to deliver with your antivirus. And many times this will work but sometimes it doesn’t. Malware can use file compression, encryption, and new malware variants to get through an AV filter.
If that malware gets into the organization, it will try to proliferate and it will look for valuable data to collect. Eventually it will try to exfiltrate stolen data or simply go out to try to pull more threats into the organization and here’s where your application control and IP reputation controls may be able to identify and stop a connection to a command & control center. But if it doesn’t (maybe because the traffic was encrypted) your organization is breached.
Here’s how the addition of sandboxing changes the protection game in an enterprise.
It’s still a very good idea to have all those traditional preventative techniques in place. They are the fastest, most efficient way to prevent attacks from ever getting into your organization. However, by adding sandbox to back up these techniques you now have the chance to catch all those threats that can slip by because it is unknown by your preventative techniques such as antispam, IPS, AV, etc.
And once your sandbox has analyzed a threat, you get useful insights that can be used to mitigate the threat. Both by remediating any exposure to it you may have had and by using that new threat intelligence to improve the preventative technologies you have in place.
Flags suspicious (or high risk) objects within network traffic for more inspection
Runs objects in a secure virtual environment, analyzing system, site, communication and download activity
Provides a low, medium or high risk rating, leveraging packaged FortiGuard expertise
Uncovers threat lifecycle information for remediation and updated protection
Allows for information sharing with FortiGuard experts and global intelligence network
Fortinet’s FortiOS network security platform provides the foundation for the Advanced Threat Protection Framework, while the deep security expertise of its FortiGuard Labs pervades the framework:
Highlights
Top performance (Ixia, NSS Labs) firewall appliance platforms for access control of high performance networks
Top-rated (NSS Labs, Virus Bulletin, AV Comparatives), real-world threat prevention
Top-rated (NSS Labs), real-world threat detection- 99% effectiveness for breach detection
Leading security expertise (140+ zero-day discovers) to speed incident response and underpin the entire Framework
A broad range of partners who contribute to the continuous monitoring and improvement of security
You have your choice of platform for FortiSandbox. It is available as a physical or virtual appliance. There are two physical appliance options, the 1000D with 8 VMs and the 3000D with 28 VMs, and the highly flexible virtual appliance that scales from a few as 2 VMs up to 56 VMs.
For organization that may not want to manage an on-premise solution, there is the FortiSandbox Cloud service available as an integrated option on the FortiGate.
There are pros and cons for both the cloud and appliance options.
FortiSandbox Cloud may easier to add to an existing FortiGate installation. It can process an unlimited number of files/hour but because it is a cloud service it may introduce some latency. The cloud service is only available as an integrated solution with FortiGate.
FortiSandbox Appliances may deliver results faster and they don’t send files to the cloud for analysis but they also require some additional hardware management and have limits on the number of files they can process per hour. Appliances can be deployed as standalone solutions, in a lab for on-demand analysis or as an integrated solution with FortiGate.
Fortinet believes it benefits customers to give them the flexibility to choose the platform they want.
However, sandboxing is resource and time intensive. It takes time to let a file run so you can analyze its behavior.
Fortinet’s FortiSandbox solution is architected to optimize both security effectiveness and speed to results. It is not simply a sandbox, it uses a multi step approach to evaluate and analyze objects, starting with the most efficient technologies and stepping up to more resource intensive approaches as needed.
FortiSandbox goes through 5 steps.
Step 1: objects are run though Fortinet’s top-rated AV engine. This AV prefilter uses a larger, more extended threat database from FortiGuard Labs in order to catch more variants and older variants of malware.
Step 2: FortiSandbox performs a cloud query to see if this file has been previously identified (in some systems this is referred to as a file reputation check)
Step 3: the code is put through a simulator and Fortinet’s patented Compact Pattern Recognition Language is used to analyze the code to see if any malicious or suspicious patterns can be identified
Steps 1 through 3 are typically performed in just a few seconds. On average these three steps are able to identify over 60% of threats.
Step 4: the code is placed in a full virtual sandbox environment and allowed to run. The behavior lifecycle of the code is observed and if the object is malicious, it will expose itself.
Step 5: The activity in the sandbox is analyzed to identify if it is malicious or suspicious and the activity is documented. The object is assigned a risk rating and is then reported out. New findings from this analysis can be shared with FortiGuard Labs in order to create new security updates in order to improve the extended FortiGuard security ecosystem.
Fortinet also participates in NSS Labs testing for NGFW and Breach Detection Systems. These are the results of the Breach Detection Systems industry tests in 2014. As you can see in the chart, Fortinet tested high for effectiveness and well for performance and value, detecting 99% of threats and delivering results in under 1 minute the majority of the time. The vertical axis shows the security effectiveness results from the test and the horizontal axis shows the performance/value results. Fortinet’s FortiSandbox fell into the upper right quadrant in results and thus earned a Recommended rating from NSS Labs.

By implementing an Advanced Threat Protection Framework the process of learning, remediating and improving security follows a natural flow.
In the Detection and Analysis phase the sandbox identifies suspicious threat activities such as privilege modification and file creation or deletion as well as known malicious behavior such as initiated network traffic or DNS queries. The sandbox can learn details from its analysis in form of file names, URLs, IP addresses and more that can be used in remediation and added to security updates.
With the details of a threat attack, including its source and destination from FortiSandbox, it is much easier to instigate immediate remediation activities such as blocking an email sender IP from sending more messages to employees, preventing communications with known command & control addresses, and to quarantine compromised devices within the network to prevent the spread of malware.
Finally, the threat information learned by the sandbox has multiple uses. Malicious IP addresses and URLs identified can be added to web filtering and IP reputation lists. File characteristics can be used to create new IPS rules and anti-malware signatures. All this feeds into security updates to improve the protection delivered by all the solutions in the framework.
In fact, organizations looking to take a coordinate approach to combating advanced threats benefit from NSS Labs Recommended components including:
FortiGate as NGFW and NGIPS in the data center and at the edge
FortiWeb in front of external-facing web servers that often serve as entry points to the network
FortiClient for Enterprise Endpoint Protection covering users on and off the network
FortiSandbox for continuous analysis of seemingly benign objects and sites to detect the most sophisticated attacks that might slip through your defenses.
