The antivirus scanning function includes various modules and engines that perform separate tasks. P r o xy — b ase d antivirus scanning order. The following figure illustrates the antivirus scanning order when using proxy-based scanning. The uncompsizelimit check is to determine if the file can be buffered for file type and antivirus scanning.

If the file is too large for the buffer, it is allowed to pass without being scanned. For more information, see the config antivirus service command. The antivirus scan includes scanning for viruses, as well as for grayware and heuristics if they are enabled. File filtering includes file pattern and file type scans which are applied at different stages in the antivirus process.

A n t i v i r u s scanning order when using the normal, extended, or extreme database. If a file fails any of the tasks of the antivirus scan, no further scans are performed. For example, if the file fakefile. EXE is recognized as a blocked file pattern, the FortiGate unit will send the end user a replacement message, and delete or quarantine the file. The unit will not perform virus scan, grayware, heuristics, and file type scans because the previous checks have already determined that the file is a threat and have dealt with it.

F l o w — b ase d antivirus scanning order. The following figure illustrates the antivirus scanning order when using flow-based scanning i. The antivirus scan takes place before any other antivirus-related scan. If file filter is not enabled, the file is not buffered. The antivirus scanning engine relies on a database of virus signatures to detail the unique attributes of each infection. The antivirus scan searches for these signatures, and when one is discovered, the FortiGate unit determines the file is infected and takes action.

All FortiGate units have the normal antivirus signature database but some models have additional databases you can select for use. Which you choose depends on your network and security needs. These viruses are the greatest threat. The Normal database is the default selection and it is available on every FortiGate unit.

E x t e nd e d Includes the normal database in addition to recent viruses that are no-longer active. These viruses may have been spreading within the last year but have since nearly or completely disappeared. These are viruses that have not spread in a long time and are largely dormant today. Some zoo viruses may rely on operating systems and hardware that are no longer widely used. If your FortiGate unit supports extended, extreme, or flow-based virus database definitions, you can select the virus database most suited to your needs.

If you require the most comprehensive antivirus protection, enable the extended virus database. The additional coverage comes at a cost, however, because the extra processing requires additional resources. The first three antivirus features work in sequence to efficiently scan incoming files and offer your network optimum antivirus protection. The first two features have specific functions, the third, heuristics, protects against new, or previously unknown virus threats.

To ensure that your system is providing the most protection available, all virus definitions and signatures are updated regularly through the FortiGuard antivirus services. These updates can be scheduled as often as on an hourly basis. From here you can set the updates to occur on a consistent weekly, daily, or even hourly basis. If the file passes the file pattern scan, the FortiGate unit applies a virus scan to it.

G r ay w a r e protection. Grayware scanning is an optional function and must be enabled in the CLI if it is to be scanned for along with other malware. Grayware cannot be scanned for on its own. While done as a separate step, antivirus scanning must be enabled as well. After an incoming file has passed the grayware scan, it is subjected to the heuristics scan.

The FortiGate heuristic antivirus engine, if enabled, performs tests on the file to detect virus-like behavior or known virus indicators. In this way, heuristic scanning may detect new viruses, but may also produce some false positive results. You configure heuristics from the CLI. This page will also allow the configuration of connections to the FortiGuard Center and how often to check for updates to the antivirus files.

Fo r t i G u a r d Botnet protection. Protection from having your system being controlled by a botnet is achieved by detecting and blocking connection attempts to known botnets. This feature also includes connections to known phishing sites. The latest Botnet database is available from FortiGuard. You can also block, monitor, or allow outgoing connections to Botnet sites for each FortiGate interface.

Both the DNS Filter security profile and Botnet protection feature are only available for proxy-based inspection. As of FortiOS 5. This was removed, but the term quarantine was kept to describe keeping selected source IPs from interacting with the network and protected systems. This source IP ban is kept in the kernel rather than in any specific application engine and can be queried by APIs. Both IPv4 and IPv6 version are included in this feature. To configure the antivirus profile to add the source IP address of an infected file to the quarantine or list of banned source IP addresses edit the Antivirus profile, in the CLI as follows:.

If the quar-src-ip action is used, the additional variable of expiry time will become available. This variable determines for how long the source IP adddress will be blocked. The maximum days value is The maximum hour value is 23 and the maximum minute value is The default is 5 minutes. Not every piece of malware has a signature yet.

This is especially true of new malware and new variations on existing malware. FortiOS can upload suspicious files to FortiSandbox where the file will be executed and the resulting behavior analyzed for risk. If the file exhibits risky behavior or is found to contain a virus, a new virus signature is created and added to the FortiGuard antivirus signature database.

The next time your FortiGate unit updates its antivirus database it will have the new signature. A file is considered suspicious if it does not contain a known virus and if it has some suspicious characteristics. The suspicious characteristics can change depending on the current threat climate and other factors. Fortinet optimizes how files are uploaded as required.

To configure an Antivirus profile to enable the use of the FortiSandbox check the checkbox next to S e n d Files to Fo r t i S a ndbo x Cloud for Inspection — this requires you have a FortiCloud account active. Sending files to the FortiSandbox Cloud does not block files that it uploads. Instead they are used to improve how quickly new threats can be discovered and signatures created for them and added to the FortiGuard antivirus database.

The Advanced Threat Protection dashboard widget shows the number of files that your FortiGate unit has uploaded or submitted to FortiSandbox. C li e n t Comforting. When proxy-based antivirus scanning is enabled, the FortiGate unit buffers files as they are downloaded. Once the entire file is captured, the FortiGate unit scans it. If no infection is found, the file is sent along to the client. The client initiates the file transfer and nothing happens until the FortiGate finds the file clean, and releases it.

Users can be impatient, and if the file is large or the download slow, they may cancel the download, not realizing that the transfer is in progress. The client comforting feature solves this problem by allowing a trickle of data to flow to the client so they can see the file is being transferred. The default client comforting transfer rate sends one byte of data to the client every ten seconds. This slow transfer continues while the FortiGate unit buffers the file and scans it.

If the file is infection-free, it is released and the client will receive the remainder of the transfer at full speed. The client does not receive any notification of what happened because the download to the client had already started. Instead, the download stops and the user is left with a partially downloaded file. If the user tries to download the same file again within a short period of time, the cached URL is matched and the download is blocked.

The client receives the Infection cache message replacement message as a notification that the download has been blocked. The number of URLs in the cache is limited by the size of the cache. Client comforting can send unscanned and therefore potentially infected content to the client.

You should only enable client comforting if you are prepared to accept this risk. Keeping the client comforting interval high and the amount low will reduce the amount of potentially infected data that is downloaded. E n a b l e and configure client comforting. Scroll down to the C o mm o n Options section and check the box next to C o m f o r t Clients. This will set the option on all of the applicable protocols. The ability to set this feature on a protocol by protocol basis exists in the CLI.

Select O K or Apply to save the changes. Select this Proxy Options profile in any security policy for it to take effect on all traffic handled by the policy. The default values for Interval and Amount are 10 and 1, respectively. This means that when client comforting takes effect, 1 byte of the file is sent to the client every 10 seconds. You can change these values to vary the amount and frequency of the data transferred by client comforting.

Downloaded files can range from a few Kilobytes to multiple Gigabytes. Image the memory required for a team of developers to all download the latest Linux OS distribution at once, in addition to the normal requirements of the firewall. To give you some piece of mind, the chances of malware being in a large file like those is much smaller than in a smaller single Megabyte file, so the threat is somewhat limited, but you will probably want to use your computers antivirus software to scan those large files after they have been downloaded.

Therefore a threshold must be set to prevent the resources of the system from becoming overloaded. By default the threshold is 10 MB. Any files larger than the threshold will not be scanned for malware. With a maximum file size threshold in place, it must now be determined what is to be done with the files that are larger than threshold. There are only 2 choices; either the file is passed through without being scanned for malware or the file is blocked. The default action for oversized files is to pass them through.

This will reveal an additional option, Threshold MB. The threshold of the files is set based upon the protocol being used to transfer the file. In the CLI and configuration file, the threshold variable is found in each of the protocol sections within the profile. Changing the value in this field will change the oversize-limit value for all of the protocols. If you wish to change the oversize-limit value on all of the protocols covered in a Proxy Option profile you have two options.

You can go into the CLI and change the value manually within each of the protocol sections. You can use the GUI to temporarily block oversized files, and when configuring it change the threshold to the new value that you want. Apply this setting. Then go back to the profile and turn off the block setting. If you now go into the CLI you will find that the configuration file has retained the new oversize-limit value.

The antivirus scanner will open archives and scan the files inside. Archives within other archives, or nested archives, are also scanned to a default depth of twelve nestings. You can adjust the number of nested archives to which the FortiGate unit will scan with the uncompressed-nest-limit CLI command.

Further, the limit is configured separately for each traffic type. C on f i gu r i n g archive scan depth. That is, archives within archives will be scanned five levels deep. When checking files for viruses, there is a maximum file size that can be buffered. The company went public in November The company was renamed ApSecure in December and later renamed again to Fortinet, based on the phrase "Fortified Networks.

Fortinet introduced its first product, FortiGate, in , followed by anti-spam and anti-virus software.
