When scanning large files, if the whole file is scanned before being made available, the filetypr may experience a long delay before the file is delivered.
Internal Access to DMZ
With the slider, select a protection level: If Proactive Detection was configured, select Activate Continuous Download to prevent client time-outs when large files are scanned. Scanning by File Direction: Stream detection mode – where traffic is scanned for viruses as it passes through the network on streams of data, without storing entire files and without causing an impact on performance.
In upgraded filetypr that previously used the Traditional Anti-Virus scanning feature, proactive detection is activated by default. This method is useful when Internet access is not available for all gateways or if the dms can only occur once for all the gateways. Set the slider to Block.
The following file types can be configured: The limit protects the gateway resources and the destination client.
Prevents attacks that employ a small size archive that decompresses into a very large file on target. IPS reliably identifies binary file types by examining the file type signatures magic numbers. Note – An email is treated as an archive and as a result it is not affected when the file exceeds the limit.
It detects not only known viruses, but also zero-day attacks, by using advanced proactive techniques. The security server forwards the data stream to the Filtype Anti-Virus engine. File Type Recognition IPS has a built-in File Type recognition engine, which identifies the types of files passed as part of the connection and enables you to define a per-type policy for handling files of a given type.
Advanced Topics – Database – Schema
Files set for scanning are defined in the classic Rule Base, which defines the source and destination of the connection to be scanned. See File Type Recognition for more information. Using this method the default is fairly intuitive and does not require the specification of hosts or networks. Comparing Scan by File Direction and by IPs Scan by File Direction enables you to set file scanning d,z to the file’s and filteype necessarily the connection’s origin and destination.
Download signature updates every x minutes: You can set an action to take place when a file of a specified type passes through the gateway, so that it is not scanned for viruses. The DMZ demilitarized zone is an internal network with an intermediate level of security. When Traditional Anti-Virus engine is overloaded or scan fails: Configuring Traditional Anti-Virus For detailed explanations regarding the options described in the procedures in this section, see Understanding Traditional Anti-Virus Scanning Options.
File Handling The following file handling options are available: The Mail Traditional Anti-Virus policy prevents email from being used as a virus delivery mechanism.
Selecting Data to Scan When using Scan by File Direction, you must select the direction of the data to scan, which depends on whether you want to scan files to or from the internal networks and the DMZ. Maximum file size to scan: Note – Continuous Download is only relevant if you have selected to use the Activate proactive detection option.
The following signature update methods are available the default update interval is minutes for all methods: This mode uses sandboxes and heuristics to detect malicious code throughout the traffic as opposed to passive signature based detection.
For example, you can decide not to scan traffic passing from external networks to the DMZ, but to still cmz traffic passing from the DMZ to internal networks and from the external to internal networks. It is also possible to configure file types to be scanned or blocked. Other formats are considered to be safe because they are relatively hard to tamper with. Stream mode – the kernel processes the traffic for the selected protocols on the stream of data without storing the entire file.
If you want a connection or part of a connection’s source or destination to be scanned, select Filteype by IPs.
File types are considered to be safe if they are not known to contain viruses, for example, some picture and video files are considered safe. Incoming files Outgoing files Internal files through the gateway For a scan by IPs, create rules for the Rule Base to set the source and destination of the data to filteype scanned. Traditional Anti-Virus scanning is performed only on traffic that is allowed by the Security Rule Base.
Using Traditional Anti-Virus
If the file is a compressed archive, the limit applies to the file after decompression the Traditional Anti-Virus engine decompresses archives before scanning them.
When Traditional Anti-Virus engine fails to initialize: Proactive detection provides a high level of protection but has an impact on performance. When using Scan by File Direction, you must select the direction of the data to scan, which depends on whether you want to scan files to or from the internal networks and the DMZ.
Determines whether to scan or block the file. When a file exceeds size limit:
