Continuous Download The Traditional Anti-Virus engine acts as a proxy which caches the scanned file before delivering it to the client for files that need to be scanned. When nesting or compression exceeds limit or extraction fails: Fildtype data is either allowed or blocked based on the response of the state-of-the-art Traditional Anti-Virus engine.
Filetypd Proactive and Stream Mode Detection Traditional Anti-Virus scanning can be enabled in either the proactive or stream detection mode.
By default, any file type that is not identified as non-archive is assumed to be an archive and the Traditional Anti-Virus engine tries to expand it. The following signature update methods are available the default update interval is minutes for all methods:. This limit protects the gateway and destination client from attacks that employ deep nesting levels.
Using Traditional Anti-Virus
When Traditional Anti-Virus engine fails to initialize: A similar problem may arise when using client applications with short timeout periods for example, certain FTP clients to download large files. Archives and all other file types are recognized by their binary signature.
Limits the file size that is allowed to pass through the gateway. GIFwhich can be spoofed. Note – An email is treated as an archive dmx as a result it giletype not affected when the file exceeds the limit.
dmz – All Pages
Stream mode – the kernel processes the traffic for the selected protocols on the stream of data without storing the entire file. With the slider, select a protection level: The fileetype is allowed or blocked based on the response of the Traditional Anti-Virus engine.
By default, all unrecognized file types are scanned.
For example, you can decide not to scan traffic passing from external networks to diletype DMZ, but to still scan traffic passing from the DMZ to internal networks and from the external to internal networks. When a file exceeds size limit: Clear the checkbox to enable stream mode detection.
Its security level lies between trusted internal networks, such as a corporate LAN, fjletype non-trusted external networks, such as the Internet. Configuring File Types 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. Some file types for example, Adobe Acrobat PDF and Microsoft Power Point files can open on a client computer before the whole file has been downloaded.
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.
Set the slider to Block. Maximum file size to scan: For example, picture and video files are normally considered safe. See Continuous Download for further information.
Continuous Download options are only relevant if the scan is set to Proactive Detection. Download signature updates every x minutes: Using this method the default is fairly intuitive and does not require the specification of hosts or networks. Tiletype upgraded systems, the detection mode that is activated by default is dependent upon whether the Traditional Anti-Virus feature was previously activated or not.
Internal Access to DMZ
Files specified as this type are considered to be safe. Proactive detection mode – a comprehensive, file-based Traditional Anti-Virus solution where traffic for the selected filetyoe is trapped in the kernel of the Security Gateway and forwarded to the security server for scanning.
Traditional Anti-Virus scanning is performed only on traffic that is allowed by the Security Rule Base. This mode uses sandboxes and heuristics to detect malicious code throughout the traffic as opposed to passive signature based detection. The data is allowed or blocked based on the response of the kernel. Archive File Handling These file handling archiving options are available: Performs Traditional Anti-Virus file scanning according to the settings in the different services pages.
Updates of virus signatures can be initiated at any time.
