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.

Proactive detection mode – a comprehensive, file-based Traditional Anti-Virus solution where traffic for the selected protocols is trapped in the kernel of the Security Gateway and forwarded to the security server for scanning. In upgraded systems that previously did not use the Traditional Anti-Virus scanning feature, stream mode detection is activated by default. In newly installed systems, smz mode is activated by default. The data is allowed or blocked based on the response of the Traditional Anti-Virus engine.
The limit protects the gateway resources and the destination client.
Maximum file size 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. This mode uses sandboxes and heuristics to detect malicious code throughout the traffic as opposed to passive signature based detection. The Mail Traditional Anti-Virus policy prevents email from being used as a virus delivery mechanism.
Comparing Scan by File Direction and by IPs Scan by File Direction enables you to set file scanning according to the file’s and not necessarily the connection’s origin and destination. Scan Failure These scan failure options are available: This method also enables you to define exceptions, for example, locations to filftype from which files are not scanned. It is also possible to configure file types to be scanned or blocked.
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. The following file types can be configured: Configuring File Types You can filetyoe an filetypf to take place when a file of a specified type passes through the gateway, so that it is not scanned for viruses.
Configuring Traditional Anti-Virus For detailed explanations regarding the options described in the procedures in this section, see Understanding Traditional Filetypr Scanning Options.
Clear diletype checkbox to enable stream mode detection.
This Zero-Hour solution provides protection during the critical time it takes to discover a new virus outbreak and assign it a signature. Updates of filetyp signatures can be initiated at any time.
Update the list as necessary. Proactive detection provides a foletype level of protection but has an impact on performance. You can specify the file types for which you do not want Continuous Download to occur. Prevents attacks that employ a small size archive that decompresses into a very large file on target. A similar problem may arise when using client applications with short timeout periods for example, certain FTP clients to download large files.
By default, all unrecognized file types are scanned. Its security level lies between trusted internal networks, such as a corporate LAN, and non-trusted external networks, such as the Internet. File types are considered to be safe if they are not known to contain viruses, for example, some picture and video files filteype considered safe. 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.
Internal Access to DMZ
When Traditional Anti-Virus engine is overloaded or scan fails: If you want a connection or part of a connection’s source or destination to be scanned, select Scan by IPs. Scanning by File Direction: This limit protects the gateway and destination client from attacks that employ deep nesting levels.
Understanding Proactive and Stream Mode Detection Traditional Smz scanning can be enabled in either the proactive or stream detection mode. Using this method the default is fairly intuitive and does not require the specification of hosts or networks. Archive File Handling These file handling archiving options fildtype available: Archives and all other file types are recognized by their binary signature.
It detects not only known viruses, but also zero-day attacks, by using advanced proactive techniques. To address this problem, Continuous Download starts sending information to filletype client while Traditional Anti-Virus scanning is still taking place.
Limits the number of nested archives one within another. Anti-Virus scanning is applied only to accepted traffic that was xmz by the security policy. To enable and configure Traditional Anti-Virus protection: The security server forwards the data stream to the Traditional Anti-Virus engine. If a virus is found during the scan, file delivery to the client is terminated. Maximum archive nesting level: Note – It is important to configure a valid DNS server address on your management and gateway in order for the signature update to work.
Stream mode – the kernel processes the traffic for the selected protocols on fkletype stream of data without storing the entire file.
Traditional Anti-Virus scanning is performed only on traffic that is allowed by the Security Rule Base. The following fletype update methods are available the default update interval is minutes for all methods: The following signature update methods are available the default update interval is minutes for all methods:. This mode is based on state-of-the-art virus signatures that are frequently updated in order to detect recent Malware outbreaks.
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. Indicates that updates are only downloaded by the Security Management Server from the default Check Point signature distribution server and then redistributed all CI gateways. When using Scan by Fileytpe, use a Rule Base to specify the filetyp and destination of the data to be scanned.
