Cytat:What’s New in FortiClient (Windows) 5.4.0
AntiVirus
Advanced Persistent Threats
FortiClient 5.4.0 has enhanced capabilities for the detection of Advanced Persistent Threats (APT). There are two changes added in this respect:
l Botnet Command and Control Communications Detection l FortiSandbox integration
Botnet Communication Detection
Botnets running on compromised systems usually generate outbound network traffic directed towards Command and Control (C&C) servers of their respective owners. The servers may provide updates for the botnet, or commands on actions to execute locally, or on other accessible, remote systems.
When the new botnet feature is enabled, FortiClient monitors and compare network traffic with a list of known Command and Control servers. Any such network traffic will be blocked.
FortiSandbox Integration
FortiSandbox offers the capabilities to analyse new, previously unknown and undetected virus samples in realtime. Files sent to it are scanned first, using similar Antivirus (AV) engine and signatures as available on the FortiOS and FortiClient. If the file is not detected, but is an executable file, it is run (sandboxed) in a Microsoft Windows virtual machine (VM) and monitored. The file is given a rating or score based on its activities and behaviour in the VM.
FortiClient integration with the FortiSandbox allows users to submit files to the FortiSandbox for automatic scanning. When configured, FortiClient will send supported files downloaded over the internet to FortiSandbox if they could not be detected by the local real-time scanning. Access to the downloaded file is blocked until scanning result is returned.
As FortiSandbox receives files for scanning from various sources, it collects and generates AV signatures for such samples. FortiClient periodically downloads the latest AV signatures from the FortiSandbox, and applies them locally to all real-time, as well as on-demand, AV scanning.
Enhanced Real-Time Protection Implementation
The Real-Time Protection (RTP) or on-access feature in FortiClient uses a tight integration with Microsoft Windows to monitor files locally or over a network file system as they are being downloaded, saved, run, copied, renamed, opened or written to. The FortiClient driver coupling with Windows has been re-written to use modern API's provided by Microsoft. All basic features remain the same, with a few minor differences in behaviour. Some noticeable performance enhancements could be observed in various use case scenarios.
