![]() The Sandbox also monitors all file, memory, registry and network activity as well as sandbox evasion techniques. This includes deep learning analysis, exploit detection, and CryptoGuard to detect active ransomware encrypting files in real time. To identify threats based on their behavior, SophosLabs has integrated the latest protection technologies from our industry-leading Intercept X next-gen endpoint product into the Sophos Sandstorm sandbox. Because it’s cloud-based, there’s no additional software or hardware required, and no impact on firewall performance. This makes it remarkably fast and effective at identifying new threats and new variants of existing threats, particularly with files which are not easily sandboxed, such as password protected documents.Īt the same time a file is submitted for Threat Intelligence Analysis, it is also submitted for dynamic behavioral analysis in our cloud sandbox environment. ![]() It compares the new file with millions of known good and bad files in the SophosLabs database to render a verdict in seconds without the need to execute it in real-time. Threat Intelligence uses multiple machine learning models to analyze the characteristics, features, genetics and global reputation of the file. Let’s take a look at what happens to a file that is scanned in a bit more detail: Threat Intelligence Analysis This last step is important, as many advanced malware solutions on firewalls release a file to the end-user before the analysis is complete, potentially resulting in an extensive and expensive cleanup if the file is then ultimately convicted as a threat once all analysis is finished. It then provides a detailed overview of the results and only releases the file to the downloader or email recipient if the file is declared safe. When XG Firewall’s Xstream DPI engine performs AV analysis on a file entering the network and determines there is active code, it holds the file temporarily and sends it to the SophosLabs Intelix service in the cloud for both static and dynamic (sandbox) analysis. Both are powered by SophosLabs Intelix which uses machine learning technology, decades of threat research, and petabytes of intelligence, providing unmatched protection against new and previously unseen threats. They work together to identify the latest zero-day threats. XG Firewall v18 includes new machine learning (ML) based Threat Intelligence and a newly enhanced version of Sandstorm Sandboxing, to catch the latest threats. This article highlights the new cloud-based Threat Intelligence and Sandstorm sandboxing technologies which are part of the Sandstorm Protection subscription. These all play a critical role in identifying and stopping the latest zero-day threats. ![]() In previous articles, we covered the Xstream Architecture and the new DPI engine, the new TLS inspection solution, and the Network Flow FastPath. In this fourth in our series of articles on making the most of the great new features in XG Firewall v18, we’re going to specifically focus on the new capabilities in XG Firewall v18 designed to protect against the latest zero-day threats such as new ransomware variants. This result demonstrates the critical need for predictive zero-day threat identification and protection as advanced threats like ransomware become more targeted and evasive. In The State of Ransomware 2020 report, over half the participating companies surveyed across 26 countries reported that they had been hit by ransomware in the past 12 months.
