Security and Protection Spyware and Virus Protection The Barracuda Web Security Gateway uses a continually updated database to identify and block access to sites known to host spyware and viruses. It also detects installed spyware trying to access the Internet. Upon discovery, it blocks the spyware activity and notifies the administrator. By using dual-layer virus blocking, decompressing archives, and blocking file types, the antivirus engine in the Barracuda Web Security Gateway protects networks from aggressive viruses. Advanced Threat Protection Barracuda Advanced Threat Protection (ATP) implements full system emulation, providing deep visibility into malware behavior. Files are checked against a dynamic cryptographic hash database, and any match is immediately blocked. If a match is not immediately found, or in case the file is unknown, it is delivered to our virtual sandbox for detonation where malicious behavior can be safely discovered. Barracuda ATP offers Administrators file-type-based control over attachment scanning policies and is used in conjunction with our updated virus scanning engines to maintain complete protection of an organization's network. The Barracuda Advanced Threat Protection is an optional subscription available with WSG firmware 11. Learn More about Barracuda's Advanced Threat Protection Chromebook Security Extension The new Barracuda Chromebook Security Extension is a Chrome browser extension that enables remote enforcement of web security policies. This is especially useful for K-12 environments. The extension works both on- and off-network, providing security for students, even when they take their Chromebooks home. Web Application and Social-Media Regulation The Barracuda Web Security Gateway provides granular control over Web 2.0 sites and web applications, including social media platforms. Scanning and inspecting SSL-encrypted traffic for specific categories and domains enable granular policy enforcement. Administrators can also configure the Barracuda Web Security Gateway to monitor and archive outbound web application communications like Facebook posts, tweets, and web-based email to a message archiving solution, such as the Barracuda Message Archiver. These messages can be indexed and then mined for forensic analysis. Suspicious activity alerts can also be generated using predefined or customized categories. Application Control In addition to standard port/protocol-based policies, the Barracuda Web Security Gateway uses real-time deep packet inspection technology to analyze protocols independent of their port of destination servers. By integrating Layer 7 protocol analysis with policy controls, the Barracuda Web Security Gateway enables complete control over application usage. Content Filtering The Barracuda Web Security Gateway provides flexible controls for pinpoint regulation of online activity. Administrators can create policies that control user access to 99.7 percent of commonly visited websites using 95 content categories including pornography, violence, hacking, sports, news, dating, shopping, chat, and more. Content filtering policies can be customized to restrict specific websites or look for patterns in web addresses. The Barracuda Web Security Gateway's image/multimedia safe search feature prevents search engines such as Google, Yahoo, and Bing from displaying objectionable thumbnail images in search results. Administrators can also create policies that control web-file downloads based on file type. SSL Inspection Organizations can control online content normally hidden by SSL. This includes content found in social-media platforms, web-based email, and search engines. Administrators can specify domains and URL categories for which SSL-encrypted traffic will be decrypted and scanned for malware and policy. Not only can organizations restrict entire platforms, it’s now possible to enforce granular access for secure websites (e.g., YouTube). The Barracuda Web Security Agent The Barracuda Web Security Agent (WSA) is a tamper-proof client that can be installed on remote, off-network laptops or desktops to help implement a consistent web security policy across localized and distributed workforces. The Barracuda WSA supports both Windows and Mac OS X.
