Security solutions for a changing world You wouldn t leave your front door unlocked if you were going out for the day, so why do the same with your business? In today s rapidly evolving business environment, you need to be able to engage with emerging collaborative technologies to stay relevant and competitive. Keeping your data secure yet mobile is more important and more complex than ever. To avoid the potentially serious implications of data leaks and regulatory breaches, you must inspect the information you create and share. Your content needs to be reviewed constantly, in real time to ensure compliance with your information governance policies. Which is where deep content inspection technology comes in. The SECURE File Gateway enables organisations to add powerful file content inspection features to existing applications and services, meaning that you can ensure the integrity of your data as it moves around, and before it leaves your organisation. Only by understanding your content can you protect your information assets and make better decisions with your data. Clearswift s solutions are renowned for providing mission-critical content filtering for thousands of customers and millions of users worldwide. The award-winning Clearswift content inspection engine sits at the heart of the File Gateway and has a proven track record of secure, robust, high-performance deep content inspection. Use-cases include: Enforce data usage policy Prevent data leakage Ensure regulatory compliance Prevent reputational damage Avoid malware cross-contamination Automate existing processes improving efficiency and consistency SECURE File Gateway details 2 Recommended hardware Processor: Intel quad-core processor Memory: 8GB RAM System disk: (7,200rpm) Configuration: No RAID required The following operating systems are supported: Windows Server 2008 R2 Standard, with SP1 Windows Server 2008 R2 Enterprise, with SP1 Red Hat Enterprise Linux for Servers (64-bit) version 6.1
Automated inspection If automated applications and services are moving files containing any information social security numbers, or credit card numbers for example then there s a risk that sensitive information may be leaked. The SECURE File Gateway can help significantly reduce this risk by automating the inspection process, identifying content based on policy, and preventing unexpected disclosure of sensitive or personal information. Easy integration and policy configuration The SECURE File Gateway integrates with your existing applications and services and works with them to perform its inspection. An intuitive, web-based user interface (UI) makes it easy for administrators to manage, audit and report on the file s progress and policy outcomes. We ve designed the integration process to be as easy and simple as possible to aid rapid deployment. Put simply, integration involves moving the relevant files to the File Gateway s input directory and then subsequently collecting them from the output directory once the inspection is complete. If a policy violation is encountered, the suspect files are moved into a separate quarantine directory from where the violation can be managed. HOST APPLICATION Data + Rules Result SECURE File Gateway Large files The SECURE File Gateway can handle very large files. The standard version can handle files up to 4GB, while there is an option to handle files up to 16GB in size. If anti-virus is installed, the File Gateway will segment the file appropriately so that effective scanning for viruses can also take place. 3
Avoid sensitive data leaks The File Gateway is commonly used to inspect a file s content as it moves from one location to another. By inspecting the file before it moves, the risk of sensitive data leaks is considerably reduced especially in scenarios where both locations are networks with different levels of security. For example, one network may be a high security domain and the other low security; alternatively a private Intranet network and a public facing website. In both of these examples there s a real risk that the information contained within the file could be valuable in one location but represent a data leak in the other. Recognise, understand and process The File Gateway s content inspection engine recognises over 150 different file or format types. It uses strong signature and data parsing techniques that ignore unreliable external indicators, like file extensions. The engine performs recursive decomposition, and systematically opens and searches within archive files like ZIP and TAR to locate all embedded objects for example images, or active content within Office documents. Inspection continues until there is nothing left to process. By recognising particular file types, it is possible to set a policy to decide which file types are acceptable, and which should be blocked. The inspection also extends to textual content: the words and phrases contained within the files. aa Textual search The SECURE File Gateway provides powerful text analysis capabilities to search for words, phrases and expressions of any format and in any language. Expressions can be keywords, phrases or regular expressions Predefined patterns such as credit card numbers, social security numbers (US), NI numbers (UK) and IBAN numbers Each expression can have its own weighting to allow occurrence counts to be defined Logical operators: AND, OR, XOR, ANDNOT Proximity operators: NEAR, BEFORE, AFTER, FOLLOWEDBY Search within body, headers, footers, meta-data or whole document By recognising the presence of terms such as Top secret in the footer of Word documents, or credit card numbers in Excel worksheets, it is possible to build policies that strictly control which data is processed through the system, and more importantly, which isn t. 4
Malware, active code and damaged data In addition to checking for content violations, the File Gateway is compatible with Sophos anti-virus. This means the data you process can be checked to ensure it doesn t contain suspicious content or malware that could potentially cause cross-infection to other networks or organisations. The SECURE File Gateway also has its own capabilities when it comes to blocking potential malware: It has rules to detect active code, such as macros in Microsoft Office, or scripts in Adobe PDF It can block suspicious data that doesn t match any recognised format, appears to be corrupt, or has been tampered in some way. Unusual data could indicate that malware is trying to exploit a weakness and cause a buffer overflow in an application It quarantines encrypted data that cannot be inspected GUARDS GUARDS LOW SECURITY NETWORK HIGH SECURITY NETWORK Sample uses cross domain transfer While many cross-domain solutions have the bandwidth to transfer large volumes of data, adding content checking can introduce bottlenecks, particularly with large files. The Clearswift SECURE File Gateway permits the transfer of very large files up to 16GB in size which are verified against a defined content security policy. 5
FTP S/FTP MFT APP Authentication File Validation Encryption SCP Input data Output data SECURE File Gateway Sample uses managed file transfer For the fast and secure transfer of large files, managed file transfer (MFT) products have traditionally been the quickest and the most economical. These solutions typically focus on the transport methods of the delivery, rather than on the content being sent. However, organisations wanting to ensure all of their points of egress are covered for data security should add the SECURE File Gateway to the process. This will ensure that sensitive data cannot be mistakenly transferred to the wrong location. Sample uses collaboration Collaboration tools are big business; SharePoint for example has over 100 million users, and there are many other similar products. The business benefits of tools like this are widely recognised, but with sharing comes risk. People make mistakes and accidents happen, so safeguards ensuring that only appropriate content is shared can be vital. If you are using SharePoint to allow your partners to access your data, how do you prevent internal documents accidentally being posted for partners to see? By integrating the Clearswift SECURE File Gateway into the publishing process, accidental disclosure can be prevented. Data protection made simple Clearswift s trusted deep content inspection capabilities ensure peace of mind for thousands of customers worldwide.
