Secure File Sharing for Defence

PRODUCT SUMMARY

With a priority to responding to tasks and building for the future, Defence organisations demand enhanced capabilities for secure information sharing as part of a drive for digital by default, to harness the transformative power of technology whilst avoiding the burdens of non-standard, bespoke, and ‘locked-in’ methods of exchanging data.

Business Problem

Throughout the defence sector, there is a requirement for improved ways of secure working, whilst reducing cost and optimising performance for sharing nationally sensitive information. Email is commonly used as a suitable collaboration mechanism in many circumstances, however large files need an alternative solution for secure transfer.

Clear guidance is provided by the MOD for the provision of ICT systems in support of national security commitments. These need to meet the associated system accreditation standards of the UK and its international partners. This includes managing policy, procedures, and capabilities effectively to deliver appropriately configured systems that support the need to collaborate, communicate securely, and share information effectively.

However, the risk remains high as with the need to share information comes the risk of exposing the wrong content to unauthorised individuals or organisations. Files that contain confidential information, either visible within the body of the file or hidden within its metadata, can be mistakenly shared. Equally, the reception of files from partners might open a door to embedded malware and external threats hidden within standard file transfers.

Highly Secure Digital File Sharing with Clearswift

Organisations can gain full control of how and when information is shared both internally and externally. Managed data flows can be easily defined to exchange information through a portal to address the need to share large files securely and in a cost-effective manner.

By integrating a layer of Deep Content Inspection and document sanitisation through the ICAP protocol with a best-of-breed Managed File Transfer (MFT) solution, additional information controls can be set in place to enforce security and compliance policies for files being transferred.

The solution helps the MOD to meet accreditation requirements and the wider defence industry partners to meet the risk-based controls imposed by the Defence Cyber Protection Partnership (DCPP) and associated DefStan05-138 standard.

As all file transfer traffic can be directed to pass through this enhanced level of management and security, it overcomes the primary challenge that many consumer-oriented cloud collaboration tools suffer from, particularly as ICT systems migrate to shared or virtualised services.

How Does Clearswift Secure File Sharing Work?

The solution embraces the Clearswift Secure ICAP Gateway, which is a market-leading solution for enhancing cybersecurity infrastructure. It enables the balance to secure and protect sensitive information with the need to continuously collaborate.

The solution provides the ability to apply Deep Content Inspection, Adaptive Data Loss Prevention, and Advanced Threat Protection technologies to align the flow of information to the organisation’s information governance, risk, and underpinning compliance policy requirements. It integrates with Fortra's market-leading MFT solution, GoAnywhere, but can be integrated with any ICAP-compliant device.

Clearswift’s Deep Content Inspection (DCI) capability goes beyond the levels of what is traditionally offered in the market. It is not limited by zip/encryption, file size, analysis timing delays, virtual environment evasion techniques, or multiple embedded document layers. As a result, it offers high detection rates and low impact to minimise false positive rates.

DCI, coupled with document rewrite, can remove both visible and invisible information, as well as active content based on policy. ‘Invisible’ information, including that hidden in comments, document properties, and revision history, creates risk of unauthorised information sharing. While embedded active content in innocuous-looking files can create risk from ransomware and other malware which is activated when the document is opened.

Adaptive Data Loss Prevention (A-DLP) is the non-disruptive removal or transformation of data according to policy (rules), to ensure that information shared complies with prevailing security policies before it is sent to, or received by, the recipient (person, application or system).

Intelligent policy enforcement is applied to only the information that breaks policy and compliance regulations, whilst allowing the rest of the document to continue without disruptive false positives. Adaptive DLP also sanitises documents by stripping out hidden metadata (author, username, server, and software names, etc.) and other sensitive information that can be harvested and used for targeted attacks. Adaptive DLP modifies the information in real-time according to policies rather than a simple masking, to ensure only the acceptable level of information is shared and received, and that sensitive information always remains safe.

Advanced Threat Protection is used to detect and automatically strip out active content in the form of embedded malware triggered executables, scripts, or macros used to extract or hold sensitive data hostage. Clearswift’s Advanced Threat Protection sanitises without delay in delivery, as only the malicious active content is removed, allowing the rest of the file transfer to continue unhindered.

The Clearswift Secure File Transfer solution streamlines the exchange of data between systems, employees, project teams, and collaboration partners. It provides a single point of control with extensive security settings, detailed audit trails, and reports. It is supported by an intuitive interface and comprehensive workflow features that help to eliminate the need for bespoke programs / scripts, single-function tools, and manual processes that were traditionally required.

Features

Designed to scale to enterprise deployments, the system provides:

  • Business-level information asset protection: focused on the asset value, risk profile, and the associated impact of the data associated with it;
  • Secure handling and management: according to the systems that support the communication of clearly identified sensitive information and granular control tomeet policy requirements;
  • Optical Character Recognition & image-based text redaction: enables advanced features for dealing with scanned documents and image files;
  • Sophisticated anti-steganography features: prevent infiltration of malicious code, or exfiltration of sensitive information in images;
  • Coherent and consistent: ensures appropriate sharing of information within and across teams both internally and externally to the organisations that are holding or creating the data;
  • Data flow visibility: necessary controls and visibility of the files flowing to support both audit and compliance under the specific collaboration policy requirements– for example, DCPP;
  • Support for operational requirements: provide cybersecurity monitoring and incident response, and multiple implementations of encryption that are common to the UK Defence community;
  • Compliance with policies and procedures: lays down how information is managed and secured within and across the defence community under DefStan 05-138

Deployment

The Clearswift Secure ICAP Gateway is designed to be deployed stand-alone, or in conjunction with other Clearswift Secure Gateway products to create the Clearswift Aneesya Platform. When deployed with other products, a consistent Deep Content Inspection and policy engine ensures consistent discovery of critical information, DLP policy and Adaptive Redaction functionality for information flow control. The products include:

  • Clearswift Information Governance Server (IGS): enables users to securely register and classify information with the IGS. Compliance Officers are given access to oversee who and what is being registered as well as the ability to track and trace information (not just files) passing across the organisation boundary, in real-time, including information provenance reporting.
  • Clearswift Secure Exchange Gateway: enables data loss prevention policies to be applied to internal email communications, along with the ability to track and control internal information sharing and email segregation functionality without the need for separate infrastructures.
  • Clearswift Secure Web Gateway: offers granular control over what users can access or share online. Flexible, policy-based filtering and content aware inspection extends beyond limiting browsing, to view inside HTTP/S encrypted traffic to prevent phishing and malware attacks and the unauthorised exposure of sensitive information.

Cost

Flexible pricing options are available to suit differing implementation requirements across the varying scale of organisations that constitute the UK defence community. This ensures the solutions are commercially appropriate, affordable and sustainable whilst offering the ability for customers to consolidate their existing security solutions into an integrated platform for both on-premise and cloud delivered services.
