Protecting against the leading causes of data breach
With the trend of large scale data breaches continuing, a 2008 Clearswift survey of over 1,000 IT and security professionals found that 94% of those polled agreed their data loss incentives was viewed as “important”, “very important” or “imperative” to their organization. Yet, the same poll found that since the introduction of data protection standards, 57.2 % of organizations could only increase their annual IT budget by a mere 10% or less to accommodate the demands of Data Loss Prevention (DLP). This whitepaper demonstrates how organizations can prevent the four leading causes of data breach.

10 Essential Steps to Email Security
Every enterprise has to find a balance between security and the ability to carry on conducting business freely. This short guide is about finding that balance. By following some basic principles, there’s no reason you can’t let legitimate business email move into, out of and within your enterprise while stopping the things that cause damage: viruses, spam, spyware, trojans, phishing, Denial of Service attacks, the loss of sensitive data and the collection of illegal, immoral and just plain offensive material.

Email Security: beyond the hype and hyperbole
Every business depends on email and the Internet. But reading the press, it's tempting to believe that the risks sometimes outweigh the benefits. Viruses, phishing, spyware, spam, trojans, worms, pornography, hate mail and the like are presented, particularly by the press, as some sort of remorseless digital plague sent down from on high to damage businesses everywhere.

Policing Web Usage: Securing the Back Door
It was all over the papers. Over 200 civil servants in a single department had been caught downloading porn. They had downloaded more than two million pages during an eight month period, including eighteen thousand images of child pornography. Sixteen people were fired, one was prosecuted and the department’s reputation was badly damaged. In another case, a software organization had to cease its development program because a contractor had stolen its source code – using webmail from inside the corporate network. All these cases, and many more like them, share a common theme: organizations suffering serious damage to their reputation or financial well being due to their employee’s misuse of the web.

Protecting Against Web 2.0 Threats
In the last few years’ people have started using the Web in new and different ways. The Internet is evolving from a collection of information and ecommerce sites into a platform for the next generation of applications and business services facilitating real collaboration and sharing. Called Web 2.0 by Tom O’Reilly of O’Reilly Media in 2004, the new world is characterized by a wave of new jargon, brands and web-based experiences: MySpace. FaceBook. Wikipedia. Flickr. Twitter. YouTube. Mashups. Blogs. Newsfeeds (See our Demystifying Web 2.0 Guide for more information on the whole Web 2.0 phenomenon).

A Comprehensive Approach to Web Filtering
Not all the content available on the Internet is good. Not everything that a search robot could be programmed to find would be appropriate in an organization, a lot of available content is not work related. It diverts employees from what they should be doing. Or corrupts data within the network. Or covertly allows siphoning off of company confidential information. There are real and definite risks in allowing everything that is on the Internet into your organization.

The Threat Within Whitepaper: The dangers of unrestricted employee use of corporate IT systems
Conventional wisdom has led us to believe that external security threats - such as spam, viruses, phishing, trojan horses - cause the majority of security incidents. While this may be true, too few companies are paying sufficient attention to the very significant issue of internal threats. On average, there is eight times as much email sent internally as there is externally. Together with unrestricted web usage, the threat from breaches of security originating from inside the company's firewall can be punitive. Government statistics back this claim up: according to the 2004 DTI's Information Security Breaches Survey (produced by the UK DTI), one third of British businesses say that the source of their worst security incident is internal.
