Metadata Removal - Purging Your Documents of A Hidden Threat
When you talk about information security, most people think in terms of antivirus software, firewalls or password protection. Few are familiar with the phrase "metadata" or the associated, hidden risks that occur every day such as unintentional public exposure of private information. Metadata is a tremendous threat to information security that is growing rapidly, in most part due to a lack of understanding. There are, however, steps that can be taken to guard against the unintended uses of metadata in your organization and to remove this hidden threat.
Metadata is generated by almost all Microsoft Office documents. It is the hidden (or not so hidden) text including employee names, comments, types and IDs of computers, deleted text, previous document versions, etc. found in Microsoft Word, PowerPoint and Excel documents. When these documents are created, edited or saved, metadata is automatically added. While this happens most often in Word documents using the "track changes" feature, it also occurs with other Microsoft Office products, including PowerPoint and Excel. Email (specifically Outlook) is a major contributor to the metadata problem also. All of these products compromise your supposedly confidential comments and make them available for the general public to see.
When engaged properly, metadata is useful. It was initially designed to save time and create a smoother workflow. However, it has the potential to create problems in the wrong hands. Different types of information can be unwittingly disclosed, including the following:
Where are the risks? Throughout the features of Microsoft Word, Excel and PowerPoint documents, among other places. They can also be compounded by emailing these documents via Microsoft Outlook.
Software Features That Create Metadata
What is the solution for the metadata threat? Create a custom-designed process using specifically selected technology to ensure appropriate information security at the messaging and document levels.
Simply stated, you'll need a complete system that integrates seamlessly with MS Office suite and works with little effort on the user's part to protect documents during the creation, editing and sharing phases. This may include secure email, automated extraction of metadata from documents and the implementation of other appropriate security controls throughout all departments. The solution takes specific, automated processes to ensure your organization doesn't fall victim to embarrassing discoveries and/or legal action.

During his run for US Senate, Minnesota candidate, Mike Ciresi was baffled by a number of anonymous email messages with Microsoft Word documents attached that questioned his ethics. After several months, a Ciresi aid uncovered hidden text in the attached Microsoft Word files that linked the emails to members of Ciresi's campaign opponent.
In June 2003, the "Dodgy Dossier" incident broke in the United Kingdom surrounded by much debate and controversy. Metadata was used to trace the authorship of a British security document justifying the war in Iraq to somewhere outside of Great Britain. Much of the work had been plagiarized from various unaccredited sources, most notably from a postgraduate thesis published on the Internet. Metadata showed that editing had been done to the weapons dossier by the British Government to make the case of Saddam's ability to produce weapons of mass destruction.
