How StripIT works

StripIT® operates as an SMTP relay when operating stand-alone or as a content scanner when StripIT® is integrated with MIMEsweeper for SMTP.

StripIT® can process OpenOffice and Microsoft Office word processor, spreadsheet and presentation documents and can be configured to:

  • detect and report via an appropriate classification or
  • detect and clean, again reporting its action via an appropriate classification

StripIT® detects:

  • Openoffice.org Basic, Javascript, BeanShell and Python scripting languages
  • Microsoft Office 97-2003, 2007-2010 Macros and Microsoft Office 2003 XML.

Some Microsoft Office documents may contain orphaned data structures. This can occur as a result of using fast save, which adds new data to the end of a document, without removing old data. Although this data is not directly accessible, it can contain anything, and it may be possible for the recipient to reactivate it. StripIT®provides a way to remove these orphaned data structures.

StripIT® identifies the presence of IRM access permissions in Microsoft Office documents.It allows these to be classified as "Not Checked" and quarantined by MIMEsweeper for SMTP. StripIT® uses file type signatures and file name masks to identify files to strip.
