SheepDip
Safe testing of untrusted media and safe inter-network data transfer
A sheep-dip is a dedicated computer which is used to test files for viruses before they are allowed into a company or institution. The SheepDip Project provides an improvement on conventional systems. Third-party antivirus protection is monitored in real time with another program, to make a more secure sheep-dip.
