This document focuses on the security features provided by Microsoft and why it is still essential for an organization to deploy the SECURE Email Gateway in front of the online version of Exchange.

SECURE ICAP Gateway

ICAP stands for Internet Content Adaption Protocol and it is a protocol aimed at providing inspection for web content. An ICAP client routes HTTP content to an ICAP server in order to process it or adapt the content. The adapted content is then returned to the ICAP client in the form of an HTTP response or an HTTP request.

Clearswift SECURE Email Gateway can detect PGP encrypted messages. When a message contains a PGP encrypted attachment, it is not able to process it and the message is treated as Unknown Binary. Inter Engineering was able to extract common patterns in files encrypted with PGP or with the open source counterpart GnuPG (GPG).

Two-factor authentication (2 factor authentication or 2FA) is the authentication process where two of the three possible factors of authentication are combined.

The possible factors of authentication are:

  • something the user has (e.g. a token, a mobile phone, a USB, a key fob)
  • something the user is (e.g. face or voice recognition, behavioral biometrics, fingerprint, retina or iris scan)
