Application Description
Protect OWA sessions from unauthorized access.
NavGuard monitors OWA usage and identifies when a user is creating security vulnerability by navigating away from an active OWA session without first logging off. In a public environment or on a shared computer where the original user leaves the OWA session active because they had forgotten that it was open, the next user on that computer will have unauthorized access to that OWA session without being required to re-authenticate. Even with ISA Server installed, this security vulnerability exists.
NavGuard’s user-friendly prompt alerts the user that a security event is about to occur and offers the user the option of logging off before continuing to another page or returning to the active OWA session. In this way, NavGuard prevents users from creating a security exposure by navigating away from their OWA session.
NavGuard protects OWA accounts from unauthorized access, extends the security provided by forms based authentication (FBA) and 3rd party security products to offer greater protection for OWA users.
NavGuard is activated when a user:
- Enters a new URL in the address bar
- Presses the home button.
- Presses the Refresh button.
NavGuard can also block users from accessing OWA with older browsers. Up to date browsers have additional safeguards to reduce security vulnerabilities.
NavGuard is available for Exchange 2010, 2007 and now Exchange 2003.
NavGuard for Outlook Web App/Access (OWA) has not been reviewed by any customers.
