The Need For Port
Blocker:
- Portable Systems that are connected behind the
firewall may not be properly patched and pose a risk
to the enterprise.
- Users who refuse patches for any reason may
effect other nodes within your network.
Through the use of our new Port-Blocker/ Quarantine
technology computers can be “blocked” or
“Quarantined” based on the severity of the required
patches. For example, if an administrator chooses to
quarantine a system with “important updates”, then
that system is blocked if it has any outstanding
patches with the severity of “important” and above.
If a system is quarantined, the agent on that unit
installs PortBlocker, and starts the service.
PortBlocker can be administered either individually
or by groups. In a group quarantine administrators
can selectively “unquaratine” users as they become
compliant.
This is very effective with known applications that
pose security risks by design. As an example Instant
Messenger is know to convey viruses. PortBlocker can
shut down ports used by Instant Messenger or any
other application regardless of patch status.
