Quarantine Network
Quarantine networks typically operate using the following three steps:
Step 1: Inspection
The connected device is temporarily placed in a dedicated inspection network segment, where it is checked for virus infections, antivirus software version, OS patch application status, and other security conditions.
Step 2: Connection/Isolation
Devices that pass the inspection without issues are connected to the main internal network. Devices with detected issues remain isolated within the inspection network.
Step 3: Remediation
For isolated devices, a dedicated remediation server administers fixes, such as updating antivirus software or applying OS patches. After remediation, the device is inspected again by returning to Step 1.
When implementing a quarantine network for remote access endpoints, deploying F5 BIG-IP Access Policy Manager (APM) can be highly effective. APM includes functionality to check endpoint security requirements before granting access.
