illuminIT Network Traffic Capture can help the Data Center Manager to configure firewalls

December 28, 2017

illuminIT Network Traffic Capture can help the Data Center Manager to configure firewalls, both organization firewalls as well as server firewalls. Specifically, one of our customers used illuminIT to quickly and easily configure server firewalls – for Windows servers the Windows Server Firewall, and for Linux servers – the default Iptables firewall.

Before using illuminIT, the system administrator used mainly the netstat command to check the current connection list in order to configure the firewall. This list provides a snapshot of the current status, so many of the communications are missed. The result was firewall misconfigurations, which eventually caused many of the local server firewalls to be left unmanaged.

By using illuminIT topology maps all connections to and from a server can be viewed and exported, so it is easy to use them for the firewall configuration. By exporting the server connection maps into Excel and modifying them into a batch command, the Data Center Manager can create a full configuration of a Windows Server Firewall or Linux Iptables within minutes, taking into account all recent communications so that no valid connection is missed and blocked.

This allows the Data Center Manager to make effective use of the default firewalls installed on any server and workstation, therefore protecting each one of them without interrupting anybody’s work.
