In this movie, learn how to implement proper network security for the users of this installation of Red Hat Enterprise Linux.
- In this video, we'll work with the new dynamic firewall…that comes with Red Hat Enterprise Linux 7, firewalld.…Firewalld replaces the iptables interface.…Even still, iptables is available…in Red Hat Enterprise Linux 7.…Firewalld uses zones and services…instead of chain and rules.…It allows for better security rules management…because it allows configuration changes to be executed…without stopping the current connections.…Before we get started, let's make sure…that the firewalld service is running.…
To do this, we'll type systemctl followed by status…and the service name firewalld, or "firewall D,"…and hit Enter.…Looks like this service is currently loaded and active.…If you didn't have it loaded and running,…you would use the systemctl command…to start and enable the firewalld service.…You can see how to do that in a previous video.…Since we know it's active and running,…let's check the firewall state.…To do this, type firewall-cmd, for command,…followed by --state.…
That shows us that it's running.…As I mentioned, firewalld uses zone management…
