Using Built-in Policy Installer in Firewall Builder
This article demonstrates how Firewall Builder can help you automate the process of deployment and activation of the generated firewall configuration. After firewall configuration has been generated by one of the policy compilers and saved in a file on disk in the format required by the target firewall, it needs to be transferred to the firewall machine and activated. This function is performed by the component we call "Policy Installer" which is part of the Firewall Builder GUI.
Chrooted SSH/SFTP Tutorial (Debian Lenny)
Since version 4.8, OpenSSH supports chrooting, so no patches are needed anymore. This tutorial describes how to give users chrooted SSH access. With this setup, you can give your users shell access without having to fear that they can see your whole system. Your users will be jailed in a specific directory which they will not be able to break out of. I will also show how to use chrooted SFTP.
Using Built-In Revision Control In Firewall Builder
Firewall Builder GUI has built-in revision control system that can be used to keep track of changes in the objects and policy rules. If data file has been added to the revision control system, every time it is saved, the system asks the user to enter a comment that describes changes done in the file in this session and stores it along with the data. The program also assigns new revision number to the data file using standard software versioning system whith major and minor version numbers separated by a dot. When you open this data file next time, the program presents a list of revisions alongside with dates and comments, letting you choose which revision you want to use. You can open the latest revision and continue working with the file from the point where you left off last time, or open one of the older revisions to inspect how the configuration looked like in the past and possibly create a branch in the revision control system. Here we take a closer look at the built-in revision control system.
