With this configuration, you will always have a long-term copy of your logs available - even if the bastion host is compromised. Try running the last command which will, by default, display the contents of /var/log/wtmp:Ĭapturing login information to an aggregatorĪt the most basic level, you will want to find a way to capture authentication logs - both to the local bastion host as well as a secondary device. The btmp file, typically located at /var/log/btmp, keeps track of failed login attempts. This file is a historical account of utmp activity, and located at var/log/wtmp. The files is typically located at /var/run/utmp. Utmp also logs the system boot time, logins and logouts, and other important events. The utmp file keeps information about who is currently using the system, which is important since several users may be using our bastion host at the same time. Now that we have a bastion host and bastion guest to play with, lets go over some of the basic sources of information we might want to configure to create a logging and auditing system. Understanding the basic sources for audit information In this third and final part of this series, we will take a deep dive into configuring the hosts for logging verbose data, and then conclude by sending those logs off to a cloud provider for long-term storage and access. So far in this series, we have stood up two virtual bastion hosts, configured some initial firewall rules, and configured SSH access and SSH forwarding to allow for easier management of the systems. How to configure our bastion hosts to gather verbose logging data and send it off site to a cloud service.In this post, we will show you how to create an SSH key for your bastion host and look at ways you can streamline the bastion host login process without compromising the security of the key.This post shows you how to create Linux virtual machines in Amazon Web Services, setup virtual networking, and create initial firewall rules to access the hosts.The full tutorial is split into three parts: Part 1: Creating your bastion hosts In this final post of the tutorial, we will configure our bastion hosts to gather verbose logging data and send it off site to a cloud service.
