For ease of use, many pieces of software are insecure in their default settings. Not realising this, users in all the major categories - academic, industry and hobbyist, will often run said software in a configuration where vulnerabilities are visible. With the advent of data lakes came the need to store much more data. Often that amount of data needs much larger databases and, to achieve affordable scale, those databases are commonly distributed. This tutorial takes one such open-source distributed database and teaches attendees both how install it with recommended settings and then how to secure it.
