  • Opendnssec Initial Deployment Guide W

    OpenDNSSEC Initial Deployment Guide W. Matthijs Mekking November 17, 2014 Abstract OpenDNSSEC is a policy-based zone signer that automates the process of keeping track of DNSSEC [1], [3], [2] keys and the signing of zones. The goal of the project is to make DNSSEC easy to deploy. The software has a lot of configuration options that can be tweaked but that requires some knowledge about DNSSEC. Some users might just want to deploy DNSSEC without knowing what is under the hood. If you are that person, this deploy- ment guide will help you set up OpenDNSSEC and provide simple guidelines for adding and removing zones, as well as some other quick guides. Contents 1 Starting OpenDNSSEC for the first time 1 1.1 Dependencies . .2 1.1.1 SoftHSM . .2 1.2 Installation . .2 1.3 Configuration . .3 1.3.1 Key and Signing Policy (KASP) . .3 2 Adding a zone 4 2.1 OpenDNSSEC as a bump-in-the-wire . .5 3 Publish the DS 5 4 Migrate a zone to OpenDNSSEC 6 4.1 Export the keys . .7 4.2 Add the zone to OpenDNSSEC . .7 5 Feedback 8 6 Acknowledgements 8 1 Starting OpenDNSSEC for the first time OpenDNSSEC [4] will run on most Linux, BSD and Solaris operating systems. The community provides binary packages for several platforms which makes installation even more easy. This guide however assumes those packages are not available. 1 STARTING OPENDNSSEC FOR THE FIRST TIME 1.1 Dependencies If you have found a nice system to run OpenDNSSEC on, it is time to install its dependen- cies.
