Description

This book does not exist yet. This item is to sponsor me writing it. Ebook sponsors get their names in the ebook versions of the book. They will receive a free copy of the completed ebook in epub, mobi, and PDF, all DRM-free.

My goal is for this to be a shorter book, like the first DNSSEC Mastery, Tarsnap Mastery, or the first Sudo Mastery. I don’t want to write another doorstop like the Networknomicon or FreeBSD Mastery: Jails for a while.


Cache poisoning? Rebinding? Hijacking? Spoofing?

You don’t have time for this crap.

Anyone who wants to attack an organization’s network starts by investigating the Domain Name Service. DNS Security Extensions, or DNSSEC, hardens DNS and brings it into the 21st century. The first edition of DNSSEC Mastery helped thousands of sysadmins secure their networks. This new edition offers guidance on current standards and new developments.

You will:

• Understand what DNSSEC gives you, and what it doesn’t
• Configure your servers to resist attack
• Verify your environment supports modern DNS
• Debug DNSSEC and the Chain of Trust
• Configure your servers to resolve DNSSEC
• Conceal zone data with NSEC3
• Cryptographically sign your zones and attach them to the Chain of Trust
• Roll over keys to maintain security
• Implement DNSSEC on private networks
• Provide DNS over HTTPS (DoH) and DNS over TLS (DoT) to your clients

And more! DNSSEC Mastery transforms DNS from a security risk into a solution.
