Securing Debian Manual too old?

[Stephan Seitz <stse+debian@rootsland.net>]

Hi!

I found the Securing Debian Manual 
(https://www.debian.org/doc/manuals/securing-debian-manual/index.en.html).  
This version is from 2017.

It has „Chapter 6. Automatic hardening of Debian systems” which mentions 
Harden packages and Bastille. None of these packages exist anymore in 
Debian 11 or 12.

https://bastille-linux.sourceforge.net/running_bastille_on.htm#debian 
lets you follow a link to http://packages.debian.org/bastille but without 
results.

So what happened here?

Many greetings,

	Stephan
