If you want a full copy of the manual you can either download the text version or the PDF version from the Debian Documentation Project's site. These versions might be more useful if you intend to copy the document over to a portable device for offline reading or you want to print it out. Be forewarned, the manual is over two hundred pages long and some of the code fragments, due to the formatting tools used, are not wrapped in the PDF version and might be printed incomplete.

The document is also provided in text, html and PDF formats in the harden-doc package. Notice, however, that the package maybe not be completely up to date with the document provided on the Debian site (but you can always use the source package to build an updated version yourself).
