Found this rather interesting new and freely distributable digital security magazine.
It has some advertising (offcourse it has ) but the articles are interesting and the overal magazine looks promising.During the second day of Infosecurity Europe 2005 Conference, HNS announced the first issue of (IN)SECURE Magazine, a freely available, freely distributable digital security magazine in PDF format
One of the topics is about "The 5 keys to locking your Linux system down" I would be very interested to see what you Linux specialists think of the article
The topics covered and the link to the download are on THIS page.
Have fun reading,
