Questions about UNIX viruses

[Link_-_APO at cup.portal.com]

Hi,
     I myself just finished reading a new and enlightening book on UNIX system 
security titled "UNIX System Security - How To Protect Your Data and 
Prevent Intruders". Rik Farrow is the author and Addison Wesley is the
publisher.
     For those of you who are flaming about the sendmail and finger
'bugs', the chapter on Communication and Network Security includes
the stories behind those security problems.
