The post from 1997 assumes &#x2F;var&#x2F;log  is not vulnerable tampering; assumes that the syslogd or access to the socket or port it&#x27;s writing to is not vulnerable to compromise; and assumes that all signifcant programs write to a log.<p>The world is much more familiar with UNIX in 2015; I trust that today no one would rely on &#x2F;var&#x2F;log.<p>My approach would be to look at periodic memory dumps and look for anomalies there.<p>And not to rely on the integrity of utilities stored the system that you are analyzing.
