Also, you can see the product info at "http://iss.net" /ISS Running ISS on your systems will provide you with the / same information an attacker would obtain, allowing you / to correct vulnerabilities before they can be exploited. / Note that the current version of the software is known / to function poorly on some operating systems. / / ISS may be obtained via anonymous FTP from ftp.uu.net / in the directory /usenet/comp.sources.misc/volume39/iss.
