Increasing Security of UNIX Information Services

Abstract

Internet Information Services are an integral part of today's
computing society.  People rely on these services for receiving
and distributing information and data via the Internet.  Information
Servers are often the public face for companies on the Internet,
and as such, are often the target of illegal activities by computer
intruders.  Due to this unwelcome attention, it is imperative that
a high level of security is maintained on all Information Servers.
This document describes some techniques that help reduce
the impact in the event an illegal intrusion occurs.
