Everything that business or government does with computers or communications becomes part of the social and economic infra-structure of the twenty-first century. Much of the configuration and operation of this novel and critical infrastructure will be in the hands of the system and network administrators. They are often the first to be called when the infrastructure is stressed or breaks, but their training is often on-the-job, remedial, and late. Although they understand the weaknesses and limitations of their materials all too well, they are rarely taught how to compensate for those weaknesses. Out of necessity, their security approach tends to be reactive and remedial.
This presentation will provide system and network administrators with a set of broadly applicable strategies and proactive approaches they can use to protect systems from outside interference and contamination, provide appropriate application con-trols, and protect their networks from undesired traffic. Among other things, it will address policy and service-level agreements; when to plan and for what; effective use of access controls; strong network perimeters and how to compensate for leaks; and how to use weak materials to build strong systems.
