Methodology Process Flow of a SLAD Information Systems Survivability Assessment

摘要

The Information Systems Survivability Assessment (ISSA) is a process of analytical steps that the Survivability/Lethality Analysis Directorate (SLAD) of the U.S. Army Research Laboratory (ARL) applies to networked Automated Information Systems (INFOSYS) of military interest The ISSA Plan for a particular system is a focused plan that has been designed to provide the decision-makers the necessary information with which to make informed decisions concerning the vulnerabilities and susceptibilities of the system to Information Operations (IO) threats. The ISSA is a multiple-phase effort; these phases are intertwining tasks. Each of these tasks depends upon the others. The plan is formulated in various phases to help the decision-makers modify the necessary hardware and software within the program cycle to meet the necessary survivability requirements. The ISSA culminates with protection measures being recommended to identify and minimize the impact of the IO threats on system performance. By addressing the IO threats, the system will signfficanfly improve its survivability by planning for both the avoiding and withstanding of potential problems with IO-based threats. This report discusses the ISSA process in detail and shows how each small task dovetails into the larger effort.
