SPI/UNIX user manual: Security Profile Inspector
T Tessin · 1989
The Security Profile Inspector (SPI) is a software security system for computers running the UNIX operating system. Its purpose is to assist system managers and computer security officers in providing and monitoring the security of a computer system. SPI inspects various aspects of the computer system and reports on inconsistencies or insecure features. SPI will also periodically check certain security features and will warn the system manager if and security policies are violated. Currently, SPI provides three major security inspections: the password inspector, the critical file integrity inspector, and the file permissions inspector. Future versions of SPI will include other areas of computer systems security. This User Manual is divided into two primary sections. The first section explains each of the three main functions of SPI. The second section contains detailed instructions on how to actually run this software.
