BGrep and BDiff: UNIX Tools for High-Level Languages

The rise in high-level languages for system administrators requires us to rethink traditional UNIX tools designed for these older data formats. We propose new block-oriented tools, bgrep and bdiff, operating on syntactic blocks of code rather than the line, the traditional information container of UNIX. Transcending the line number allows us to introduce longitudinal diff, a mode of bdiff that lets us track changes across arbitrary blocks of code. We present a detailed implementation roadmap and evaluation framework for the full version of this paper. In addition we demonstrate how the design of our tools already addresses several real-wold problems faced by network administrators to maintain security policy

Security Policies in OSI-Management - Experiences from the DeTeBerkom Project BMSec

Security problems of network management applications are well known, and some of their solutions are specified in the OSI X.700 series. However, there is little experience with implementations of the respective security functions. This paper provides a critical view on the OSI standards of authenti cation and access control for management applications. A special focus is on security policies. Another focus is on our experience with our implementation. Key Words Distributed management, access control, authentication, security policy, development toolkits for management (OSIMaDE) and security (SecuDE). 1. Overview The operation of communication networks requires expensive management. Therefore, already some years ago both OSI and Internet have specified models, protocols, and services of network management in the X.700 series and in the SNMP, respectively [Rose 91, Stall 93]. The distinguished feature of network management is the distribution of its service. While responsible manager..
