Soal Sistem Terdistribusi ( Exercise 13.14 )

What security issues are liable to be relevant to a directory service such as X500 operating within an organization such as a university? 

Answer :

There are two main security issues of relevance to a name service. The first is the question of who may create and modify an entry for a given name. It is important that malicious users cannot create bogus entries or alter stored attributes without permission. It is equally important that administrative boundaries in the name space are respected.

The second issue is privacy. In general, users may want only privileged principals to read their attributes.
