Threat Modelling for Active Directory
This paper analyses the security threats that can arise against an Active Directory server when it is included in a Web application. The approach is based on the STRIDE classification methodology. The paper also provides outline descriptions of countermeasures that can be deployed to protect against the different threats and vulnerabilities identified here
Internet X.509 Public Key Infrastructure Operational Protocols -- LDAPv3
This document describes the features of the Lightweight Directory Access Protocol v3 that are needed in order to support a public key infrastructure based on X.509 certificates and CRLs
The PERMIS X.509 Based Privilege Management Infrastructure
This document describes the PERMIS X.509 Based Privilege Management Infrastructure, which is a trust management system as described in RFC 2704 [2]. The PERMIS Infrastructure is compared with the AAA Authorisation Framework described in RFC 2904 [4], and is shown to be compatible with it
A Method for Collecting Case Study Information via the Internet
The Internet is rapidly becoming the communications infrastructure. With its advantages of speed, availability, and `different time, different place' mode of communication, it can be successfully harnessed to accomplish tasks that previously required face-to-face meetings. Such meetings can consume large travel budgets and staff time, and therefore alternative mechanisms that achieve the same results for less cost should be welcomed. One of these new uses of the Internet is to collect case study material. This paper presents a method that has been successfully employed by the author to collect 15 case studies of X.500 implementations. The method described herein consists of three phases: preparation, correspondence and documentation phases. Each of the phases is described, and the author also presents useful tips that he gained during the course of his studies. The method should provide future researchers with a framework which can be successfully employed to productively utilise the resources of the Internet
Important Lessons Derived from X.500 Case Studies
X.500 is a new and complex electronic directory technology, whose basic specification was first published as an international standard in 1988, with an enhanced revision in 1993. The technology is still unproven in many organisations. This paper presents case studies of 15 pioneering pilot and operational X.500 based directory services. The paper provides valuable insights into how organisations are coming to understand this new technology, are using X.500 for both traditional and novel directory based services, and consequently are deriving benefits from it. Important lessons that have been learnt by these X.500 pioneers are presented here, so that future organisations can benefit from their experiences. Factors critical to the success of implementing X.500 in an organisation are derived from the studies
